If your project does not fit an event-driven or actor-based architecture model When the complexity of setting up a supervision tree and managing actors exceeds the needs of your application ### When should I avoid langchaingo? - If your project strictly adheres to another programming language where other implementations of LangChain are available. - When your application requires heavy customization at the framework level that might not be directly supported within LangChainGo’s current implementation. ### Is ergo or langchaingo more popular on GitHub? langchaingo has more GitHub stars (9,670 vs 4,658). Stars measure visibility, not whether either tool fits your constraints. ### Are ergo and langchaingo open source? Yes - both are open-source projects on GitHub (ergo: MIT, langchaingo: MIT). ### Where can I find alternatives to ergo or langchaingo? GraphCanon lists graph-backed alternatives at [ergo alternatives](/tools/ergo-services-ergo/alternatives) and [langchaingo alternatives](/tools/tmc-langchaingo/alternatives) ([ergo markdown twin](/tools/ergo-services-ergo/alternatives.md), [langchaingo markdown twin](/tools/tmc-langchaingo/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/ergo-services-ergo-vs-tmc-langchaingo.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, ergo or langchaingo? ergo: Active. langchaingo: Slowing. 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 ergo and langchaingo? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [ergo trust report](/tools/ergo-services-ergo/trust); [langchaingo trust report](/tools/tmc-langchaingo/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=ergo-services-ergo`](/api/graphcanon/graph?tool=ergo-services-ergo) - 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/_
