> Short answer up front: for most agencies the winning combo is **Sentry for the app-level truth + a white-label uptime tool for the client-facing story**. Here's the ranked list and why.
> 
> ## 1. Sentry - default pick for most agencies
> Per-project separation is the whole model, so each client gets its own project, its own alert rules, and its own quota inside one org. Errors + tracing + session replay in one tool, and pricing starts around $26/mo scaling on event volume. Best agency fit because you can onboard a new client project in minutes without a new contract. Weak spot: event-based pricing means a single client's broken deploy can eat your shared quota - set per-project spend caps on day one.
> 
> ## 2. AppSignal - best economics if you run many small client apps
> Charges per request and includes **unlimited apps, users, and teams** with no overage fees or per-seat costs. That's the pricing shape agencies actually want: 30 client Rails/Node/Elixir apps don't cost 30× a single app. If your portfolio is lots of medium-traffic sites rather than a few big ones, this usually beats Sentry and Datadog on total spend.

> ## 3. Datadog - only when clients have real infrastructure
