As answered by people managing Diffee and Bellows AI App.
Bellows AI App's answer:
Developers who already use coding agents and want to stay in control of them: people who run more than one agent, people pairing with a colleague on a live agent session, and small teams that need one set of rules and a record of what each agent was allowed to do.
Bellows AI App's answer:
You can hand a colleague a link to the coding agent you're running. They watch it work live in their browser, with no install and no account, and suggest changes, but nothing reaches the agent until you accept it. Every decision, yours and theirs, lands on a hash-linked audit trail. And it works with any agent that speaks the Agent Client Protocol, not just one vendor's.
Bellows AI App's answer:
It runs on Windows, Mac and Linux, while Conductor is Mac-only today. Live sharing costs $19 per seat on the Team plan, against Conductor's $60 per user. Sharing on your own network is free. Bellows isn't tied to one agent: Claude, Codex, Gemini CLI, Qwen Code, any ACP agent and local models all run side by side under one set of permission rules.
Bellows AI App's answer:
Electron and Node.js for the desktop app, the Claude Agent SDK and the Agent Client Protocol (ACP) for driving agents, Next.js, Supabase and Vercel for the website and team control plane, Stripe for billing, and a Cloudflare Workers relay that forwards end-to-end encrypted frames for sharing.
Bellows AI App's answer:
I was building an app with a colleague, and the coding agents were fast but working together wasn't. Every big decision turned into a thread of emails and WhatsApp messages, waiting on each other's replies, when what we wanted was to sit at the same agent and decide it together, live.
The other push came from work. My employer wouldn't let us use AI coding tools at all, because nothing they did was audited: no record of what an agent was allowed to do, or who said yes.
So Bellows does both. You share a running agent session with a link, your colleague watches it work and suggests changes, and nothing runs until you accept it. Every decision lands on a hash-linked audit trail, under one set of rules for the whole team. It works with any agent that speaks the Agent Client Protocol, because we didn't want to bet on one vendor. Version 1.0 shipped in September 2026.
