I Got Tired of Waiting for the Right Coding Platform — So I Built It

Like many Computing teachers, I relied heavily on platforms like Replit and Coding Rooms. They were fast, flexible, and perfectly suited for KS3 and GCSE coding lessons.

Until they weren’t.

• Replit changed its education model

• Coding Rooms removed their free plan

• Suddenly, we were scrambling for viable alternatives

These changes made me realise how dependent I’d become on tools that weren’t built specifically for our classrooms — or our constraints as UK teachers.

So I started building one.

Introducing CodeBash

CodeBash is a browser-based coding platform designed for UK secondary schools. It’s shaped entirely by classroom experience and curriculum demands, not just generic coding features.

This isn’t meant as a replacement for every platform — but it is designed to solve the specific problems I and many others have faced.

What Makes It Different?

• Curriculum-aligned tasks (KS3 and GCSE)

• Auto-marking with real-time code execution

• Simple class setup with join codes and bulk task assignment

• Student progress tracking and alerts when students get stuck

• GDPR-compliant with private, school-controlled accounts

• Optional AI-powered feedback (designed with safeguarding in mind)

Why Share This Here?

I’m sharing this on CAS not to market, but to invite feedback and ideas from fellow educators. This is a platform by teachers, for teachers — and that means it only works if it genuinely solves problems in real classrooms.

Join the Pilot

I’m inviting a limited number of schools to pilot CodeBash free for one half term starting this September (or earlier, if you’d like to try before term ends). Pilot schools will get:

• Full access for staff and students

• Curriculum-ready coding tasks

• Support and walkthroughs

• A say in shaping new features

• Recognition as early partners

Final Thoughts

If you’ve faced the same frustrations I have — platform changes, student data worries, gaps in curriculum support — I’d love to hear how you’ve adapted. If CodeBash sounds useful, even better — I’m looking for schools to test it and help shape what comes next.
