Reviewer scorecard
“Self-hostable, open source, and genuinely all-in-one. Replaces Amplitude + LaunchDarkly + Hotjar at a fraction of the cost.”
“Essential infrastructure for any app that needs caching or pub/sub. Upstash makes it serverless and affordable.”
“The free tier is absurdly generous. Open source means you can audit exactly what data goes where.”
“The license change burned some goodwill but Redis is still the best at what it does. Valkey is the hedge.”
“PostHog is the open-source Amplitude. The all-in-one approach reduces tool sprawl and keeps data unified.”
“Redis modules (search, graph, time series) make it more than a cache. The platform expansion is working.”
