Ably (also known as Ably Realtime) is a British company based in London, United Kingdom.[1] The company is the developer of a global realtime messaging platform and provides APIs and SDKs for software developers.[2]
History
Ably was co-founded in 2013 by Matthew O'Riordan and Paddy Byers.[3] O'Riordan, who previously co-founded Econsultancy, is the CEO. Byers, who holds a PhD in Theoretical Computer Science from the University of Cambridge, serves as CTO.[3]
The founders spent three years in research and development before officially launching the platform in 2016.[4] The company has been supported by firms such as MMC Ventures, Insight Partners, and Dawn Capital.[5][6]
Technology
Ably's flagship product is Ably Pub/Sub, a WebSocket-based publish-subscribe platform built on a globally distributed edge network.[7][8] The platform has expanded with products that have SDKs and APIs available in multiple languages.[9] These enable developers to build realtime applications at scale with features such as live collaboration, live chat, data synchronisation, and notifications.[9]
In February 2023, Ably announced its integration with the Netlify Integrations Hub.[10] The company also launched a Next.js starter kit on the Vercel Templates Marketplace.[11]
Ably launched Spaces in October 2023, with an SDK for building collaborative application features such as avatar stacks, live cursors, and component locking.[12] The SDK allows developers to build collaborative environments similar to those found in applications like Figma and Google Docs.[13]
Ably launched Ably Chat in 2024.[14] Features include typing indicators, presence detection, message reactions, and support for various chat configurations from one-to-one to many-to-many rooms.[14]
In late 2025, the company announced Ably AI Transport, a drop-in infrastructure layer designed for AI agent applications, addressing the limitations of HTTP streaming for long-running, stateful AI interactions.[15]
Ably is also available through AWS Marketplace.[16]
