Ably

Ably is an enterprise-grade pub/sub messaging platform. We make it easy to efficiently design, quickly ship, and seamlessly scale critical realtime functionality delivered directly to end-users. Everyday we deliver billions of realtime messages to millions of users for thousands of companies.

We power the apps people, organizations, and enterprises depend on everyday like Lightspeed System’s realtime device management platform for over seven million school-owned devices, Vitac’s live captioning for 100s of millions of multilingual viewers for events like the Olympic Games, and Split’s realtime feature flagging for one trillion feature flags per month.

We’re the only pub/sub platform with a suite of baked-in services to build complete realtime functionality such as showing a driver’s live GPS location on a home-delivery app, instantly loading the most recent score when opening a sports app, and automatically handling reconnection when swapping networks.

Our platform is mathematically modelled around Four Pillars of Dependability so we’re able to ensure messages don’t get lost while still being delivered at low latency over a secure, reliable, and highly available global edge network.

Developers from startups to industrial giants choose to build on Ably because they simplify engineering, minimize DevOps overhead, and increase development velocity.
