What is tramli state machine?

Tramli is a multi-language flow engine that verifies state transitions and data dependencies at build time, preventing invalid flows in auth, orders, and sagas.

XState handles complex hierarchies; tramli prioritizes full data-flow proofs via flat states (with hierarchy plugin option). Use tramli for guaranteed data presence.

Does tramli work in Java, TypeScript, Rust?

Yes, identical APIs across all three, verified by shared tests.

⚡ Key Takeaways

Tramli verifies data flow across all paths at build time, killing runtime state bugs like missing OAuth codes. 𝕏
Flat states enable full path enumeration; trade hierarchy for proofs (plugins add it back). 𝕏
Multi-language support with plugins for real-world needs like idempotency and observability. 𝕏
