# Murmell > Source: > Published: 2026-08-28 12:42:20+00:00 # Murmell Murmell is a browser-based canvas where several AI coding agents work one project directory, with live terminals and file reservation to stop collisions. ## Overview ## Murmell Murmell is a shared cloud canvas for [AI](/glossary/ai) coding agents. Murmell runs Codex, Claude and Kimi agents inside one project directory in the browser, shows each of them working in a live terminal, and uses file reservation so two agents do not edit the same file at once. Teams watch the same canvas together, which turns [agent](/glossary/agent) work into something a group can follow rather than something happening in one developer's terminal. You connect your own agent subscriptions and [API](/glossary/api) keys; Murmell provides the cloud infrastructure and the coordination layer. **Production credibility:** Murmell launched publicly in August 2026 and publishes its product openly: a browser-based shared canvas, real-time terminals per agent, file reservation to prevent conflicts, and a bring-your-own-keys model where users supply their existing agent subscriptions. It is early — the company is small and pricing is not published on the site — so it is best evaluated as a young product with a specific and well-defined problem rather than as an established platform. ### Key Features - Browser-based canvas shared by a team in real time - Multiple agents — Codex, Claude, Kimi — in one project directory - Live terminal view for each running agent - File reservation to prevent two agents editing the same file - Bring your own agent subscriptions and API keys - Cloud infrastructure managed by Murmell rather than run locally ### Ideal Use Case Small teams that want to run several agents on one codebase and watch the work together — pairing on agent supervision rather than on typing. It suits groups already sharing agent subscriptions who want the coordination handled centrally, and it is a cloud alternative for teams that do not want a local Mac-only setup. ### How Murmell differentiates Conductor solves the parallel-agent problem locally on a Mac; Murmell solves it in the browser for a group. The shared canvas and file reservation are the specific contributions: instead of each developer running their own agents privately, the team sees one workspace and the system arbitrates who edits what. The trade-offs are maturity and trust — it is a new product, pricing is not public, and it needs your agent credentials to run. ### FAQ **Q: What is Murmell?** A: Murmell is a browser-based shared canvas where multiple AI coding agents work in one project directory, with a live terminal for each agent and file reservation to prevent conflicts. **Q: Which agents does Murmell support?** A: Murmell runs agents including Codex, Claude and Kimi. You connect your own agent subscriptions and API keys rather than buying model access from Murmell. **Q: How much does Murmell cost?** A: Pricing is not published on the site. Because you bring your own agent keys, model usage is billed by your existing providers. **Q: How does Murmell prevent agents clashing?** A: Through file reservation: an agent claims the files it is editing, so two agents cannot modify the same file at the same time in the shared directory. **Q: Is Murmell a local or cloud tool?** A: Cloud. It runs in the browser with Murmell managing the infrastructure, which is the main difference from local parallel-agent tools such as Conductor. ### tl;dr Murmell is a browser-based shared canvas for running Codex, Claude and Kimi agents on one project directory, with live terminals, file reservation and team collaboration. Bring your own agent keys; pricing is not published. ## Why Use Murmell ## User Reviews ## Similar Tools [ProductivityClaude CodeAnthropic terminal coding agent that edits, tests, and ships from your shell.Freemium★ 4.92♥ 474](/tools/claude-code) [ProductivityOpenAI CodexCloud software-engineering agent that writes, tests, and ships code in parallel.Freemium★ 4.93♥ 511](/tools/open-ai-codex) [Developer ToolsCursorAI-powered code editor enhancing productivity with intelligent code suggestions and automationPaid★ 4.93♥ 408](/tools/cursor) [ProductivityDevinAutonomous software engineer that ships pull requests from a single ticket.Paid★ 4.93♥ 510](/tools/devin) [Developer ToolsZedZed is an open-source, GPU-accelerated code editor written in Rust with native AI agents and real-time multiplayer collaboration.Freemium★ 4.77♥ 300](/tools/zed)
