The good news is that creating a 1v1 chatting app doesn’t have to be a time-consuming or complex task. With the right tools, like ZEGOCLOUD Chatkit, you can build a fully functional chat app in as little as 30 minutes.
Why Do People Use Messaging Apps?
People use messaging apps not only for their convenience and functionality but also due to their widespread adoption, as supported by data. For instance, according to Statista, as of 2024, over 3.5 billion people worldwide use messaging apps, with the most popular ones boasting more than 2 billion monthly active users. This highlights the growing reliance on instant communication for both personal and professional purposes.
Cost-effectiveness is another key factor driving their popularity. Messaging apps, which rely on internet connections, save users billions of dollars annually compared to traditional SMS. Additionally, features like group chats and video calls cater to diverse communication needs. During the pandemic, the usage of apps like WhatsApp surged by over 40%, demonstrating their crucial role in maintaining connections when in-person interactions were limited. These statistics underscore the transformation of messaging apps from simple chat tools to multifunctional platforms.

Build vs Buy chat app
When deciding whether to build or buy a chat app, it’s important to weigh the costs, customization needs, and long-term goals of your business.
| Factor | Build (Custom Chat App) | Buy (Pre-built Chat App / SDK/API) |
|---|---|---|
| Customization | High customization, can tailor features and design to specific needs. | Limited customization, restricted by the features and design provided by the third-party. |
| Development Cost | High development costs, requires significant resources (development, testing, maintenance). | Lower initial cost, typically a subscription or one-time licensing fee. |
| Time to Market | Long development and testing phase, slower to launch. | Quick implementation, faster time to market. |
| Scalability | Can be designed for scalability and grow with your business needs. | Scalability may be limited by the third-party service, may not adapt well to future needs. |
| Data Ownership | Full control over data, better for privacy and compliance with regulations. | Data may be stored on third-party servers, potential privacy and compliance risks. |
| Competitive Advantage | Custom solutions can differentiate from competitors and offer unique user experiences. | Standardized solutions might not provide a unique advantage, easily replicated by competitors. |
| Maintenance | Ongoing maintenance required for bug fixes, updates, and support. | Maintenance is handled by the service provider, reducing operational burden. |
| Reliability | Dependent on the development team’s technical capabilities, may face more bugs or performance issues initially. | Generally more reliable, tested and optimized by the provider. |
Time and Cost of Chat App Development
When considering the development of a chat app in-house, there are several factors that can significantly influence both the time required and the overall cost. Here’s a breakdown of the key aspects that affect these variables:
1. Basic Chat App
For an app that includes basic features like text messaging, user profiles, and group chats, you can expect development to take approximately 3 to 6 months. The cost for such an app generally ranges from $20,000 to $50,000, depending on the complexity of the backend and the design.
2. Medium Complexity Chat App
If you require more sophisticated features, such as voice/video calls, end-to-end encryption, push notifications, and media sharing, the development timeline could extend to 6 to 12 months, with an estimated cost between $50,000 to $100,000.
3. Advanced Chat App
For a high-end app featuring complex capabilities like real-time collaboration, social networking features, AI integrations, or gamification, development could take 12+ months and may cost anywhere from $100,000 to $250,000 or more, especially if you require highly customized solutions and advanced infrastructure.
What are the Technical Challenges When Building a Chat App?
When building a chat app, there are several technical challenges to address, but the four most important ones are:
1. Real-Time Messaging
The core of any chat app is real-time communication. Ensuring that messages are delivered instantly and reliably is crucial. This involves handling low latency, maintaining message order, and ensuring scalability as the number of users grows.
2. Security and Privacy
User data privacy is a top priority. Implementing end-to-end encryption (E2EE) ensures that only the sender and recipient can read the messages. Additionally, secure authentication and data storage are essential to protect sensitive information.
3. Scalability
As your app grows, it needs to handle an increasing number of users, messages, and multimedia files without performance degradation. Implementing a scalable infrastructure (e.g., cloud services, NoSQL databases) is crucial to ensure smooth operation even during traffic spikes.
4. Push Notifications
Push notifications are key to engaging users and notifying them of new messages. Ensuring that notifications are delivered in real-time and work seamlessly across multiple devices (iOS, Android, Web) can be challenging, particularly in managing device configurations and user preferences.

UIKit SDK Integration
To create chat applications, we must first incorporate the Chatkit SDK into our project. To accomplish this, follow the steps below:
Step 1: Log into the ZEGOCLOUD developer console.
ZEGOCLOUD’s developer console makes app creation easy. First, log in or signup to access ZEGOCLOUD’s admin console to integrate the chat functionality using ChatKit.
Step 2: Create a new project
To begin our chat app creation process, click “Create new project.”
When you click the “Create new project” button, you’ll be asked to choose the type of app you want to build. Because we’re using the Call Kit, select “Video and voice” and click “Next.”
Step 3: Select the project’s name.
Following the creation of a project in step (2), the next step will be to name our application.
Please keep in mind that you can only name a project with digits, letters, and underscores ( ).
Step 4: Pick a way to build the UI.
There are two ways to build UIKit on ZEGOCLOUD. You can use the pre-built UIKit, which will give our one-on-one video call app responsive UI right out of the box. If you need more freedom to change things, you can choose SDK-level UI customization.
Step 5: Select a platform and obtain configuration files.
I’ll go with “Web” as my platform of choice. If you require iOS ChatKit and Android ChatKit, you can also select Flutter or React Native ChatKit.
Step 6: Download project.
To download project files, click “Get configuration and integration files.”
Run a demo.
Open app with any modern web browser of choice.
