Insomnia for MAC
Free, open-source API client for Mac: send REST, GraphQL, gRPC, WebSocket and SSE requests, design OpenAPI specs, run tests and mock APIs.
Insomnia Overview
Insomnia is an open-source API client for REST, GraphQL, WebSockets, Server-Sent Events (SSE), gRPC and other HTTP-based protocols. You use it to send requests and debug responses, design APIs in a built-in OpenAPI editor with a visual preview, test them with test suites and a collection runner, and mock them with a cloud or self-hosted mock server. The Inso CLI brings linting and tests into CI/CD pipelines, and plugins add more features.
Insomnia is made by Kong Inc. and the app is open source under the Apache 2.0 license. It is freemium: the local Scratch Pad works without an account, while most features need a free account. The free Essentials plan includes unlimited local and cloud projects, unlimited collection runs, end-to-end encryption and 1,000 mock server requests a month, with Git Sync projects for up to 3 users; paid Pro and Enterprise plans add unlimited collaboration, organizations, role-based access and single sign-on. Your projects are stored where you choose: Local Vault keeps everything on your Mac, Git Sync uses your own Git repository and Cloud Sync uses Kong's cloud. Version 13.4.0 is a bug-fix release. The Mac app is a universal app for Apple Silicon and Intel 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
