Transform static digital experiences with live updates
In today's fast paced world, users expect live updates, results and metrics to keep them informed. From live travel updates and the latest sports results to propagating feature flag changes in an application, timing is everything. Any delay to receiving this information would ultimately cause the user experience to fail.
Why Ably for live updates, results and metrics?
Focus on core product innovation. Ably is a Serverless WebSocket platform which removes traditional engineering complexities associated with data delivery at scale, such as deploying and scaling servers
Provide instant updates. Deliver updates to devices anywhere in the world with our global edge network, which ensures low latency last mile data distribution
Cater for all users. No one is left out with Ably's client library SDKs, which provides cross-platform support for all devices and browsers
Deliver information reliably. Depend on Ably to deliver mission-critical updates, with 5x9s uptime made possible by our fault tolerant infrastructure
We spoke to engineers at companies like LinkedIn, Slack, and Box who’d already built this type of infrastructure themselves. Everyone told us it would take a significant amount of upfront engineering coupled with non-trivial operating costs.
Build and deliver timely updates
