# Redis

> Redis is the company behind the world's most popular in-memory data store, the open-source database that began as a side project by Salvatore Sanfilippo in 2009 and now sits in the stack of most of the internet's largest applications. It sells managed and self-hosted enterprise versions - Redis Cloud and Redis Software - layered on the open-source core, and has pushed hard into real-time AI use cases like vector search and LLM memory. After a turbulent 2024 licensing fight that spawned the AWS-backed Valkey fork, Redis returned to an open-source license (AGPLv3) with Redis 8 in 2025.
