About Flawless

Flawless is an execution engine for durable computation that runs code to completion even in the presence of hardware or software failures. It enables developers to model persistent application state with just code and local variables, while ensuring continuous persistence for modern user experiences. The engine compiles Rust workflows to WebAssembly and executes them in a deterministic environment, using a log of non-deterministic side effects to replay work after interruptions. Flawless aims to help builders create complex, stateful experiences by automating reliable workflow continuation across restarts.
