## The answer, as recorded

Asked on 2026-09-29 through Claude (Anthropic) with web search (model claude-opus-5).

> ## For most agencies: Sentry first
> 
> **1. Sentry** - The default pick for a dev/web agency. Error tracking + tracing + session replay, organized as separate *projects* under one org, so each client's data stays cleanly separated and you can see at a glance which client site is broken. Pricing is event-based (~$26/mo team tier and up), not per-host, which matters enormously when you're running 30 small client apps instead of one big one - host-based tools would bankrupt you on that shape of work. Weakness: it's app-layer only, not infrastructure.

> **2. New Relic** - Best when clients need full-stack (app + infra + logs + browser) and you want one tool to cover all of it. The 100 GB/month perpetual free tier plus $0.30-0.50/GB after is genuinely useful for an agency: you can onboard small clients at effectively zero cost and only pay as a client's traffic justifies it. User-based seat pricing is the thing to watch if your whole team needs access. ([New Relic](https://newrelic.com/blog/apm/application-performance-monitoring-tools), [S
