--- title: "prompttools vs autogen" type: "comparison" canonical_url: "https://www.graphcanon.com/compare/hegelai-prompttools-vs-microsoft-autogen" tools: ["hegelai-prompttools", "microsoft-autogen"] --- # prompttools vs autogen *GraphCanon updated Jul 12, 2026* ## Verdict Pick prompttools if prompttools aims to support developers in the testing and experimentation of prompts for language models as well as integrating vector databases through Python utilities; pick autogen if autoGen is a Python-based framework for developing and managing agentic AI systems. It includes the AutoGen Studio for no-code GUI setup, integrating with various models. [prompttools](http://prompttools.readthedocs.io) reports 3.0k GitHub stars, 255 forks, and 41 open issues, last pushed Feb 11, 2026. [autogen](https://microsoft.github.io/autogen/) has 60k stars, 9.0k forks, and 945 open issues, last pushed Apr 15, 2026.

It includes the AutoGen Studio for no-code GUI setup, integrating with various models. ## Choose when ### Choose prompttools if… - License: prompttools is Apache-2.0, autogen is CC-BY-4.0. - Pricing: PromptsTools is open-source under the Apache-2.0 license, making it free to use but with no official support available.. - Tags unique to prompttools: llms, embeddings, deep-learning, machine-learning. - Also covers Vector Databases, Developer Tools. - Prompttools aims to support developers in the testing and experimentation of prompts for language models as well as integrating vector databases through Python utilities. ### Choose autogen if… - License: autogen is CC-BY-4.0, prompttools is Apache-2.0. - Requirements: Min 4 GB RAM; AutoGen requires Python 3.10 or later.; Ensure security when connecting to MCP servers due to the potential for local command execution and sensitive information exposure.. - Tags unique to autogen: llm-framework, autogen, agents, ai. - Also covers AI Agents. - You need a framework that supports integration with multiple AI models via OpenAI's chat completion client. ## When NOT to use prompttools - Last GitHub push was 151 days ago (slowing maintenance, Feb 11, 2026). Validate activity before betting a new project on prompttools. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ## When NOT to use autogen - If you require tools supporting multiple programming languages beyond Python, as AutoGen is strictly a Python-based framework. - When deploying in environments where connecting to external servers (like those used by MCP) could pose security risks or is prohibited. - You need solutions which do not involve additional installations for server components such as `playwright/mcp`, as AutoGen requires this setup for certain functionalities. ## Common questions ### What is the difference between prompttools and autogen? prompttools: Open-source tools for prompt testing and experimentation. autogen: A programming framework for agentic AI. See the comparison table for live GitHub stats and shared categories. ### When should I choose prompttools over autogen? Choose prompttools over autogen when License: prompttools is Apache-2.0, autogen is CC-BY-4.0; Pricing: PromptsTools is open-source under the Apache-2.0 license, making it free to use but with no official support available.; Tags unique to prompttools: llms, embeddings, deep-learning, machine-learning; Also covers Vector Databases, Developer Tools; Prompttools aims to support developers in the testing and experimentation of prompts for language models as well as integrating vector databases through Python utilities. ### When should I choose autogen over prompttools? Choose autogen over prompttools when License: autogen is CC-BY-4.0, prompttools is Apache-2.0; Requirements: Min 4 GB RAM; AutoGen requires Python 3.10 or later.; Ensure security when connecting to MCP servers due to the potential for local command execution and sensitive information exposure.; Tags unique to autogen: llm-framework, autogen, agents, ai; Also covers AI Agents; You need a framework that supports integration with multiple AI models via OpenAI's chat completion client. ### When should I avoid prompttools? Last GitHub push was 151 days ago (slowing maintenance, Feb 11, 2026). Validate activity before betting a new project on prompttools. LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ### When should I avoid autogen? If you require tools supporting multiple programming languages beyond Python, as AutoGen is strictly a Python-based framework. When deploying in environments where connecting to external servers (like those used by MCP) could pose security risks or is prohibited. You need solutions which do not involve additional installations for server components such as `playwright/mcp`, as AutoGen requires this setup for certain functionalities. ### Is prompttools or autogen more popular on GitHub? autogen has more GitHub stars (59,658 vs 3,041). Stars measure visibility, not whether either tool fits your constraints. ### Are prompttools and autogen open source? Yes - both are open-source projects on GitHub (prompttools: Apache-2.0, autogen: CC-BY-4.0). ### Where can I find alternatives to prompttools or autogen? GraphCanon lists graph-backed alternatives at [prompttools alternatives](/tools/hegelai-prompttools/alternatives) and [autogen alternatives](/tools/microsoft-autogen/alternatives) ([prompttools markdown twin](/tools/hegelai-prompttools/alternatives.md), [autogen markdown twin](/tools/microsoft-autogen/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/hegelai-prompttools-vs-microsoft-autogen.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, prompttools or autogen? prompttools: Slowing. autogen: Steady. 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 prompttools and autogen? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [prompttools trust report](/tools/hegelai-prompttools/trust); [autogen trust report](/tools/microsoft-autogen/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=hegelai-prompttools`](/api/graphcanon/graph?tool=hegelai-prompttools) - 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/_
