Relyv.ai vs Gainsight PX
Gainsight PX is a product-analytics + in-app-engagement platform optimised for customer success teams. Relyv.ai is an engineering-grade session replay platform with the same in-app feedback surface, plus DOM + network + console + AI bug reports + 14 tracker integrations. Pick Relyv when "what users did" needs to lead directly to "what we ship to fix it".
They capture pixels. Relyv captures every layer of the same session.
| Feature |  | Gainsight PX |
|---|---|---|
| Session Replay (DOM)Relyv's replay is DOM-level + searchable; Gainsight PX positions replay as a supplemental signal next to analytics. | Pixel-accurate DOM serialisation | Available, optional add-on |
| Console + Network CaptureGainsight PX captures product-analytics events, not technical-state. | fetch/XHR/WebSocket/SSE/Beacon + console.log/info/warn/error/debug | No |
| AI Session SummaryRelyv summarises individual sessions (cloud, or on-device with the Relyv extension); Gainsight's AI lives in the aggregate analytics layer. | Every session, session-level | AI features in analytics layer |
| Auto Bug Reports → TicketsLinear, Jira, GitHub, GitLab, Asana, ClickUp, Trello, Notion, Slack, Teams, Discord, HubSpot, Salesforce, email. | 14 trackers, pre-filled | Custom CRM workflows |
| Playwright Test GenerationReplay → runnable spec in one click. | Yes | No |
| In-App Engagements (Tooltips, Surveys, NPS)Gainsight's flagship strength; Relyv covers the same use cases at base depth. | Surveys + feedback widget + tags-on-elements | Mature in-app engagement engine |
| Funnels + Retention CohortsGainsight is more polished on classical product-analytics; Relyv's flows are headless-Chrome scheduled paths. | Funnel builder + Flows + Segments microservices | Mature funnels + retention dashboard |
| Frustration Detection | Rage + dead + scroll-thrash + error-burst, MLP-scored | Not documented |
| Cross-Session Heatmaps | Workspace-aggregated click + scroll | Click maps via add-on |

| Mobile Touch + Pinch + Virtual Keyboard | PointerEvent + visualViewport | Native mobile SDK separate |
| Self-Contained .html Export | Single offline file w/ embedded viewer | No |
| CRM IntegrationsGainsight's parent suite is a CS platform; Relyv ships first-class CRM connectors but isn't a CS platform. | HubSpot + Salesforce native | Native Gainsight CS workflow |
| MCP-Native (Claude / Cursor) | Yes | No |
| PII Masking | On-device Luhn + 12-category regex (SDK); + ONNX/WebGPU GLiNER with the Relyv extension | Server-side controls |

The Relyv Advantage
Engineering-grade replay, not a CS dashboard
Gainsight PX is part of a customer-success suite optimised for renewals and adoption. Relyv is an engineering platform — full DOM replay + 5-protocol network capture + console with stack traces + AI bug reports — for teams whose job is to ship the fix.
AI is a session-debugging layer, not an analytics layer
Intent classification, frustration scoring, session summary, AI bug report, Playwright test generation. Cloud inference on Relyv's own infrastructure for SDK customers — no per-token billing surfaced. When the Relyv browser extension is installed, the same inference shifts on-device via ONNX/WebGPU in an offscreen document — zero cloud GPU cost, zero data leaving the browser.
14 tracker + 2 CRM integrations, native
Linear, Jira, GitHub, GitLab, Asana, ClickUp, Trello, Notion, Slack, Teams, Discord, HubSpot, Salesforce, email — each ticket pre-filled with the AI repro, console + network evidence, and a Playwright spec. Bi-directional sync.
Mobile-web + PWA fidelity (native SDKs in alpha)
PointerEvent with pressure + tilt, pinch-zoom recorder, visualViewport keyboard tracking, Service Worker lifecycle, Battery + offline transitions — web SDK today; native iOS / Android SDKs in alpha.
Self-contained .html export
Every session exports as one offline HTML file with the viewer embedded inline. K-factor virality Gainsight PX does not offer.
Published, usage-based pricing
Free 1,000 sessions/mo. Starter $29. No annual contracts, no per-seat surcharge, no sales call required. Gainsight is quote-based and sales-led.
A Closer Look
Where Gainsight PX wins
Mature product-analytics + in-app-engagement workflows tied into the broader Gainsight customer-success suite (CS, CC, Renewal Intelligence). If your buying motion is CS-led and the value is "the CSM saw the customer struggling in PX and triggered a tooltip + an account email", Gainsight is the right tool.
Where Relyv wins
When the value chain ends at "an engineer ships the fix" rather than "a CSM triggers a play". Full DOM + network + console capture, AI-drafted Linear/Jira tickets, Playwright test generation, in-browser PII redaction (regex/Luhn in SDK; ONNX/WebGPU GLiNER with the Relyv extension), 14 tracker + 2 CRM integrations, MCP-native, self-contained .html export, published usage-based pricing.
When to use both
Many teams run Gainsight PX for the CS / renewals story and Relyv for the engineering / RCA story. SDKs do not conflict — they capture different signal layers (analytics events vs. full session DOM/network/console). Gainsight PX answers "is this account engaging"; Relyv answers "what broke for this user".
Common Questions
Is Relyv.ai a Gainsight PX alternative for engineering + product teams?
For the engineering side, yes — Relyv is built for it. For the customer-success side, Gainsight PX is purpose-built and remains the right tool. Many teams run both: Gainsight for renewals + adoption, Relyv for the bug-fix workflow. The SDKs do not conflict.
How does Relyv's AI compare to Gainsight PX's AI?
Gainsight's AI runs cloud-side as an analytics layer (predictive churn, adoption scoring). Relyv's AI is a session-debugging layer — intent classification, frustration scoring, session summary, AI bug report drafting, Playwright test generation. Cloud inference on Relyv's own infrastructure for SDK customers (no per-token billing surfaced); on-device via ONNX/WebGPU when the Relyv browser extension is installed. Different jobs, different deployment models, different cost structures.
Can I use Relyv with my existing CRM (Salesforce / HubSpot) the way Gainsight does?
Yes. 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 12 tracker integrations. Note that Gainsight's CRM story is broader (renewal + health-score sync); Relyv's is focused on engineering-evidence ticket creation.
Does Relyv ship in-app engagements (tooltips, surveys, NPS) like Gainsight PX?
Relyv ships an in-session surveys widget and a feedback widget, plus the in-extension triage UI. Both run via shadow-DOM injection and integrate with the session timeline. Gainsight PX's engagement engine is more mature on tooltip-walkthrough mechanics; Relyv's is more mature on session-context-aware feedback capture.
How does Relyv handle data privacy compared to Gainsight PX?
PII is masked on-device 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. EU + US data residency available. SOC 2 Type II in progress. Gainsight is SOC 2 Type II certified and handles enterprise CS workflows; both meet the bar for regulated industries but with different trust models.
Can I share a Relyv recording with someone who has no account?
Yes. Every session can export as one offline .html file with the viewer embedded inline — DOM, network, console, AI summary, and all 38 event types replay in any browser, no account, no internet. Gainsight PX recordings live behind a Gainsight account.
Does Relyv expose session data to AI agents the way Gainsight does not?
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. Gainsight does not expose session data over MCP today.
How does Relyv's pricing compare to Gainsight PX's?
Gainsight PX is quote-based enterprise pricing with annual contracts and a sales-led motion. Relyv publishes prices: Free 1,000 sessions/mo, Starter $29, Pro $99, Business $399, Enterprise on request. Sign up in 60 seconds, monthly-cancellable, no per-seat surcharge.
