Frost

Frost is an open-source platform for building, deploying, and running applications on your own infrastructure. It provides a git-based deployment workflow similar to commercial platforms, supporting Docker containers, multiple databases, and PR preview environments. The project describes itself as an alternative to Vercel, Netlify, Railway, Render, and Neon. According to build evidence, it was developed with Claude and Codex AI coding tools.

The platform includes automatic SSL certificates, custom domains, zero-downtime deploys, instant rollbacks, health checks, and S3-compatible object storage. It supports long-running background jobs without timeout limits and integrates with AI coding agents via MCP (Model Context Protocol), allowing developers to deploy directly from their editor. Frost runs on standard VPS infrastructure with no vendor lock-in.
