We built NumaVM because setting up a dev environment shouldn’t take longer than writing the code.

The problem

Every team we’ve talked to has the same story: onboarding a new engineer takes a day (or more) of installing dependencies, cloning repos, configuring secrets, and debugging “works on my machine” issues. Remote dev environments promise to fix this, but most solutions are either too slow, too locked-down, or too expensive.

What NumaVM does differently

NumaVM gives each developer a real Linux VM — not a container — powered by Firecracker. Each environment boots in about a second, gets its own public HTTPS subdomain, and comes with a web terminal and three built-in AI coding agents.

Firecracker microVMs

Containers share a kernel. That’s fine for production, but for development you want root access, systemd, custom kernels, and full isolation. Firecracker gives you all of that with near-container startup times.

Public URLs out of the box

Every environment gets {slug}.numavm.com with automatic HTTPS and OAuth-gated access. Share a running app with your team by sending a link — no ngrok, no port forwarding, no VPN.

AI agents in the browser

Run Codex, Claude Code, or OpenCode directly from the NumaVM dashboard. Each agent streams its output to a chat UI with tool call visibility and human-in-the-loop approval. Invite a teammate to the same session and pick up where they left off.

What’s next

We’re in early access right now. If you want to try NumaVM, sign up here — no credit card required.

We’re working on:

Persistent snapshots — idle VMs snapshot automatically and restore in under a second
GitHub App integration — auto-create environments from PRs
Team workspaces — shared billing, access controls, and environment templates
