Proliferate is a desktop and web app for running coding agents in parallel, locally or in cloud sandboxes. Each agent runs through its own native harness.

• Run any mix of agents in parallel, each in its own isolated worktree or sandbox, with native tools, auth, and config intact
• Let your agents manage each other, like having Codex hand design work to Claude Code
• Set up MCPs and skills once, shared across every agent

Each agent runs through its native harness, so auth, tools, models, permissions, and transcript behavior stay intact. New harness features show up in Proliferate the day they ship.

• 🤖 Native harnesses - Claude Code, Codex, Gemini CLI, OpenCode, Cursor, and more
• 🌳 Worktree workspaces - an isolated branch and working directory for every task
• 🔍 Git & diff review - inspect and edit agent changes without leaving the app
• 🛡️ Plan & code review agents - reviewer agents check plans, diffs, risks, and branch readiness before you do
• 🪆 Subagents - agents delegate investigation, implementation, and review to other agents
• 🧩 Plugins - MCPs, skills, Computer Use, Browser Use, and custom tools, configured once and shared by every agent
• ⏰ Automations - run any agent on any schedule
• 🖼️ Artifacts - docs, UI, demos, and components rendered inline as agents produce them

Proliferate is AGPL-3.0. The desktop and web apps are fully open today, and self-hosting for the complete cloud control plane is coming soon.

• 👥 Multiplayer cloud chats - live sessions your team can inspect, claim, and continue
• 💬 Team Slackbot - turn a Slack message into shared agent work for the whole team
• 🤝 Team automations - shared recurring fixes and reviews the whole team can run
• 🛰️ Remote dispatch - kick off and steer work on your own machine from the web
• 🔑 SSH access - drop into any cloud sandbox from your terminal
