#state-machine

State machines, statecharts, and actors for complex logic

Expressive statecharts and FSMs for modern Python.

A Swift and Kotlin library for making composable state machines, and UIs driven by those state machines.

write beautiful state charts :scream_cat:

Production-grade framework for building multi-agent AI systems. Graph-based orchestration, LLM-agnostic (OpenAI, Google GenAI, Anthropic), 3-layer memory (Redis cache + Postgres + vector store), live agents, parallel tool execution, and native MCP. Ships a full ecosystem: backend, REST API + CLI, TypeScript SDK, and React playground

Fast, easy Javascript finite state machines with visualizations; enjoy a one liner FSM instead of pages. MIT; Typescripted; 100% test coverage. Implements the FSL language.

The type-safe, event-driven workflow orchestration library that scales with your business. Build robust, distributed workflows in Go with compile-time safety, automatic retries, and horizontal scaling out of the box. Integrate with your existing tech stack using adapters 🚀

Hypothesis-like property testing for Rust

A Rust UI framework built on WASI.

A declarative language for LLM-driven state machines - the .mkl document is the program, an LLM is the runtime

A real router. Just routing, nothing else.

Production ready event-driven automata for Scala, Scala.js and scala native

The transparent, composable harness for TypeScript agents. The same code runs the full agent loop on a local 4B model or a frontier API, with tool-call healing, verification, and a signed evidence receipt for every run.

The extension for building state machines with Ash resources.

A unified, modular framework for AI-driven UI observation, control, and debugging.

Modern circuit breaker for Ruby & Rails. Thread-safe, fiber-ready async support. Built-in fallbacks, rich introspection, clean DSL. Memory-efficient with jitter & monitoring.
