Ship AI agents with complete confidence.
Traditional tests only look at the final sentence. AgentDiff watches how your agent worked—catching infinite tool loops, silent hallucinations, and sudden cost surges before they ever reach real customers.
Never surprise your bill
A small prompt tweak can quietly double your token consumption. AgentDiff halts expensive runs automatically before you deploy.
Catch agents getting stuck
Identifies runaway loops and cyclical retry dead-ends in milliseconds, ensuring zero broken customer conversations.
Runs right inside your PRs
Plugs directly into GitHub Actions. If an agent drifts from its golden path, you get an instant root-cause diagnostic comment.
