Chat UI Implementation: A Complete Guide To Developers (2025)

Explore Chat UI Kit

Chat UI, or Chat User Interface, refers to the design and layout of a chat app. This is the point where your users can interact with your app. Your chat interface will include display screens, buttons, navigation elements, and themes. 

In simple words, a chat interface works based on the ‘if-then’ logic. Your app’s source code will have predefined answers set for each user input. When a user touches a button or selects an item in a menu, the source code fetches the related response from the backend and delivers it at the front end.

Chat UI Components You’ll Need For Your App

When you start building your chat app, one of the most important prerequisites is to prepare a checklist of the UI elements that your app will include. To reduce your burden of preparing one, we enlisted the key features that you’ll need to add to your app:

• Chat log: Users will need the history of previous conversations with each of their contacts logged in the chat window
• Chat Window: The main window where users converse with each other
• Emojis/ Stickers: Graphical icons that let users emote their feelings more comically
• Group chat: Lets multiple participants take part in the same conversation
• Input Pane: The field where users type their messages before sending them
• Media Sharing: The feature to share images, videos, gifs, and documents with other users
• Notifications: Alerts users on any incoming message
• Profile Picture: An image or icon that represents the identity of the user in the Chat UI
• Search: Lets users search and find specific user/ message
• Send Button: Once users complete typing the message on the input pane, they’ll need a send button to confirm the sending of their message
• Timestamps: The log of time when each message was sent/ received
• Participant list: List of users participating in the group conversation and their online presence status
• Settings: Gives users the right to customize their profile, privacy, notifications, and backups.
• Video/ Voice Call: In addition to instant messaging, users will also look to converse with others over a video or voice call.

Technical Requirements For Building An Engaging Chat UI 

To give you users a smooth messaging experience, you’ll need to fulfill the major and modern technical requirements of your chat app. This helps you establish efficient communication along with user satisfaction to drive more conversions.

So, here are the technical requirements you’ll need when building a chat UI:

Real-time Messaging:

The key reason why users choose to use a chat app instead of traditional messaging apps is the spontaneity of communication and real-time features. In this accord, you’ll need to ensure that your UI is built with technologies like WebSockets or Firebase to implement real-time chat.

Authentication:

Authentication: It is essential that your chat UI needs to allow only authorized users to access the chat conversation. For this, you may need to use technologies like OAuth or JWT to establish an authentication system.

Security:

 Your chat app may handle billions of users from different locations, devices and platforms. This demands a highly secure environment to ensure that no user data or conversation is accessed by unauthorized users. This is where security protocols like end-to-end encryption, HTTP, TLS/ SSL come for the save. It is wise to use APIs with built-in protocols, so you need not set up a full infrastructure and maintain it.

Chat Backup:

 You’ll need to set up chat logs or backup options for your users in order to help your users save their conversations and data for future purposes. This includes provision on storage, most importantly without accessing any information backed up by the user.

Well, now you know what you’ll need to build a  chat UI. Now, we’ll look into how to build the user interface for your chat apps. For this, we’ll first check the programming languages and frameworks upon which your chat UIs can be built. 

Tech Stacks Commonly Used For Building Chat UIs

Typically, the first step of building a chat UI is to choose the tech stack that is suitable for your web or mobile application. Here are the most popular choices of developers around the world when it comes to building user interfaces.

Javascript:

Javascript is a great option if you are looking to build for the front and backend of the UI in the same language. You can use React, Angular, and Vue.js frameworks to seamlessly build the app interface. Javascript developers can help you to build UI fully at a professional level.

WebSockets:

If you are building a real-time web app, you can go for the WebSocket protocol. This helps you to easily establish two-way communication between the web browser and the server. 

Node.js:

This Javascript runtime is a popular option for developers for building chat UIs for server-side apps.

WebRTC:

For chat apps that come with video and voice call functionality, WebRTC is a good option. This open-source protocol helps you to establish real-time communication between browsers and mobile apps.

React Native:

This framework uses the same codebase to build native apps for Android and iOS, using Javascript and React

Firebase:

This Backend-as-a-Service (BaaS) platform  gives you a rich source of tools to build real-time apps with real-time database, server hosting and user authentication

GraphQL:

This query language helps you build chat UIs by flexibly combining them with other technologies like React or Node.js.

These frameworks are commonly used for chat UI implementation. You might need to work on the basic requirements to choose which among the languages in the list will best fit your project.
