77% of AI agents fail in production from undetected regressions.
AgentProof is the test harness for people who ship AI agents: replay real conversations every time you change a prompt or model, and catch the regression before your users do.
Turn real conversations into test cases with deterministic checks (contains, regex, JSON schema, tool calls) or an LLM-judged rubric.
Replay every test case before you ship a prompt or model change. See exactly which cases regress, with a diff against your last baseline.
Sample real production output and catch schema rot — valid-looking, semantically wrong responses — before it ever hits an error log.
