Bitfab

Developer tool

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.
