--- title: "ai-gateway vs mlx-swift-chat" type: "comparison" canonical_url: "https://www.graphcanon.com/compare/ferro-labs-ai-gateway-vs-preternatural-explore-mlx-swift-chat" tools: ["ferro-labs-ai-gateway", "preternatural-explore-mlx-swift-chat"] --- # ai-gateway vs mlx-swift-chat *GraphCanon updated Aug 25, 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 mlx-swift-chat if mlx-swift-chat is a SwiftUI frontend for local LLM inference on iOS and macOS using Apple's MLX framework. [ai-gateway](https://docs.ferrolabs.ai) reports 219 GitHub stars, 33 forks, and 63 open issues, last pushed Aug 7, 2026. [mlx-swift-chat](https://github.com/preternatural-explore/mlx-swift-chat) has 436 stars, 27 forks, and 9 open issues, last pushed Oct 27, 2024.
