Open Source Alternative to Vercel, Netlify, Railway, Render and Neon.

Build, deploy, and run from one open-source platform. Your apps run on your server.

Demo: demo.frost.build

Why Frost

  • Open source runtime. No platform markup.
  • Git push deploy workflow.
  • Docker-native. No Kubernetes setup.
  • AI-friendly deploy model with clear logs.

What you get

  • Unlimited services, deploys, and seats
  • Automatic SSL (Let's Encrypt)
  • Custom domains and redirects
  • PR preview environments
  • Zero-downtime deploys and instant rollbacks
  • Health checks, resource limits, persistent volumes
  • REST API and MCP support for AI agents

Core model

  • Project: container for related services with shared env vars
  • Service: deployable unit from repo or prebuilt image
  • Domain: custom domain attached to a service (proxy or redirect)
  • Deployment: immutable deploy record with logs and status

Services in one project share a Docker network. Use service name as hostname.

Install

With AI agent:

  • Give your agent https://frost.build/install.md

Manual:

curl -fsSL https://frost.build/install.sh | sudo bash

Need VPS provisioning help: INSTALL.md

One simple deploy example

Create a project, deploy, then check status:

PROJECT_ID=$(curl -s -X POST http://localhost:3000/api/projects \
  -H "Content-Type: application/json" \
  -d '{"name":"demo","repo_url":"./test/fixtures/simple-node","port":3000}' | jq -r .id)

DEPLOYMENT_ID=$(curl -s -X POST "http://localhost:3000/api/projects/$PROJECT_ID/deploy" | jq -r '.deploymentIds[0]')

curl "http://localhost:3000/api/deployments/$DEPLOYMENT_ID"
