Momento

Momento is a serverless data platform that provides low-latency, pay-as-you-go infrastructure without servers to provision, tune, or scale. Its core services are Momento Cache (an ephemeral serverless cache and drop-in Redis replacement), Momento Topics (a serverless publish/subscribe event bus), and Momento Leaderboards (massive, durable sorted sets). The platform is accessed over gRPC and a region-scoped HTTP API, with official SDKs for 15+ languages spanning browsers, mobile (iOS/Android/Flutter/Unity/Unreal), and 10+ server-side runtimes, plus a CLI and a Terraform provider. Authentication uses Momento API keys and short-lived disposable tokens with fine-grained permissions. Momento is backed by Bain Capital Ventures.

Momento publishes 1 API on the APIs.io network. Tagged areas include Company, Ai Infrastructure, Caching, Serverless, and Cache.

The Momento catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Momento’s developer surface includes documentation, API reference, getting-started guide, CLI, authentication, engineering blog, pricing, and 20 more developer resources.
