Frequently Asked Questions
How much does it cost to build an app like WhatsApp?
Starting from a proven messaging base, a WhatsApp-style MVP with 1:1 and group chat, media and presence typically starts in the lower five figures. Voice and video calling and end-to-end encryption add to it. Send your requirements for a free quote.
How long does it take to build a WhatsApp clone?
A branded messaging MVP on our tailored foundation is usually ready in 8-12 weeks. A full app with group video calls, encryption and multi-device sync takes 3-5 months, delivered in agile sprints with demos every two weeks.
Is the messaging really end-to-end encrypted?
Yes. We implement end-to-end encryption for messages and media so only sender and recipient can read them, and we can add disappearing messages, secure backups and configurable data retention.
Does it support voice and video calls?
Yes. We build one-to-one and group voice and video calling over WebRTC with reliable signalling, presence and push notifications for reconnection and missed-call handling.
Do I own the source code?
Yes. You get full ownership of the source code and infrastructure with no vendor lock-in, plus optional ongoing maintenance and support.
