Frequently Asked Questions
Have questions? We have answers. Here are some of the most common inquiries we receive about building a Telegram-like application.
How long does it take to build an app like Telegram?
The timeline varies based on complexity. A core-feature MVP can be developed in 3-5 months. A full-featured application with advanced security and cross-platform support typically takes 6-9 months. Our AI-augmented processes can often accelerate these timelines.
Will my app be secure and private?
Absolutely. Security is our top priority. We implement end-to-end encryption using established protocols like Signal.
