our call
Start with Optimizely — highest vibe code, weakest moat.
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.
you can rebuild
- In-app custom event tracking and analytics
- First-party web-to-app referral tracking via custom parameters
- Internal LTV and retention cohort reporting
- Push notification conversion triggers
- Basic user journey visualization
what you lose
- Self-Attributing Network (SAN) integration with Meta, Google, and TikTok
- Apple SKAdNetwork postback decoding and conversion value schemas
- Protect360 real-time mobile ad fraud prevention
- OneLink deferred deep-linking across edge cases (iOS/Android store fallbacks)
- Pre-built cost-aggregation APIs across 10,000+ ad networks
real moats
- Certified MMP (Mobile Measurement Partner) status with Meta, Google, TikTok, and Amazon
- Direct integration with Apple SKAdNetwork and Android Privacy Sandbox frameworks
- Device-level fraud detection dataset processed across billions of active installs

Optimizely
Basic A/B split routing is easy to code, but Optimizely's value lies in its sequential statistical engine (which prevents false positives during continuous peeking), WYSIWYG visual DOM editor, edge-side variation delivery, and SOC2 enterprise governance. Rebuilding the visual editor and statistical rigor from scratch is an unnecessary engineering sinkhole.
you can rebuild
- Simple URL-redirect split tests
- Basic client-side JavaScript DOM element swappers
- Simple flag-based feature toggles
- Manual audience segment targeting rules
- Conversion event logging to custom database tables
what you lose
- Stats Engine continuous peeking sequential analysis (mSPRT)
- Marketer-friendly WYSIWYG visual editor with CSS/JS injection
- Zero-flicker edge execution via Cloudflare/Akamai workers
- Multi-armed bandit automated traffic reallocation algorithms
- Enterprise role-based access control, SAML SSO, and audit logs
