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.
Redefining reliability for critical systems
Get more done with the same team
Replace the worst 50% of software engineering effort
Build braver
De-risk complex, high-impact projects like migrations and re-architectures.
Release faster
Higher code quality means shorter release cycles and more new features.
Fulfill the promise of AI code
Leverage AI code generation tools without worrying about introducing production failures.
Release safer
Prevent outages by catching unknown unknowns before you hit production.
Protect your best engineers
Keep your top engineers above the fray, building features instead of fire fighting.
Lower testing costs
Antithesis lets you cut back on canary environments and log storage.
