[vllm-cli](https://github.com/Chen-zexi/vllm-cli) reports 506 GitHub stars, 29 forks, and 5 open issues, last pushed Jan 25, 2026. [ai-gateway](https://docs.ferrolabs.ai) has 219 stars, 33 forks, and 63 open issues, last pushed Aug 7, 2026.

See the comparison table for live GitHub stats and shared categories. ### When should I choose vllm-cli over ai-gateway? Choose vllm-cli over ai-gateway when vllm-cli is primarily Python; ai-gateway is Go; License: vllm-cli is MIT, ai-gateway is Apache-2.0; Tags unique to vllm-cli: llm, llm-inference, llm-tools, vllm; When you require an efficient and robust way to serve large language models through the command line using vLLM framework. ### When should I choose ai-gateway over vllm-cli? Choose ai-gateway over vllm-cli when ai-gateway is primarily Go; vllm-cli is Python; License: ai-gateway is Apache-2.0, vllm-cli is MIT; Tags unique to ai-gateway: ai-gateway, litellm, llm-cost, llm-proxy; Also covers Model Training; When you need to integrate more than 30 different LLM services including OpenAI and Anthropic. ### When should I avoid vllm-cli? If your project demands a graphical user interface or web-based interaction for model serving When ease of use with non-Python environments is a priority, as vllm-cli is designed specifically for Python users ### 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 vllm-cli or ai-gateway more popular on GitHub? vllm-cli has more GitHub stars (506 vs 219). Stars measure visibility, not whether either tool fits your constraints. ### Are vllm-cli and ai-gateway open source? Yes - both are open-source projects on GitHub (vllm-cli: MIT, ai-gateway: Apache-2.0). ### Where can I find alternatives to vllm-cli or ai-gateway? GraphCanon lists graph-backed alternatives at [vllm-cli alternatives](/tools/chen-zexi-vllm-cli/alternatives) and [ai-gateway alternatives](/tools/ferro-labs-ai-gateway/alternatives) ([vllm-cli markdown twin](/tools/chen-zexi-vllm-cli/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/chen-zexi-vllm-cli-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, vllm-cli or ai-gateway? vllm-cli: Slowing. 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 vllm-cli and ai-gateway? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [vllm-cli trust report](/tools/chen-zexi-vllm-cli/trust); [ai-gateway trust report](/tools/ferro-labs-ai-gateway/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=chen-zexi-vllm-cli`](/api/graphcanon/graph?tool=chen-zexi-vllm-cli) - 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/_
