The question asked, verbatim: best error monitoring tools for agencies

Brands named, in the order the engine gave

1. Sentry mentioned
   Sentry - the default, and for good reason.
2. WordPress mentioned
   Broadest SDK coverage (PHP/WordPress, Laravel, Rails, Node, React, React Native), release tracking so you know which deploy broke it, and session replay on the higher tier is genuinely useful when a client says "it was broken" with no other detail.
3. GlitchTip recommended
   GlitchTip - my pick if you want to own the stack or keep margin.
4. Postgres mentioned
   Runs as a lean Django + Postgres app rather than Sentry's twenty-container self-hosted monster, and it bundles uptime monitoring, which for agency retainers is half of what clients actually care about.
5. Rollbar mentioned
   Rollbar - worth a look if Sentry's quota math annoys you.
6. AppSignal mentioned
   AppSignal - the best fit if your agency is concentrated in Rails, Elixir, or Node.
7. Bugsnag mentioned
   Bugsnag (now SmartBear Insight Hub) - reach for this specifically when you're shipping client mobile apps.
8. you're mentioned
   Bugsnag (now SmartBear Insight Hub) - reach for this specifically when you're shipping client mobile apps.
9. LogRocket mentioned
   LogRocket - not a primary error tracker, a supplement.
10. high-value mentioned
    Add it on the one or two high-value clients where you're arguing about whether a bug is real: it gives you the session replay plus network/state context that turns "can't reproduce" into a 30-second video.
11. Datadog mentioned
    Two I'd skip for agency work: Datadog, which is excellent but priced and structured for one large org, not thirty small ones - the per-host billing punishes a fragmented client base;
12. Firebase Crashlytics mentioned
    and Firebase Crashlytics, which is free and fine but Android/iOS only, so it can't be your standard.

The answer, as recorded

For an agency the constraint is different from a product team: you have many small projects rather than one big one, you need clean separation per client, and the cost per project has to stay small enough to either absorb or bill through. Here's what I'd actually reach for, in order: **1. Sentry** - the default, and for good reason. One org, unlimited projects, and the quota is pooled across all of them, which is exactly the shape an agency wants: 30 client sites that each throw a few hundred errors a month share one bucket instead of 30 subscriptions. Teams + per-project permissions let you scope a client's own devs to just their project. Broadest SDK coverage (PHP/WordPress, Laravel, Rails, Node, React, React Native), release tracking so you know which deploy broke it, and session replay on the higher tier is genuinely useful when a client says "it was broken" with no other detail. Team plan is ~$26/mo for 50k errors. The catch is that quotas get eaten fast by one noisy client, so set per-project spend caps on day one. ([sentry pricing overview via comparison](https://www.stackfyi.com/guides/error-tracking-sentry-vs-rollbar-vs-bugsnag-2026)) **2. GlitchTip** - my pick if you want to own the stack or keep margin. It's Sentry-SDK-compatible, so you point the same DSN somewhere else and nothing in your code changes - which also means it's a low-risk hedge: instrument with Sentry SDKs, switch backends later if pricing turns. Runs as a lean Django + Postgres app rather than Sentry's twenty-container self-hosted monster, and it bundles uptime monitoring, which for agency retainers is half of what clients actually care about. Free self-hosted, ~$15/mo hosted. Feature set is deliberately thinner - no profiling, limited replay. ([glitchtip.com](https://glitchtip.com/), [danubedata.ro](https://danubedata.ro/blog/self-host-sentry-glitchtip-error-tracking-2026)) **3. Rollbar** - worth a look if Sentry's quota math annoys you. Lower entry price (~$9/mo, free tier at 25k events), and its grouping/deduplication is the thing people stay for - it keeps one flapping client from burying the other twenty-nine in your alert channel. Narrower platform than Sentry, which is fine if you only want error tracking. ([rollbar.com](https://rollbar.com/blog/best-error-monitoring-tools/)) **4. AppSignal** - the best fit if your agency is concentrated in Rails, Elixir, or Node. Flat, predictable per-host pricing rather than event-metered, and it folds errors, performance, logs, uptime, and host metrics into one dashboard, so it can replace two or three tools on a retainer. Less appealing if your client mix is polyglot. ([betterstack comparison](https://betterstack.com/community/comparisons/error-tracking-tools/)) **5. Bugsnag (now SmartBear Insight Hub)** - reach for this specifically when you're shipping client mobile apps. Its stability-score model ("what % of sessions were crash-free in this release") is the cleanest way to report app health to a non-technical client, and release-over-release comparison is its strength. Overkill and relatively pricey for a portfolio of brochure sites. ([rollbar.com/blog/bugsnag-alternatives](https://rollbar.com/blog/bugsnag-alternatives/)) **6. LogRocket** - not a primary error tracker, a supplement. Add it on the one or two high-value clients where you're arguing about whether a bug is real: it gives you the session replay plus network/state context that turns "can't reproduce" into a 30-second video. Too expensive to run across a whole client roster. ([saucelabs roundup](https://saucelabs.com/resources/blog/the-best-error-reporting-and-crash-monitoring-tools-of-2026)) Two I'd skip for agency work: **Datadog**, which is excellent but priced and structured for one large org, not thirty small ones - the per-host billing punishes a fragmented client base; and **Firebase Crashlytics**, which is free and fine but Android/iOS only, so it can't be your standard. Practical advice regardless of pick: standardize on one tool across every client rather than inheriting whatever each client set up, use a consistent project naming convention plus environment tags (`client-prod`, `client-staging`), and set per-project rate limits before onboarding - the failure mode for agencies is always one runaway project consuming the shared quota silently.
