Frequently Asked Questions
How much does it cost to build an app like WhatsApp?
On a messaging base we've already proven, a WhatsApp-style MVP — 1:1 and group chat, media, presence — typically starts in the lower five figures. Voice and video calling plus end-to-end encryption add to that. Send your requirements for a free quote.
How long does it take to build a WhatsApp clone?
A branded messaging MVP on the tailored foundation generally takes 8-12 weeks. A full app — group video calls, encryption, multi-device sync — needs 3-5 months, run as agile sprints with demos every two weeks.
Is the messaging really end-to-end encrypted?
It is. Messages and media are end-to-end encrypted, so only sender and recipient can read them. Disappearing messages, secure backups and configurable data retention are all available on top.
Does it support voice and video calls?
Yes — one-to-one and group voice and video over WebRTC, with dependable signalling, presence, and push notifications covering reconnections and missed calls.
Do I own the source code?
Yes. The source code and infrastructure are entirely yours, no vendor lock-in, with optional ongoing maintenance and support if you'd like it.
