Reproduce a production bug on your laptop, no database required.

▤ Summary

Pure Effect introduces a zero-dependency effect library for JavaScript and TypeScript that keeps business logic pure and represents I/O as data. The product lets developers inspect, test, and replay workflows without touching a database or other infrastructure until an interpreter runs the effect tree. It includes primitives such as Success, Failure, Command, Ask, Retry, and Parallel to model request-shaped workflows. The launch also emphasizes easier debugging of production failures, structure-based testing, and cleaner AI-generated code audits. The product targets application developers who want deterministic control flow and simpler validation of side effects.
