Find missing invalidation, no TTL, cache stampedes, Redis misuse, architecture gaps, and security hygiene issues — before they corrupt production data.
Missing invalidation. No TTL. Cache stampedes on every deploy. KEYS * in production bringing Redis to its knees. When the stale data hits customer-facing pages, it started here.
90 checks across 6 categories, covering every aspect of caching logic and data consistency.
Detects database writes without cache invalidation, stale cache after mutations, missing cache-aside pattern implementation, and write-through inconsistencies that corrupt user-facing data.
Catches cache.set() without TTL, infinite expiration on volatile data, inconsistent TTL across related keys, and missing expiry policies that let stale data accumulate forever.
Finds cache misses without distributed locks, thundering herd on popular keys, missing singleflight patterns, and cold-start scenarios that hammer your database on every deploy.
Detects KEYS * in production, unbounded hash growth, missing connection pooling, large key serialization, and dangerous FLUSHALL calls that nuke your entire cache layer.
Catches N+1 cache lookups in loops, missing multi-tier caching, no cache warming strategy, over-caching of frequently-changing data, and cache key collisions across services.
Detects sensitive data cached without encryption, PII in cache keys, missing access controls on shared caches, cache poisoning vectors, and unprotected cache endpoints.
Choose the plan that matches your caching requirements.
