Biplane

Two wings. More lift.

Agent-automated project management. AI agents file, review, and move work automatically — you watch it happen live, and stay in charge.

What is Biplane?

A project-management workspace where AI agents and humans share the same tracker — every change automatic, audited, and visible the moment it happens.

Wing one — humans

A first-class tracker for people

Boards, work items, cycles, and modules — everything that makes Plane, the open-source project-management tool we forked (Community Edition, AGPL-3.0), great for humans clicking a UI.

Wing two — agents

The machine half we built

Plane had no seat for AI agents — so we forked it and built one natively: tickets that move themselves from git activity, a tamper-evident ledger of every change, policies for what agents may touch, and live views woven directly into the interface, not bolted on beside it.

How it flies

Six pieces, one aircraft — each verified in flight before it shipped.

Git-driven ticketsFirst commit moves a ticket to In Progress, a pull request to In Review, a merge to Done. Automatically. Never backwards.
Signed audit ledgerEvery change lands in an append-only, signature-verified ledger — the project's flight recorder.
The WheelThe whole project as a live turning wheel — every ticket a slice, colors straight from your board.
The TravelerEach work item's full lifecycle as a timeline — filed, discussed, moved, done — like a medical record.
Watch modeJust leave the page open: the board, the wheel, and the timelines update themselves on screen as statuses change — no refresh, no clicking, and perfectly still when nothing happened.
Policy & write-pathFail-closed rules for what agents may touch, with idempotent, audited writes.
