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

Brands named, in the order the engine gave

1. Sentry mentioned
   Sentry - the default answer for most agencies.
2. Spend Allocation mentioned
   Two caveats: billing is per-org, though Spend Allocation lets you reserve event volume per project, which is the closest thing to per-client cost attribution.
3. GlitchTip mentioned
   GlitchTip - if you're cost-sensitive or want to white-label.
4. Postgres mentioned
   Runs on just an app server, Postgres, and Redis/Valkey, so it's genuinely cheap to host (~$5-10/mo flat for unlimited events and projects) rather than Sentry's heavy self-hosted stack.
5. Rollbar mentioned
   Rollbar - cheapest credible paid entry point.
6. Bugsnag mentioned
   Bugsnag (SmartBear Insight Hub) - if client work is mobile-heavy.
7. SmartBear Insight Hub mentioned
   Bugsnag (SmartBear Insight Hub) - if client work is mobile-heavy.
8. Honeybadger mentioned
   Honeybadger - small-team simplicity, Ruby/Rails especially.
9. Ruby mentioned
   Honeybadger - small-team simplicity, Ruby/Rails especially.
10. PostHog mentioned
    PostHog - only if you're already on it.
11. Scout APM mentioned
    - Best Sentry alternatives (Scout APM) (https://www.scoutapm.com/blog/sentry-alternatives)

The answer, as recorded

Here's what I'd actually recommend, in order. The agency-specific wrinkle worth knowing up front: almost all of these bill at the **organization** level, not per project - so if you want clean per-client invoicing, you either run a separate org/account per client or allocate internally. **1. Sentry - the default answer for most agencies.** Unlimited projects and unlimited team members on the Team plan (~$26/mo annual, 50k errors; Business ~$80/mo), which is the key property for agencies: you can spin up a project per client site at no incremental seat cost. Best SDK coverage of anything here, and release/commit tracking ties an error back to the specific deploy - valuable when you're explaining to a client why their site broke on Tuesday. Two caveats: billing is per-org, though **Spend Allocation** lets you reserve event volume per project, which is the closest thing to per-client cost attribution. And per-project rate limits matter a lot when one noisy client app can eat the shared event quota. **2. GlitchTip - if you're cost-sensitive or want to white-label.** Open source, self-hosted, and drop-in compatible with Sentry's SDKs - you point an existing Sentry DSN at your GlitchTip instance and nothing else changes. Runs on just an app server, Postgres, and Redis/Valkey, so it's genuinely cheap to host (~$5-10/mo flat for unlimited events and projects) rather than Sentry's heavy self-hosted stack. For an agency this is the one that lets you put error tracking on your own domain and resell it as part of a retainer. Trade-off: fewer features, and you own the uptime. **3. Rollbar - cheapest credible paid entry point.** Essentials around $13/mo with a 5k/month free tier, and usage-based pricing that flexes when client error volumes are spiky rather than steady. Good language breadth. I'd pick this over Sentry mainly if your portfolio is many small, low-traffic sites. **4. Bugsnag (SmartBear Insight Hub) - if client work is mobile-heavy.** Starts around $59/mo (Team), pricier than the rest, but the strongest mobile story: iOS, Android, React Native, Flutter, Unity, with per-device pricing and stability-score-based release gating. If you ship client apps to the App Store, this is the one worth the premium. **5. Honeybadger - small-team simplicity, Ruby/Rails especially.** ~$26/mo for 50k errors, flat monthly pricing so invoices don't surprise you. It bundles error tracking + uptime + cron monitoring in one tool, which cuts down the number of dashboards you hand clients. Weaker outside Ruby/Rails than Sentry or Rollbar. **6. PostHog - only if you're already on it.** Absorbed error tracking into its analytics product, and the free tier (100k exception events/mo) is the most generous going. Not a serious standalone choice for agency error monitoring, but free consolidation if PostHog is already in your stack. One thing to add alongside any of the above: these are **error** monitors, not **uptime** monitors. Clients notice downtime, not stack traces, so pair your pick with an uptime tool that produces client-facing status pages on custom domains - Honeybadger covers both, otherwise budget separately. Treat all the prices above as ballpark; error-monitoring vendors reprice often, so verify on the pricing pages before you commit a client budget.
