Ship confidently and free your engineering team to focus on creating business value.  Antithesis enables you to find and eliminate bugs that cause system downtime and difficult-to-fix correctness issues.

Our platform combines AI with advanced testing methodologies to thoroughly explore distributed systems and find the bugs that other tools miss.  The platform perfectly reproduces bugs and the conditions that led to them, dramatically reducing the time required to debug systems and enabling engineers to validate fixes with 100% certainty.   

Instead of having engineers (or AI) write more test cases, the platform enables property-based testing where you define desired outcomes.  Our autonomous AI-powered testing engine explores millions of code paths in parallel and smartly injects the kind of faults your code routinely experiences in hostile production environments.  No more testing only the "happy path" and missing the issues that will haunt you in production.
