How Sentry helps
Session Replay
Replay user sessions to visually debug issues.
Private by Default
Sessions prioritize user privacy.
Associated Errors and Performance
Link replays to error and performance issues.
Hydration Error Diff Tool (EA)
Pinpoint hydration errors through session replays.
Rage & Dead Click Detection
Identify unresponsive elements users engage with.
Loading image for Debug with visual context media
Loading image for Protect your users' privacy media
Loading image for Fix mobile issues without the guesswork media
Visual Debugging for Developers
Navigate your application’s console output, network calls, and even watch reproductions of user actions. Get the insights and context that matters, right inside Sentry.
Lock down your debugging experience without sacrificing user privacy with a range of privacy controls to ensure no sensitive user information leaves your users device.
Maintain a 5 star mobile app experience by getting device-level insight into a given user session including battery level, device orientation, and connectivity.
Session Replay has been instrumental in helping us resolve hydration errors. With Replay, we can visually see the jankiness of the page and pinpoint which components were impacted, saving us hours of manual debugging.

I have been using Session Replay in a few of my company's apps and it is a really great feature! Not only has it helped me and my team to be more efficient on resolving very oddly-specific issues and things related to UI, but also has helped me spot issues with non-error sessions as well.

Getting started with Sentry is simple
We support every technology (except the ones we don't).
Get started with just a few lines of code.
Install
The Replay integration is already included in your browser or framework SDK NPM packages. If you’re using CDN bundles instead of NPM packages, you need to load the Replay integration CDN bundle in addition to your browser bundle:
Click to Copy
npm install --save @sentry/browser
Set Up
To set up the integration, add the following to your Sentry initialization. There are several options you can pass to the integration constructor. See the configuration documentation for more details.
Click to Copy
// import Sentry from your framework SDK (e.g. @sentry/react) instead of @sentry/browser import * as Sentry from "@sentry/browser"; Sentry.init({ dsn: "https://examplePublicKey@o0.ingest.sentry.io/0", // This sets the sample rate to be 10%. You may want this to be 100% while // in development and sample at a lower rate in production replaysSessionSampleRate: 0.1, // If the entire session is not sampled, use the below sample rate to sample // sessions when an error occurs. replaysOnErrorSampleRate: 1.0, integrations: [ Sentry.replayIntegration({ // Additional SDK configuration goes in here, for example: maskAllText: true, blockAllMedia: true, }), ], });
Session Replay supports all browser-based applications. This includes static websites, single-page-applications and also server-side-rendered, that includes frameworks such as: Django, Spring, ASP.NET, Laravel, Express and Rails.

FAQs
Sentry’s Session Replay provides a video-like reproduction of user interactions on a web or mobile app, giving developers the details they need to resolve errors and performance issues faster. All user interactions - including page visits, mouse movements, clicks, and scrolls - are captured, helping developers connect the dots between a known issue and how a user experienced it in the UI.
Session Replay is available for web-based and mobile applications. It supports all web applications whether it’s static or dynamic, server-side rendered or single-page applications.
It is built to work with @sentry/browser, and our browser framework SDKs:
Vue
This means Session Replay is supported on server-side rendered Web applications such as Express, Laravel, Rails, Django, ASP.NET, Spring Boot and others. We recommend creating a separate project in Sentry to track frontend errors from your backend. And adding Session Replay to your frontend via npm, or using the loader.
Session Replay for mobile supports the following SDKs:
Session Replay has minimal impact on the performance on your web application. We employ standard optimizations such as data compression, which is performed in a web worker outside of the browser’s UI thread in such a way that minimizes impact on your application. You can measure the overhead of Session Replay on your application without deploying to production by following these instructions.
We offer a range of privacy controls to ensure that no sensitive user information leaves the browser. By default, our privacy configuration is very aggressive and masks all text and images, but you can – for example – choose to just mask user input text. More on that can be found in our documentation. We also provide server-side scrubbing to additionally filter on the server in case anything slips by.
Additionally, we offer a self-serve deletion capability of individual replays in the UI.
Session Replay adheres to the same security standards and is subject to the same compliance requirements as all of our software. Please see our Security page for further details.
Please check out our pricing page for details.
You will be able to set up Session Replay with only a few lines of code. Your existing @sentry/browser basic setup + DSN can be used for configuration.
