OpenRouter Price Monitor

About this app

OpenRouter Price Monitor is the must-have companion for anyone who builds software with AI coding agents. If you use tools like OpenCode, Claude Code, GitHub Copilot, or Cursor and route your LLM traffic through OpenRouter, this app sits quietly in your macOS menu bar and keeps you informed about the true cost of every interaction — before the bill surprises you. Adding a new model to your agent's configuration? Before you commit, glance at the menu bar to see its current price, weighted cost score, context window, and capability set. Running an agent-heavy session? The credits dashboard shows exactly how much you are spending per API key, broken down by model, day, and week. You will spot expensive models eating your budget in seconds. **Comprehensive Model Dashboard** Browse the entire OpenRouter catalog — hundreds of models. At a glance, see input price, output price, context length, max output tokens, and knowledge cutoff date for each model. Powerful filters let you narrow the list by price tier (nine brackets from Free to $50+/M tokens), capability (agentic, image generation, text-to-audio, and more), or free-text search across names and descriptions. Sort by weighted price, input price, output price, context size, or cutoff date. Find the cheapest model that still supports tool use and structured output — in under five seconds. **Intelligent Weighted Price Score** Raw per-token prices only tell part of the story. OpenRouter Price Monitor computes a customizable Weighted Price Score that blends input price, output price, and cache read price using your own workload parameters. Adjust the input/output token ratio and estimated cache hit rate in Settings, and the score instantly re-ranks models to reflect your real cost profile. **Favorites & Desktop Notifications** Star the models you care about most — the ones configured in your agent workflows. The app polls OpenRouter on your schedule — every hour up to every eight hours — and compares prices against the previous snapshot. When a favorited model's price changes by more than your configured alert threshold (1%, 5%, 10%, or 20%), you receive a native macOS notification. You also get alerted when a model becomes newly free, so you are always the first to know about zero-cost options for your coding agent. **Full Price Change History** Every detected price change is logged with timestamps, old and new prices (input and output), and color-coded increases and decreases. The Price Changes Log tab gives you a complete audit trail of how model costs have shifted over time. **Spending Visibility with Management API** Connect a Management API key to unlock credit tracking and per-key usage analytics. The credits dashboard shows total purchased, used, and remaining balances with color-coded warnings when you are running low. Dive into individual API keys to see model-level spend, request counts, and token usage broken down by day or week — sortable by any column. **Latency Benchmarking** Run instant latency tests on any model and see the real time-to-first-token measured in milliseconds. Results are logged with green/yellow/red color coding and clear status messages for rate-limited or failed requests. Essential for evaluating whether a new model is fast enough for interactive agent use. **Privacy & Security First** No API key is required to monitor prices — the core experience works out of the box. When you optionally add an OpenRouter key for latency tests or a Management key for credit tracking, both are stored exclusively in the macOS Keychain using hardware-backed encryption. The Management key connection is further secured with certificate pinning to prevent man-in-the-middle attacks. Usage analytics and crash reporting are opt-out. OpenRouter Price Monitor is the essential companion for AI coding agent users. Stay informed, avoid surprise bills, and always know which model gives you the best value for your agent workflows.
