Sentry catches the error. GlitchReplay catches the error and records the session that caused it — on every plan, flat-rate, no per-replay metering. And because we're Sentry-SDK compatible, switching is a one-line DSN change.

Sentry is excellent at error tracking — it built the category. But the bill is metered: events and session replays are billed pay-as-you-go on top of your plan, and a busy app can blow through its replay quota in days. Replay is the thing you reach for most when an error is hard to reproduce, and it's the line item that scales against you.
To get the full debugging picture you often end up running two products — an error tracker and a separate session-replay tool — and paying two subscriptions to see one bug. GlitchReplay folds both into one flat-rate plan, with every session recorded so the replay is already there when the error fires.
An honest comparison. Sentry wins on breadth; GlitchReplay wins on bundling errors and replay into one simple, flat-rate tool.

Sentry pricing and features as published on sentry.io; verify current figures there before deciding. GlitchReplay pricing reflects our published plans.
Error tracking and session replay in a single product. No bolting a separate replay tool onto your error tracker and reconciling two bills to debug one issue.
Pro is $49/mo with unlimited events (rate-limited for abuse, not billing). No pay-as-you-go event meter and no surprise replay overages at the end of the month.
Every session is recorded — even on the free tier. When an error fires, the session that caused it is already saved, so the replay is waiting when you open the issue.
GlitchReplay speaks the Sentry SDK protocol. Keep @sentry/nextjs, @sentry/react, or @sentry/node and change one DSN — no instrumentation rewrite.
You already have the SDK installed. Migration is configuration, not a rewrite.
No new package to install. GlitchReplay is Sentry-SDK compatible — @sentry/nextjs, @sentry/react, and @sentry/node all work unchanged.
Replace your Sentry DSN with the GlitchReplay DSN from your project settings. That's the migration. Redeploy and events flow to GlitchReplay.
Point your existing source-map upload step at GlitchReplay and minified production frames resolve to original file, line, and function.
For error tracking on web apps, effectively yes. GlitchReplay is Sentry-SDK compatible — you keep @sentry/nextjs, @sentry/react, or @sentry/node and just point the DSN at GlitchReplay. You get grouped issues, stack traces, breadcrumbs, and source-map resolution. Note that Sentry covers far more languages and platforms than we do (90+ SDKs, mobile, native, backends in many languages); if your stack needs that breadth, Sentry is the better fit.
Sentry meters errors and replays separately on a pay-as-you-go model, and session replay is billed per replay on top of your plan — which can climb quickly on a busy app. GlitchReplay is flat-rate: Pro is $49/mo with unlimited events (rate-limited for abuse, not billing) and session replay included on every tier, including free.
Yes. Every session is recorded on every GlitchReplay plan, including free. When an error fires, the full session that produced it is already saved. Sentry includes a small replay quota and bills additional replays as metered usage on top of your plan.
Yes. Upload your .js.map source maps at deploy time and GlitchReplay resolves each frame back to the original file, line, and function — the same workflow you already use with Sentry.
Sentry has far broader language and platform coverage (90+ SDKs spanning JavaScript, Python, Go, Ruby, Java, .NET, mobile, and native), a large integrations marketplace, and a mature performance/tracing product. GlitchReplay is focused on web app error tracking plus session replay in one flat-rate tool. If you need polyglot backend coverage or deep distributed tracing, Sentry is the stronger choice.
