your whole tailnet, on one page.
Bield is a self-hosted control plane for the machines on your tailnet. It's one binary. Run it on a server, and it joins your Tailscale tailnet (or a Headscale one) and shows every machine in one place: how healthy it is, what's wrong with it, what runs on it. From the same page, you can open a terminal on it, browse its files and restart its containers. There's no password and no account to make, because your tailnet is the login.

Auto Ontology is a Python framework for building semantic, graph-based reasoning layers over data. It enables deterministic query generation, better context retrieval, and more explainable AI for LLM and agent workflows.
Agents can retrieve documents and query databases, but reliability gates agentic analytics: a revenue metric answered faster is worth nothing if the number is wrong. Agents need a context layer that tells them where data lives, what it means, whether to use it, how to use it, where it came from, and what is similar. NVIDIA Auto Ontology is an open library that builds that layer from enterprise metadata, reconciles definitions across systems, and exposes it to any agent harness through MCP, CLI, and API. It complements the semantic models customers already own.
Browser Automation for AI.
Browser automation CLI designed for AI agents. Compact text output minimizes context usage. 100% native Rust.
A command line interface wallet for moving funds between public Ethereum accounts (derived from your seed) and private balances on Tornado Cash, Railgun and Privacy Pools (V1) -- whose credentials also conveniently live on the wallet seed phrase. It also covers ENS / GNS / WNS names, EIP-5564 stealth address "profile" concept, and Tornado note import/export. The CLI encrypts your seed on disk, walks you through shield / unshield with prompts, and can run headlessly with --non-interactive for scripts and agents.

Geometric monospace typeface inspired by the Ukrainian Cybernetics School.
Kibernetyk [kʲibɛrˈnɛtɪk] Mono is a geometric monospace inspired by the pioneering spirit of the Ukrainian Cybernetics School. Its rigid, pared-back letterforms recall early mainframe interfaces and the ink-stamped texture of fax transmissions. Drawn from points and lines for clean code, dense data, and the infrastructure that holds them together.

A Claude Code skill that reverse-engineers any animation frame by frame, then proves the copy moves the same.
Reverse-engineer animations you like. Build your own on top. A Claude Code skill that works from a live site, a screen recording, an mp4, a gif or a Lottie file.
A lot of good ideas start on someone else's site. Ask an agent to rebuild one from a link or a screenshot and it makes one pass, calls it done, and misses. It can't see the motion or tell how far off it is.
reanimate records the original, rebuilds it in your code, then records the copy the same way and compares the two. Each round shows what's still off, so the agent keeps going until the numbers match. You end up with a close starting point to make your own.
Local video editor for coding agents: 42 FFmpeg tools with a machine-readable contract and an MCP server, for Claude Code, Cursor and Codex. Cut, captions, reframe, loudness, platform exports. No cloud, no API keys.
A Claude skill that turns vibecoded, AI-looking UI into a designed interface
unslop is a skill for Claude Code and Codex that turns vibecoded, AI-looking UI into a designed interface with its own character. It finds the slop first, the purple gradients, glows, emoji labels, shouty copy and uneven spacing, then sets a direction from your product and fixes the screen pass by pass like a designer doing a redline review. It works in whatever your screen is built with, like Next.js, React, Vue, Svelte, Tailwind or plain HTML and CSS, on dashboards, apps and landing pages, and even on a live site when all you have is a link.
Entire MacOS running in your terminal.
A separate macOS desktop for computer-use agents, viewed and controlled from a terminal.
terminal-mac is an early release candidate for Apple silicon. Apple Virtualization runs a real macOS guest. A bundled helper inside that guest captures its screen and posts input events. A terminal viewer streams that screen using Kitty or iTerm2 graphics. Agent commands use the same helper without moving the physical Mac's pointer or changing its clipboard.
Self-contained user/group management and authentication service.
Portunus was the ancient Roman god of keys and doors. However, this repo does not contain the god. It contains Portunus, a small and self-contained user/group management and authentication service.
Portunus is aimed at individuals and small organizations that want to manage users and permissions across different services, and don't want to deal with the minutiae of LDAP administration.

Static analysis of Android applications, built for stalkerware and mobile malware research.
Drakkar reads an APK, or a raw DEX, and answers one question per mode: which MITRE ATT&CK for Mobile behaviours it implements, whether they are reachable, who signed it, when it was built, what its native code does at the JNI boundary, how close it is to another sample. Every mode prints its own legend: drakkar --<mode> --legend defines each label and each field it emits, and states the limits of each metric.
