ThinkRail - (★ 1.6k at GitHub) is an agentic IDE from JetBrains, built around the pi coding agent.
An open-source JetBrains InnovationHub project. Every workspace is a real git worktree with its own branch, so you can run several agents in parallel without touching main. The project's intent lives in a graph of spec files that the agent reads and maintains. Monaco tabs, terminals and diffs are all in one window. Runs on macOS, Windows and Linux, as a desktop app or in the browser.
security-audit-skill - (★ 35.9k) is a coding-agent skill from Cloudflare for multi-phase security audits with independently verified, machine-readable findings.
It runs isolated agents through six phases: reconnaissance, coverage-led hunting, adversarial validation (the verifier is never the agent that found the bug), structured output, independent re-verification and reporting. This is the skill that seeded Cloudflare's own vulnerability discovery harness.
herdr - (★ 42.9k at GitHub) is a persistent terminal runtime for AI coding agents — keeps Claude Code, Codex, opencode and friends running even after you close the lid.
Another tool in the same space as Cezar we posted a few days ago. Where Cezar focuses on orchestrating agents across git worktrees with a dashboard, herdr is the session layer: agents live inside it like tmux panes, keep going when you disconnect, and you can attach the same session from any machine over SSH. It also reads each pane to tell you which agent is blocked and waiting on you.
Cezar - (★ 325 at GitHub) open-source orchestrator and ADE for running Claude Code, Codex, OpenCode and other AI coding agents in parallel — locally or on your own server.
Manages multiple agents via git worktrees, each in an isolated branch. Comes with a dashboard to monitor sessions, review diffs, and merge results. Self-hosted, no vendor lock-in.
Vorssaint - (★ 22.5k at GitHub) is a free, open-source macOS menu bar toolkit.
A modular Swiss Army knife for your Mac: keep-awake, per-app volume mixer, system monitor, app switcher, window manager, clipboard history, screenshot, uninstaller, and 40+ more utilities — install only what you need, uninstall and it vanishes completely.
OpenShell - (★ 10.5k at GitHub) is the safe, private runtime for autonomous AI agents.
Provides isolated sandbox environments where agents can execute shell commands, access tools, and run code — without touching the host system. Similar concept to Docker Sandboxes but purpose-built for AI agents, with fine-grained permission controls and audit trails.
Agentic Inbox - (★ 8.1k) a self-hosted email client with an AI agent, running entirely on Cloudflare Workers
Each mailbox lives in its own Durable Object (SQLite + R2), incoming mail routes via Cloudflare Email Routing, and an AI agent can read, search, and draft replies. MCP server at /mcp included — Claude Code, Cursor and friends can operate on your mailbox directly.
