What is CometChat?

CometChat is a versatile in-app Chat SDK & API that enables you to build real-time messaging, voice, and video calling features without the hassle of reinventing the wheel. With its modular SDKs and UI Kits, you can integrate basic voice calling in minutes or customize every detail for a fully branded experience. The platform handles millions of users, offers built-in AI moderation, and supports cross-platform notifications.

CometChat Overview

Founded with the mission to simplify real-time communication, CometChat has grown into a one-stop platform for chat, voice, and video. The team launched its first SDK in 2016, aiming to empower developers with plug-and-play components that scale seamlessly. Over the years, CometChat added powerful AI moderation, a Visual Builder for rapid prototyping, and advanced analytics to help businesses optimize engagement.

Today, CometChat supports industries from healthcare to gaming, serving startups and Fortune 500 companies alike. The platform’s flexibility—from lightweight JavaScript embeds to native iOS and Android SDKs—means you can start small and expand features as your user base grows.

Pros and Cons

Rich feature set out of the box: Instant messaging, 1:1 & group voice calls, file sharing, polls, and more are all included, reducing development overhead.

Visual Builder for rapid UI customization: Design chat and call screens visually, export React code, then fine-tune in your app.

AI-powered moderation: Dual-engine system catches harmful content in real time, keeping communities safe.

Scalable infrastructure: Global edge network ensures ultra-low latency calls even at high concurrency.

Comprehensive analytics: Track message and call metrics, user patterns, and engagement trends to inform product decisions.

Flexible pricing: Free tier for small projects, pay-as-you-go for voice/video minutes, and enterprise plans for large scale needs.

Cons:

Some advanced features like HIPAA compliance and custom white-label domain require enterprise plans, which may be cost-prohibitive for small teams.

Customization beyond UI Kits demands familiarity with the SDK architecture and may involve a steeper learning curve for junior developers.
