LangGraph: More actively maintained framework with similar multi-agent capabilities

Programming framework for multi-agent agentic AI
As of 29 August 2026, AutoGen is free to use. AutoGen is an open-source programming framework developed by Microsoft Research for building AI agents and enabling cooperation among multiple agents to solve complex tasks. Softwr lists it under AI. AutoGen is made by Microsoft Research, available on API, Windows.
Overview
AutoGen is an open-source framework from Microsoft Research for building multi-agent AI applications with flexible orchestration patterns. It provides multiple abstraction levels from high-level APIs for rapid prototyping to low-level components for advanced use cases, supporting both Python and .NET development. The framework features a modular, extensible architecture with pluggable components, asynchronous messaging between agents, and built-in observability through OpenTelemetry for enterprise-grade monitoring. Note: As of March 2026, AutoGen is in maintenance mode and will not receive new features. Microsoft recommends new projects use the Microsoft Agent Framework, which merges AutoGen's orchestration with Semantic Kernel's enterprise stability.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about AutoGen.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Softwr does not host reviews and shows no star rating for AutoGen, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
