In brief

TalkJS and Ably are both real-time messaging platforms, but they’re built for different problems. Ably is a real-time infrastructure company whose product suite spans pub/sub messaging, data synchronization, AI transport, chat, and more. TalkJS is purpose-built for in-app chat: it ships a fully managed, white-label messaging experience with a pre-built UI, rich notifications, and moderation tools out of the box. If you primarily need to add chat to a web or mobile product, TalkJS typically offers faster time-to-market, more out-of-the-box functionality, and more predictable pricing. Ably also covers real-time use cases beyond chat and offers a HIPAA BAA on its Enterprise plan. TalkJS is ISO 27001 certified and hosts your data in the EU by default.

What is TalkJS?

TalkJS is a chat API and SDK platform that lets teams add white-label in-app messaging to web or mobile applications. It combines a fully customizable pre-built UI with a reliable backend, rich notification delivery, and built-in moderation, so product teams can ship production-ready chat without building it from scratch. Designed for teams that want control over the look, feel, and behavior of their chat, without the engineering overhead of maintaining real-time infrastructure.

You need in-app chat live fast. Many teams ship in 2–5 days.
You want a pre-built UI you can fully customize to match your brand, or go headless
Your use case is primarily chat (not data sync)
You need rich notifications out of the box: push, email, SMS, and reply-via-email
You want predictable, MAU-based pricing that doesn’t spike with message volume
You need ISO 27001 compliance with European data residency
You want direct support from engineers on every plan, not just enterprise
You’re migrating from another chat provider and need a smooth transition

What is Ably?

Ably is a real-time platform that provides infrastructure for building live, collaborative, and event-driven applications. Its product suite includes Pub/Sub messaging, Chat, Spaces (collaborative environments), LiveSync (database synchronization), and AI Transport. Ably’s infrastructure is globally distributed and designed for high-throughput, latency-sensitive workloads at any scale. Ably Chat provides the core primitives for building messaging features but doesn’t include a pre-built UI, email or SMS notifications, or moderation tools out of the box. It’s for teams with the engineering capacity to assemble the lower-level building blocks themselves.

Ably Chat gives you building blocks and a React UI Kit, but no email or SMS notifications. TalkJS ships a pre-built UI and push, email, and SMS notifications.
Ably holds SOC 2 Type 2 and offers a HIPAA BAA on its Enterprise plan. TalkJS is ISO 27001 certified and hosts your data in the EU by default.
Ably can charge per message, connection minute, and channel minute. TalkJS charges per MAU, so busy chats don’t cost you more.

FAQs

It depends on your usage pattern, but for most chat use cases TalkJS will be more predictable and often cheaper at scale. TalkJS charges per Monthly Active User (MAU), so your costs grow with your user base, not with how much your users chat. Ably charges either per MAU or per message, connection minute, and channel minute, which can add up quickly in high-frequency chat scenarios. A busy group chat where users send many messages per session can generate significant Ably usage costs even with a modest user base. TalkJS’s MAU model means talkative users don’t cost you more.

Ably Chat provides a UI Kit for React, but doesn’t ship a ready-to-use chat UI the way TalkJS does. With TalkJS you get a fully rendered inbox, chatbox, conversation list, and popup out of the box. Each of these is fully customizable with HTML, CSS, and JavaScript. With Ably Chat, you build and maintain the UI yourself using their lower-level primitives.

TalkJS. Many teams ship to production in 2–5 days, and a working proof of concept can be built in under an hour. Ably Chat provides the building blocks for chat, but assembling a full product including UI, notifications, moderation, and email delivery would require significantly more engineering work.

Yes. TalkJS includes email notifications, SMS notifications, push notifications. It also offers a reply-via-email feature where users can reply to a notification email and have their response sync back into the chat. Ably Chat doesn’t include email or SMS notification delivery out of the box.

TalkJS includes a profanity filter with regex-based keyword blocklists, message removal, user role controls, and the ability to suppress contact information sharing, which are available on all plans.

Ably does offer integration with third-party moderation vendors if you need automated content moderation at scale.

No, currently not. Read receipts are listed as coming soon on Ably’s pricing page as of June 2026. TalkJS has supported read receipts since launch.

TalkJS is ISO 27001 certified and GDPR compliant. We host your data in the EU by default and act as a GDPR data processor, with data processing terms in our Terms of Service. Ably holds SOC 2 Type 2 and offers a HIPAA BAA on its Enterprise plan. If you need full control over where your chat data is stored, TalkJS Enterprise offers on-premise and private cloud installs as an add-on.

No. Ably is a broader real-time platform that includes pub/sub messaging, collaborative environments (Ably Spaces), database synchronization (LiveSync), and AI transport, in addition to Chat. If in-app chat is what you need, TalkJS gives you the chat UI, notifications, and moderation ready-made, so there’s less for you to build.
