After encountering significant problems in scaling some types of workloads using traditional database systems, Sanfilippo began to prototype a first proof of concept version of Redis in Tcl. The Redis project began when Salvatore Sanfilippo, nicknamed antirez, the original developer of Redis, was trying to improve the scalability of his Italian startup, developing a real-time web log analyzer. The name Redis means Remote Dictionary Server. In 2021, not long after the original author and main maintainer left, redisLabs dropped the Labs from its name and now redis, the open source DB as well as redisLabs, the commercial company, are referred to as "redis".

It is open-source software released under a BSD 3-clause license. Salvatore Sanfilippo left Redis as the maintainer in 2020. From 2015 until 2020, he led a project core team sponsored by Redis Labs. The project was developed and maintained by Salvatore Sanfilippo. Redis supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, HyperLogLogs, bitmaps, streams, and spatial indices. Redis ( / ˈ r ɛ d ɪ s/ Remote Dictionary Server) is an in-memory data structure store, used as a distributed, in-memory key–value database, cache and message broker, with optional durability.
