[baml](https://boundaryml.com/explore) reports 9.2k GitHub stars, 492 forks, and 339 open issues, last pushed Sep 11, 2026. [agent-framework](https://aka.ms/agent-framework) has 14k stars, 2.3k forks, and 605 open issues, last pushed Sep 18, 2026.

See the comparison table for live GitHub stats and shared categories. ### When should I choose baml over agent-framework? Choose baml over agent-framework when baml is primarily Rust; agent-framework is Python; License: baml is Apache-2.0, agent-framework is MIT; Tags unique to baml: boundaryml, guardrails, llm, programming-language; When you need a language that keeps types consistent at runtime and avoids the use of generic 'any' types. ### When should I choose agent-framework over baml? Choose agent-framework over baml when agent-framework is primarily Python; baml is Rust; License: agent-framework is MIT, baml is Apache-2.0; Requirements: Python version 3.6 or newer is required for Python installations.; The .NET Core SDK must be installed for utilizing the .NET packages.; Tags unique to agent-framework: agent-framework, agentic-ai, agents, multi-agent; Choose agent-framework if your project requires support for both Python and .NET, allowing you to develop across different ecosystems. ### When should I avoid baml? If your project requires dynamic typing or runtime flexibility not constrained by strict type definitions. In cases preferring other language-specific concurrency models that BAML doesn't support, favoring a different approach to parallelism might be necessary. ### When should I avoid agent-framework? Avoid using the agent-framework if your team does not have proficiency in either Python or.NET, as this may cause difficulties in leveraging its features effectively. Do not opt for agent-framework if you only need lightweight support for AI agents without a comprehensive orchestration and deployment framework. ### Is baml or agent-framework more popular on GitHub? agent-framework has more GitHub stars (13,573 vs 9,165). Stars measure visibility, not whether either tool fits your constraints. ### Are baml and agent-framework open source? Yes - both are open-source projects on GitHub (baml: Apache-2.0, agent-framework: MIT). ### Where can I find alternatives to baml or agent-framework? GraphCanon lists graph-backed alternatives at [baml alternatives](/tools/boundaryml-baml/alternatives) and [agent-framework alternatives](/tools/microsoft-agent-framework/alternatives) ([baml markdown twin](/tools/boundaryml-baml/alternatives.md), [agent-framework markdown twin](/tools/microsoft-agent-framework/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/boundaryml-baml-vs-microsoft-agent-framework.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, baml or agent-framework? baml: Very active. agent-framework: Very active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for baml and agent-framework? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [baml trust report](/tools/boundaryml-baml/trust); [agent-framework trust report](/tools/microsoft-agent-framework/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=boundaryml-baml`](/api/graphcanon/graph?tool=boundaryml-baml) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
