Services relying on external APIs frequently break in production due to untested edge cases: timeouts, rate limits, malformed responses, and partial data. Engineers manually write mocks and tests, but they rarely cover the breadth of real-world failure modes.
Why now: As services grow more interconnected, resilience testing is becoming mainstream (chaos engineering) and toolchains for CI/CD make automated failure-simulation viable.
A tool that automatically generates test suites and chaos scenarios for your app's API integrations: it records API interactions, synthesizes failure injections (timeouts, slow responses, truncated JSON, auth failures), creates mocks, and runs regression suites to validate graceful degradation. MVP offers an agent to capture traffic, a scenario generator, and CI-integrations to run simulated failures.
Built for: backend engineers and SREs responsible for services that call external APIs
Business model: subscription
Automated Edge-case Test & Chaos Generator for External APIs targets a medium-sized market ($100M–$1B TAM). Decent solutions exist, but there's room for differentiation and improvement.
