Claude Code Tools
Claude Code does the work in your terminal. These are the tools people put around it to run more of it at once, keep it safe, give it memory and feed it better instructions. Each one works with Claude Code, and most also run with Codex or Cursor. 20 tools listed.
Run Sessions in Parallel
Terminals and desktop apps for running more than one agent at a time, usually in separate Git worktrees.
Farol
Free open-source macOS terminal for running Claude Code and Codex in parallel with status sidebar and git worktrees.
pi-cowboy
Open-source (MIT) multi-agent orchestrator for the Pi coding agent that runs Pi, Claude Code, Codex or OpenCode as parallel subagents in isolated copy-on-write Git worktrees inside Herdr panes.
Twine
Native macOS agentic development environment for coordinating coding agents with controlled workflows, visual traces and cross-agent memory; drives harnesses such as Codex, Claude Code, OpenCode, pi and Antigravity. Apple Silicon, macOS 26+, MIT-licensed.
CoIsland
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.
Keep It Safe
Sandboxes, budgets, diff scanning and push checks for when Claude Code runs with less supervision.
SIwithin
Runs Claude Code or OpenAI Codex CLI unattended on a brief, fenced to the folders you give it and under a per-run dollar budget enforced by a loopback API proxy, leaving one ledger line per run. Single Python file, standard library only, macOS only, Apache-2.0.
Lights-on Software Factory
Open-source (MIT) boilerplate for running Claude Code as a software factory: a sandboxed container, a deterministic bash-command regulator, lint hooks for custom rules and a multi-agent workflow generator.
CybeDefend
Security and business rules for AI coding agents: one command installs VibeDefend into Claude Code, Cursor, Copilot or Codex to scan each diff and block risky actions, with SAST, SCA, secrets and IaC scanning; free plan.
Sphinx
Free, MIT-licensed Git hook that quizzes you on what your coding agent's diff actually does before a push to protected branches goes through; works with Claude Code, Codex, Cursor or plain Git.
Context and Memory
Stop losing what a session learned: handoff notes, searchable history and shared scratchpads.
catnap
Claude Code plugin that warns Claude at 50% context so it finishes its current piece, writes itself a handoff note and compacts at a clean break instead of mid-task. MIT-licensed.
Skillsync
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.
agent-archive
CLI to archive Claude Code, Codex and Cursor sessions to your own S3 or R2 bucket and hand a session's context off between agents or machines, plus browse history by topic, project, branch or PR. MIT-licensed, written in Go.
DocuMemory
Memory engine for AI-first engineers: distils Claude Code, ChatGPT and Cursor sessions into architecture decisions and prompt-injectable context blocks, recalled over MCP.
Jotbus
End-to-end encrypted shared scratchpad that lets Claude Code, Codex, Cursor, Gemini and other coding agents share notes and files, hand off work and review changes across machines; try it with npx jotbus.
Sharper Prompts and Checks
Point at the exact element, plan out loud, copy a design or let the agent verify its own work.
Spotnote
Open-source (MIT) Vite plugin: click any element in your running app, type what should change, and get a prompt with the exact source file, line and column to paste into Claude Code, Cursor or Codex; local-only and dev-mode only.
Luke
Open-source (Apache-2.0) Mac app for planning a feature out loud: Luke reads your code while you talk and writes a plan you can paste into Claude Code or Codex.
Siteprint
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.
Reticle
AI app testing that runs inside your app: it walks a flow like a user and reads network calls, app state and the console so your coding agent can verify its own work; free open-source SDK for Claude Code, Cursor and any MCP agent.
Costs and Team Visibility
Track token spend per message, cap spend at the gateway and share tools across a team.
Opaline
Team-wide, message-level analytics for Claude Code and Codex sessions: token cost, time and skill usage for every message across your team; open-source CLI, paid team plans.
Opper
EU-hosted AI gateway: 700+ models behind one OpenAI-compatible API, pay-as-you-go, with spend caps, model allowlists and zero data retention; works with Claude Code, OpenCode and Cursor.
CoreSpeed
One MCP endpoint that gives Claude Code, Codex or Cursor your apps, your team's shared memory and built-in tools, with spend caps, approvals and an activity log; free plan, Pro $20/month.
