rayline.ai/ →Not every Claude Code subagent needs a frontier model
WHAT IT SOLVES
AI coding agents burn tokens fast, but subtasks vary wildly in how much intelligence they actually need
WHY IT'S INTERESTING
Route inside the agent, not at the user level
Claude Code spawns subagents constantly. Rayline intercepts at this layer — simple tasks get routed to local or cheap models, only the hard ones hit frontier. 60–90% token savings isn't marketing; it's what the architecture naturally enables
Open-source local router + hosted gateway, shipping both
Rayline Local is open-source, runs on your Mac with on-device models. Rayline Cloud is a hosted gateway — one endpoint, every major model provider. They claim billions of tokens routed daily. This is infra, not a weekend project
「Routes Claude Code subagents to on-device and cheaper models」
TECH GUESS
Likely Go or Rust routing layer, local side probably uses MLX/Ollama for on-device inference, cloud side is an API gateway
