Runs on your hardware, not ours

Label an issue.
Wake up to a pull request.

Mionion reads your codebase, writes the implementation, runs your tests, and opens a PR. You review it like any other contribution.

And every bit of that happens on a machine you own. The clone, the agent loop, the build — on your laptop, your build server, or your Kubernetes cluster. We never clone your repository.

How it works

01

Connect your tools

Link your issue tracker — GitHub Issues, Jira, Linear, or Asana — and your code repository. Works with your existing setup, no workflow changes required.

02

Tag issues

Add a label to any issue you want automated. Mionion monitors your tracker and picks it up within minutes — no manual handoff, no babysitting.

03

Review and merge

Mionion clones your repo, writes code, runs tests, and opens a pull request. You review it like any other contribution. Nothing merges without your sign-off.

Where the work runs

The agent runs on your hardware. Not ours.

A Mionion runner is a binary you install — a Mac app, a CLI, or a container in your own cluster. It clones the repository, runs the agent loop, executes your build and your test suite, and pushes the branch. All of it on the machine you put it on, using your git credentials and your own model API key.

Model traffic leaves from your network, not through ours. Runners need outbound HTTPS and nothing else — no inbound ports, no VPN, nothing to reach in.

On your hardware

  • The repository clone and the working copy
  • The agent loop — every model call and every tool call
  • Your build, your test suite, your linters
  • Your git credentials and your model API key
  • Outbound HTTPS only — nothing needs to reach in

On the Mionion control plane

  • Polling your tracker for labelled issues
  • Orchestrating the run, its retries, and its handovers
  • Opening the pull request and updating the ticket
  • Issue text, branch names, and run history

The control plane list is the whole of it. The issue text is what we hand the agent as its prompt, and when a reviewer requests changes we read the diff of the pull request you already published to your code host. Your working copy is never uploaded. Read how runners work.

Self-hosting is not a tier here

Everywhere else, running the agent on your own infrastructure is the enterprise SKU — a VPC deployment quoted after a sales call, at custom pricing. Mionion has no other mode. The free plan executes on your hardware for the same reason the largest deployment does: it is the only architecture we build.

Real code, not suggestions

Mionion doesn't autocomplete or suggest snippets. It clones your repository, writes a complete implementation, runs your test suite, and opens a pull request with working code. Every change goes through your standard review process.

Works while you sleep

Label issues at the end of your day. Review pull requests the next morning. Mionion processes your backlog around the clock — bug fixes, copy changes, minor features — the work that sits untouched for months.

Zero workflow changes

Keep using GitHub, Jira, Linear, or Asana exactly how you do now. Mionion plugs into your existing process with a single label. Nothing merges without your sign-off.

Understands your codebase

Mionion reads your existing patterns, follows your conventions, and writes code that fits naturally into your project. It doesn't copy from generic templates — it learns from your actual codebase.


Built for

Code that cannot leave the building

Regulated industries, customer data, source you are contractually bound to keep in house. The runner sits inside your perimeter, so the code never has to come out of it.

Small teams with big backlogs

Bug fixes, copy changes, and minor features that sit untouched for months. Mionion works through them while your team focuses on what matters.

Teams that already use issue trackers

If you track work in GitHub Issues, Jira, or Linear, you can start using Mionion with a single label. No new tools, no new processes.

Engineers who review, not rubber-stamp

Every change goes through a pull request. Nothing merges without your sign-off. You stay in control of what ships.
