Antithesis has rapidly become an indispensable tool in detecting and addressing deep, hideous bugs in our code.For dependability zealots like us, this is a significant leap forward in bug-hunting technology.
Antithesis helps cloud infrastructure platforms stop outages before they happen, and ship faster with the same team.
Guarantee your guarantees
Catch the “unknown unknowns” that trigger dropped events, delivery glitches, lag spikes, and hard-to-trace outages.
Reduce testing toil
Cover more code in less time. Make tests resilient, debug in record time, and spend less energy chasing bugs.
Launch faster
Refactor, upgrade, and roll out safely. Shift testing left, tighten feedback loops, and deploy with absolute confidence.
It’s hard to over-emphasize just how transformative this technology is for building distributed systems. For all intents and purposes, it really does feel like a time-traveler arrived from 20 years in the future and gave us their state of the art software testing technology.
Antithesis fits seamlessly into your existing development flow
Ensure reliability with property-based testing
Define key system behaviors once. Antithesis validates them continuously, so you don't have to update tests as code changes.

Discover critical bugs before your users do
Antithesis explores your system autonomously and uncovers complex, rare behaviors humans wouldn't think to test.

Streamline debugging with detailed artifacts
When you find a bug, Antithesis gives you clear visual diagnostics that show exactly what went wrong and where to look next.

Perfectly reproduce every bug found
Every failure in Antithesis is perfectly reproducible, thanks to full determinism and state capture. Say goodbye to flaky test reruns.
