How it works
Each ticket gets a plan, a build, and a PR you review.
- 01
Write the ticket
A sentence is enough. Fredrin drafts the plan and the acceptance checks — edit them, or run it as written.
- 02
Run it
It gets a branch, a real git worktree, and its own agent session. It builds, runs the acceptance checks, and rebases when main moves ahead.
- 03
Review the diff
Finished work lands in Review with the diff and the PR — the conflict fix as its own diff. Ship it, or send it back.
Interactive demo
Try it now
Open a ticket, start building, and watch an agent take it from plan to diff — each on its own branch and worktree. Click around below.
An all-in-one platform for teams
The board that runs the agents, the workflows that shape them, the machines that host them, and every app you review the work in — one window.
What you keep
Control, not just parallelism — three facts about what an agent can and can’t do to your repository.
Every ticket gets its own branch and a real git worktree.
Agents never see each other's working copy, and never touch your main branch. Isolation is filesystem-level, not prompt-level.
Agents open pull requests. They never merge.
Merging is the human's gate; the agent never crosses it. Nothing reaches your base branch until you press the button.
A red check is reported, never hidden.
Each Worker runs the ticket's acceptance checks as its final act and reports real exit codes, never assumed. The pull request opens either way, with the failing checks written into it — so you review the red instead of hunting for work that never surfaced.
We ship Fredrin from a Fredrin board
Every change in the changelog was written by agents on our own board, reviewed by one person, and merged.
