Reviewer scorecard
“Essential infrastructure for any app that needs caching or pub/sub. Upstash makes it serverless and affordable.”
“Write analytics once, send to every tool. The destination catalog and identity resolution are genuinely valuable.”
“The license change burned some goodwill but Redis is still the best at what it does. Valkey is the hedge.”
“Absurdly expensive at scale. RudderStack is the open-source alternative that does the same job.”
“Redis modules (search, graph, time series) make it more than a cache. The platform expansion is working.”
“Customer data infrastructure is essential but commoditizing. Segment's Twilio integration creates a unique data + communication platform.”
