Questions & Answers

As answered by people managing DailyCoding.dev and CodeSignal.

What makes your product unique?

DailyCoding.dev's answer

One challenge per day, and it is the same challenge for everyone. There is no catalogue to browse and nothing to pick, that decision is exactly what makes most people quit after a week. Once you submit, every other solution to the same challenge becomes readable, across all 11 languages.

Why should a person choose your product over its competitors?

DailyCoding.dev's answer

Because it takes choice away instead of adding more. LeetCode and Codewars offer thousands of problems; Daily Coding offers the one that is live today. It is free with no paid tier, today's challenge works without an account, and the whole thing is open source under MIT, including the sandbox that runs the code.

How would you describe the primary audience of your product?

DailyCoding.dev's answer

Developers who want a small daily habit rather than interview grinding: people who enjoy Advent of Code and miss it in January, students and apprentices practising algorithms, and experienced developers warming up in a language they are currently learning.

What's the story behind your product?

DailyCoding.dev's answer

I do Advent of Code every December and try to keep the habit going on LeetCode every January. It never lasted more than a week, too many problems, no reason to do this one today. So I built what I actually wanted: one challenge, the same for everybody, all year round. Seven months of evenings and about 470 commits later, it runs in 11 languages.

Which are the primary technologies used for building your product?

DailyCoding.dev's answer

Next.js 16 and TypeScript with the Monaco editor, deployed on Vercel. Submissions are executed on a self-hosted Piston instance on a Hetzner server, with typed test harnesses generated per language. Prisma for data access, Postgres DB
