Throttle

Throttle is a macOS menu bar application built specifically for developers who rely on Claude Code as their primary coding assistant. It monitors your Claude usage in real time, displaying both your five hour and weekly limits directly in the menu bar where you can glance at them without switching context. The application predicts when you'll hit rate caps, giving you roughly two hours of warning before lockouts occur. Everything runs locally on your machine with no telemetry, no account requirements, and no data leaving your computer. For developers who've experienced the frustration of hitting Claude's limits mid-task, losing momentum on a complex refactoring or debugging session, Throttle provides the visibility needed to pace your work strategically and avoid those unexpected interruptions that derail productive coding sessions.

The core functionality centers on usage tracking and prediction with a level of detail that Claude's own interface doesn't provide. When you're signed into Claude Code, Throttle shows exact usage numbers pulled from your account. When you're not signed in, it provides reliable estimates based on your activity patterns and historical consumption. A countdown timer shows precisely when your limits will reset, removing the guesswork about whether you have enough headroom for another large task. The predictive nudge feature alerts you well before you approach your cap, typically around two hours out. This proactive approach means you can wrap up your current task, commit your changes, or switch to a different workflow before hitting the wall. You're never caught off guard during critical work, and you can plan your most token-intensive tasks around your reset schedule.

The Pro version expands into multi-session management, which becomes essential for developers juggling multiple Claude Code instances or working across several complex projects simultaneously. It offers a mission control style overview of all your active sessions, with tab-based navigation between them that makes switching contexts fast and organized. A memory pressure gate monitors your system and prevents saturation when running multiple instances, automatically throttling sessions before they impact your machine's performance. Auto-hibernation kicks in for idle sessions, conserving both system resources and your rate limit allocation. Session consolidation and duplicate merging help keep things organized when similar conversations accumulate over a workday. Rate limit awareness per session ensures no single project consumes your entire allocation unexpectedly, letting you distribute your usage intentionally across workstreams.

Token optimization tools embedded in Throttle help you extract more value from your usage limits over time. Output style presets let you choose between normal Claude responses and compressed modes like Concise or Caveman that reduce token consumption by requesting shorter, denser replies. Command output compression strips ANSI codes, escape sequences, and unnecessary formatting before sending terminal output to Claude, reducing the token cost of debugging and command-line workflows. The context trimmer identifies and removes re-charged base64 images that would otherwise inflate your usage when Claude re-processes visual content it's already seen. Local OCR converts screenshots to text before sending them to Claude, dramatically reducing the token cost of sharing visual content while preserving the information you need to convey. These optimizations compound over days and weeks, potentially extending how much work you accomplish within the same rate limits by a meaningful margin.

System integration features connect Throttle with your broader Claude Code environment and development workflow. It manages MCP (Model Context Protocol) servers, handling global configurations, project-local settings, and .mcp.json files with a unified interface. Settings.json hardening shows reviewable diffs before applying any changes, so you understand exactly what's being modified in your configuration. A searchable session history with semantic indexing lets you find past conversations, solutions, and code snippets across your entire Claude Code history, turning your accumulated interactions into a searchable knowledge base. The autopilot feature automates routine optimization decisions based on your preferences and usage patterns. Session offloading lets you move sessions to personal servers when you need to free up local resources or continue work seamlessly across machines, maintaining conversation context wherever you're working.

Throttle runs on macOS 14 and later, supporting both Apple Silicon and Intel processors with native performance. The application weighs 13.4 MB, installs without complex dependencies, and auto-updates via Sparkle so you always have the latest features and compatibility fixes. All data stays in your local ~/.claude directory, maintaining complete privacy. The application is signed and notarized by Apple, so it installs cleanly without security warnings. The free version includes the menu bar meter, predictive nudge, and single session cockpit, giving you essential visibility at no cost. The Pro version costs 29 euros as a one-time purchase with no subscription, unlocking multi-session management, autopilot, history and projections, and server offloading. For teams standardizing on Claude Code, Throttle supports policy export for MDM deployment, making it straightforward to roll out consistent configurations and usage guidelines across an organization.
