Instant cloud dev environments
with AI agents built in

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.

Everything you need to code in the cloud

Real Linux VMs, not containers. Full isolation, root access, and a public URL — per environment.

Firecracker MicroVMs

Each env is a real Linux VM — full isolation, not a container. Alpine Linux, SSH access, root permissions.

Public Subdomain per Env

Every environment gets {slug}.numavm.com with automatic HTTPS. Share a running app with one link.

OAuth-Gated Access

Env URLs are protected by GitHub/Google login. Grant access to collaborators by email.

AI Agents Built In

Run Codex, Claude Code, or OpenCode from the dashboard. Chat UI with streaming, tool calls, and approval prompts.

Shared Agent Sessions

Invite teammates to the same agent session and repo. Everyone can pick up where the last person left off.

Web Terminal

Full xterm.js terminal in the browser over WebSocket. No local SSH client needed.

GitHub Integration

Each env auto-creates a GitHub repo (or uses an existing one). Code is cloned into the VM on boot.

Idle Snapshot & Wake

VMs snapshot after 15 min idle. Sub-second restore on next request. Pay for compute only when active.

Persistent Storage

Each VM has its own ext4 disk. Files survive restarts and snapshots.

Up and running in three steps

From zero to a live, shareable dev environment in under a minute.

1

Create an environment

Pick a name and optionally link a GitHub repo. A Firecracker microVM boots in seconds with your code cloned and ready.

2

Code in the browser

Use the built-in web terminal, or let an AI agent write code for you. Full root access, real Linux — no compromises.

3

Share with your team

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.

Run from anywhere

Your dev environment lives in the cloud. Access it from whatever you have in front of you.

Browser

Full web terminal and AI agent dashboard from any browser. Open a tab and you're in.

Mobile

Check logs, run commands, or chat with an AI agent from your phone. Same dashboard, fully responsive.

CLI & SSH

SSH directly into your VM from any terminal. Use your own editor, your own dotfiles, your own workflow.

One environment. Every device. No sync, no setup, no "works on my machine."

Three AI agents, one dashboard

Run any supported coding agent from the browser. Streaming output, tool call visibility, and human-in-the-loop approval — built in.

Codex

by OpenAI

Coding agent running via JSON-RPC app-server protocol. Reads your codebase, proposes changes, and applies them with your approval.

Claude Code

by Anthropic

CLI-based coding agent accessible via SSH. Understands full project context and can run commands, edit files, and iterate on code.

OpenCode

Open Source

Open-source coding agent running as an HTTP server inside the VM. Lightweight, extensible, and community-driven.

All three stream to the same chat UI with tool call visibility, file diffs, and human-in-the-loop approval prompts. Share any session with teammates — they see the full history and can continue the conversation.
