Commons puts your running app on a shared canvas. Your team comments on the real screens, hands feedback straight to a coding agent, and the reasoning stays attached to the work instead of scrolling away in chat.

When agents can ship a change in minutes, the design file is out of date by lunch. Commons moves the conversation onto the thing that actually runs, so feedback lands where the work is and nobody reviews a screenshot of last week.
What it does
One canvas showing the app that actually runs, for the whole team that argues about it.
Click anywhere on the live app to start a thread anchored to that screen and route. Guests join from a link, no account.
Hand a comment to your coding agent. It picks up the screen, the route, and the conversation, and reports back with a preview link.
Send one link. Testers use your live app in the browser, and success rates, heatmaps, and paths come back to the same screens.
Comment
Every screen on the canvas is your real app, rendered from a local dev server or a deployed preview link. Click anywhere to leave a comment anchored to that screen and route, not to a rectangle that used to look like it.
Agents
Hand a thread to your coding agent and it picks up the whole context: the screen, the route, the conversation. It works on its own branch and reports back, so review stays a conversation instead of a ticket handoff.
Narrate
Commons reads your comment threads, test results, and code history, then drafts the thinking behind each screen and cites where every claim came from. You approve what is right, and the rationale rides along with the work for whoever asks next quarter.
User tests
Write tasks, send one link. Testers open your live app in the browser with no account and no install. Success rates, times, and the paths people took come back to the same canvas the team is already working on.
Flow
Screens laid out by how deep they sit in the journey, joined by the paths people actually took. Nobody maintains it: the edges come from recorded sessions, so the map is a record rather than a diagram someone last touched in March.

How it works
Connect GitHub and your deployed repos appear as projects on their own. Or point the Mac app at a repo: routes are found and every screen lands on the canvas. A monorepo asks which app you meant. No repo, no GitHub? Paste a preview URL.
Teammates sign in on the web and see the same screens with no install. For anyone outside the team, share a link that needs no account at all.
Feedback becomes a thread, a thread becomes an agent draft, and the draft becomes a preview link anyone can open before it merges.
Who it's for
The people who argue about a product rarely share a tool. Designers work in a file, engineers work in the repo, and PMs work in whatever screenshot reached them last. Commons is the same live app for all three.
Access
One product, three levels of access. Nobody installs anything they do not need, and nothing is shared wider than you chose.
Questions
No. Whoever has the repo runs it locally and everyone else sees the same screens through a deployed preview link. Designers, PMs, and stakeholders never touch a terminal.
Only when you ask. Commons never works on a dirty tree, never merges for you, and never stores git credentials. Agent drafts live on their own branch and you decide what happens next.
The desktop app is macOS today, and it is what you need to run dev servers and agents locally. Everything else, including the full canvas, works in any modern browser.
No. Figma is where you explore what does not exist yet. Commons is where the team works on what already runs. Most teams use both, and the handoff between them gets shorter.
Your deployed repos appear as projects on their own: the next production deploy of a repo Commons has never seen becomes a project, preview link and all. Deploy events keep those links current, and agents get a place to run when no laptop is awake. Commons reads only the repos you picked during install, matches them only inside the workspace that installed it, and never recreates a project a person archived or deleted. You can run everything without it and paste preview URLs by hand.
Commons asks which one the project is rather than picking for you. They are two projects: add the repo twice and choose a different app each time.
Nothing while Commons is in preview. Agent runs use your own Anthropic or OpenRouter key, so you are never billed through us for model usage.
Open Commons in the browser and add your first project in a couple of minutes. Bring the people who have opinions about it.
