What to weigh when you compare chat APIs
Check these points against what your app needs. Each one says how TalkJS handles it, limits included.
TalkJS ships a pre-built chat UI as React and Web Components. Theme components let you replace parts of it with your own components, and the Data APIs for JavaScript, Kotlin, Swift, and Flutter let you build your own UI.
Email, SMS, and push notifications are built in on every TalkJS plan, with reply by email. They don't need your own SendGrid or Twilio account. SMS is charged separately.
TalkJS is chat-first and has no native voice or video calling. You can integrate a calling provider of your choice next to TalkJS chat. Sendbird, CometChat, and Stream have their own calling products.
TalkJS is ISO 27001 certified, GDPR compliant, and hosts data in Europe (see Security). It doesn't have SOC 2 and doesn't sign a HIPAA BAA, so if you need either, compare the vendors that do.
TalkJS bills per monthly active user (MAU), not per message or connection. Each plan includes a number of MAU, and you pay per user beyond that. See pricing.
Chat and email support from engineers on every TalkJS plan, priority support from the Growth plan, and a named Solutions Engineer on the Enterprise plan.
