A few useful details.
What counts as an improvement?
One bounded proposed change, prepared with code or a PR and a plan to measure it. It does not need to win an A/B test to count. Our failed retries do not use additional improvements.
What happens when I reach a limit?
We’ll notify you before your allowance runs out and provide a grace period. Active tests can finish. New work may wait until your allowance resets or you agree to upgrade. No surprise charges or automatic upgrades.
Can a small website run A/B tests?
Yes, when the specific test can collect enough data in a useful timeframe. Up to 6 weeks is recommended; over 6 to 12 weeks comes with a warning. Beyond 12 weeks, we recommend rollout and monitoring instead. Missing data is shown as unknown.
You’ll see a duration estimate and a maximum planned runtime. A test can end inconclusively. Monitoring a full rollout does not prove that the change caused an improvement.
How are visitors counted?
Your allowance counts measured visitors across your website each month, rather than page views. Repeat visits using the same permitted identifier count once; identified bots and internal traffic are excluded. Different browsers or devices can count separately. Final measurement and billing terms will be confirmed before activation.
Can I add more websites?
Keep one eligible website on Free. Pro includes up to 50,000 monthly measured visitors at $49 per website; Scale includes up to 1,000,000 at $199 per website. Paid plans are coming soon. Portfolio discounts will follow once we understand demand.
Do I need to display a badge?
No. A public Relentless badge is optional. Generated PRs include discreet attribution, and result reports are yours to share only if you choose.
Are there any other costs?
Your coding agent and hosting provider may charge separately. Pro and Scale are coming soon and are not available to purchase yet.
