Now in early access
Spin up isolated Firecracker microVMs with persistent storage, public HTTPS URLs, and built-in AI coding agents. Invite teammates to share an agent session and work together on the same repo.
Real Linux VMs, not containers. Full isolation, root access, and a public URL — per environment.
Each env is a real Linux VM — full isolation, not a container. Alpine Linux, SSH access, root permissions.
Every environment gets {slug}.numavm.com with automatic HTTPS. Share a running app with one link.
Env URLs are protected by GitHub/Google login. Grant access to collaborators by email.
Run Codex, Claude Code, or OpenCode from the dashboard. Chat UI with streaming, tool calls, and approval prompts.
Invite teammates to the same agent session and repo. Everyone can pick up where the last person left off.
Full xterm.js terminal in the browser over WebSocket. No local SSH client needed.
Each env auto-creates a GitHub repo (or uses an existing one). Code is cloned into the VM on boot.
VMs snapshot after 15 min idle. Sub-second restore on next request. Pay for compute only when active.
Each VM has its own ext4 disk. Files survive restarts and snapshots.
From zero to a live, shareable dev environment in under a minute.
Pick a name and optionally link a GitHub repo. A Firecracker microVM boots in seconds with your code cloned and ready.
Use the built-in web terminal, or let an AI agent write code for you. Full root access, real Linux — no compromises.
Your app is live at {slug}.numavm.com with HTTPS and OAuth. Send the link — teammates log in, see the running app, and jump into the same agent session.
Your dev environment lives in the cloud. Access it from whatever you have in front of you.
Full web terminal and AI agent dashboard from any browser. Open a tab and you're in.
Check logs, run commands, or chat with an AI agent from your phone. Same dashboard, fully responsive.
SSH directly into your VM from any terminal. Use your own editor, your own dotfiles, your own workflow.
Run any supported coding agent from the browser. Streaming output, tool call visibility, and human-in-the-loop approval — built in.
by OpenAI
Coding agent running via JSON-RPC app-server protocol. Reads your codebase, proposes changes, and applies them with your approval.
by Anthropic
CLI-based coding agent accessible via SSH. Understands full project context and can run commands, edit files, and iterate on code.
Open Source
Open-source coding agent running as an HTTP server inside the VM. Lightweight, extensible, and community-driven.
