Reactotron for MAC
Free, open-source desktop debugger for React and React Native apps: inspect state, API requests, logs, errors and performance on your Mac.
Reactotron Overview
Reactotron is a free, open-source desktop app for debugging React and React Native applications. It gives you an easy-to-use window for monitoring your app's state, network requests and performance, and it suits projects of any size, from small personal apps to large enterprise ones. You add it to your project as a dev dependency, so it adds nothing to your production builds. Setup guides for React and React Native are in the official documentation.
Reactotron is made by Infinite Red, which uses it every day to build client apps, and it is released under the MIT licence. The Mac version comes as separate downloads for Apple Silicon and Intel, and the Apple Silicon app states macOS 10.15 or later as its minimum. Version 3.11.0 adds redaction filtering for sensitive data to the app's MCP server, the connection that was added in version 3.9.0 for Claude Code integration. Plugins cover Redux, MobX-State-Tree, Async Storage, MMKV, networking and more. Reactotron is a tool for developers and needs a React or React Native project to connect to.

- API monitoring: see API requests and responses.
- Logging: display messages similar to console.log.
- Error tracking: global errors with source-mapped stack traces.
- Benchmarks: run quick performance benchmarks.
- State control: dispatch actions and hot swap state with Redux or MobX-State-Tree.

OrbStackOrbStack is a fast, light and simple way to run Docker containers and Linux machines on your Mac. It is a drop-in replacement for Docker Desktop: your docker and docker compose commands keep working, and on first start OrbStack offers to copy over your existing Docker Desktop containers, images and volumes. It starts in seconds, uses less than 0.1% background CPU on Apple Silicon and returns unused memory to macOS. Besides containers it runs full Linux machines from 16 distributions, and a lightweight Kubernetes cluster for local development. OrbStack is made by Orbital Labs.Developer Tools
QuotaBarIf you use OpenAI Codex with a ChatGPT account, the usage limits reset on a 5-hour and a weekly window, and checking how much is left means opening Codex or ChatGPT. QuotaBar puts the remaining percentage in the Mac menu bar and refreshes it every 60 seconds. Click the icon for a detailed panel with every limit window and its reset countdown, or turn on a small floating HUD that stays on top of other windows.Developer Tools
Stargazer BarStargazer Bar is a small native menu bar app for Mac that keeps an eye on GitHub repositories for you. It puts a live star count in the menu bar, so you can see how a project is doing without keeping a browser tab open, and a click opens a dropdown with the details: star and fork trend charts, release download totals and a maintainer radar. Public repositories are measured by their stars. Private repositories, which have no stars, are measured by what needs your attention: a failing build, an unanswered issue or a new pull request.Developer Tools
Notch So GoodNotch So Good turns the notch of your MacBook into a small status display for AI coding agents. While Claude Code or the OpenAI Codex CLI works, a black pill extends the notch: a 3D character called Peek sits on the left, and a ring on the right shows how much of your 5-hour usage window is left. The more a session needs you, the further Peek climbs out. When a task finishes, fails or runs into a usage limit, the notch opens into a card that says what happened and in which project, and a click jumps to the exact terminal tab, tmux pane included.Developer Tools
Claude UsageClaude Usage is a small native app for people who use Claude Code. In the menu bar it shows your current five-hour session, your weekly usage for all models and for Sonnet, and your pay-as-you-go credits, each with a usage bar and its reset time, without opening Claude Code. It also adds a one-line readout under your Claude Code prompt with the model, how full the context window is and the tokens used, so you can compact a session before it runs out of room. Each terminal pane shows its own readout, also across tmux.Developer Tools
TintpadTintpad is a free, open-source launcher for developers who work with command-line coding agents such as Claude Code and Codex. Press Option-Command-Space anywhere and a black drop falls out of your Mac's notch, or hangs below the menu bar on Macs without one, with your repositories inside. Type a few letters, press Return, and your own terminal opens at that repository with the agent already running, in the mode you used there last.Developer Tools
