Use our AI, or bring your own key
Runs are billed in credits when you use the built-in AI models. Prefer your own LLM API key (BYOK)? That stays free — credits only cover the built-in models.
100 trial credits at signup
One-time welcome credits for every verified account — enough to see Small Tester work on your own site.
10 free credits monthly
Every free account gets a small monthly credit refill — keep an occasional test running without paying a cent.
