What is Antithesis?

Antithesis tests complex distributed systems. It automates end-to-end system testing and finds the unknown unknowns that traditional testing methods miss.

Capabilities

Autonomously searches for problems in your software in a realistic simulation of your production environment.

Massively parallel simulation ensures maximum test coverage.

Chaos testing injects realistic production faults, such as network degradation, server/service outages, race conditions, and memory issues.

Perfect reproduction of every bug we find, for efficient debugging of even the most complex problems.

Benefits

Release with confidence: Antithesis finds the rare bugs, the kind that only appear in production, and cause outages or correctness errors.

Debug and fix quickly: Every problem we find can be perfectly reproduced, allowing for efficient debugging of even the most complex issues.

Free your best engineers: Find bugs early and avoid production issues, so your team can focus on creating value.

Why it’s better

Autonomous testing discovers the unknown unknowns in your code, so you won’t be taken down by edge cases you didn’t anticipate.

Deterministic simulation gives you perfect reproductions of even the gnarliest bugs,making debugging much easier.

Our property-based approach means more, and more durable coverage, with much less code. You’ll never need to update a broken test again.

Intelligent parallelization massively accelerates testing. Simulate years of production chaos in a matter of hours.
