GetStream vs Sendbird vs CometChat: Chat API 2026
GetStream vs Sendbird vs CometChat: Chat API Comparison 2026
TL;DR
GetStream (now Stream) leads on developer experience and React component quality — the fastest path from zero to a production-grade chat UI. Sendbird is the enterprise incumbent with the broadest feature set, advanced moderation, and strong compliance tooling, but at higher cost. CometChat sits in the middle: reasonable feature depth, competitive pricing, and a good fit for teams building social or community features without enterprise procurement budgets. For most SaaS startups, Stream wins on DX and pricing. For regulated industries or large user bases requiring deep moderation, Sendbird is worth the premium.
Key Takeaways
- Stream: 5B+ messages/day delivered; React, React Native, Flutter, SwiftUI, Jetpack Compose SDKs; free tier up to 25 MAU
- Sendbird: 300M+ end users on the platform; 95% of Fortune 100 companies use it; strongest enterprise moderation and compliance tooling
- CometChat: Fastest integration path for voice/video/chat combo; free tier for up to 25 users; white-label UI kits available
- AI features: All three launched AI chat moderation and message summarization features in 2025–2026
- Pricing model: All are MAU-based (monthly active users), making costs predictable but potentially expensive at social-app scale

Stream (GetStream): Best Developer Experience
Stream rebranded from "GetStream" in 2024 to reflect its expansion beyond chat into video and activity feeds. It remains the first choice for teams prioritizing React component quality and time-to-ship.
SDK quality
Stream's React component library is the most polished in the market. You get:
import { Chat, Channel, ChannelList, MessageList, MessageInput } from 'stream-chat-react';
function App() {
const client = StreamChat.getInstance(API_KEY);
await client.connectUser({ id: userId, name: userName }, userToken);
return (
<Chat client={client}>
<ChannelList />
<Channel>
<MessageList />
<MessageInput />
</Channel>
</Chat>
);
}
The components handle virtual scrolling for large message histories, optimistic updates, file uploads, reactions, threads, mentions, and read receipts out of the box.
Stream AI Assistants
Launched in 2025, Stream AI lets you embed an AI assistant as a chat participant that responds to user messages via OpenAI, Anthropic, or a custom LLM endpoint. It handles streaming responses token-by-token and shows typing indicators while the model generates.
Stream Pricing (2026)
| Plan | MAU | Price/month |
|---|---|---|
| Free | 25 | $0 |
| Starter | 250 | ~$99 |
| Pro | 5,000 | ~$299 |
| Business | 10,000+ | ~$499+ |
Messages are unlimited on paid plans. MAU overage rates apply beyond plan limits.
Stream Limits
- Moderation tooling is good but not as deep as Sendbird's (no native SafeGuard AI equivalent)
- Video/voice is a separate product (Stream Video) billed independently
- No self-hosted option
Sendbird: Enterprise-Grade Chat Platform
Sendbird has been in market since 2015 and has the deepest feature set of the three. If you're building for healthcare, finance, or marketplace platforms with complex moderation requirements, Sendbird's tooling is hard to match.
Sendbird's differentiators
SmartAssistant (AI chatbot): Sendbird's AI product is more mature than Stream's. You can deploy a SmartAssistant trained on your product documentation or knowledge base to handle first-touch support before handing off to human agents. It integrates with Zendesk, Salesforce, and Freshdesk.
Moderation ecosystem: Sendbird offers:
- Image and text content moderation (via internal ML + third-party integrations)
- User reputation scoring
- Shadowban, soft-delete, freeze channel controls
- Audit logs for compliance teams
Desk (Customer Service): Sendbird's CX product layer adds agent routing, SLA management, CSAT scoring, and Salesforce integration — turning a chat SDK into a full customer service platform.
Sendbird Pricing (2026)
Sendbird prices on DAU (daily active users), not MAU — an important distinction that makes their free tier seem larger than it is (30 DAU ≠ 30 MAU at typical engagement rates).
| Plan | DAU | Price/month |
|---|---|---|
| Free | 30 | $0 |
| Starter | 500 | ~$399 |
| Pro | Custom | Custom |
| Enterprise | Custom | Custom |
Sendbird is meaningfully more expensive than Stream at equivalent scale. For a consumer app with 5,000 MAU and average 20% daily engagement (~1,000 DAU), expect Starter pricing in the $399–$600/month range.
Sendbird Limits
- Most expensive of the three at comparable MAU
- DAU-based pricing is harder to predict than MAU-based
- SDK API has more surface area (more powerful, but steeper learning curve)
CometChat: Competitive Middle Ground
CometChat targets the team that wants voice + video + chat in one package without Sendbird pricing. Its UI kits cover React, React Native, iOS, and Android with a consistent design system.
CometChat's strengths
Voice and video native: Unlike Stream (where video is a separate product), CometChat includes voice calls, video calls, and group calling as first-class features in the base SDK. This matters for social apps, telehealth, and marketplace platforms where switching between chat and video is core UX.
White-label UI Kits: CometChat's customization model is based on component-level theming, letting you match your brand without rebuilding UI components from scratch.
Mentions, reactions, typing indicators, read receipts, push notifications — all included at all paid tiers.
CometChat Pricing (2026)
| Plan | Users | Price/month |
|---|---|---|
| Free | 25 | $0 |
| Startup | 500 | ~$149 |
| Growth | 10,000 | ~$399 |
| Enterprise | Custom | Custom |
CometChat's self-hosted enterprise tier is unique — if you need on-premise deployment for compliance, it's the only one of the three with that option.
CometChat Limits
- React component library is less polished than Stream's
- Enterprise self-host has a significant setup cost
- Smaller ecosystem and fewer third-party integrations than Sendbird
Feature Deep Dive: Moderation
| Feature | Stream | Sendbird | CometChat |
|---|---|---|---|
| Text moderation | Via Moderation API | Built-in + AI | Via third-party |
| Image moderation | Yes | Yes (SafeGuard) | Yes |
| User muting/banning | Yes | Yes | Yes |
| Shadowban | No | Yes | Yes |
| Audit logs | Limited | Full | Limited |
| CSAM detection | No | Yes | No |
| Auto-moderation rules | Basic | Advanced | Basic |
Sendbird's SafeGuard AI moderation (launched 2024) is the most mature option — it combines content classification, user reputation, and rule-based triggers into a single moderation layer.

CometChat offers the most predictable cost at this scale. Sendbird is most expensive. Stream sits in the middle with the best component library.
Which Chat API Should You Use?
Choose Stream if you're building a SaaS product and your team works primarily in React. The SDK quality and documentation are the best in category, and the $99–$299 startup tier gives room to grow.
Choose Sendbird if you're in a regulated industry, need deep moderation with audit trails, or are building a customer support workflow on top of chat. The premium pricing reflects genuine depth in compliance, moderation, and CX integrations.
Choose CometChat if you need voice + video + chat in one package at a price below Sendbird, or if on-premise self-hosting is a hard requirement.
