UnicodeChecker for MAC
Free Mac app to explore and convert Unicode: details for every code point, Unihan data, and conversions to HTML, CSS, URLs and code.
UnicodeChecker Overview
UnicodeChecker is a free Mac app for exploring and converting Unicode. For every code point it shows the Unicode number and its UTF encodings, related code points and decomposition. You can browse by plane, code point number or character block, find code points by name or by their Unihan definition, and even find them through Spotlight. For many Asian code points it shows Unihan data such as definitions, variants, pronunciations and older encodings.
Its conversion tools turn text to and from HTML, CSS, URLs, IDNA and various programming languages, and check Unicode normalisation (NFC, NFKC, NFD and NFKD). Split Up and Diff analyse a string code point by code point and highlight differences, and most features work in any app through the Services menu and AppleScript. UnicodeChecker is freeware by earthlingsoft (Steffen Kamp and Sven-S. Porst); donations are welcome. It uses data from Unicode 17.0.0. Version 1.25.1 fixes the Diff utility. It is a universal app for Apple Silicon and Intel and needs macOS 10.13 or later; older versions for earlier systems are on the developer's site.

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
