Sovereign Composable Tools

Local-first tools for open protocols

We build Unix-style command-line tools for the decentralized social web. Each tool does one thing well and composes naturally with pipes and scripts.

Why?

The social web is fracturing into walled gardens. We believe in:

Your data, your machine - Local-first, no cloud dependencies
Open protocols - Nostr, ActivityPub, SSB - not corporate APIs
Unix philosophy - Small tools that compose via stdin/stdout
Agent-friendly - JSON output, meaningful exit codes, scriptable
