Relyv.ai vs FullStory
Looking for a FullStory alternative or replacement? FullStory is enterprise analytics with a replay tab. Relyv.ai is the AI-native replay platform for engineering teams who actually ship the fix.
They capture pixels. Relyv captures every layer of the same session.

The Relyv Advantage
AI built into the workflow
Intent classifier + frustration scoring — cloud inference on Relyv's own infrastructure for SDK customers (no per-token billing), and on-device in the browser via ONNX/WebGPU when the Relyv extension is installed. No tier gating either way. Every session gets summarised, root-caused, and ticket-drafted automatically.
Engineer-first capture
Network (fetch/XHR/WebSocket/SSE/Beacon), console, DOM, source-mapped stacks, plus 38 distinct event types — front and centre, not buried under analyst dashboards.
Mobile-web + PWA fidelity (native SDKs in alpha)
PointerEvent capture with pressure and tilt, dedicated pinch-zoom recorder, visualViewport keyboard tracking, Service Worker lifecycle, battery + offline transitions. High-fidelity mobile-web replay; native iOS / Android SDKs in alpha.
Self-contained .html export
Every session exports as one offline HTML file with the viewer embedded. Open in any browser without an account — the K-factor mechanic FullStory cannot match without rebuilding the architecture.
MCP-native for AI agents
Claude, Cursor, and Continue call get_session_intelligence as a tool. No other replay platform — including FullStory — exposes session data over MCP.
Published, usage-based pricing
Free 1,000 sessions/mo. Starter $29, Pro $99, Business $399. No annual contracts, no per-seat surcharge, no minimums. Sign up in 60 seconds.
A Closer Look
Where FullStory wins
Mature enterprise analyst tooling — funnels, segmentation, conversion analysis, and a polished dashboard built for non-technical users. Years of compounding network effects on the analytics side.
Where Relyv wins
The engineering workflow. AI that turns a session into a Linear ticket with a Playwright test attached. Stage-vs-prod diff replay. Marketing-tag QA. In-browser PII redaction (regex/Luhn in SDK; ONNX/WebGPU GLiNER with the Relyv extension). MCP-native. Self-contained .html export. Mobile-web parity + native iOS / Android SDKs in alpha. Published pricing.
Mobile gets a 60% bigger lift
Mobile is 60%+ of traffic for most products. FullStory ships native iOS / Android SDKs separately from the web SDK. Relyv's web SDK captures all 38 event types on mobile browsers, plus pen pressure, pinch state, virtual-keyboard show/hide, Service Worker lifecycle — same payload, same viewer, small mobile-vs-web gap on the web SDK alone, and a native iOS / Android SDK (alpha) for teams who need a native install path.
Common Questions
Is Relyv.ai a true FullStory alternative for engineering teams?
Yes. FullStory was designed for product analysts running funnel and segmentation reports — replay was a feature added later. Relyv.ai inverts that: replay + AI workflow are the core, and the analytics dashboard sits on top. Engineers get network, console, source-mapped stacks, and an AI repro recipe out of the box.
How does Relyv.ai's AI compare to FullStory's AI?
FullStory ships isolated AI features (signals, summaries) gated behind enterprise tiers. Relyv.ai bakes AI into every session at every tier — auto-summary, auto-repro, auto-ticket, and auto-Playwright-test, with a fixed monthly AI budget per plan (no surprise per-token bills).
Can I run Relyv.ai side-by-side with FullStory during a migration?
Yes. Our SDK is a single <script> tag and coexists with FullStory during your evaluation or migration period — same DOM, no observed conflicts. Most teams retire FullStory after 30–60 days.
How does Relyv.ai's pricing compare to FullStory's?
FullStory uses quote-based enterprise pricing — annual contracts, sales-led, opaque session quotas. Relyv.ai is published, usage-based, monthly-cancellable: Free (1k sessions), Starter $29, Pro $99, Business $399, Enterprise on request. Sign up in 60 seconds, no sales call.
Does Relyv.ai support data residency the way FullStory does?
Yes — EU + US regions, with data pinned at the workspace level. PII is masked in-browser via 12-category regex + Luhn validation in the SDK (plus ONNX/WebGPU GLiNER deep-scan when the Relyv extension is installed) before any data leaves the browser. SOC 2 Type II in progress; full DPA on request.
Can I export FullStory recordings into Relyv.ai?
FullStory recordings are stored in their proprietary format and aren't portable. Run Relyv.ai alongside FullStory during the migration window so you build a full Relyv.ai history (including AI summaries) that wasn't possible inside FullStory.
Does Relyv.ai integrate with bug trackers like Linear, Jira, GitHub?
Bi-directionally with 14 trackers: Linear, Jira, GitHub, GitLab, Asana, ClickUp, Trello, Notion, Slack, Teams, Discord, HubSpot, Salesforce, and email. One click pushes a Relyv replay with the AI-drafted repro, console + network evidence, and a Playwright test attached. Status changes flow back into Relyv. FullStory exports links only.
Does Relyv.ai work with Salesforce / HubSpot like FullStory does?
Natively. HubSpot creates a ticket pre-filled with the AI bug report + session evidence; Salesforce creates a Case attached to the same data. Both ship as first-class providers in gt-relyv-integrations alongside the bug trackers — no third-party Zapier hop.
How does mobile coverage compare to FullStory's native SDKs?
FullStory ships separate iOS and Android SDKs that don't share a feature surface with their web SDK. Relyv's single web SDK captures all 38 event types on mobile browsers — PointerEvent with pen pressure and tilt, pinch-zoom gesture state, virtual-keyboard show/hide via visualViewport, Service Worker lifecycle, Battery API, online/offline transitions. Same payload, same viewer for web sessions; native iOS / Android SDKs in alpha emit into the same viewer.
Can my AI agent query Relyv sessions?
Yes — Relyv is MCP-native. Claude, Cursor, and Continue call get_session_intelligence as a tool, ask "what frustrated the user in session X", and get structured intent + frustration + outcome data back. FullStory does not expose session data over MCP today.
Can I share a Relyv recording without a viewer account?
Yes. Every session can export as one offline .html file with the viewer embedded inline — DOM, network, console, AI summary, and 38 event types replay in any browser without an account or internet. FullStory recordings are gated behind a FullStory login.
