Deploy and Host

Deploy Traffic Source on Railway with one click. Railway handles builds, SSL, and domain provisioning automatically — no server configuration needed.

About Hosting

Traffic Source runs as a single Next.js service on Railway. Your analytics data is stored in a SQLite database file on a persistent Railway Volume — no external database required. Railway auto-provisions a public HTTPS domain and injects it into your environment on deploy.

Make sure the Volume is mounted to ./data so your database survives redeployments.

Why Deploy

• No monthly SaaS fees — Pay only for Railway usage (~$5/mo for low-traffic)
• Full data ownership — All analytics stay on your Railway instance
• One-click setup — No Nginx, PM2, or VPS configuration required
• Auto-scaling — Railway handles traffic spikes without manual intervention
• Built-in SSL — HTTPS domain provisioned automatically on deploy

Common Use Cases

• Indie hackers and solo founders who want analytics without paying $20+/mo for Plausible or Fathom
• SaaS products that need Stripe conversion tracking tied to visitor sessions
• Products with affiliate programs needing referral link tracking and commission dashboards
• Developers who want full ownership of their analytics data without relying on third-party services
• Multi-product portfolios that need to track multiple sites from a single dashboard
