Avoid Atomic-Chat when you need cloud-based AI services that offer automatic updates and maintenance, as it focuses on local offline deployment. Do not choose this tool if your project does not require deep-seek capabilities or self-hosted solutions but prefers more mainstream LLMs like Qwen. ### When should I avoid ai-gateway? If your project only involves one or two LLMs which does not necessitate the gateway's broad compatibility features For small-scale projects that do not require comprehensive cost analysis tools When custom integration for specific guardrails is required, as ai-gateway offers generalized settings ### Is Atomic-Chat or ai-gateway more popular on GitHub? Atomic-Chat has more GitHub stars (1,363 vs 219). Stars measure visibility, not whether either tool fits your constraints. ### Are Atomic-Chat and ai-gateway open source? Yes - both are open-source projects on GitHub (Atomic-Chat: Other, ai-gateway: Apache-2.0). ### Where can I find alternatives to Atomic-Chat or ai-gateway? GraphCanon lists graph-backed alternatives at [Atomic-Chat alternatives](/tools/atomicbot-ai-atomic-chat/alternatives) and [ai-gateway alternatives](/tools/ferro-labs-ai-gateway/alternatives) ([Atomic-Chat markdown twin](/tools/atomicbot-ai-atomic-chat/alternatives.md), [ai-gateway markdown twin](/tools/ferro-labs-ai-gateway/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/atomicbot-ai-atomic-chat-vs-ferro-labs-ai-gateway.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, Atomic-Chat or ai-gateway? Atomic-Chat: Very active. ai-gateway: Very active. 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 Atomic-Chat and ai-gateway? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [Atomic-Chat trust report](/tools/atomicbot-ai-atomic-chat/trust); [ai-gateway trust report](/tools/ferro-labs-ai-gateway/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=atomicbot-ai-atomic-chat`](/api/graphcanon/graph?tool=atomicbot-ai-atomic-chat) - 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/_
