Atrahasis is an API Client and Development Platform - the full API lifecycle in one native desktop app Most teams stitch their API workflow across separate tools: one app to send requests, another to design specs, another to mock, another to load test, and CI scripts to glue it together. Context scattered, everything cloud-locked. Atrahasis brings the whole road to production into one place — Design → Mock → Test → Scenarios → Load Test → CI/CD — with a solution for each step: • Visual API Designer — design, edit & test OpenAPI specs visually, switch to JSON/YAML anytime, and hit "Try it out" straight from the spec • Flow Runner — chain requests into automated workflows with extracted variables, assertions, retries & iterations • Load Test & Mock Server — stress-test endpoints and stand up mocks in seconds • atra CLI — run it all in CI/CD The idea behind it (the Atrahasis Code): flexibility. Every solution is independent yet works seamlessly together — use one piece, the whole platform, or run it alongside tools you already have. Nothing is strict, nothing is locked in. Native and fast on macOS, Windows (now on the Microsoft Store), and Linux. SE is free forever; Pro has a 30-day trial.
