See the comparison table for live GitHub stats and shared categories. ### When should I choose promptflow over agentflow? Choose promptflow over agentflow when Tags unique to promptflow: ai-application-development, chatgpt, llm, prompt-engineering; Also covers Developer Tools; When you require a comprehensive environment to manage the full lifecycle of LLM applications from ideation to deployment in Python. ### When should I choose agentflow over promptflow? Choose agentflow over promptflow when Tags unique to agentflow: json, large language models, python, workflow-management; Also covers AI Agents; When you need to rapidly prototype LLM workflows with minimal coding via JSON configs. ### When should I avoid promptflow? If your team prefers or requires tools that support languages other than Python, as Promptflow is exclusively focused on the Python ecosystem. In cases where a more fragmented toolset with specialized components for different development stages might be preferable to an integrated framework approach. ### When should I avoid agentflow? Avoid if requiring advanced customization that goes beyond basic JSON configurations Not suitable for scenarios needing real-time dynamic changes in workflow setup during execution ### Is promptflow or agentflow more popular on GitHub? promptflow has more GitHub stars (11,193 vs 320). Stars measure visibility, not whether either tool fits your constraints. ### Are promptflow and agentflow open source? Yes - both are open-source projects on GitHub (promptflow: MIT, agentflow: MIT). ### Where can I find alternatives to promptflow or agentflow? GraphCanon lists graph-backed alternatives at [promptflow alternatives](/tools/microsoft-promptflow/alternatives) and [agentflow alternatives](/tools/simonmesmith-agentflow/alternatives) ([promptflow markdown twin](/tools/microsoft-promptflow/alternatives.md), [agentflow markdown twin](/tools/simonmesmith-agentflow/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/microsoft-promptflow-vs-simonmesmith-agentflow.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, promptflow or agentflow? promptflow: Active. agentflow: Dormant. 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 promptflow and agentflow? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [promptflow trust report](/tools/microsoft-promptflow/trust); [agentflow trust report](/tools/simonmesmith-agentflow/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=microsoft-promptflow`](/api/graphcanon/graph?tool=microsoft-promptflow) - 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/_
