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

Brands named, in the order the engine gave

1. Sentry mentioned
   Sentry - The default answer, and it's the default for a reason.
2. PostHog mentioned
   PostHog - Worth naming specifically if you're a product-led startup, because error tracking ships inside the same tool as analytics, session replay, and feature flags.
3. Rollbar mentioned
   Rollbar - The one I'd pick if Sentry's pricing model annoys you.
4. Honeybadger mentioned
   Honeybadger - The bootstrapper's choice.
5. Firebase Crashlytics mentioned
   Firebase Crashlytics - If you're mobile-first, just use this.
6. BugSnag mentioned
   BugSnag (SmartBear Insight Hub) - Strong stability-score concept (tracks % of crash-free sessions, which is a better release gate than raw error counts) and a 7.5k/month free tier.
7. Strong mentioned
   BugSnag (SmartBear Insight Hub) - Strong stability-score concept (tracks % of crash-free sessions, which is a better release gate than raw error counts) and a 7.5k/month free tier.
8. GlitchTip mentioned
   GlitchTip - Only if you have a compliance or data-residency reason to self-host.
9. Slack mentioned
   The failure mode for startups isn't picking the wrong tool, it's routing every exception to Slack until the team mutes the channel and stops reading it.

The answer, as recorded

## My picks, in order **1. Sentry** - The default answer, and it's the default for a reason. Best SDK coverage (every language and framework you'd plausibly use), good stack traces with source maps, and it's grown into release tracking, tracing, and session replay so you're not buying three tools. Free tier is 5k errors/month; Team is ~$26/mo for unlimited seats and 50k errors. Unlimited users matters a lot at startup scale - you don't get punished for onboarding engineers. It's also open source, so self-hosting is a real escape hatch if pricing bites later. **2. PostHog** - Worth naming specifically if you're a product-led startup, because error tracking ships inside the same tool as analytics, session replay, and feature flags. One SDK, one bill, generous free tier. The error tracking itself is younger and shallower than Sentry's, but consolidating four vendors into one is a genuinely good trade before Series A. **3. Rollbar** - The one I'd pick if Sentry's pricing model annoys you. Free tier is 25k events/month (5x Sentry's), Essentials starts around $9/mo, and they've folded session replay and AI credits into the base price rather than selling them as add-ons - so the bill scales more predictably. Deploy tracking and automatic grouping are strong. **4. Honeybadger** - The bootstrapper's choice. ~$26/mo bundles error tracking *plus* uptime monitoring and cron/check-in monitoring, which is three line items elsewhere. Especially good if you're a Rails or Elixir shop. Small team, responsive support, no enterprise sales motion. **5. Firebase Crashlytics** - If you're mobile-first, just use this. It's free at essentially any scale and the crash grouping is excellent. The catch is it's mobile-only, so you'll pair it with something above for your backend. **6. BugSnag (SmartBear Insight Hub)** - Strong stability-score concept (tracks % of crash-free sessions, which is a better release gate than raw error counts) and a 7.5k/month free tier. I rank it lower mainly because the SmartBear acquisition has pushed it toward enterprise procurement, which is the opposite of what you want. **7. GlitchTip** - Only if you have a compliance or data-residency reason to self-host. It's Sentry-SDK-compatible, so you can point existing instrumentation at it and swap later with near-zero migration cost. Much thinner feature set - treat it as a hedge, not a first choice. ## What I'd actually do Start on **Sentry's free tier** - it's five minutes to integrate and you'll outgrow the free tier before it costs you anything meaningful. If you're already committed to PostHog for analytics, use its error tracking instead and save yourself a vendor. Revisit at ~$200/mo of spend, which is when self-hosting or Rollbar's pricing curve start to pencil out. One practical note regardless of which you pick: set up **alert filtering on day one**. The failure mode for startups isn't picking the wrong tool, it's routing every exception to Slack until the team mutes the channel and stops reading it.
