Orvion
Orvion is a multi-provider LLM gateway built with Go and Gin, offering unified API access, a built-in WebUI, and observability.
Tool overview
Orvion addresses the challenge of managing multiple LLM providers through a single unified interface. Instead of writing separate integration code and monitoring for each provider, teams can route all requests through one gateway.
Its core workflow provides standard endpoints (/v1/chat/completions, /v1/embeddings, /v1/rerank, etc.), with the ability to bind one logical model to multiple upstream providers using weighted load balancing. The built-in WebUI covers provider configuration, API key management, request logging, and health monitoring, plus circuit breaker auto-recovery and per-key rate limiting (RPM).
Strengths include broad protocol compatibility (OpenAI/Anthropic format), lightweight deployment as a single Go binary, a built-in management dashboard, and Telegram alerting. The main caveats are its early-stage maturity (15 GitHub stars), small community, and in-memory rate limiting that limits multi-instance distributed deployment.
It fits small teams and solo developers managing multiple LLM providers, and is less suitable for large-scale production environments requiring persistent rate limiting and high-availability clustering.
