# ai-gateway vs afm-Server

*GraphCanon updated Sep 20, 2026*

## Verdict

Pick ai-gateway if ai-gateway from Ferro Labs supports over 30 LLMs with integrated caching, guardrails, A/B testing, and cost controls, making it ideal for managing multiple language models in a production environment; pick afm-Server if afm-Server provides macOS users with local access to Apple's on-device foundational AI models through an API compatible with OpenAI standards.

[ai-gateway](https://docs.ferrolabs.ai) reports 256 GitHub stars, 35 forks, and 68 open issues, last pushed Sep 10, 2026. [afm-Server](https://github.com/Techopolis-Online/Perspective-Intelligence) has 192 stars, 9 forks, and 2 open issues, last pushed Jun 2, 2026. Figures are from public GitHub metadata via [ai-gateway's repository](https://github.com/ferro-labs/ai-gateway) and [afm-Server's repository](https://github.com/Techopolis/afm-Server).

## Choose when

### Choose ai-gateway if…

- ai-gateway is primarily Go; afm-Server is Swift.
- License: ai-gateway is Apache-2.0, afm-Server 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

### Choose afm-Server if…

- afm-Server is primarily Swift; ai-gateway is Go.
- License: afm-Server is MIT, ai-gateway is Apache-2.0.
- Tags unique to afm-Server: apple-intelligence, foundation-models, local-llm, macos.
- When you need local, cloud-free inference services from Apple's device-based AI models and are working within a macOS environment

## When NOT to use 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

## When NOT to use afm-Server

- In scenarios where a cross-platform solution is necessary as afm-Server only supports macOS environments
- When your application demands real-time, high-throughput API access that can be limited by the device's hardware capabilities compared to cloud solutions
