OmniRoute

OmniRoute sits between your AI coding tools and the actual model providers. Instead of configuring each tool separately for each provider, you run OmniRoute locally, point everything at one endpoint (localhost by default), and let the gateway handle the rest. It supports 260+ providers including many with free tiers, stacks them into priority chains called combos, and slides down the chain in milliseconds when a provider hits a rate limit or goes offline.

The token compression layer (RTK plus Caveman compression) claims 15-95% token savings on many request types, which matters when you're running heavy agentic workflows. Routing strategies go beyond simple round-robin: you can optimize for cost, for speed, for context relay across turns, or for strict provider order. The built-in MCP server exposes tools for agents to drive the gateway programmatically, and A2A protocol support lets other agents control routing decisions.

OmniRoute went viral on GitHub in mid-2026, growing to 23,000+ stars in weeks, largely because it solved a real pain point: builders running Claude Code or Cursor all day were burning through subscription quotas and hitting limits mid-session. The self-hosted, MIT-licensed design also appeals to teams that don't want prompts routed through a vendor's cloud router. It's the kind of tool that shows up in a Slack channel with 'just try this' and spreads from there.
