Own your AI infrastructure instead of renting it by the token. One subscription. Your box. Your terms.
You were sold a meter — intelligence rented by the token, your data through someone else's pipes, your tools on someone else's roadmap and someone else's pricing meeting. I'm building the opposite: a stack you actually own. The open tools are the door; a real autonomous studio running in production is the proof — the unfinished parts included.
| dario | own your routing — your Claude subscription in any tool (Cursor, Cline, Aider, the Agent SDK), at subscription pricing, not per-token bills |  |
| hybrid | own your inference — local-first LLM routing: answer the easy majority on a small local model, escalate only the genuinely hard queries to the frontier; nothing paid or sent off your machine for the rest |  |
| deja | own your LLM cache — a hybrid exact + semantic caching proxy; repeat and near-repeat queries serve from your cache, not the provider's meter |  |
| deepdive | own your research — a local agent that plans, searches, reads, and synthesizes a cited answer, through your own router |  |
| hands | own your computer-use — your LLM on your own mouse, keyboard, and screen, with an audit log of everything it does |  |
| agent | own your fleet — connect any device, run the shell or Claude Code tasks the fleet dispatches |  |
| warden | own your agent security — a firewall for every agent tool call: blocks RCE, secret-exfil, SSRF, and prompt-injection / poisoned MCP tools, with a tamper-evident audit |  |
| canon | own your agent skills — vet, sign & pin every skill & MCP server before it runs; drift detection catches a poisoned or silently-updated tool before it ever loads |  |
| keeper | own your agent secrets — an encrypted vault that hands agents scoped, short-lived, single-use leases instead of raw keys; the key never enters the agent's context, and every access is audited |  |
| browser-bridge | own your browser — stealth headless Chromium in a container, CDP on your own endpoint |  |
| claude-sync | own your sessions — move Claude Code sessions across machines, byte-identical |  |
| amnesia | own your search — privacy-first metasearch, 155 engines at once, zero tracking, no AI, VPN-tunneled |  |
| askalf | own your operation — the self-hosted AI workforce platform the whole stack runs | early access |
warden · canon · keeper compose into one layered defense → agent-security-stack — vet the tool, contain the call, give it a key it never holds.

It's hard, and it's not finished — that's the point. The value isn't a demo; it's the scars from running agents in production for real. I write down what actually happens.
