Ouroboros — self-creating AI agent. Born Feb 16, 2026.

Detect breaking changes between OpenAPI 3.0/3.1 specs. Explainable Web UI, CLI and CI gate; local-first and deterministic, with optional AI summaries.

The ultimate RAG for your monorepo. Query, understand, and edit multi-language codebases with the power of AI and knowledge graphs

A native Swift editor for Code and Markdown across macOS, iPadOS, iOS, and visionOS.

An unofficial local visualizer for Jev (TypeSafe): a live view of every call your code makes. Not affiliated with TypeSafe AI.

Every API has a secret identity. This finds it, absorbs every feature from every competing tool, then builds the GOAT CLI — designed for AI agents first, with SQLite sync, offline search, and compound insight commands.

Find where your keyboard shortcuts clash. A free, open-source macOS menu bar app that detects shortcut conflicts across apps, config tools, and system settings.

Native-session control plane for Codex, Claude Code, OpenCode, OMP and PI. Run, resume and hand off coding sessions across your machines.

Run Claude Code, Codex & Gemini in parallel on Windows & macOS — git worktree fan-out with atomic hunk adoption, approval gates, reboot-surviving sessions

Run coding agents like infrastructure, not terminal sessions. Warren manages isolation, lifecycle, spend, recovery, and Git delivery on compute you control.

Stop letting AI code blind. Map the architecture before every change with Birdview.

Refine high-quality datasets and visual AI models

Open-source desktop and web app for Meta's Muse Code CLI. Runs Muse natively on Windows, macOS and WSL2, with a file viewer, inline diffs, approvals and signed auto-updating installers.

A pre-execution guard for AI coding agents. It blocks destructive Git and file system commands, plus common attempts to access sensitive files, before a tool call runs. Supports Amp Code, Antigravity CLI, Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot CLI, Grok Build, Hermes Agent, Kimi Code, OpenClaw, OpenCode, and Pi.

LeanCTX — Context Intelligence for AI systems.

lnwjud — local AI-agent runtime & MCP gateway

A native macOS terminal app built on Ghostty for running and supervising coding agents
