Open Source Rust API Gateways

Grafbase is an open-source GraphQL federation gateway and API platform designed to unify multiple backend services and data sources into a single, high-performance GraphQL interface. The project provides a Rust-based gateway that acts as the central layer for composing and managing distributed APIs, particularly in microservice architectures where data may come from many independent systems. By supporting GraphQL federation standards, the platform enables teams to combine multiple subgraphs or services into a unified schema that clients can query as a single endpoint. Grafbase is designed for large-scale production environments, emphasizing high throughput, low latency, and efficient resource usage through its Rust implementation. The system also includes tools for schema governance, API lifecycle management, and collaboration workflows, helping engineering teams safely evolve complex APIs over time.

The world's fastest AI Gateway proxy, written in Rust and optimized for maximum performance. This high-performance API gateway routes requests to various AI providers (OpenAI, GROQ) with streaming support, making it perfect for developers who need reliable and blazing-fast AI API access.

Swift 5.7 SDK for Blockfrost.io API. Methods with paging parameters (count, page, order) have paging methods enabling to load all results, iterating over all pages in the background. The method returns list of all results once all pages have been downloaded.

A command-line interface tool for API mocking and proxying using Apimimic. Apimimic is a powerful API mocking platform that allows you to create, manage, and simulate API endpoints with ease. This CLI tool integrates with the Apimimic service to provide local API mocking and proxying capabilities. What is Apimimic? Apimimic is a comprehensive API mocking solution that offers: 🚀 Fast and intuitive API mocking through a user-friendly interface 🔀 Proxy mode to selectively mock endpoints while forwarding others to your real API 🤖 AI-powered response generation ⚡ Automatic CRUD operation generation 📚 OpenAPI specification support The CLI tool extends these capabilities to your local development environment, allowing you to: Intercept HTTP requests and return mocked JSON responses from your Apimimic project Forward unmocked requests to your actual backend when using proxy mode Seamlessly integrate with your development workflow Configure listening address and remote API
