Self-hosted API rate gateway, queue system & proxy router with Admin UI in Go
RateGate is a high-performance, self-hosted API Rate Gateway built with Go 1.22+ and Redis. It sits in front of any third-party or internal API (OpenAI, Anthropic, Custom LLMs, Webhooks) to manage rate limits, client authentication, automatic retries, and usage tracking. Key Features: • Dual Mode: In-memory mode for single-instance setups, or Redis for distributed deployments. • Fine-Grained Limiting: Set RPS, Burst, and Daily quotas per API Key and per Upstream service. • Embedded Admin UI: Clean management dashboard compiled directly into the single Go binary. • Smart Queue & Retries: Automatic retries with exponential backoff on HTTP 429 and 50x errors. • Key Cloaking: Protect provider API keys by injecting them gateway-side. • Production Ready: Docker Compose setup, Prometheus metrics (/metrics), and zero-loss usage persistence. Tech Stack: Go 1.22+, Redis, Docker, Embedded Web UI, Prometheus, YAML Configs. What's Included: • Complete Go source code & project structure. • Dockerfile + docker-compose.yml for instant deployment. • Embedded Admin Panel UI. • Cross-platform build scripts (Bash/PowerShell). • Full documentation & commercial license template.
