Feature Suite
Engineered for Speed, Precision & Scale
Everything traditional shorteners do, rebuilt with modern edge infrastructure and developer ergonomics.

Sub-5ms p99 Redirect Latency
Legacy shorteners take 150ms to 400ms to resolve a single redirect because they perform synchronous disk writes and execute heavy tracking scripts. TrimMe uses Go Fiber with fasthttp and a tiered in-memory caching topology:
- ✓ L1 Cache (In-process RAM): 0.05ms lookup for top 5,000 links
- ✓ L2 Cache (Redis 7.x): 0.8ms lookup across entire link catalog
- ✓ PostgreSQL 16: Query only on cold cache miss with instant auto-warming
BENCHMARK (oha 10k req/s) PASSED
Latency 50%: 0.82 ms
Latency 90%: 1.94 ms
Latency 99%: 3.12 ms
Throughput: 48,210 req/sec
Rule Evaluation Order (Priority):
1. Device Rule (Mobile / iOS) apps.apple.com/...
2. GeoIP Rule (Country: DE / Germany) mybrand.com/de
3. A/B Split (30% Variant B) mybrand.com/landing-b
4. Default Target (Fallback) mybrand.com
🎯
Contextual Smart Routing
Why force iOS users into a web browser or show Spanish users English content? TrimMe evaluates incoming HTTP headers in real-time without introducing redirect delay:
- ✓ Device Type: Deep link to App Store, Play Store, or Web
- ✓ GeoIP Country: MaxMind MMDB and Cloudflare country resolution
- ✓ Language & Referrer: Match Accept-Language or incoming traffic source
- ✓ Deterministic A/B Splits: Consistent hashing on IP + slug
📊
Async Telemetry & Privacy
Track impressions, click trends, unique visitors, and top devices with zero impact on user experience:
- ✓ Redis Streams (XADD): Non-blocking async event publication
- ✓ Daily Rollup Aggregates: Instant charts via pre-aggregated SQL tables
- ✓ Zero Cookies: 100% GDPR, CCPA, and PECR privacy compliance
