so i've been running posthive + 2 other projects on railway hobby plan for a while now and was curious what it actually costs
here's the breakdown:
posthive api (fastify + bullmq + sqlite) sitting at 136mb ram-> $0.59/month redis for the job queue, only using 12mb memory, 300mb volume for rdb snapshots -> $0.12/month two other projects -> $1.63/month
total so far this month: $2.58, estimated end of month: $3.32
the thing i like about railway billing is it's based on memory + cpu time, not requests. so traffic spikes don't really affect the cost. egress is free tier too.
kept redis lean by configuring bullmq to only keep the last 100 completed and 200 failed jobs so it doesn't just accumulate forever
for the docker setup i'm building multi-arch images (amd64 + arm64) on ghcr with github actions layer caching, and a paths filter so doc-only commits don't trigger a rebuild
