JuggleIM is a high-performance, scalable instant messaging platform with an open-source Go server, multi-platform client SDKs, REST APIs, WebHooks, admin tooling and related developer components.
For developers who want to evaluate JuggleIM or build their own messaging product, we also provide an open-source JuggleChat Server and open-source UI demo/reference applications for Web, iOS, and Android.
These open-source projects are intended for evaluation, integration reference, learning, and custom development.
JuggleChat is a separate production-ready commercial messaging product built by the JuggleIM team. It provides complete application source code for teams that want to launch a full messaging product without building every product-level feature from scratch.
Important
The open-source JuggleChat Server and UI demos are developer reference projects. They are not the complete commercial JuggleChat product source code.
Choose a self-hosted private deployment for full control over data and infrastructure, or use the managed cloud to start quickly. The same platform supports everything from a two-person conversation to a 100,000-member group and large live chatrooms.

Use the JuggleIM SDK if you already have an application and only need messaging capabilities.
Use the open-source UI demos if you want to evaluate JuggleIM, understand integration patterns, learn from sample UI/business logic, or use them as a reference for your own development.
Use commercial JuggleChat if you need a complete, production-ready messaging product that can be deployed and customized directly.
Pick the shortest path for your goal:
- Host your own IM service — follow the one-click deployment guide or explore im-server.
- Add chat to an existing product — choose a client SDK and connect it through the documented server APIs.
- Ship a complete messenger — use JuggleChat as a full-stack starting point and customize the clients for your product.
Explore the product overview, SDK documentation, and server API reference for integration details.
- Social & communities: direct messages, friend relationships, large groups, mentions, reactions, and read receipts.
- Marketplaces & support: buyer–seller conversations, service notifications, message history, and moderation hooks.
- Live experiences: high-concurrency chatrooms for comments, likes, gifts, room state, and interactive events.
- AI & automation: bot SDKs and connectors for assistants, workflows, and LLM-powered conversations.
