I built CoderScreen, the open-source platform for live coding interviews and coding assessments.

Most existing tools in this space (like CoderPad or HackerRank) feel like they’re built for enterprise sales teams, charging thousands per year for something that should be fast, simple, and developer-friendly.

Key Features:

- Real-time collaborative code environment

- Fast, sandboxed execution in 10+ languages

- Entirely open-source and self-hostable (on Cloudflare)

Coming Soon:

- Web development environments (React, Vue, etc)

- Coding assessments

- Take home projects

I’m actively looking for teams to try it out, give feedback, and help shape what comes next. If you're hiring engineers or have thoughts on what’s missing, I’d love to hear from you.

Thanks, Kuba
