macOS developer tools

Beam

Frameworks & Dev Tools

Puts windows from one Mac onto another as native windows with real input, so agents and builds can keep running on a Mac mini or Studio while you work from your laptop; encrypted, direct over your own network, subscription or lifetime license.

Mac app that gives AI agents their own desktop workspace to work in apps that have no API, while you keep using your Mac; connect Claude Code or Codex over MCP. Formerly Mecum.

CoIsland

Frameworks & Dev Tools

Mac app that watches your engineering stack (GitHub Actions, Sentry and more), shows only what needs you and hands the work to Claude Code, Codex or Cursor; keys stay on your Mac, lifetime from $29.

Native macOS workspace for coordinating coding agents, formerly Twine: controlled workflows, visual traces and cross-agent memory, with roles filled by Codex, Claude Code, OpenCode, pi, Antigravity, OMP or Kiro CLI. Apple Silicon, macOS 26+, MIT-licensed.

Open-source (Apache-2.0) container runtime for Apple Silicon Macs, written from scratch in Rust and Swift: instead of wrapping Docker Engine or containerd it boots a Linux VM through Apple's Virtualization Framework and implements namespaces, cgroups v2 limits, OverlayFS, bridge networking and OCI image pulls itself, with run, exec, logs, ps and stats commands. Early-stage project.

Free Mac app written in Rust for running Claude Code, Codex and Pi side by side in one window, with GPU-rendered terminals, browsers and files, unlimited workspaces and no account required; Windows and Linux have a waitlist.

Rust terminal system monitor for Apple Silicon Macs showing CPU, GPU, power, clocks, temperatures and processes, without sudo or telemetry.

Siteprint

Frameworks & Dev Tools

Safari extension for Mac that measures any website's design (colours, type scale, spacing, corners and layout) and exports it as one exact prompt or DESIGN.md for Claude Code, Cursor or Codex; free to try, Pro $19.99 once.

Mac app and CLI that searches all your past coding-agent sessions before each prompt and hands your agent a short recollection with sources; works with Claude Code, Codex, Cursor, OpenCode, Amp and more, indexes locally, with shared team workspaces.

Native macOS terminal built on libghostty that your coding agents can control and extend: ask an agent to build custom panels, commands and layouts in HTML, CSS and JavaScript, and see which agent is working in each pane. Requires macOS 27 on Apple silicon.

Free, open-source (AGPL-3.0) native database client written in Swift, pitched as an open TablePlus: connects to 30+ SQL and NoSQL databases through native drivers, with built-in AI chat, inline suggestions and an MCP server for Cursor, Raycast or Claude Desktop (bring your own key or run Ollama). macOS and iOS/iPad; extras like iCloud Sync are paid, Linux version in development.

Open-source (MIT) native macOS menu-bar screen recorder and screenshot tool for PR-sized clips: record a window, screen or dragged area, trim, and export MP4 (H.264 or HEVC), WebM or GIF with a 'fit under N MB' option, or mark up screenshots with arrows, text, pixelation and crop. Everything stays local. Requires macOS 15; install from the DMG or Homebrew.

Activity Monitor alternative for Mac that groups processes by app, tracks coding agent sessions and AI usage limits, finds forgotten dev servers and exposes an MCP server; pay once, no subscription.

AI Editors & Agents

Talk to Cursor, Claude Code or Antigravity over any handheld two-way radio: local Whisper transcription on your Mac types the command, and neural TTS reads the answer back with VOX tones; one-time lifetime license, Apple Silicon.
