HTTP Toolkit for MAC
Free, open-source HTTP debugger for Mac: intercept, inspect and edit HTTP(S) traffic from browsers, apps and terminals with one click.
HTTP Toolkit Overview
HTTP Toolkit is an open-source tool for debugging, testing and building with HTTP. It captures HTTP and HTTPS traffic with one-click interception for a wide range of tools: browser windows, Android or iOS apps, Docker containers, terminal sessions and backend processes such as Node.js, Java, Python or Ruby. You can target a single client instead of your whole computer, or connect any client to HTTP Toolkit as an HTTP proxy.
Explore traffic with filtering, look at the URL, status, headers and body of each message, with explanations of standard headers and formatting for JSON, Protobuf, Base64, HTML, XML and more. Breakpoints pause live traffic so you can edit it by hand, and a built-in HTTP client sends your own requests. These are in the free Hobbyist plan; the paid Pro plan adds automated mocking and rewriting and more. HTTP Toolkit is open source under the AGPL-3.0 license. It has separate downloads for Apple Silicon and Intel Macs and needs macOS 12 or later.

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
