our call
Start with FullStory — highest vibe code, weakest moat.
FullStory
Wrapping rrweb into a web app takes a few days, but storing millions of DOM diffs without killing client performance or ballooning cloud database bills requires serious infrastructure engineering. Client-side PII masking, SOC2 compliance, and fast event indexing cannot be prompt-engineered.
you can rebuild
- Client-side DOM event and mutation recording
- Basic session replay video playback
- Console logs and network request capturing
- Simple click and scroll heatmaps
- Basic funnel step tracking
what you lose
- Automated client-side PII and sensitive input field masking before data transmission
- Instant retroactive search over unindexed DOM text and element CSS selectors
- Frustration heuristics like rage clicks, dead clicks, and error clicks
- Enterprise compliance certifications including SOC2 Type II, HIPAA, and GDPR tooling
- High-throughput event ingestion infrastructure optimized for gigabytes of raw DOM diffs
real moats
- Patented client-side DOM capture and event compression engine
- Proprietary retroactive search index over raw DOM mutation streams
- SOC2 Type II, HIPAA, and strict client-side PII masking guarantees
open source escape hatches
- PostHog MIT
- OpenReplay Apache-2.0
- rrweb MIT
Wayflyer
You can easily build the marketing dashboard and ROAS aggregator in a weekend. However, Wayflyer is a capital provider, not just a software vendor. You cannot prompt-engineer institutional debt facilities, credit underwriting, or debt collection infrastructure.
you can rebuild
- Multi-channel ad spend aggregation dashboard
- Blended ROAS and blended CAC metrics calculations
- Daily store sales and refund tracking
- SKU-level gross margin visualization
- Inventory reorder stockout forecasting
what you lose
- Access to non-dilutive inventory financing lines
- Flexible daily revenue-proportionate debt repayment schedules
- Institutional underwriting and credit risk assessment
- Merchant performance benchmarking against industry datasets
- Direct bank rails integration for automated repayments
real moats
- Multi-hundred-million-dollar institutional debt facilities
- Proprietary credit default risk models trained on historical merchant performance
- Lending regulations and financial compliance frameworks across regions
