Dynos · $25/mo (32 vCPU)
Railway's Hobby plan offers dramatically better raw specs (48 vCPU, 48 GB RAM) at $5/mo with $5 included credit, making it 5-80x cheaper than Heroku's $25-$2,400 range for equivalent workloads. However, Railway's per-second metering and lack of published SLA create real risk for production use, while Heroku's hidden costs (Postgres reliability cliffs, add-on overages, performance dyno provisioning delays) are equally concerning.
Includes $5 monthly credit, 48 vCPU and 48 GB RAM at entry price, and per-second billing means you only pay for what you use.
Caveat: No published SLA, metered overages can spike costs unpredictably under load, and egress charges ($0.05/GB) are separate; best for side projects and solo developers, not production.
