Pick a scale or set your usage. Each tool shows its cheapest plan for it, cheapest first, with the arithmetic and the vendor's pricing page. Price is one input — which one fits your situation matters as much.
PostHogPay-as-you-go$0/moWithin the free allowanceBilled per ingested $exception event, with graduated rates from posthog.com/docs/error-tracking/pricing — free to 100k, $0.00037 to 325k, $0.00014 to 10M, $0.000115 beyond. The Free plan needs no card but is limited to the free allowance; pay-as-you-go has no base fee.
GlitchTipSmall$15/mo$15 planHosted plans. Events also count uptime checks, performance transactions and release-file storage, not just errors. Over quota, GlitchTip throttles gradually and blocks fully at 2× — there's no overage billing. Annual billing discount on request. Open source and free to self-host (server costs yours).
HoneybadgerTeam$26/mo$26 planOverage billing is opt-in; without it Honeybadger processes up to 125% of your quota, then stops. Larger error tiers are available through the plan calculator (not modeled — at high volume a bigger plan may be cheaper than overage). Business ($80/mo, 50K errors, $0.0006 overage) adds compliance and SSO. Annual billing is $286 (Team) / $880 (Business) per year. Developer is one user only.
RollbarEssentials 50k$29/mo$29 planPrices from Rollbar's machine-readable pricing page (rollbar.com/pricing-for-agents/, generated July 8, 2026), billed monthly; annual billing is 2 months free. Each overage rate is the step's price ÷ its occurrences, the 'plan's same flat per-event rate' Rollbar describes — derived, not a published number. Occurrences are taken as errors. Advanced (from $13/month at 10k up to $12,049 at 50M, with 180-day retention and adaptive alerts) costs more at every volume and is left out. Above 80M events a month is Enterprise (contact sales). Rollbar never charges per seat.
SentryTeam$29/mo$29 planTeam is $29/mo billed monthly ($26/mo annual) with 50k errors included; overage uses pay-as-you-go rates from docs.sentry.io/pricing — $0.0003625 to 100k, $0.0002188 to 500k, $0.0001875 to 10M, $0.0001625 to 20M, $0.00015 beyond. Reserving volume in advance is about 20% cheaper. Developer is one user only. Business ($89/mo, $80 annual) has higher per-error rates.
Read from each vendor's pricing page (oldest check 2026-10-03). The model is plan fee + usage beyond what's included × the vendor's rate; volume discounts, annual billing, taxes and regional prices are left out — see each tool's notes. Always confirm on the vendor's page before you commit.
