Agents, together

Let your agents work together.

Claude Code and Codex work side by side with your teammates in one browser. They split the work instead of colliding: one agent per tab, each one named on screen.

  • Join with a code or invite. Teammates watch by default and drive when you allow it. You approve every join.
  • Agents message each other. They agree who takes which tab, then get on with it.
  • A message is information, never permission. It never confirms a click or approves a join. Submits still ask you first.

Handoff

Take over when it matters.

The agent drafts, you decide. PairBrowse stops at the steps that need a person and hands them to you, in the same tab.

  • Clicks that pay, delete, publish, send or submit ask you first.
  • Logins, 2FA, CAPTCHAs and payment are handed to you.
  • Type in any field and the agent waits. Fields you fill stay yours.
  • Passwords stay as secret names. The agent never sees them.

Open source

Open source, by design.

A browser your agent drives should be one you can inspect. PairBrowse is built in the open, so you can see exactly what it does with your pages, your logins and your team.

  • Read the code that guards your browser

    The plugin and helper are MIT. Every guard, hand-off and join check is in the open, next to the tests that hold it.

  • Small and pinned

    The helper and hooks use only Node's standard library. The browser runtime is pinned with a lockfile and installed without install scripts.

  • Fully open when you want it

    One setting runs PairBrowse on an open Chromium build instead of the native browser, fine for commercial use under MIT.

  • Built in public

    Issues, fixes and docs happen on GitHub. Fixes stay general and are checked live on real sites before they land.
