Bitfab

Developer platform for capturing, replaying and verifying AI agent behavior: it records real production runs as scenarios including code execution, database state and external API responses, replays them against changed code with side effects mocked, and grades results with LLM and code graders, so teams can regression-test agents.

Bitfab Developer tool Sold on its own

Agent replay and regression-testing platform: SDKs for TypeScript, Python, Ruby and Go capture call stacks, database snapshots and API responses from production as scenarios, replay them locally or in Bitfab's cloud against changed code with side effects mocked, and grade each run with LLM or code graders; credit-priced plans from $75 a month billed annually with a 14-day free trial, and a custom Foundry tier.
