Quick answer
Rainbow Web Designers builds custom web applications from R45,000: client portals, admin dashboards, booking and ordering platforms, internal tools and startup MVPs. Projects start with a R4,500 discovery sprint that is credited to the build, and most apps launch in 6 to 12 weeks.

Notifications, reminders and chatbots connected to your data.
MVPs for startups
A focused first version you can put in front of customers and investors.
How our web development process works
1. Discovery sprint (R4,500, credited to your build). We map users, features, screens and integrations, then give you a fixed price and timeline. You keep the documents even if you do not proceed.
2. Design. Clickable screens you can test with real users before development starts.
3. Build in weekly releases. You get a live staging link and see progress every week, not just at the end.
4. Launch and support. Hosting, monitoring, backups and ongoing improvements on a monthly care plan.
