CodeRouter — Cut Cursor, Claude Code & Aider API Bills by 70-90%

Phase-aware LLM routing reduces token costs for AI coding agents by automatically sending each request to the cheapest model proven capable of the work at hand. CodeRouter inspects the last user message, recent tool-call history, and agent fingerprinting to decide whether a prompt belongs to planning, implementation, debugging, testing, documenting, formatting, or restructuring. Within ten milliseconds it forwards the call to DeepSeek V3, Sonnet 4.6, Haiku, or Gemini Flash instead of defaulting to the higher-priced Opus tier for every task. The workflow requires one config change: point the coding agent’s base_url to the CodeRouter endpoint. Clients continue using Cursor, Aider, Claude Code, Copilot, Windsurf, OpenClaw, or any other OpenAI-compatible agent without writing new code. Each response includes headers that reveal the chosen model, the routing rationale, and exact cost, turning the pipeline into an inspectable log. Agents that normally burn through $15 or $75 per million tokens on Claude’s premium tier can cut bills by the amount recorded in the dashboard, which displays weekly savings derived from the user’s actual workload. On high-confidence phase detection the router completes an inexpensive, quality-matched substitution; on low-confidence requests it upgrades to a safer tier-one model rather than risk a poor result. Developers bring their own Anthropic or OpenAI keys or use the provider keys bundled with CodeRouter. Weekly AI cost-optimization tips are delivered by the service, and more than two thousand developers are already connected. Access is organized into three tiers based on token allowance and included Opus credits. The smallest plan supplies 5 million tokens plus 100 000 Opus tokens, capped at a $60 monthly limit. The mid-tier offers 30 million tokens plus 500 000 Opus, capped at $200. The largest tier reaches 80 million tokens and 1 million Opus, capped at $600, adds priority Opus routing and agent-fingerprint analytics, and supports up to 50 API keys under a shared dashboard. All plans carry a 15 % overage markup above the provider list price up to the stated cap, and nothing beyond that.
