our call
Start with Amplitude — highest vibe code, weakest moat.
Amplitude
Building a basic event logger and UI takes a few hours, but reproducing Amplitude's query speed across billions of unaggregated events is an infrastructure nightmare. You will sink months into managing ClickHouse clusters, handling session stitching, and tuning DB performance.
you can rebuild
- Basic funnel drop-off calculation across sequential event steps.
- Client-side JavaScript event capturing for pageviews and button clicks.
- Simple user retention charts (Day 1, Day 7, Day 30 retention).
- User timeline viewing showing event sequences for specific IDs.
- Basic cohort segmentation based on static event properties.
what you lose
- Sub-second response times on dynamic, unstructured behavioral cohort queries.
- Automated cross-device identity resolution and retroactive user merging.
- Self-serve UI for non-technical product managers, requiring SQL for custom queries.
- Native sync capabilities with Snowflake, BigQuery, and enterprise CDPs.
- Enterprise-grade SLAs, SOC2 Type II compliance, and GDPR data erasure automation.
real moats
- Proprietary distributed columnar database architecture optimized specifically for non-linear behavioral graph queries.
- Decade of battle-tested SDK performance to prevent blocking client UI execution on slow networks.
- Deep ecosystem integrations with CDP platforms (Segment, RudderStack) and data warehouses (Snowflake, Databricks).
- Data governance, taxonomy controls, and automatic anomaly detection tools built for cross-functional teams.
AppsFlyer
AppsFlyer's core value is its Mobile Measurement Partner (MMP) status with Meta, Google, TikTok, and Snap, along with native SKAdNetwork / Privacy Sandbox implementations. Building a custom event ingestion pipeline is straightforward, but independent developers cannot obtain raw install attribution payloads directly from self-attributing networks.
