Ably and Kafka are complementary solutions Both Ably and Kafka are event-driven solutions, sharing similar guarantees, messaging semantics, and characteristics. With Ably as a broker in the middle, you can seamlessly and scalably distribute Kafka data to web, mobile, and IoT clients at the edge.

Make an internet connected t-shirt with LEDs that respond to realtime data In summary: We will make a wearable, flexible LED array which will change colour in realtime as users draw on an app. It uses the Ably MQTT broker and the Ably Javascript SDK along with addressible RGB LEDs and an Adafruit wifi enabled microprocessor. We change the colour of individual LEDs sewn on the t-shirt, by sending realtime updates data with Ably's messaging platform to an Arduino via MQTT.

The Ably Flutter plugin brings awesome realtime magic to the much loved Flutter ecosystem. This is a demo of a Flutter chat app using the Ably Flutter plugin for realtime.

It makes it easy to deploy, manage, and distribute data streams to third party developers as realtime APIs - so they can consume and integrate those data streams into their own apps. As realtime API adoption increases so does complexity, cost, and friction of integration for developers wanting to consume realtime data. But with API Streamer, out-of-the-box realtime API management tools and a proven cloud distribution network mean creating self-service realtime API programs has fixed initial (near-zero) and ongoing engineering cost.

Flappy bird multiplayer gameplay

Hi there! In this video Ably's Dev Advocate, Srushtika Neelakantam, shows you how to build a multiplayer game of Flappy bird that you can play online with anyone. Along the way, you'll learn about the various networking strategies and realtime messaging concepts to build scalable multiplayer games over WebSockets using Ably.

In this masterclass, Ably’s Developer Advocate, Srushtika Neelakantam, will walk you through the basics of IoT and the realtime communication protocol these devices like to use i.e. MQTT.

In this masterclass, Ably’s Developer Advocate, Srushtika Neelakantam, will talk about realtime protocols and the various cool things you can do with them. She’ll then build a voting app from scratch that is production-ready and fully scalable. The app will show a dynamically changing graph reflecting the choices made by users on the voting questions, in realtime. Just some basic JavaScript knowledge is required to follow along.

In this masterclass, Ably’s Developer Advocate, Srushtika Neelakantam, will walk you through the basics of IoT and the realtime communication protocol these devices like to use i.e. MQTT. She’ll then show you how to build a realtime attendance logger from scratch.

In this video, Ably's Dev Advocate, Srushtika Neelakantam talks about Server-Sent Events (SSE) data transmission protocol, how it's different from other real-time protocols such as WebSockets and MQTT and how you can use SSE with Ably. The video ends with a quick tutorial followed by a short demo.
