Railway Plans · $5/mo (48 GB RAM, 48 vCPU, 5 GB SSD)
Railway's Hobby tier is genuinely cheap at $5/mo with included credit, but the per-second overage billing and egress charges create real risk for variable workloads. Heroku's Fir dynos start at $25/mo and lack transparent per-tier specs, making direct comparison difficult; neither option is clearly superior without knowing your actual usage pattern.
Heroku's Fir dynos offer predictable flat-rate pricing with no per-second metering, eliminating surprise overage bills if your app spikes under load.
Caveat: Heroku does not publish granular per-tier specs for Fir dynos, so you cannot verify exact CPU/RAM allocation; pricing range is $25-$2,400/mo across families, creating uncertainty.
