Share This Post

Chat SDK provides a simple and user-friendly UI. It also ensures that all messages are delivered securely. To select a chat solution, first outline why your product requires chat functionality. This will empower you to seek API/SDKs that excel in this area.


While chat may seem simple, reliable in-app messaging requires many technical components and engineering resources. As a result, building chat in-house can consume more development bandwidth than an entire product if you don’t carefully prioritize it relative to your core value proposition.

When choosing a chat API or SDK, you want one with detailed documentation that’s easy to understand. This ensures that SWEs can quickly pick up on using the feature without relying on support.

You also want to be sure that the chat solution adheres to industry-standard security practices and will protect user data. Otherwise, you risk becoming another data breach headline or facing fines for mishandling customer information. Choose a vendor like with robust security features like end-to-end encryption, source code control, and security patches to ensure your apps are safe. A secure in-app messaging platform will keep users’ conversations private and prevent the leaking of personal information.


A reliable chat solution should offer robust real-time messaging functionality and the ability to expand as your needs change. It should also support a range of programming languages and platforms, 3rd party integrations, and multi-protocol capabilities.

The right solution offers a variety of Chat APIs and SDKs that provide developers with the tools to add in-app messaging to their apps, including direct and group messages, threads, reactions, typing indicators, and more. Its UI/UX Kits enable customizability and ease of integration. Some also provide developers with tools to help productive app communication. Its chat APIs and SDKs are easily integrated into existing web-based or mobile-native systems.

Furthermore, a trustworthy chat solution should put security first to guarantee the privacy and accuracy of communications. It should provide end-to-end encryption and adhere to industry standards. Furthermore, it should have a responsive customer support system to promptly address issues or concerns, contributing to a trustworthy and efficient communication platform.


Users use chat apps daily, so product teams must ensure the system can handle many messages and users. This is where a Chat SDK can help.

While an API-based chat solution may require heavier integration work by developers, it can also save time and resources in the long run. In addition, it can offer a customizable user experience and robust security features such as end-to-end encryption and compliance with industry standards.

Additionally, real-time Chat SDK tools offer multiple monetization options like in-chat payments and sponsorships, which can turn your chat into a revenue-generating resource for your company. Furthermore, these systems are designed to scale and allow for unlimited concurrent users, which can prove helpful in the case of business expansion. In contrast, subscription-based chat solutions limit simultaneous users on a per-plan basis. 

Moreover, a scalable Chat SDK should provide efficient load balancing and server-side optimizations, ensuring optimal performance even during peak usage. This capability is essential for accommodating sudden spikes in user activity and maintaining a seamless user experience. Additionally, a well-designed Chat SDK should facilitate easy integration with third-party analytics tools, empowering businesses to gather insights into user behavior and further enhance their scalability strategies.


The best chat SDK should provide robust security features to keep users’ conversations and data private. This can include end-to-end encryption, securing the server-side components with Transport Layer Security (TLS), or other data protection mechanisms.

In addition, the SDK should be able to handle large volumes of traffic without breaking down. This can be done by implementing multiple connections to the chat servers, using load balancers, or using other scalable solutions.

Moreover, the SDK should be capable of saving chat messages to prevent losing important information. This is important because it allows developers to comply with industry-standard data protection regulations and protect against security breaches. This can be achieved by integrating chat providers offering unlimited user data storage. The right tools allow indefinite chat message retention.


Pricing is a major factor in choosing an SDK or API solution. For some apps, the savings in up-front cost and development bandwidth will make it a no-brainer to use a chat SDK. But in-house development may be worth the investment for others, particularly those with a unique vision for how a chat should look and function and the budget to back it up.

Stream offers a developer-friendly SDK and UI kit to help brands build productive communication features into their mobile and web apps. It supports direct, group, and channel messaging with threads, read receipts, and reactions. Plus, it provides advanced features like online presence, profanity control, and user moderation.

Its security features protect sensitive data and conversations from eavesdropping. It also complies with GDPR and other privacy standards to keep users’ data secure. It is ideal for e-commerce, marketplace, healthcare, and finance industries. This chat API is a reliable, scalable, and customizable option for businesses of all sizes. It integrates easily and is available on a variety of platforms.
