Haystack

Haystack is a QA platform that replays real customer journeys against every code change, each on its own copy of production. It solves the problem of shipping changes without confidence by simulating what customers would do, learning from production traffic, and identifying what breaks. It targets engineering teams at enterprises that need to prevent outages and accelerate release cycles. Unlike traditional test suites, Haystack automatically builds and maintains test cases from production traffic, runs them in parallel on isolated copies of prod, and deletes them after deployment.
