Three first-render polish issues:
Code blocks jumped at end-of-stream: streaming defers the per-line
line-number markup, so the finished decorate pass inserted the gutter
column and shifted every code line right. The gutter's horizontal
footprint is now reserved with CSS while the markup is deferred, so the
final pass only fills in numbers and colors.
File references were verified twice per render and re-verified with the
wrong directory: the annotation pass's own DOM writes re-triggered its
MutationObserver, and the pass also ran before the effective directory
resolved — issuing stat probes under an empty directory and a second
time under the real one. The observer now ignores the pass's own
mutations and annotation waits for a resolved directory.
Content replacing the hydration skeleton popped in: it now plays a
one-shot 180ms fade (reduced-motion aware); cached session switches
never carry the class and stay instant. Also removed the dead
disableStaging prop and its unused pendingRevealWork threading.
Verified on a production build over CDP: a streamed code block's text
keeps its exact x-position across end-of-stream, and stat probes for a
message with file mentions are unique per path with the directory header
always present. The hydration fade path could not be exercised in the
harness (the live event stream pre-populates parts in a single-project
environment) and needs an eyeball check on a cold multi-project open.
OpenChamber is an open-source workspace for running, supervising, and reviewing AI coding work across desktop, browser, editor, and mobile.
OpenChamber gives you one place to direct agent work, understand the changes, and move them toward release. Your projects stay available when you switch devices or step away.

What you can do with OpenChamber
Goals that continue on their own
Give a session a finish line with Session Goals. OpenChamber checks the result after every turn and keeps the agent working until the goal is complete, blocked, or reaches the limit you set — even after you close the app.
Compare and combine runs
Use Multi-run to give the same task to up to five models, each in its own session and optionally its own worktree. See what each one actually built, choose the best result, or use Fusion to combine the strongest parts into a new session.
Guided changes walkthroughs
Changes Walkthrough turns a large diff into an AI-guided tour of the change. It groups related edits into steps, puts them in the order the change makes sense, and explains how the pieces fit together.
Inspect a running app
Open your app beside the conversation with Preview. Point at an element and send the agent its screenshot, styles, position, and browser errors — all the context behind “this thing here.” Desktop brings the same workflow to any web page through its built-in browser.
GitHub context from issue to pull request
Start a session from a GitHub issue or pull request with its context attached. Send failed checks or review comments back to the agent, then update or merge the pull request from OpenChamber.
Continue on another device
Open the same projects and sessions from Desktop, Web/PWA, VS Code, iOS, or Android. Check progress, answer questions, review changes, and reattach to a running terminal.
Private remote access
Pair a device with a one-time QR code and connect through Private Relay without opening ports or exposing a public server. The connection is end-to-end encrypted and can be revoked at any time. Direct connections, LAN/VPN access, Cloudflare/Ngrok tunnels, and SSH are also supported.
Track work across projects
See which sessions are working, waiting, finished, or failed, along with approvals, scheduled tasks, provider limits, token use, and costs. Organize sessions into folders and keep notes, todos, and reusable project actions nearby.
Schedule recurring work
Run a prompt once, daily, weekly, or on a cron schedule. Scheduled tasks can use Session Goals, so they continue toward an outcome instead of stopping after one response.

CLI / Server
Run OpenChamber on a workstation or server, schedule work, manage remote access, and keep it available after login
Quick start
Desktop — macOS, Windows, and Linux
Download the latest release from GitHub Releases. Desktop bundles the matching OpenCode CLI, so no separate OpenCode installation is required.
Linux releases are available as x86_64 and ARM64 AppImages. Make the downloaded AppImage executable and keep it in a writable location for in-app updates:
OpenChamber uses OpenCode to power its coding agents. We chose it because we believe it provides the best open-source agentic coding experience today: capable, extensible, and open by design.
Around that foundation, OpenChamber brings together the work that happens before, during, and after an agent run — deciding what to try, keeping it on track, reviewing the result, connecting from anywhere, and getting the change shipped.
OpenChamber is an independent project and is not affiliated with the OpenCode team.
