About Momento

Momento provides caching and messaging infrastructure built around Valkey, the open-source fork of Redis. It started as a serverless cache and pub/sub service, and the current product line adds a fully managed Valkey cache in the cloud alongside components for teams that prefer to run Valkey themselves.

On the cloud side, Momento Cache is described as a fully managed, dedicated Valkey service. For self-hosting, the vendor ships a Valkey Router that works as a gateway, a Kubernetes-based Valkey Operator to control deployments, and a hardened Valkey container image. A Valkey Platform Toolkit targets platform engineering teams, and support plans cover each service.

Momento is a commercial product, so it is billed rather than free, and the vendor publishes a pricing page along with a contact-sales route for larger deployments. Typical users are application teams in areas such as media and game development who need low-latency caching at scale.
