About Antithesis
Antithesis is an autonomous, deterministic software testing platform. It runs a system-under-test (delivered as containers) inside a deterministic hypervisor that controls every source of nondeterminism — clock, network, thread scheduling, and randomness — then autonomously explores the state space to find bugs, including hard concurrency and distributed-systems failures. Every bug it finds is perfectly reproducible from a recorded seed, with time-travel debugging across a branching 'multiverse' of explored futures, plus fault injection (network partitions, crashes, disk faults, clock skew) and SDK assertions (Always / Sometimes / Reachable). [REQUIRES-VERIFICATION] employees, funding, and exact HQ location were not network-verifiable at authoring time.

| 01 | A property violation is reported. The operator needs to know what sequence of events led to it. | Read the triage report to follow the causal chain from setup through the events leading to the violated assertion, using the deterministic timeline rather than guessing from logs. The report exists to localize root cause; treat it as the primary debugging artifact and correlate assertion ids to cod… | Pass / FailAi Platformhigh |
| 02 | The operator wants to step through the failing process in a debugger at the moment the invariant broke. | Reproduce the failing run from its seed and step through with a debugger, using time-travel to reach the exact pre-failure state — the determinism guarantees the debugger sees the same execution every time.

| 03 | An operator wants to share a failing reproduction with a vendor, but the run captured request bodies containing customer PII. | Before sharing a reproduction or report externally, confirm it does not embed secrets or PII captured from the SUT (request bodies, tokens in logs); redact or use synthetic data in test workloads so reports are shareable. Treat run artifacts as potentially containing sensitive captured data. [REQUI… | Pass / FailAi Platformcritical |
