Readymade WhatsApp Clone or Custom Build — Messaging App (Mobile + Desktop + Browser)
Budget: £250 – £750 GBP
We're looking for a developer or team to help us acquire and customise an existing WhatsApp-style chat application to match our specific requirements — rather than building entirely from scratch.
Preferred approach:
We're open to purchasing an existing app/source code (e.g., from marketplaces like CodeCanyon) that already covers most core chat/calling functionality, and having a developer customise it to add our specific requirements below. If no suitable existing solution can be adapted, we're also open to a fully custom build — please indicate which approach you'd recommend and why.
What we need, either way:
1. Desktop & Mobile Connection
Users start their computer, open the mobile app, and scan a QR/barcode to connect the desktop app — similar to WhatsApp Web
Android, iOS, and desktop versions required
2. User Registration & Accounts
Sign up via email address, with First Name and Last Name
Accounts created under our brand
System auto-generates a unique username and password
Other users only see the full name; users are searchable by unique username once shared
3. Key-Based Access System
App launch shows "Enter Key" or "Get Key"
Only Admin can create, issue, and manage access keys
Please advise on best architecture for multi-device key management
4. Messaging
Real-time text messaging and file sharing
Only Admin can delete messages/conversations — not regular users
5. Calling
App-to-app voice/video calling
Admin controls who can call whom — some users can call each other, others cannot unless granted permission
6. Groups
Only Admin can create groups and add/remove members
7. Recording & Monitoring
Conversation recording with noise cancellation
Automatic screenshot capture at set intervals
Secure, access-controlled storage for recordings and screenshots
8. Notifications
Push notifications and real-time updates
9. Deployment
No public App Store/Play Store submission — private/enterprise distribution only (Apple Business/Enterprise Program for iOS, direct APK/private distribution for Android)
SDK/source code access required so we retain full modification rights
How to apply — please include:
Whether you'd recommend buying-and-customising an existing app or building custom, and why
If recommending an existing app: which one, and a link/demo if possible
Your experience with similar projects (messaging apps, admin-permission systems, key-based access, multi-device apps)
Recommended technology stack
Fixed price and realistic timeline (please break down by phase if possible)
Any questions on system design — particularly around key management, QR pairing architecture, or the recording/screenshot implementation
Budget: Open to proposals — please quote based on the scope above.
Timeline: Flexible, but please provide a realistic estimate.
Contract: Freelance, with an NDA and IP protection agreement.
