# Microsoft Agent Framework

> Updated 2026-10-02 · type: tool · category: ai-infrastructure · status: active · rev 1

Microsoft Agent Framework is an open (MIT) runtime for building, orchestrating and deploying single and multi-agent AI workflows across both Python and .NET.

- Open source: yes (MIT)
- Self-hostable: yes
- Pricing model: free
- Best for: An engineering team building agents or multi-agent workflows that wants a maintained, MIT-licensed framework with real orchestration primitives and support for both Python and .NET — useful for .NET shops that most Python-first agent frameworks leave out.
- Not for: A non-engineering team that wants a no-code agent builder or a finished product; this is a developer framework you build on, not a turnkey app, and it is young and moving fast so expect API churn.

Microsoft Agent Framework is an open (MIT) framework for building, orchestrating, and deploying AI agents and multi-agent workflows, with first-class support for both Python and .NET. Open source: yes (MIT); self-hostable; free OSS. It has ~13.9k stars, ~3,400+ commits, is actively developed, and comes from the microsoft org.

## What it does

Agent Framework gives developers the primitives to build an agent and then compose several into a workflow: defining agents, wiring their tools, and orchestrating how they hand work between each other. The notable part is the dual runtime. Most agent frameworks are Python-first and leave .NET shops to improvise, while this one supports Python and .NET as first-class targets, which matters for the many GTM and enterprise systems that live in the .NET world. It is MIT-licensed and self-hostable, so you run it on your own infrastructure rather than inside a vendor's agent product. Open source: yes (MIT); self-hostable; free OSS.

## Provenance

- MIT per repo (license read from GitHub metadata, not guessed); ~13,910 stars; ~3,412 commits on main; from the microsoft org; active (pushed 2026-10-02) (github.com/microsoft/agent-framework, verified 2026-10-02).
- Repo description: "A framework for building, orchestrating and deploying AI agents and multi-agent workflows with support for Python and .NET."
- Surfaced in the GTM Stacker X/Twitter signal report (2026-10-02 pass); license/facts independently verified 2026-10-02.
- Specific orchestration capabilities are the project's own description (vendor-claim); not independently tested here.

## Why it matters for a GTM stack

If you are building agents into a GTM stack rather than buying one, the framework underneath is a long-lived decision, and this is a credible, permissively-licensed option with unusually strong .NET support. For a team whose CRM, billing, or internal tooling already runs on .NET, a framework that treats .NET as first-class (not a port) removes real friction, and MIT plus self-hosting keeps the agents and their data on your infrastructure. The honest read: it is a framework, not a finished agent, so there is build work and ongoing maintenance, and because it is young and fast-moving you should pin versions and expect churn. It is also a Microsoft project, so sanity-check whether a given integration path leans on Azure or Microsoft services before you assume it is neutral.
