A Google Zanzibar-inspired authorization service for defining, checking, and auditing fine-grained access control across your applications.

A temporal code knowledge graph with blast-radius impact scoring, semantic symbol search, and git-history-aware dependency analysis for AI-assisted development — zero required runtime dependencies, SQLite-backed.

An AI-powered personal news aggregator that filters multi-source feeds through LLMs and delivers curated, noise-free summaries to your Notion workspace.

Self-hosted, open-source Vercel alternative that deploys Python, Node.js, PHP, and any Docker-compatible app from a Git push, with zero-downtime rollouts and real-time logs.

Record live API traffic and replay it as deterministic, sandboxed tests, plus AI code review and unit test generation, all from one Go CLI built by YC W2024's Use-Tusk.

Self-hosted SEO auditing that crawls your entire website and surfaces critical issues — broken links, duplicate meta tags, redirect loops, and more — before they hurt your rankings.

Train a locally hosted AI twin on your own memories—then connect it to the world through a decentralized identity network.

kubectl for AI Agents — manage, schedule, and scale your AI workforce with a single binary that deploys in seconds.

Deploy a self-hosted status page with endpoint monitoring and automatic HTTPS in minutes, with no external dependencies required.

Give an AI agent a real LLM training setup and let it experiment autonomously overnight — you wake up to a log of experiments and (hopefully) a better model.

Ephemeral, VM-isolated "Agent Computers" for AI agents — a Kubernetes-native REST API backed by Kata Containers microVMs.

Self-hosted backup automation for Ubuntu and Debian servers with S3 storage, SSH-based file and database backup, and multi-channel notifications.

Build internal tools and admin panels faster with AI-generated Python code, fully self-hosted and local-first.

A production kit that turns AI-generated character motion into reviewable 256x256 sprite sheets — frame extraction, background cleanup, strip packing, browser-based inspection, and approval promotion.
