State Management Python Packages

python-statemachine

Expressive statecharts and FSMs for modern Python.

honcho-ai

Memory library for building stateful agents

memori

Memori is agent-native memory infrastructure. A LLM-agnostic layer that turns agent execution and conversation into structured, persistent state for production systems. Built for enterprise, Memori works with the data infrastructure you already run, no rip-and-replace, and deploys across managed cloud, single-tenant cloud, VPC, and on-premises.

burr

Build applications that make decisions (chatbots, agents, simulations, etc...). Monitor, trace, persist, and execute on your own infrastructure.

vmx

Spec-driven, lifecycle-aware MVVM/ViewModel framework for C#, Python, TypeScript, and Swift. One language-neutral VMx spec, four full-parity flavors, shared reactive primitives, and 286 conformance scenarios.

reaktiv

Signals for Python - Reactive Declarative State Management Library for Python - automatic dependency tracking and reactive updates for your application state. Inspired by Angular Signals / SolidJS.

memorisdk

Memori is agent-native memory infrastructure. A LLM-agnostic layer that turns agent execution and conversation into structured, persistent state for production systems. Built for enterprise, Memori works with the data infrastructure you already run, no rip-and-replace, and deploys across managed cloud, single-tenant cloud, VPC, and on-premises.

apache-burr

Build applications that make decisions (chatbots, agents, simulations, etc...). Monitor, trace, persist, and execute on your own infrastructure.
