Deploy and Host Sazabi Log Forwarder on Railway

Sazabi Log Forwarder sends the deploy logs and HTTP logs of every service in your Railway environment to Sazabi, with no code changes. It runs as one extra service, reads logs from Railway's API, and forwards them to Sazabi over OpenTelemetry (OTLP/HTTP).

About Hosting Sazabi Log Forwarder

Railway has no log drain, so the forwarder runs inside your project. It subscribes to deploy logs for the whole environment, including services you add later, and to HTTP logs for every service with a public domain. Each log carries service, environment, project, and deployment attributes. HTTP 5xx responses become errors and 4xx become warnings. The forwarder has no public networking and no volume. You need two values: the intake URL of a Sazabi Railway log source, and a Railway account token. An account token can read every project in your Railway account; the forwarder only reads its own environment.

Common Use Cases

Search and alert on the deploy logs of every Railway service in one place
Track HTTP errors and slow requests across services with public domains
Give Sazabi's AI the production logs it needs to investigate incidents

Dependencies for Sazabi Log Forwarder Hosting
