001ManifestoAn autonomous SDLC, not another agent chat.

The product team
that doesn't need standup.

Mergecrew is a multi-agent crew that runs on a cron against your real repository. Spec, build, deploy to dev, scan for regressions— every weekday by lunch. One decision arrives in your inbox at 5pm: promote to production, or don't.

002 — The Crew

Five specialists.
One weekday.

Four agents specialize, one human gates. A cheaper Reviewer catches the obvious before you do, so you read fewer bad PRs. Promotion to prod is the only step Mergecrew will never automate — by design, not by configuration.

003 — The Loop

Not an agent.
An assembly line.

Most autonomous-coding tools take a ticket and produce a PR. Mergecrew owns the entire cycle around that work — runs it daily, deploys it, scans it, and hands you a single moment of judgment per day.

01 · 09:00

Spec

Planner reads intent, the repo, and yesterday's bugs. Drafts a small changeset.

02 · 09:04

Build

Coder opens a draft PR. Reviewer loops back on request-changes.

03 · 09:18

Deploy

Pluggable adapter ships the PR to dev — Vercel, Fly, GH Actions.

04 · 09:22

Scan

Scanner exercises the preview URL. Regressions filed for tomorrow.

05 · 17:00

Digest

One email. Today's diffs, today's risks, today's verdict.

06 · GATE

Human

Approve, defer, or roll back. The only step Mergecrew won't automate.

07 · SHIP

Prod

Promoted on your nod. Tagged, deployed, archived in the run log.

Product invariant. Production promotion is always a human decision. Not a setting — a property of the system. Try to disable it; the build fails.

004 — Surfaces

A timeline of work,
not a tab of chats.

Three things you'll actually open: today's timeline, the daily digest, and the approval card. The rest stays on the box — it does its job whether you're watching or not.

No dashboards to learn. No tickets to triage. Just a verdict per day, delivered the way the news used to come.

005 — Self-host

Five minutes.
No card. No key.

One docker compose brings up Postgres, Redis, four backend services, and the web app. The seeded demo project runs the full multi-agent loop against a deterministic stub.

No LLM provider required to see the loop end-to-end. When you're ready, plug in Anthropic, OpenAI, Bedrock, or local Ollama and flip MERGECREW_DEMO_MODE=0.
