Patchbay is the plumbing that lets me run a whole software studio from a phone.
It started as one piece, a Telegram bridge, and grew into a small family. Each part is a different surface onto the same idea: the human gives instructions and reviews results, and everything else runs headless on a Mac in another room. Text, voice, and one-tap links into native apps, all riding the same phone-only workflow.
Three tools, each with its own page and repo.
Patchbay Relay /Telegram Bridge
The bridge that puts AI coding agents on a phone. It maps Telegram threads to working directories, spawns or resumes a session on the right harness (the Claude Agent SDK, the SDK with MOP filtering, or pi), and streams the responses back. Multi-project routing, agent identity loading, and crash recovery are built in. Read more →
Patchbay Voice /iOS Voice Client
Hold-to-talk when text hits its ceiling. Record a request, hear a spoken reply, with sessions scoped per repo so each project keeps its own context. A single write directory bounds where the agent can save files. An iOS app and a web client, backed by a small server you run yourself. Read more →
Patchbay Go /Tappable Links
A tiny Cloudflare Pages worker that wraps custom URL schemes (obsidian://, things://, calshow:) in plain https:// links, so an agent can hand you a one-tap link straight into a native app from a chat message. Built for the headless Telegram workflow, useful anywhere a chat app refuses to render a custom scheme. Read more →
