Join waitlist

Your users pick the idea.
An agent builds it. You merge.

Fontan is an ideas board inside your app, wired to a coding agent in your own CI.

How it works

One idea, from a post
to a release.

Seven stages. You act at two of them, and you set the rules for the rest.

  1. A user posts an idea

    Inside your app, in their own words.

  2. Others vote

    Enough likes put it on your list. You set the number.

  3. You approveYour call

    Nothing starts before this. Decline with a reason if you want.

  4. The agent builds a branch

    Code and tests in your CI, then a merge request.

  5. Your checks run

    A gate with your rules, then the unit tests.

  6. Testers try the beta

    One tap, on their own phones. They say if it works.

  7. You mergeYour call

    Only you can. The update goes out to everyone.

You stay in control

Guardrails you control.

Post text is untrusted, so the rules run in your CI, not in the agent's head.

Merge

Only you merge

Agent can merge
Bypass label from a person only

The agent opens a merge request. The button stays yours.

Size cap

Small changes only

A bigger change fails the gate.

Scope

Paths you allow

  • app/src/main/**allowed
  • .gitlab-ci.ymllocked
  • build.gradle.ktslocked
  • **/test/**no deletes

Network, process and reflection calls are blocked too.

Checks

Must pass in your CI

  • Unit tests
  • Lint
  • No skipped tests
  • Fontan gate

Red check, no beta. Testers only see green builds.

FAQ

Questions

Can the agent ship something on its own?

No. Votes only put an idea on your list, and the agent waits for your approval. It can only open a merge request, and only you can merge it. If a beta is off, you send it back and the agent gets another try.

Can I change the thresholds and the gate rules?

Yes. Vote and tester thresholds, allowed paths, blocked patterns, the size cap and test protection are all yours to set, per app and per repository.

What does it cost during early access?

Nothing. There are no payments yet. The first developers come in by invite from the waitlist.

Whose model and compute does the agent use?

Yours. The agent runs as a job in your own CI with your model API key stored as a CI secret. Fontan never sees that key.

Does it need GitLab Duo?

No. Teams that have Duo can use a Duo flow. Everyone else runs a coding agent with their own key in GitLab CI or GitHub Actions.

Which platforms does it support?

Android first, as a library you add to your app. A web widget and iOS come after. GitLab works today and a GitHub connector is next.

What do my users see?

An Ideas board in your app with posts, likes, comments and a status on each post. While a beta is out, the post shows a button to try it. In Play apps that button opens your Play testing track.

What if an idea is bad?

You decline it with a reason, and the post shows that reason. The agent only works on ideas you approve.

Where does the data live?

Posts, votes and ratings live in Fontan, not in your issue tracker. Only approved ideas reach your repository. Your code and your model key stay in your CI.

Free during early access.
