In case you are looking to integrate video SDKs into your existing web or mobile apps, then below are a few basic steps to consider that might help you kickstart your implementation goal.

Here are a few basic steps to build a video chat app:

1. Research who your users are and understand their needs and requirements.

2. Upon gathering requirements, decide on your investments and costs. If you are thinking of building an app from scratch, planning on infrastructure costs, and more, think of investing in a one-time license cost or the pay-as-you-go model.

3. Decide on which video features to add, like video conferencing, group video calls, recording, and more that most of the users love to see.

4. Now think about the tech stack and platforms.

5. Consider implementing an engaging UI that is smooth and elegant. In case you find it difficult, simply opt for Mirrorfly, which offers pre-built UI kits for Android and iOS apps

Plus, make sure that you adopt consistency throughout your app. And now we will see what features Twilio has kept that have been drawing users to it.

2. Signal Protocol to provide multi-end encryption across multiple clients

3. Hosting data on-premises to take full ownership of data and security

4. Using MFA to prevent unauthorized access

5. Staying compliant with HIPAA and GDPR

So that was all the features and security parameters to consider. Now, if you are thinking about where you can find all these, go ahead with MirrorFly.
