Is Cachee a Readyset replacement?

Cachee replaces Readyset for teams that need to cache more than SQL queries. Readyset only caches Postgres/MySQL query results. Cachee caches any data — key-value pairs, JSON, sessions, API responses, computed results — at 31ns with AI-powered pre-warming. For SQL-only workloads, Readyset's automatic write-through invalidation is a unique advantage.

How much faster is Cachee than Readyset?

Cachee L1 cache hits resolve in 31ns from in-process memory. Readyset's query proxy typically adds ~1ms to cached queries. Cachee is approximately 500,000x faster for cached reads. More importantly, Cachee caches any data type — not just SQL results.

Can Readyset cache API responses or session data?

No. Readyset only caches SQL query results by intercepting the Postgres or MySQL wire protocol. It cannot cache API responses, session tokens, rate limits, feature flags, computed results, or any non-SQL data. Cachee handles all of these via the RESP protocol at 31ns with AI optimization.

How much does Readyset cost compared to Cachee?

Readyset Cloud pricing varies but a production deployment costs approximately $300+/month for the query proxy instance plus storage for materialized views. This only covers SQL caching. Cachee's Scale plan is $149/month and caches any data type with AI optimization — 50% less for broader coverage.

Can I use Cachee with Readyset?

Yes, though they serve different layers. Readyset sits between your application and database, caching SQL query results. Cachee sits at the application layer, caching KV data, sessions, API responses, and computed results. Using both gives you automatic SQL caching (Readyset) plus universal application caching (Cachee).

Does Readyset have CDC auto-invalidation?

Readyset has write-through invalidation for SQL queries it proxies, but only for Postgres and MySQL. It cannot invalidate non-SQL cache keys or watch arbitrary database changes. Cachee's CDC auto-invalidation works with any database WAL and invalidates any cache key type in under 1ms — not limited to SQL results.

Does Readyset support cache contracts?

No. Readyset materializes SQL query results but provides no per-key SLA enforcement, compliance audit trails, or contractual freshness guarantees on cached data. Cachee's cache contracts let you define per-key SLAs that are SOC 2, FINRA, and HIPAA auditable.

Does Readyset have a causal dependency graph?

Readyset tracks SQL query dependencies internally for its materialized views, but this is limited to SQL tables and cannot express arbitrary cache key relationships. Cachee's causal dependency graph uses DEPENDS_ON declarations for any cache key, enabling automatic transitive invalidation across your entire caching layer.

Cachee vs Readyset — Cache Everything, Not Just SQL

Cachee vs Readyset:
Cache Everything, Not Just SQL

Readyset caches SQL query results for Postgres and MySQL. Cachee caches everything — API responses, session data, computed results, key-value pairs — at 1.5µs with AI-powered optimization.

Different tools, different scope: Readyset is clever for SQL-heavy workloads — it materializes query results and auto-invalidates on writes. But most modern applications cache more than SQL: API responses, session tokens, computed results, rate limits, feature flags. Cachee handles all of it at 1.5µs with AI-powered optimization.

Using Both — or Just Cachee

Flexible architecture: Use both where it makes sense: Readyset for automatic SQL query caching with write-through invalidation. Cachee for everything else — session state, API responses, computed results, rate limiting, feature flags. Or use Cachee alone with your application's caching logic for a simpler, faster, universal solution.
