Ably vs Apify: Which Is Better in 2026?

Ably is a realtime experience and messaging infrastructure platform that provides the building blocks for adding live, scalable features — like chat, presence, live updates, notifications and data broadcasting — to applications. Building reliable realtime functionality is genuinely hard: it requires maintaining persistent connections, handling scale, guaranteeing message delivery and ordering, and managing the complexities of distributed systems. Ably abstracts all of this into dependable infrastructure delivered through simple APIs, so developers can ship realtime features without building and operating the hard underlying systems themselves.

The platform offers pub/sub messaging, presence (knowing who's online), message history, and guaranteed delivery and ordering, all built to scale to millions of connections with high reliability and low latency across a global network. Developers use Ably to power experiences like live chat, collaborative apps, live sports and finance updates, multiplayer features, IoT data streaming, and realtime notifications — anywhere data needs to move instantly and reliably between servers and many clients. With SDKs across platforms and a focus on dependability (including strong delivery guarantees and uptime), it provides the trustworthy realtime backbone that these features require.

Ably is used by companies and developers that need to add realtime functionality to their products and want robust, scalable infrastructure rather than building and maintaining it in-house. By handling the difficult engineering of realtime messaging at scale — connections, delivery, ordering, presence and global distribution — it lets teams focus on their application features and ship realtime experiences confidently. Its emphasis on reliability and scale makes it suitable for serious, production use where realtime data matters. As users increasingly expect live, collaborative and instantly-updating experiences, dependable realtime infrastructure is increasingly important. For developers and companies that want to build live, scalable realtime features without operating the underlying systems, Ably offers a powerful, reliable and well-regarded solution.

Apify is a comprehensive platform for web scraping, data extraction and browser automation, giving developers and businesses the tools to collect data from any website and automate web-based workflows at scale. It combines a marketplace of ready-made scrapers and automation tools ("Actors") with the infrastructure to build, run and scale your own — covering the full spectrum from non-technical users who just need data from a specific site to developers building sophisticated, custom scraping and automation solutions.

At the heart of Apify is its store of pre-built Actors that scrape popular websites and perform common automation tasks, so you can often get the data you need without writing any code — just configure an existing scraper for sites like search engines, social platforms, marketplaces and more, and run it. For custom needs, Apify provides a powerful platform and open-source libraries to build your own scrapers and automations, with managed cloud infrastructure that handles running them reliably at scale, dealing with the hard parts like proxies, browser automation, scheduling, storage and avoiding blocks.

This dual approach — ready-made tools plus a robust build-your-own platform — makes Apify versatile and widely used for market research, lead generation, price monitoring, content aggregation, SEO, training data collection for AI, and countless other use cases that depend on web data. It integrates with other tools and offers APIs so extracted data flows into your systems. As demand for web data continues to surge — driven heavily by AI's appetite for training and real-time information — capable, scalable scraping and automation infrastructure has become increasingly important. Apify is one of the most established and full-featured platforms in this space. For developers and businesses that need to extract data from the web or automate web tasks — whether through ready-made scrapers or custom-built solutions, at any scale — Apify offers a powerful, flexible and proven platform.
