About Commons
Last updated 6 November 2026
In short
- Commons hosts the apps, tools and pages people build with AI agents, and gives each one a link.
- Anyone with the link can use it in the browser, with their own data, or fork it and adapt it with their own agent.
- Sign in with GitHub or Google. Google sign-in only shares your name, email and picture.
What Commons is
Commons is a free website where people host and share the small apps, tools and pages their AI agents build, such as Claude, ChatGPT, Codex, Cursor or Grok. You connect your agent once, ask it to publish what it made, and Commons gives it a page and a link. Anyone you send the link to can open it in their browser with nothing to install, use it with their own data, or make their own copy (a fork) and change it with their own agent. The original maker always keeps the credit.
Who it's for
People who build things with AI agents and want to share them with friends, classmates, teammates or a club: a training plan for three friends, a study group's case briefs, a class timeline, a fantasy league vote board, a shared chore list. You can browse examples on the home page without an account.
How it works
- Connect an agent. Paste one address (
/mcp) into your agent and approve it once. - Publish. Your agent uploads what it built. Every version is kept, and each app runs in its own sandbox, on its own web address, away from your account.
- Share. Keep it private, share a link, invite chosen people, or list it for the community. Each person's data stays in their own copy.
- Fork. Anyone you allow can copy an app and have their agent adapt it. Commons keeps track of where each copy came from.
Signing in
You can sign in with GitHub or Google. With Google, Commons only receives your name, email address and profile picture, to create your account and show your name on what you publish. It does not access Gmail, Drive, Calendar or any other Google data. The Privacy notice has the details.
What Commons is not for
Commons hosts apps and pages that people choose to share. It does not generate images or media, and it may not be used for sexual, abusive or non-consensual content, phishing, malware or anything else in the Acceptable use policy. Anyone can report an app, and we remove what breaks the rules.
Who runs it
Commons is run by the Commons team, based in the Netherlands. Questions: hello@commonsbuild.com. Privacy: privacy@commonsbuild.com.
