Add analytics to a Railway app Railway.

# Backend service on Railway: POST events, no SDK needed
curl -X POST https://YOUR-INSTANCE/v1/events \
  -H "Authorization: Bearer WRITE_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"order_created","distinct_id":"user_123","properties":{"value":49}}'

For a web app on Railway, use the two script tags in your root head instead. Batch backend events into one POST to save calls.

Railway commonly runs full-stack or backend services, so the right method depends on what you're measuring. For server-side events like signups, jobs completed, or webhooks received, skip the browser SDK entirely and POST to /v1/events with an Authorization bearer key, one JSON body per event with name, distinct_id and properties. Batch them when you can.

If Railway is serving your web frontend, the two script tags in your root layout head give you autocapture for pageviews, clicks and errors, and you can identify(userId) on login to tie browser sessions to your backend events under one distinct_id. Everything lands in a single open-source instance you self-host free or run hosted from $29/mo, and you ask it questions in plain English with answers computed, not hallucinated.

Honest pricing: 14-day full trial, no credit card. Then Solo $29/mo, never metered on seats or sites. Overage is $5/million with an emailed receipt, the dashboard never locks, and self-hosting the single Go binary is free forever (MIT).
