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

Brands named, in the order the engine gave

1. per-seat mentioned
   The two things that matter most are unlimited projects and per-seat or flat pricing instead of per-project pricing.
2. Sentry mentioned
   Sentry - the default, and the right default.
3. GlitchTip recommended
   GlitchTip - the cost play, and my pick if you're fee-sensitive or privacy-constrained.
4. Honeybadger mentioned
   Honeybadger - pick this if predictable billing matters more than breadth.
5. Ruby mentioned
   Strongest on Ruby/Rails and Elixir shops.
6. Rollbar mentioned
   Rollbar - strong grouping and deduplication, which is its real differentiator when you're triaging across many apps and don't want the same root cause filed eleven times.
7. PostHog mentioned
   PostHog - only if you already run PostHog for analytics.

The answer, as recorded

# Error monitoring for agencies The agency problem is different from the single-product problem: you have many small projects rather than one big one, and your cost model has to survive that. The two things that matter most are **unlimited projects** and **per-seat or flat pricing instead of per-project pricing**. Here's what I'd actually use, in order. **1. Sentry** - the default, and the right default. Team plan is ~$26/mo (annual) for 50k errors with *unlimited projects and unlimited team members*, which is exactly the shape an agency needs: spin up a project per client at no marginal cost and pool the event quota across all of them. Broadest SDK coverage (every frontend/backend/mobile stack you'll touch), and release tracking ties an error to a specific commit and deploy - valuable when you're context-switching between eight codebases and need to know *which* client's Thursday deploy broke. Caveat: pooled quotas mean one noisy client can eat the allowance, so set per-project spend caps and inbound filters early. **2. GlitchTip** - the cost play, and my pick if you're fee-sensitive or privacy-constrained. Drop-in Sentry-SDK compatible: change the DSN and your existing `@sentry/*` instrumentation works untouched, so it's a cheap experiment and a cheap exit. Unlimited projects and team members, hosted plans are inexpensive, or self-host for roughly $5-10/mo of infrastructure. Worth knowing: self-hosting *Sentry* proper is a genuinely heavy lift (Kafka, ClickHouse, Snuba), which is the main reason GlitchTip exists. Tradeoff is a thinner feature set - fewer integrations, less performance tooling. **3. Honeybadger** - pick this if predictable billing matters more than breadth. Flat monthly pricing from ~$29 rather than event-metered, which means no surprise overage the month a client's cron job loops. Error tracking plus uptime and cron monitoring in one bill, covering a lot of what agencies otherwise buy separately. Strongest on Ruby/Rails and Elixir shops. **4. Rollbar** - strong grouping and deduplication, which is its real differentiator when you're triaging across many apps and don't want the same root cause filed eleven times. Free tier at 25k events/mo, paid roughly $21-82/mo. Good middle option if Sentry's interface feels heavy to you. **5. PostHog** - only if you already run PostHog for analytics. Then exception tracking is free up to 100k events/mo, the most generous tier in this category, and you avoid a second vendor and a second login. Don't adopt PostHog *for* error monitoring; adopt it for product analytics and take errors as a bonus. **Bugsnag I'd skip for agency use.** Pricing runs $59-$499/mo with an unlimited tier at $999, and the free tier is capped at a single user - the economics assume one well-funded product team, not a portfolio of small projects. ## One thing to decide up front How clients get visibility. None of these are genuinely white-label, and I couldn't confirm agency-specific multi-tenant features for GlitchTip - their docs or sales would need to answer that. The realistic patterns are: keep monitoring entirely internal and surface errors in your own client reports, or add clients as members on their own project (clean on Sentry, where seats are unlimited on Team). If a client ever offboards, project-per-client structure also makes handing over or deleting their data straightforward - worth setting up that way from day one rather than retrofitting it.
