In their own words
SuperMassive
SuperMassive is a self-hosted, open-source key-value database built for in-memory work, durability, and low latency. It spreads data across shards, and additional nodes can expand capacity horizontally. Writes rotate among primary nodes in sequence; reads run in parallel across primaries and, when needed, replicas. The project describes automatic failover and recovery when a node fails. Timestamp-based versioning settles conflicts in favor of the latest value. Commands include PUT, GET, DEL, INCR, DECR, REGX, STAT, RCNF, and PING. Nodes journal operations, while replicas copy any missing journal entries from their primary. Client connections use username-and-password authentication; nodes can use shared keys, and TLS is optional. Linux, macOS, and Windows builds are available as binaries or source, under the BSD-3-Clause license. The README identifies two limits: no transactions and only one user. GitHub marks the repository archived and read-only as of May 6, 2026.
Upstash Redis
Upstash Redis is a fully managed, serverless Redis database in the cloud, with durable storage and pay-per-request pricing. It accepts connections over HTTP REST and the standard Redis TCP protocol. Databases can be replicated across regions for low-latency reads near users; the product describes multi-zone replication, automatic failover and persistence through restarts and failures. Listed use cases include caching, rate limiting, queues and streams, session storage, search and AI agent memory. It supports the Redis client protocol through version 8.4 and adds Search and Vector command families. Any Redis client can connect, including clients for TypeScript, Python, Go and Java. A Vercel integration can create or connect databases and expose environment variables to Vercel projects. TLS is enabled by default and cannot be turned off. The Free plan provides 256 MB of data, 10 GB of monthly bandwidth and 500K monthly commands. Pay as You Go is billed at $0.20 per 100K commands; storage and bandwidth charges may also apply. Its headquarters are in California.
