Reviewer scorecard
“Essential infrastructure for any app that needs caching or pub/sub. Upstash makes it serverless and affordable.”
“Built-in vectorizer modules mean less glue code. GraphQL API is intuitive. Self-hosting option is a huge plus.”
“The license change burned some goodwill but Redis is still the best at what it does. Valkey is the hedge.”
“Open source and self-hostable gives you an exit strategy. The module system is genuinely innovative.”
“Redis modules (search, graph, time series) make it more than a cache. The platform expansion is working.”
“Multi-modal vectors and generative search point to where databases are heading. Weaviate is building for that future.”
