What is Sentry Session Replay?
A video-like reproduction of the user session before and around an error — clicks, scrolls, rage-clicks, network & console — tied directly to the error and stack trace. Watch the bug happen.
‘What did you click?’ vs Sentry Session Replay — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | Unprotected / signature email | Session Replay (Sentry) |
|---|---|---|
| Reproduction | ‘What did you click?’ | Watch the session, play it back |
| ‘Can’t reproduce’ | Closed unsolved | See the exact steps to the bug |
| Under the video | Just a screen recording | Network, console, rage-clicks |
| The connection | Replay tool separate from errors | Replay tied to error & stack trace |
| Privacy | Records everything | DOM-based, PII masked by default |
| Frontend + backend | Frontend only | Links to backend errors too |
| The workflow | Switch to an analytics tool | In the developer’s debug view |
| Best fit | (varies) | Session replay for debugging |
Sentry Session Replay is a video-like reproduction of the user session before and around an error — clicks, rage-clicks, network & console — tied directly to the error and stack trace, so you watch the bug and jump to the code. Honest: it’s debugging-first — for deep replay + product analytics, LogRocket/FullStory; for full-stack RUM, Datadog (TechBag sells it). TechBag scopes it & adds GST.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
Record the Session
Sentry reconstructs the DOM rather than recording video, capturing clicks, scrolls, inputs and page changes with the technical detail beneath.
Capture Around the Error
Replay captures the moments before and around an error, including rage-clicks, dead clicks and the failing action.
Underlay the Technical Detail
Beneath the replay sit network requests, console logs and page performance, so you see the failed request at the moment of the click.
Tie to the Error & Stack Trace
A replay links directly to the error and stack trace, so you jump from the exception to the replay, and from the replay to the code.
Protect Privacy
Being DOM-based, it masks sensitive text and inputs, such as PII and payment fields, by default, so private data is not recorded.
Watch what the user saw next to the error behind it — reproduce issues without pulling data from separate tools.
Twelve capabilities. Record, replay, resolve.
Sentry lets you watch what the user did before the error — tied to the stack trace — the frontend-debugging superpower of the Sentry portfolio.
Lightweight DOM Reconstruction
Reconstructs the DOM instead of recording video, so replay is light on the page yet faithful and inspectable.
Privacy Masking by Default
Masks sensitive text and inputs — PII, passwords, payment details — by default, so you debug without recording private data.
Rage-Click & Dead-Click Detection
Flags rage-clicks and dead clicks automatically, the tell-tale signs of a broken or confusing UI.
The Lead-Up to the Error
Captures the steps before and around the error, so you reproduce the bug by watching, not guessing.
Network Requests & Console Logs
Shows the network waterfall and console logs at each moment, linking a click to the failed API call and console error.
Replay Tied to the Error & Stack Trace
Jump from an exception to the replay of the user hitting it, and from the replay to the stack trace and code.
Full Frontend Context
Every replay carries the release, browser, OS, device and affected user: who hit the bug, on what, since which deploy.
Search & Filter Replays
Search replays by URL, error, click target, browser and user to find the sessions with the bug, not scrub through all.
Frontend & Backend Errors Linked
Sentry sees frontend and backend, so a replay can link to the backend error a user’s action triggered.
Replay in Your Debugging Workflow
Replay sits beside your errors, traces and profiles, inside the debugging workflow rather than a separate analytics tool.
Web & Mobile Replay
Covers web and mobile app sessions, so you can watch what a user did before an app crash too.
SaaS or Self-Hosted (FSL)
Run it as SaaS or self-host under the FSL licence, with privacy masking keeping sensitive data out.

Here’s what genuinely sets Sentry Session Replay apart (and where dedicated replay/analytics tools go deeper).
Watch the bug happen — stop guessing how to reproduce it
The hardest frontend bugs are the ones you cannot reproduce: you do not know what the user clicked or in what state. Session Replay plays back the clicks, scrolls, form entries, page changes and rage-clicks before and around the error, so you reproduce by watching instead of asking the user what happened.
Replay tied to the error & stack trace — the differentiator
With a separate replay tool you watch the session, then hunt for the matching error elsewhere. In Sentry, an exception jumps straight to the replay of the user hitting it, and the replay jumps to the stack trace, network waterfall and console error at that moment, so experience and code failure are one click apart.
The technical detail underneath — network, console, rage-clicks
A plain recording shows a click, not that the API call behind it returned a 500. Sentry’s replay aligns the network waterfall, console logs, page performance and rage- or dead-click signals in time with the visual, and its DOM capture is lightweight, with maskable fields.
Debugging-first — and privacy-controllable
Many replay tools serve product teams with funnels and heatmaps. Sentry’s replay is built for debugging, tied to errors, traces and code. DOM-based masking hides sensitive text and inputs by default, and you can self-host under the FSL. For replay plus product analytics, LogRocket and FullStory go deeper.
Developer-loved, self-hostable — and local via TechBag
Sentry (founded 2012) serves 4M+ developers across 100k+ organisations and is self-hostable under the FSL. Self-serve plans bill in USD with 18% GST reverse-charge, and replay volume adds cost. TechBag handles INR/GST, scopes volume and sampling, advises on masking, and compares LogRocket, FullStory and Datadog RUM.
The honest scope
Sentry’s replay is debugging-first and uniquely tied to errors and code. For deeper replay plus product analytics — funnels, heatmaps — LogRocket and FullStory are more specialised; Microsoft Clarity is free and PostHog bundles analytics. Datadog RUM puts replay in a full-stack platform. Replay volume adds cost, so plan sampling.

What could this save you?
Drag the sliders (frontend developers; hour cost as loaded rate). Estimates contrast debugging without replay (asking users what they did, failing to reproduce, closing bugs unsolved) vs Sentry (watch the session, tied to the error and stack trace) — the wins are faster reproduction, fewer ‘can’t reproduce’ tickets, and developer time saved. Illustrative — TechBag scopes your replay volume & cost.
Loaded cost = salary + overheads per productive hour. Illustrative only — your TechBag quote models your actual environment and modules.
