The decision, in plain words

For a solo builder at 50,000 error events/month and a $50.00/mo budget for the monitoring platform slot, Sentry leads at 93% fit and $28.50/mo. The two rules doing the work: budget fit (~$28.5/mo is 57% of your $50/mo budget); batteries included (Bundles log management, session replay, tracing/APM, uptime monitoring — fewer services to glue at team size 1).

The gap to Datadog (83% fit) is wide at these inputs — you'd need to change your requirements, not your taste, to flip it.

Generated from the calculation above — every number traces to the sourced data; nothing here is written by an AI making things up.

Ecosystem maturity (weight 8, our estimate) — established — our estimate from ecosystem age, docs and hiring pool+8

Free-tier runway (weight 10, our estimate) — Free tier exists (5K errors + 5GB logs + 5M spans/month, 1 user, 30-day lookback) — a cheap staging/dev lane even after you outgrow it+4
