Install Relyv.
The 14 KB SDK records every session on the site you own. The browser extension records any website you visit. The desktop app records everything else — Figma, Xcode, terminals, video calls, multi-monitor.

From install to insight in minutes.
Every install — SDK, extension, desktop — streams the same DOM-accurate replay into the same dashboard.
- 01
Install in 30 seconds
Paste one script tag, click Add to Chrome, or download the desktop app. Pick any of the three above — the rest of the flow is identical.
- 02
Sessions auto-record
DOM, network, console, errors stream in real time. PII is masked on device before bytes leave the browser. <1% perf overhead.
- 03
AI surfaces the signal
Frustration scoring, funnels, alerts, AI summaries, churn prediction. Replays open with one click; Slack, Linear, Jira tickets file themselves.
Pick by what you want to record.
Your own product
Sites and apps you control — the SDK auto-records every visitor and turns on the full AI analytics layer.
Any other website
A competitor, a vendor portal, a customer's site during a support call — the extension records any URL without code.
Apps the browser can't reach
Figma, Xcode, terminals, video calls, multi-monitor walkthroughs with system audio and webcam overlay.
What each install gives you
The SDK is the analytics product. Extension and Desktop are recording tools.
Before you install.
Which install do I need?
SDK if you own the site — it's the only one that unlocks the full analytics stack (frustration, funnels, alerts, AI). Chrome Extension if you want to record a site you don't control. Desktop App if you need to record apps the browser can't reach, like Figma or terminals.
Will the SDK slow my site down?
14 KB gzipped, loaded async, <1% perf overhead measured against Lighthouse + Web Vitals on real sites. No render blocking, no main-thread stalls. Customers report no perceivable difference.
How is PII handled?
Every input, password field, and any element you mark sensitive is masked on device before bytes leave the browser. We never see raw PII. GDPR + CCPA aligned, SOC 2 in progress. You can also self-host the ingest endpoint if your DPO requires data residency.
How much does it cost?
Free to start — generous session quota for solo devs and small teams. Paid plans add AI insights, predictive churn, SSO, and longer retention. See pricing →
Do I have to install all three?
No — start with whichever fits today and add the others later. The SDK on your own product is the highest-leverage install. Most teams add the extension second for QA + support, and the desktop app for product demos and bug-bashing.
Where does my data live?
Default: Google Cloud us-central1 with regional pinning available (asia-south1 for India, europe-west1 for EU). Enterprise customers can request EU-only or self-hosted ingest. See our DPA for the full processor list.
Ready to record your first session?
Pick a path. You can add the others later — they all share the same dashboard.

Browser extension
Record any website you can visit, without touching its code. Same DOM + network + console fidelity as the SDK on the wire, played back in the same viewer.
Any website the SDK isn't on
- QA on staging without redeploying
- Customer-bug capture during a support call
- Competitive research — replay how a competitor's flow works
- Internal admin tools you can't add JavaScript to
Show analytics on captured sessions
No frustration scoring, no funnel analytics, no real-time alerts, no AI summaries on extension recordings — those need a verified domain, which only the SDK install provides. You still get full DOM + network + console replay.
Desktop app
Native recorder for macOS, Windows, Linux. Records any website plus whatever else is on your screen — desktop apps, terminals, design tools, video calls, multi-monitor flows. Pairs system audio + webcam into a single replay.
The browser can't reach it
- Native apps — Figma, Sketch, Xcode, Postman, terminals
- Multi-monitor walkthroughs that span screens
- System audio (the extension can't access it)
- Webcam + screen overlay for product demos and async standups
Recorder only
No frustration scoring, no funnel analytics, no real-time alerts on desktop recordings. That's the SDK's job — it needs a verified domain and the auto-recorder to know what "normal" looks like.
