Greenroom gives frontend teams the Netlify experience — git-push deploys, preview URLs, one-click sharing — with the guarantee that no data ever leaves your network. Zero internet required.
The data in your prototype is real — patient records, financial accounts, sensitive genealogy. It can't leave the building. Security review denied. Again.
Three days. A Helm chart. A Kubernetes namespace. Repeat for every branch, every iteration. Your designers don't even have cluster access.
Screen recordings. Figma exports. Static screenshots. None of them let anyone actually interact with running software.
The prototype never touches real data until production. Usability issues surface at the worst possible time. The research team tests against fiction.
The entire workflow takes less than a minute. No tickets, no DevOps, no waiting. Everything stays on your network.
Push to GitHub like you always do. Greenroom's webhook picks it up automatically.
→Isolated container build on your infrastructure. Quality scores run automatically.
→A live HTTPS preview URL on your internal network. Paste it in Slack. Stakeholders click and see your work.
→Stakeholders click any element and leave feedback. You resolve comments as you ship fixes. No screenshots required.
No screenshots. No Slack threads. Just click and tell your team what to fix.
Every comment is anchored to the actual UI element — not a screenshot that goes stale with the next deploy.
Resolve comments as you ship fixes. Unresolved count shows in your GitHub PR and your Greenroom dashboard.
Comment notifications fire to your team's Slack channel. The comments themselves never leave your infrastructure.
Netlify and Vercel are extraordinary products — for the public internet. They structurally cannot serve teams behind a firewall.
Vercel and Netlify distribute your artifacts to CDN nodes worldwide. That's their product. Greenroom runs entirely on your hardware.
No Let's Encrypt. No ACME challenge. No external DNS. Greenroom bundles its own CA — the entire TLS chain is self-contained inside Docker.
Bundled CoreDNS resolves wildcard domains to your host. One DNS zone forward from IT — or skip DNS entirely with path-based URLs.
Who deployed what, when, from which commit. For SOC 2, HIPAA, and FedRAMP — the log lives inside your walls, not someone else's.
Your artifacts live in your MinIO instance. Encrypted at rest. Deleted on your schedule. No vendor breach exposes your work.
docker compose up — that's it. The entire platform ships as a single Docker Compose. Runs on any Linux machine. No Kubernetes cluster required. No cloud accounts.
If your organization has both active frontend development and data sensitivity, you're underserved by every existing tool. Greenroom was built for you.
"That sounds like Netlify!" — Yes. Exactly.
But the answer is always no.
The moment that started Greenroom — a Head of UX who just wanted to show his team's work.
Greenroom ships mid-Summer 2026 and is in early access for teams in healthcare, financial services, government, and other high-compliance environments.
