Software that
builds itself.
Skip the tickets and the step-by-step prompts. Aion plans, writes, tests, and opens the PR — then watches production and gets sharper with every pass.
Zero spam — one note the day your seat is ready.
MITOpen source under the MIT license — the full loop is free forever on your machine.
What is Aion
An autonomous developer, not a chatbot.
Work arrives as missions. Missions execute as cycles. Production itself files the next mission. You give intent and sit at the gates — Aion does the rest, and gets sharper every pass. Five nouns are all you need to keep straight.
Mission
One sentence of intent — “export reports as CSV”, or a live Sentry error. Ranked by severity, deduped by fingerprint.
Cycle
One full pass of the loop executing a mission. Checkpointed to disk after every step — kill it mid-run and it resumes.
Monitor
Polls Sentry and PostHog and turns real incidents into missions automatically. Production files the next job.
Playbook
Your per-repo contract: how to test, build, run, deploy — and which steps wait for a human.
Brain
The agent that thinks (Claude by default). Each phase is a fresh process: no chat history, no hidden state.
It scopes the task, writes the code, and opens the pull request, then keeps watch on production. The moment something breaks, it traces the cause and ships the fix. Every pass it rewrites its own playbook and goes again, until the loop no longer needs you.
Everything an engineer does — end to end.
Delivers working code
Give it an outcome instead of instructions. It designs the change, writes it, proves it with tests, and opens the PR.
Lives in your repo
Branches, commits, pull requests, merges — all inside your repository, matching the conventions you already use.
Heals production
It tracks Sentry and PostHog, traces a failure to its root cause, and ships the patch — no ticket filed, no one paged.
Teaches itself
It writes new skills, rewrites its own workflow, and banks what it learns each pass — an agent that keeps upgrading the agent.
The app
Watch production work itself off.
Every signal becomes a ranked mission. Every mission runs as an auditable cycle. You approve at the gates — one click — and inspect a branch, a PR, a deploy id, and a verdict for each one.

How it works
One mission. One cycle. Eleven phases.
Hand it a mission — a sentence of intent, or a live Sentry error. It runs a cycle through the same pipeline every time. Failures never fall forward; they loop back to code. You sit at the two gates, not in the loop.
Mission
One sentence of intent, ranked by severity and deduped in a queue. The same error never opens twice.
Cycle
One pass of the loop. Checkpointed to disk after every phase — kill it mid-run and it resumes.
Gate
A human pause for one-click approval. Merge and deploy wait for you; everything else is autonomous.
