This guide compares both platforms on chat features, UI customization, pricing, and integration effort, so you can find the right fit for your use case. [Start building for free](/dashboard/signup/premium/) [Migration support](/contact/) In brief TalkJS and Stream are both chat API platforms for adding real-time messaging to web and mobile apps. TalkJS ships a complete, drop-in chat UI that lives in your own codebase, charges per MAU only, and gives you direct engineer support on every plan. Stream provides individual UI components you assemble into a full chat product, backed by a global edge network and stronger compliance certifications for healthcare and US enterprise. For most teams that primarily need in-app chat and want to ship fast without billing surprises, TalkJS typically offers faster time-to-market, more UI ownership, and more predictable pricing at scale. Stream is worth evaluating if you need HIPAA compliance, SOC 2 certification, a dedicated moderation dashboard, or a global edge network for latency-sensitive workloads. **Disclosure:** This comparison was written by TalkJS. We've aimed to be accurate and fair, but we encourage you to evaluate both platforms for your specific needs. Pricing and features are current as of June 2026. 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 ships a fully rendered, production-ready chat UI as a single component that drops into your existing codebase, customizable with your own HTML, CSS, and JavaScript, version-controlled like any other frontend code. With MAU-based pricing, built-in notification delivery across push, email, and SMS, and direct engineer support on every plan, TalkJS is designed for product teams who want to ship chat fast and scale it predictably. When to choose TalkJS - You need in-app chat live fast. Many teams ship in 2–5 days. - You want a complete, drop-in chat UI you can fully customize, or go fully headless via the Data API - You want your chat UI to live in your own codebase with full version control - You need rich notifications out of the box: push, email, SMS, and reply-via-email - You want predictable, MAU-only pricing that doesn't spike with message volume, channel count, or API usage - You need ISO 27001 compliance with European data residency - You want direct support from engineers on every plan, not just enterprise What is Stream? Stream is a chat API and SDK platform built around a global edge network, offering a broad set of UI components. It is designed for teams that need to assemble a fully custom chat experience from individual components (such as message list, channel list) and who need enterprise-grade compliance certifications or dedicated moderation tooling. Stream's pricing model meters usage across multiple dimensions including message storage, channels, API calls, and bandwidth alongside MAU, giving flexibility for varied workloads at the cost of billing predictability. When to choose Stream - You require HIPAA compliance or SOC 2 certification for US enterprise procurement - Your product needs a dedicated moderation dashboard and built-in AI moderation tooling - You need a global edge network for latency-sensitive applications with a geographically distributed user base - Your team has the engineering capacity to assemble and maintain a full chat UI from individual SDK components - You need thread replies as a core native feature - You require a 99.999% uptime SLA - Your pricing model benefits from usage-based billing rather than a flat MAU rate ## Compare TalkJS and Stream TalkJS leads on pricing predictability, UI customization, notification delivery, and support access on every plan. Stream leads on moderation tooling, compliance certifications for healthcare and US enterprise, and global infrastructure. For teams building a chat-first product who want to ship fast and scale without billing surprises, TalkJS is the stronger choice. | | TalkJS | Stream | #### Why it matters | | | | | --- | --- | --- |

Ben Klenk Co-founder & CEO, Hotplate > TalkJS allowed our team to focus entirely on core marketplace features instead of maintaining chat infrastructure. Youssef CTO, GameBoost ## TalkJS pricing vs Stream TalkJS pricing is based on Monthly Active Users (MAU) only, with unlimited messages, channels, and API calls included on all plans. Stream's pricing includes MAU plus separate metered limits on message storage, channels, API calls, and bandwidth, each billed at overage rates when exceeded. ### How many MAU? 5 K 10 K 25 K 50 K 100 K #### TalkJS Basic $239/month Growth $499/month Enterprise Custom #### Stream Start $399/month Elevate $599/month Enterprise Custom ## Migrate to Talkjs from Stream in less than 30 days Our migration team will help you handle the transition with zero downtime. - Step-by-step migration guide - Data import tools - Dedicated migration support by a TalkJS engineer Your name Email address Company name Optional Company website Optional How are you looking to use TalkJS?

For most chat use cases, TalkJS will be more predictable and often cheaper at scale. TalkJS charges per Monthly Active User (MAU) only, so your costs grow with your user base, not with how much your users chat. Stream charges per MAU but also meters message storage, channels, API calls, API bandwidth, and CDN usage separately, each with its own cap and overage rate. A product with high message volume, many channels, or heavy media sharing can generate significant Stream costs even with a modest user base. TalkJS's MAU-only model means none of those usage dimensions affect your bill. Which platform is faster to integrate? TalkJS. Many teams ship to production in 2–5 days, and a working proof of concept can be built in under an hour. TalkJS ships a fully rendered chat UI as a single React component or web component that drops into your existing codebase. Stream provides individual UI components (such as message list, channel list, message composer) that you assemble into a complete UI yourself, which requires significantly more frontend work before you have something shippable. Does Stream have a pre-built chat UI? Stream provides individual UI components for React, iOS, Android, Flutter, and Angular, but not a complete ready-to-use chat UI. You assemble those components into a working product yourself. TalkJS ships a fully rendered inbox, chatbox, conversation list, and popup out of the box, each fully customizable with HTML, CSS, and JavaScript. If your team wants to minimize frontend build time, TalkJS gets you to a working chat significantly faster. How does UI customization differ between TalkJS and Stream? Both platforms support deep UI customization, but the model is fundamentally different. With TalkJS, your chat UI code lives in your own codebase as a React or web component. You style it with your own CSS, version-control it like any other frontend code, and it behaves like any other part of your application. With Stream, customization works by overriding components within their SDK framework, bound by their component architecture and upgrade cycle. TalkJS's approach gives you more ownership; Stream's approach gives you a prebuilt structure to work within. Does TalkJS support email and SMS notifications? Yes. TalkJS includes email notifications, SMS notifications, and push notifications on all plans. It also includes a reply-via-email feature where users can reply to a notification email and have their response sync back into the chat. On Growth plans and higher, you can customize notification emails with full HTML and CSS and send them from your own domain. Stream supports push notifications but email and SMS notification capabilities are not confirmed in their public documentation. Which platform has better moderation tools? Stream has the stronger built-in moderation tooling. It includes a dedicated moderation dashboard, moderator user roles, message flagging, pre-send message hooks, and AI moderation as an Enterprise add-on. TalkJS includes a profanity filter with regex-based keyword blocklists and mute, ban, and block controls, but doesn't have a dedicated moderation dashboard. TalkJS does support integration with third-party moderation vendors if you need more advanced capabilities. If moderation is a core requirement of your product, Stream's tooling is more complete out of the box. Which platform is better for compliance-heavy industries? It depends on your requirements. Both are ISO 27001 certified and GDPR compliant. Stream additionally holds SOC 2 and offers HIPAA compliance on Elevate plans and higher, making it the stronger choice for US-based healthcare applications or enterprise procurement processes that require SOC 2. TalkJS offers EU data residency and on-premise/private cloud options as Enterprise add-ons. If HIPAA or SOC 2 are hard requirements, Stream is the right choice. If ISO 27001 and GDPR cover your needs, TalkJS is the stronger option for chat. Does Stream support unlimited message history? Not on standard plans. Stream caps message storage at 5 million messages on the Start plan and 10 million on Elevate, with overages charged at $6 per million messages. TalkJS includes unlimited message retention on all plans with no overage fees. Can I migrate to TalkJS from Stream? Yes. TalkJS supports full data migration including message history and conversation state. Our migration team provides dedicated support throughout the process to minimize disruption to your users. Does TalkJS support threads? Not as a built-in feature, but TalkJS provides a tutorial for adding threaded replies yourself. Stream includes threads natively. If threads are a core requirement for your product, this is worth factoring into your evaluation. **Disclaimer:** This comparison is current as of June 2026 and based on publicly available information from TalkJS and Stream.
