Ably vs Continue: 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.

Continue is an open-source AI code assistant for VS Code and JetBrains that brings customizable, model-flexible AI help right into the editors developers already use. Rather than locking you into one closed platform, Continue lets you configure exactly which models you want to use — including your own keys and even local models — giving you control, flexibility and freedom from vendor lock-in while you get AI completion, chat and assistance inside your normal workflow.

Its strengths are openness and configurability. As an open-source project, it is transparent, community-driven and free, and its flexibility around models means you can tune it to your preferences, budget and privacy needs. It works across popular IDEs, so teams using different editors can share a consistent AI-assisted experience. For developers who want modern AI coding help without committing to a single proprietary editor or model provider, Continue offers a powerful, adaptable middle ground that respects how they already work.

Continue is ideal for developers and teams who value open source, want to choose and control their AI models, and prefer adding AI to their existing VS Code or JetBrains setup rather than switching editors. It sits alongside tools like Cline and Aider in the open-source AI-coding ecosystem, and is a flexible alternative to closed AI editors like Cursor. If you want customizable, open, model-agnostic AI assistance integrated into the IDE you already love, Continue is a standout choice that keeps you in control of both your workflow and your AI.
