See the comparison table for live GitHub stats and shared categories. ### When should I choose langgraph4j over agentflow? Choose langgraph4j over agentflow when langgraph4j is primarily Java; agentflow is Python; Pricing: Available at no cost; commercial support and enterprise options may incur additional charges.; Requirements: Min 1 GB RAM; Tags unique to langgraph4j: agents, ai, langchain4j, spring-ai; When you are building an application in the Java ecosystem that requires integration with both Langchain4j and Spring AI. ### When should I choose agentflow over langgraph4j? Choose agentflow over langgraph4j when agentflow is primarily Python; langgraph4j is Java; Tags unique to agentflow: json, large-language-models, python, workflow-management; Also covers LLM Frameworks; When you need to rapidly prototype LLM workflows with minimal coding via JSON configs. ### When should I avoid langgraph4j? Avoid using it if your project strictly limits external dependency versions and necessitates an older version of Java (prior to 17), as LangGraph4j demands at least Java 17. If you require the absolute latest features before official release, direct snapshot use might pose instability risks that could disrupt development cycles or production environments. ### 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 langgraph4j or agentflow more popular on GitHub? langgraph4j has more GitHub stars (2,006 vs 320). Stars measure visibility, not whether either tool fits your constraints. ### Are langgraph4j and agentflow open source? Yes - both are open-source projects on GitHub (langgraph4j: MIT, agentflow: MIT). ### Where can I find alternatives to langgraph4j or agentflow? GraphCanon lists graph-backed alternatives at [langgraph4j alternatives](/tools/langgraph4j-langgraph4j/alternatives) and [agentflow alternatives](/tools/simonmesmith-agentflow/alternatives) ([langgraph4j markdown twin](/tools/langgraph4j-langgraph4j/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/langgraph4j-langgraph4j-vs-simonmesmith-agentflow.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, langgraph4j or agentflow? langgraph4j: Very 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 langgraph4j and agentflow? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [langgraph4j trust report](/tools/langgraph4j-langgraph4j/trust); [agentflow trust report](/tools/simonmesmith-agentflow/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=langgraph4j-langgraph4j`](/api/graphcanon/graph?tool=langgraph4j-langgraph4j) - 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/_
