AI Agent Framework Comparison

This is a reference tool, not a numeric calculator, so the methodology is about how the data is sourced and how filtering is computed — both fully in your browser, with zero network requests at runtime.

1. Field definitions. Each capability column has a precise, documented meaning — for example, MCP / tools means the framework ships first-party support for the Model Context Protocol or a documented tool-calling abstraction. The exact definitions appear in the tooltip on each capability chip.
2. Tri-state cells. Every capability is Yes (documented first-party), Partial (community/experimental or via an add-on) or No (not documented). Each Yes and Partial links to the page that documents it.
3. License and language.The license is taken verbatim from each repository's LICENSE file / SPDX id. Only officially published SDK languages count toward the language column.
4. Filtering logic. Language and License chips are OR within their group — a framework matches if it offers any one of the selected languages or licenses. Capability chips are AND — a framework must support every selected capability, because if you require Memory and MCP you want frameworks that have both, not either. The three groups are AND-ed together, then an optional name search narrows further. In set terms a framework matches iff langOk && licenseOk && everyCapOk && nameOk.
5. No scoring, no winner.Results are shown in alphabetical order. The tool never emits a single "best" framework, because that would be opinion rather than a citable fact.

The filter predicate is implemented twice — a generic group loop and an independent Set-based re-derivation — and a self-check confirms the two agree on every framework for any query. This is the same cross-check discipline the site's calculators use, applied to boolean logic instead of arithmetic.

Each framework's own documentation is the authoritative source for its features; license and language facts come from the repository itself. Primary sources, one per framework:

• Microsoft AutoGen — docs
• CrewAI — docs
• Google ADK — docs
• LangGraph — docs
• LlamaIndex — docs
• OpenAI Agents SDK — docs
• PydanticAI — docs
• Semantic Kernel — docs
• Strands Agents — docs

Every cell on this page was last cross-checked against these sources on Jun 25, 2026. The dataset is re-verified on major framework releases. Spotted something out of date? Email me with a source link and I'll fix it.
