feat: forward cloud workspace ports to your computer, and list forwards with superset ports - #9493
Forward cloud workspace ports to this computer (desktop). Conductor-style: nothing is forwarded until someone clicks Forward. The control is in the Share popover ("Ports on this computer"), the sidebar ports card and the top-bar ports dropdown. If the local port is busy, Forward picks the next free one.
superset ports (realtime + API + CLI). The desktop reports its forwards to the workspace's realtime hub. A new read-only cloudWorkspace.forwards procedure and superset ports list / superset ports port <n> show who forwarded which port to which local address. Agents inside a cloud workspace can use these.
Fix: forwards now reconnect after the host refuses a session (e.g. the sandbox was asleep). This also affects remote-device forwarding.
Part 1: Forwarding cloud ports (desktop)
Why
Cloud workspace ports weren't reachable from the laptop at all. Remote-device forwarding (relay, #6858) skipped cloud workspaces, and the sidebar never even listed their ports.
How
Same engine as remote-device forwarding (PortForwardManager plus the /fwd mux on host-service), but routed through the sandbox gate with the workspace's ticket. SandboxAccessProvider hands the ticket to the main process. Gate hosts never fall back to the relay token.
Explicit forwards belong to no window. They survive navigation and end on Stop, sign-out or quit.
Busy local port: Forward tries the same number, then up to 20 higher, then any free port. The row says "5173 was in use on this computer, so it moved to 5174". Remote-device auto-forwarding keeps its existing "Use another port" prompt.
Host unreachable at Forward time (e.g. sleeping box): the forward still binds the local port and heals on the first connection that gets through.
Ports that stop being detected: forwards on them still show in the Share popover ("Not detected in the workspace right now"), so they can be stopped.
The open cloud workspace's ports now reach the sidebar. Its row comes from the cloud list, not a sidebar placement, so it was being filtered out.
Dev only: Node doesn't resolve the dev gate's *.localhost, so those connections go to 127.0.0.1 with the original Host header.
New components
CloudPortForwardActions: Forward/Stop, shared by the sidebar card, the ports dropdown and the Share section.
An agent inside a cloud workspace can't see which port people forwarded where. That mapping lives only on each person's laptop, the same way a Docker container can't see its published host port.
How
Decision
Choice
Rationale
Where the mapping lives
Per-workspace WorkspaceHub Durable Object
No sandbox release needed; box sleep doesn't lose it; existing access checks, revocation and silent-socket sweeping are reused
How a laptop's entries expire
Its WebSocket closing
No heartbeat or TTL code. Quit, sleep or network loss drops the entries; the hub's sweep removes sockets that went silent
How the agent reads it
CLI → API cloudWorkspace.forwards → hub (shared secret)
The box's CLI signs in to the API, not to realtime. The API applies the same access rule as opening the workspace
Realtime
A new forwarder connection role. It isn't presence, isn't recorded as a visit and gets no broadcasts.
Reports are stored in hub SQLite, not on the socket, because a hibernating socket's state is capped at 2 KB.
Messages over 4 KB are refused, and unchanged reports skip the write.
Losing access closes forwarder sockets, the same as viewers.
A GET on the same path, checked with the shared secret (timing-safe compare), lists forwards for the API.
Desktop
The reporter opens one socket per workspace that has explicit forwards, with the token in the Authorization header.
The backoff only resets after a socket stays up, because the hub refuses by accepting and then closing.
A 4401-refused token isn't retried until it changes. 4403 only backs off, since access can be granted later.
CLI
ports list defaults to $SUPERSET_WORKSPACE_ID, which equals the cloud workspace id inside a sandbox (checked).
ports port <n> prints bare http://localhost:N addresses, one per person, and exits non-zero if nobody forwarded the port.
Part 3: Reconnect fix (mux-session.ts)
ws emits no close after a refused upgrade, so a session that got a non-101 answer was never marked dead. The transport then kept reusing it, and the local port stayed dead until Stop and Forward. This is now fixed.
Manual QA
All of this was verified by clicking through the desktop dev app on a cloud box. The box played the role of the sandbox, through a local wrangler dev gate and a pass-through shim in front of its host-service. The shim and stub are not in this PR. A fresh Vercel sandbox still runs the released host-service, so this was the only way to exercise it.
Forwarding
npm run dev in a cloud workspace terminal → the port appears as 5173 · cloud in the sidebar card and the Share popover
Forward with 5173 busy locally → it goes straight to localhost:5174 with the "moved" note; the page loads; hot reload works through the forward
Leave the workspace → the forward keeps serving; come back → Stop → the local port is freed
Sleep/wake: box down (gate answers /fwd 500) → box back → the same local port reconnects without clicks. This failed before the mux-session fix.
The box restarted for real during testing → the app reconnected; after restarting the dev server, Forward worked
Reporting
Forward → the hub lists 5173 → localhost:5174 with the person's name; Stop → the hub list is empty (read via the realtime endpoint with the shared secret)
Not verified
superset ports list end to end against a dev API. The dev CLI's sandbox sign-in rules got in the way. The API procedure is a thin wrapper over the hub read verified above, and the CLI commands typecheck and are covered by the suite.
The fixes from the review round below weren't re-run in the app. They're covered by unit tests.
A real Vercel sandbox through the deployed gate.
Testing
bunx tsc --noEmit: desktop, realtime, trpc, cli, shared all clean
an explicit forward moves to a free port when its own is busy;
recovery after a failed first probe;
stopExplicit;
the reporter sends once per change, uses the auth header, closes when forwards end, and doesn't hammer a refusing hub;
the hub forwards store (report, prune, keep since, parse limits);
the cloud port query target.
bun run check:i18n: new strings translated in all 17 locales. The port-forwarding "Forward" has its own context so it doesn't reuse the navigation "Forward" translation.
Biome clean
An independent review pass (state machines, security, code) found no high-severity issues. Its medium findings are fixed in this PR:
sign-out now tears down forwards, reporter sockets and tickets;
the reporter's retry loop on refusals is gone;
a forward no longer gets stuck in error after a failed first probe;
forwards whose port disappeared can now be stopped.
Known Limitations
Forwards on other workspaces can't be seen or stopped from where you are. They show only in their own workspace's Share popover. A global "forwards on this computer" list is the next step.
Background workspaces still sleep. Forwarded traffic doesn't keep a sandbox awake, and the gate doesn't wake it. After sleep the dev server has to be started again.
The hub has no per-connection message rate limit beyond the 4 KB cap and skipping unchanged reports. Forwarders share the per-user presence connect limit.
"Forward a port…" for undetected ports is not included. It needs a host-service change: /fwd only allows ports attributed to the workspace.
Compatibility / Rollout
The API change is additive (cloudWorkspace.forwards, new and read-only).
Order: the realtime worker and API deploy on merge. The CLI ports commands and the desktop changes ship in their next releases. Per packages/trpc/AGENTS.md rule 9, don't release the CLI before the API is live.
No sandbox release needed. The desktop uses the existing /fwd route on today's host-service.
A desktop released before the realtime deploy just backs off when reporting; forwarding itself works.
Rollback
Revert the PR. Forwards are in memory on each laptop and hub rows are ephemeral, so there's no data to clean up.
Summary by cubic
Cloud workspace ports can now be forwarded to your machine with a click, and superset ports shows who forwarded what from inside the workspace.
New Features
Forward cloud workspace ports from the Share popover, the sidebar ports card, or the top-bar ports dropdown; nothing forwards until you click Forward, and forwards survive navigation until Stop, sign-out, or quit.
If the local port is busy, Forward picks the next free port and notes the move in the row.
Cloud forwards go through the sandbox gate with the workspace's ticket and never fall back to the relay token, so a failed ticket hand-off fails closed.
The desktop reports its forwards to the workspace's realtime hub, and a new read-only cloudWorkspace.forwards API procedure exposes them.
New CLI commands superset ports list and superset ports port <n> list per-person http://localhost:N addresses; they default to $SUPERSET_WORKSPACE_ID inside a workspace and are limited to a workspace's own sandbox callers.
The open cloud workspace's ports now appear in the sidebar.
Bug Fixes
A refused WebSocket upgrade (for example, a sleeping sandbox answering /fwd 500) left a mux session never marked dead, so the local port stayed dead until the forward was restarted; it now reconnects on the next request.
Sign-out now clears every forwarding credential and evicts cached mux sessions, so a new account or a forward still starting cannot reuse the previous account's tunnel.
The reporter's socket now has a handshake timeout, so an upgrade a proxy never completes falls into the normal retry path.
Written for commit 4c02daa. Summary will update on new commits.
Summary by CodeRabbit
New Features
Added controls to start and stop port forwards for cloud workspaces, view detected and active forwards, and open available local addresses.
Forwards can remain active until stopped, even when a port is no longer detected. If the requested local port is busy, another port may be assigned.
Workspace sharing displays forwarded-port details, including who is forwarding each port and when forwarding began.
Added CLI commands to list forwarded ports for a workspace or a specific port, with local addresses and forwarding details.
Added translations for port-forwarding controls and status messages in multiple languages.
Bug Fixes
Improved cloud workspace port detection and forwarding status reporting.
…nnect
`ws` emits no `close` after a refused upgrade (any non-101 answer, e.g.
the gate's 500 while a sandbox is asleep). MuxSession rejected `ready`
but never marked itself dead, so the transport kept handing out a session
that could never open and the local port stayed dead until the forward
was stopped and started again. Remote-device forwarding hits the same
path after a relay hiccup.
Verified in the real app against a sandbox stand-in: box down -> gate
answers /fwd 500 -> box back -> the next request reconnects. A bun test
cannot reproduce it: bun's `ws` shim closes the socket anyway.
…nd list them with `superset ports`
A desktop forwards a cloud workspace port to a local port on its own
machine; nothing else knew about it. Agents inside the workspace need
"which port is forwarded where" to point people at the right address.
- realtime: WorkspaceHub gains a forwarder connection role (not presence,
not a visit, gets no broadcasts). Reports live in the hub's SQLite, not
on the socket (hibernating socket state is capped at 2 KB), are removed
on close and pruned for connections the runtime dropped. Messages over
4 KB are refused and unchanged reports skip the write. Losing access
closes forwarder sockets like viewers. GET on the same path, with the
shared secret (timing-safe), lists everyone's forwards for the API.
- api: `cloudWorkspace.forwards` (additive, read-only) checks the same
access as opening the workspace, then reads the hub and validates it.
- cli: `superset ports list` and `superset ports port <n>` (Docker-style
bare address), defaulting to $SUPERSET_WORKSPACE_ID inside a workspace.
The hub was chosen over the sandbox's host-service so no sandbox release
is needed, box sleep does not lose the list, and a laptop that goes away
drops out by itself when its socket closes.
Cloud workspace ports were not reachable from the laptop at all. Like
Conductor, nothing is forwarded until someone clicks Forward.
- Forward/Stop for cloud ports in the Share popover ("Ports on this
computer"), the sidebar ports card and the top-bar ports dropdown.
Forwarding is per person; teammates forward their own.
- Explicit forwards belong to no window: they survive navigating away
and end on Stop, sign-out or quit.
- A busy local port is not a question: Forward takes the next free port
up (5173 -> 5174) or any free one, and the row says it moved.
- Traffic goes through the sandbox gate with the workspace's ticket;
gate hosts never fall back to the relay token. Node does not resolve
the dev gate's `*.localhost`, so those connect to 127.0.0.1.
- A forward made while the box is unreachable binds anyway and heals on
the first connection that gets through.
- The open cloud workspace's ports reach the sidebar (its row comes from
the cloud list, not a sidebar placement, so it was filtered out).
- Each workspace's explicit forwards are reported to its realtime hub
over one socket (Authorization header), so `superset ports` can answer.
Backoff only resets after a socket stayed up; a refused token is not
retried until it changes.
- Forwards whose port stops being detected still show, with Stop.
This change adds explicit cloud workspace port forwarding. The desktop manages local listeners and reports active forwards to realtime. The API and CLI expose reported forwards, and the dashboard adds controls and port listings.

The manager tracks explicit forwards, attempts nearby local ports, and exposes start and stop mutations. The reporter sends eligible forwards over authenticated WebSockets. Sandbox access passes host tokens to the main process, and sign-out ends the forwarding session.
Realtime report storage and read API packages/shared/src/realtime.ts, apps/realtime/src/utils/forwards/*, apps/realtime/src/workspace-hub.ts, apps/realtime/src/index.ts, packages/trpc/src/lib/realtime.ts, packages/trpc/src/router/cloud-workspace/*
Realtime validates and stores reports for live forwarder connections. The workspace endpoint and cloud workspace query return forward data with user details and report times.

Merge Risk: Low · up to 4c02d
Port forwarding is mergeable with bounded follow-up: discovery can disappear when host-list retrieval fails, failed ticket handoffs wait for another access refresh, and reporting omits forwards beyond 50 per workspace. Shutdown cleanup and discovery status messaging also retain minor gaps.

Review: needs changes. The desktop forwarding and realtime hub look sound, but superset ports cannot work inside a cloud workspace yet.
Highpackages/trpc/src/lib/sandbox/api-credential.ts:25: cloudWorkspace.forwards is missing from SANDBOX_ALLOWED_PROCEDURES, so the in-box CLI gets FORBIDDEN: A cloud workspace cannot call cloudWorkspace.forwards (reproduced at 0756216). Add it to the list, and consider allowing reads only for the box's own workspace.
Lowpackages/trpc/src/router/cloud-workspace/cloud-workspace.ts:538: the new procedure has no test. One test with a sandbox caller would have caught the issue above.
Nitapps/desktop/src/lib/trpc/routers/port-forwards/port-forwards.ts:32: main sends the user's JWT to any reportUrl the renderer passes. Build the URL in main instead.
Nitapps/desktop/src/main/lib/port-forward/relay-forward-transport.ts:50: the dev-only *.localhost rewrite runs in production code. Guard it with the dev flag.
Nitpackages/cli/src/lib/workspace-forwards/workspace-forwards.ts:13: in a laptop terminal, the $SUPERSET_WORKSPACE_ID default is a local id, so the command returns NOT_FOUND instead of the hint.
Re-checked at the same head (0756216) after the review was requested again: all findings still apply, nothing new. Tests (desktop port-forward/sidebar, realtime, cli), tsc, biome and check:i18n all pass. I verified the realtime /forwards endpoint locally. I could not run the desktop UI here (no cloud workspace with a gate).

If forward() follows a sync() that produced a busy or probe-error entry, reconciliation keeps the unbound entry. The explicit request therefore neither selects another port nor binds for later recovery. Apply the explicit binding behavior when promoting an unbound entry.

Resolves conflicts in the locale catalogs (both sides added entries;
kept both and re-sorted with check:i18n) and cloud-workspace.ts (main's
imports plus readWorkspaceForwards). main renamed jwtProcedure to
personProcedure, so cloudWorkspace.forwards uses it.
From the PR reviews (superset-home, cubic, CodeRabbit):
- api: allow `cloudWorkspace.forwards` for box callers (it was missing
from SANDBOX_ALLOWED_PROCEDURES, so `superset ports` failed inside a
cloud workspace), and limit a box to its own workspace. Tests cover
both; the first fails with FORBIDDEN without the allowlist entry.
- desktop: main builds the realtime report URL itself from REALTIME_URL
(now in env.main) and the organization id; the renderer no longer
chooses where the user's token is sent.
- desktop: keep `wss:` for report sockets; reconnect when pongs stop
(half-open socket); cap a report at MAX_WORKSPACE_FORWARDS.
- desktop: a forward becoming or ceasing to be explicit always emits a
change; Forward on an unbound window entry restarts it with explicit
binding; retryEphemeral returns the same snapshot as list().
- desktop: await the gate ticket hand-off before a cloud workspace is
usable, so a quick Forward never uses the relay token.
- desktop: the `*.localhost` rewrite runs in development only.
- desktop: remote ports limited to 1-65535 on `forward`.
- desktop: stale forwards are matched by full forward id; bound
localhost links open directly even when the status is an error.
- desktop: the open sandbox's ports are queried only on the workspace
page, not the cloud record page.
- desktop: the Share ports section renders inside ShareAccess (not in
the invite view); no empty row padding for automatic forwards; the
cloud/remote port labels are translated.
- realtime: the unchanged-report check compares local ports too.
- cli: the empty-list hint is shown; a non-cloud workspace id gets a
clear message instead of a bare NOT_FOUND.
- i18n: Turkish uses "port" like the rest of the app; pt-BR, uk and nl
wording fixes.

- desktop: sign-out now closes and evicts the cached mux sessions to
cloud workspaces. A session idles up to 60 s after its last stream, so
a new account forwarding the same workspace in that window could ride
the previous account's tunnel. Eviction is immediate, so a forward
made before the close lands cannot pick the old session up. Test added.
- desktop: the reporter's WebSocket has a handshake timeout, so an
upgrade a proxy never completes falls into the normal retry path.
(Not unit-tested: bun's `ws` shim ignores handshakeTimeout; Electron
runs the real `ws`.)
- desktop: a forward that is bound but in error opens and copies its
bound local port from the ports dropdown too, like the Share rows.
- cli: an invalid --workspace value gets the same clear message as an
unknown one instead of a raw validation error.

Add coverage for a stalled reporter handshake.
The reporter tests only complete WebSocket upgrades. If handshakeTimeout is removed, they can still pass while a stalled upgrade prevents forward listings from updating. Add a timeout-capable test that stalls the upgrade and verifies a retry.

Assert that closeAll closes the first tunnel.
The test checks only the new connection. If closeAll only cleared the session map, the test would pass while the first authenticated tunnel remained open. Expose the first host socket’s closure in the helper and assert it after closeAll.

If setHostToken fails before registration, forwarding can send the relay JWT to the gate in the WebSocket URL. The gate rejects that JWT, so the forward fails. Use the relay JWT only for verified relay targets; reject unregistered gate targets.

…s never get the relay token
From the latest review round:
- Sign-out now clears the relay token in main as well as the gate
tickets, so a forward still starting during sign-out cannot open a new
tunnel with the old account's token after closeAll (cubic).
- A cloud forward marks its host as a gate host itself (`viaGate`), so a
failed ticket hand-off makes it fail closed instead of sending the
relay token to the gate (CodeRabbit).
Token selection moves into ForwardTokens so the rules are tested.

Summary
This PR bundles three related changes:
superset ports(realtime + API + CLI). The desktop reports its forwards to the workspace's realtime hub. A new read-onlycloudWorkspace.forwardsprocedure andsuperset ports list/superset ports port <n>show who forwarded which port to which local address. Agents inside a cloud workspace can use these.Part 1: Forwarding cloud ports (desktop)
Why
Cloud workspace ports weren't reachable from the laptop at all. Remote-device forwarding (relay, #6858) skipped cloud workspaces, and the sidebar never even listed their ports.
How
PortForwardManagerplus the/fwdmux on host-service), but routed through the sandbox gate with the workspace's ticket.SandboxAccessProviderhands the ticket to the main process. Gate hosts never fall back to the relay token.*.localhost, so those connections go to127.0.0.1with the originalHostheader.New components

superset portsWhy
An agent inside a cloud workspace can't see which port people forwarded where. That mapping lives only on each person's laptop, the same way a Docker container can't see its published host port.
How

mux-session.ts)wsemits nocloseafter a refused upgrade, so a session that got a non-101 answer was never marked dead. The transport then kept reusing it, and the local port stayed dead until Stop and Forward. This is now fixed.Manual QA
All of this was verified by clicking through the desktop dev app on a cloud box. The box played the role of the sandbox, through a local
wrangler devgate and a pass-through shim in front of its host-service. The shim and stub are not in this PR. A fresh Vercel sandbox still runs the released host-service, so this was the only way to exercise it.Forwarding
