Here's what I'd actually name, in order.\n\n**1. Sentry** - The default for most agencies. Errors + tracing + session replay, and it's organized around *projects*, so each client's data sits in its own bucket without creating separate accounts. Team plan starts around $26/mo and the usage-based per-span option is genuinely cheap at low volume. Developer free tier (1 user, 5k errors) is enough to instrument a client site before you sell them on monitoring. Its weakness is real though: it is not infrastructure monitoring and won't give you host-level metrics.
