In development · early access

Become a design partner

We're looking for a few teams to try Rerunner on one real repository and tell us where it's wrong. You get an early look at regression tests for your coding agent; we get the evidence we need to build the right thing.

Apply by email

Opens your email app with a short template. Or write to hello@rerunner.dev in your own words.

What you get

Early access to the Rerunner check, running in your own CI on one repository.
Help writing your first suite: we'll turn three to five of your real tasks into tasks with checks you trust.
A direct line to us while you use it. When a verdict looks wrong, we want to hear about it the same day.
A say in what we build next: which agents, which checks, and what the report should show.
An honest conversation about pricing before anything costs money. Nothing is priced yet.

What we ask

Small on purpose.

One repository where a coding agent does real work, starting with Claude Code.
Three to five real tasks your agent does often, each with a check you already trust, such as your tests.
A 30-minute call to start, so we understand your setup and the changes you worry about.
Feedback: what was useful, what was noise, and what you'd pay for, if anything.

Runs call your model provider under your own account, so you'll also need a dedicated API key with a spending limit, and a CI runner without production secrets. The security page lists the setup.

A good fit

Your team uses Claude Code on a shared repository, with a CLAUDE.md, rules, skills or MCP servers that more than one person edits.
You've seen an agent behave differently after a change to its instructions or model, or you're about to make a change like that.
Your code lives on GitHub or GitLab, and your CI can run a containerised job on pull requests.

Not sure? Write anyway. A short “here's our setup” is enough to start.
