What is Antithesis?

Antithesis enables you to ship complex systems faster, with fewer bugs. It uses deterministic simulation, rather than traditional software testing methods, to explore the far reaches of your codebase and validate that your system always behaves as intended.
We discover the bugs others miss, and every issue we find is perfectly reproducible.
