One reagent is free.
Add more as you grow.
Every plan dips grounded personas into your preview deploy and lands one comment on the PR. Start with Sam at no cost, then add reagents and daily reviews as your team grows.

How plans and reviews work.
What counts as a review?
One reagent reviewing one pull request, counted when the review starts, whether or not it finds anything (a clean pass is still a review). A three-reagent swarm on a PR uses three reviews. A preview we cannot reach (still building, behind a login) costs nothing. Daily limits reset at midnight UTC, monthly on your billing date.
Is there a free trial?
The Free plan is genuinely free with no card required. Install the GitHub App, open a PR, and Sam reviews it. Upgrade when you want more reagents or more reviews per day.
How do I upgrade to a paid plan?
Self-serve checkout is still in the works. For now, start on the Free plan and contact us to move to Pro or Lab. We will get you set up.
Do I need Vercel?
Litmusly finds your PR preview through the GitHub Deployments API, so it works with Vercel and any host that publishes deployment statuses.
What is the Enterprise BYOK plan?
Bring your own model API key and pay the provider directly, plus a per-run platform fee. It is on the waitlist while we finish wiring provider billing. It is not purchasable yet.
