Deploy and Host contactkit on Railway

contactkit is a self-hostable contact form backend built with Fastify and TypeScript. It supports Resend and SMTP email providers out of the box and includes a zero-dependency TypeScript SDK for easy client integration.

About Hosting contactkit

Deploying contactkit on Railway takes one click. The template uses a multi-stage Dockerfile for minimal image size, includes a health check endpoint, and auto-restarts on failure. Configure your email provider (Resend or SMTP), set your sender/recipient addresses, and you're live. CORS origins and rate limiting are configurable via environment variables.

Common Use Cases

• Adding a contact form to a static site or JAMstack frontend
• Receiving form submissions via email without managing your own mail server
• Self-hosting a contact API with Turnstile spam protection

Why Deploy contactkit on Railway

Railway provides automatic HTTPS, custom domains, and zero-config deployments from GitHub. contactkit's Dockerfile handles the build pipeline, and Railway's health checks ensure zero-downtime deploys. Environment variables are managed securely through the Railway dashboard — no .env files to juggle in production.
