Everything you need

A complete toolkit for running parallel AI coding agents.

Parallel AI Agents

Run multiple agents in isolated worktrees simultaneously. Each gets its own branch, terminal, and environment.

One-Click Worktrees

Create worktrees with AI-powered branch naming. Describe the task, and webmux handles the rest.

Real-Time Terminals

Live WebSocket terminal streaming in the browser. Watch agents work, send prompts, and switch instantly.

PR & CI Integration

PR status, CI check results, and review comments displayed inline next to each worktree.

Linear Issues

Browse and assign Linear issues directly. Auto-link branches to issues for seamless tracking.

Docker Sandboxing

Isolated containers with automatic port forwarding and volume mounts for untrusted workloads.

Create & Manage Worktrees

Spin up new worktrees with one click. Pick a profile, type a prompt, and webmux creates the worktree, starts the agent, and begins streaming output. Merge or remove worktrees when you're done.

PR, CI & Comments

See pull request status, CI check results, and review comments right next to each worktree. No more switching to GitHub to check if your agent's PR passed CI.

Service Health Monitoring

Track dev server ports across worktrees. webmux polls configured services and shows live health badges so you know which worktrees have their servers running.

Linear Integration

See your assigned Linear issues alongside your worktrees. Webmux matches branches to issues automatically, so you can browse your backlog, pick an issue, and spin up a worktree for it in one click.

One config file. Full control.

Define worktree layout, service ports, agent profiles, and Docker sandboxes in a single YAML file.
