PromptCheck ✅
CI-first Prompt Testing for LLMs (OpenAI, Claude, GPT-4)
PromptCheck runs automated tests on your prompts in CI — so you catch failures before they reach production.
Stop Prompt Failures from Reaching Production
LLM outputs can change unexpectedly – what worked yesterday might fail today. PromptCheck brings automated prompt testing into your CI pipeline, so you catch these regressions before they affect users. Think of it as unit tests for your AI prompts, running on every pull request.
How It Works (3 Steps)
Write Prompt Tests in YAML
Describe expected outputs with regex or text match.
Run Automatically in GitHub CI
Eval runs on every PR. If outputs change unexpectedly, you get a ❌ in your PR.
Fix Prompt. Merge with Confidence.
You keep LLM behavior stable — even if models change.
