relay.app: A self-hostable LLM environment you can configure in 2 minutes or less

Relay is a lightweight, self-hostable AI chat environment that connects to major LLM providers — including OpenAI, Anthropic, DeepSeek, and xAI — and can be set up in under two minutes. It supports MCP servers and lets users add custom tools to extend what the AI can do, like searching the web or running code. DeepSeek is highlighted as the best-value provider, with a 1M token context window costing roughly 14 cents.
