EdgeComet Cloud
Custom Caching (CDN + Varnish + Redis)
SaaS Prerendering Cache
Cache Architecture
Built-in multi-layer: fast in-memory + persistent storage. High availability with automatic failover
Multi-layered but requires engineering effort to build and maintain
Provider-managed CDN cache; no visibility into internals
Response Time
<15ms average, consistent across all page types
100-200ms depending on app complexity and cache layer
100-500ms typical; varies by provider and geography
TTL Control
Variable TTL per page type, URL pattern, or content freshness
Manual TTL configuration per cache layer; changes require code deployment
Fixed or limited TTL tiers; typically one setting for the entire site
Auto-Recache
Automatic on bot visit, webhook API, sitemap-based, GSC URLs warning
No automatic recaching; developers must build cache invalidation logic
Basic recache on schedule; limited or no webhook/API integration
Stale Fallback
Serves stale cached version when rendering fails; bots always get content
Depends on custom implementation; requires separate development
Expired cache is discarded; miss triggers re-render with timeout
Cache Analytics
Hit/miss rates, freshness metrics, per-URL status, visual dashboard with trends
No built-in analytics; requires custom logging and external tools
Basic statistics only; no per-URL visibility or trend analysis
Infrastructure Changes
No changes to your application or origin needed
High upfront investment — CDN config, Varnish setup, Redis cluster
No infrastructure changes, but limited to provider's capabilities
Deployment Model
Managed Cloud, self-hosted, or BYOC
Self-hosted only
Cloud-only; your data lives on their servers
Cost
From $99/mo; predictable, no per-request surprises
Multiple hours of developers + infrastructure cost
Per-render pricing that scales unpredictably with traffic
