Summary

Adds a Railway one-click deploy template to the Hosting Guides section of the self-hosting docs.

The template deploys the full self-hosting stack on Railway:

  • server: InstantDB backend API (ghcr.io/instantdb/server:latest)
  • dashboard: InstantDB dashboard UI (ghcr.io/instantdb/dashboard:latest)
  • postgres: Postgres 16 with pg_hint_plan (InstantDB-compatible image)
  • instantdb-storage: Railway Bucket (S3-compatible object storage)

This gives people a quick way to try self-hosted Instant without provisioning a VPS or AWS infra manually.

Notes

  • I'm the template creator (orenaksakal); happy to adjust wording/placement.
  • Kept the change minimal — a single list item in the existing Hosting Guides section.

Addressed both review findings in fe2a91d:

  • railway/page.md (Scaling): Removed the recommendation to add server replicas. The section now covers vertical scaling only and notes that multi-replica deployments require shared configuration plus Hazelcast/gRPC service discovery, linking to horizontal scaling in the overview.
  • page.md (agent instructions): The agent decision flow now includes Railway (/docs/self-hosting/railway.md) alongside VPS, AWS, and Migrate.
