Sendbird

Sendbird is the Korean-founded customer-communications platform whose chat, messaging and AI agent APIs power in-app conversations for thousands of apps worldwide.

Overview

Sendbird began as an in-app chat API and grew into a full engagement platform covering chat, calls, SMS and, more recently, AI agents that resolve customer issues inside products. Its AI agent is grounded in the business’s own knowledge sources and hands off to human agents inside the same conversation thread when needed. The platform is known for reliability at scale, with SDKs for every major mobile and web framework, and it is widely used by marketplaces, fintechs and healthcare apps.

Key Features

• In-app chat, messaging and calls APIs with mobile SDKs
• Sendbird AI agent grounded in business knowledge for automated resolution
• Seamless human handoff with full conversation context
• Omnichannel delivery: in-app, SMS and notifications
• Moderation, translation and analytics tooling included
• Enterprise-grade reliability and compliance certifications

Pricing

Sendbird offers a free trial, then usage-based plans that scale with monthly active users and message volume; enterprise tiers add security, support and AI agent pricing.

Who Is It For

Product and support teams at marketplaces, fintech, healthcare and on-demand apps that want branded conversations and AI resolution without building chat infrastructure.

Use Cases

Sendbird is the messaging backbone for apps where conversation is part of the product — marketplaces, telehealth, fintech and on-demand services.

• In-app chat between buyers, sellers and support teams
• AI agents that resolve routine service requests
• Omnichannel messaging across app, SMS and notifications

Getting Started

Developers add the SDK, configure channels and ship; the free trial and generous docs make a working chat prototype fast. AI agent setup starts from your existing knowledge base.

Results to Expect

Teams launch production-grade messaging in weeks rather than quarters, and AI resolution deflects routine tickets while humans keep the complex, high-value conversations.

Implementation and Support

Developers integrate SDKs with excellent documentation and can be live quickly; AI agents are configured from existing knowledge sources with Sendbird’s support.

Limitations to Keep in Mind

Costs scale with monthly active users and message volume, so high-traffic apps should model pricing early.

What Users Say

Teams praise reliability at scale and the speed of shipping in-app chat versus building it themselves.
