9RouterAI Gateway

Developers who want one local endpoint for Claude Code, Codex, Cursor, Cline, Copilot, OpenCode, and other compatible tools, with provider fallback and a dashboard instead of manual endpoint switching.

Free planFree and open source under the MIT license; self-hosted through the npm package or source. The gateway has no subscription price, but connected providers, accounts, quotas, and their Terms of Service still determine the real cost and availability. Verify live limits before relying on a provider.Official sources

LiteLLMAI Gateway

Developers and platform teams who want a self-hosted, free AI gateway with granular spend control, virtual keys, and fallbacks — without per-token platform fees.
