Why 10xDebuggable exists

The 10x engineer is usually described as someone who types faster or thinks harder. In our experience they are just someone who has seen the failure before. They recognise the shape of a race condition at a glance because they already paid for that lesson once — on a Friday evening, in production.

That is learnable, and it is learnable the boring way: volume. More real bugs, in more real codebases, with someone who tells you whether your fix would have been merged. That is all this site is.

Puzzle platforms are good at one thing: isolated problems with a clean input and a clean output. That is not what engineering days look like. Real work is reading a codebase you did not write, forming a theory about why it misbehaves, and proving that theory with a change small enough to review.

Those skills are hard to practise precisely because they need a whole system, not a snippet — and a system with real scars in it.

Every challenge on 10xDebuggable is a working project you clone and run locally, plus a ticket from its backlog written the way a product manager would write it: business context, observed symptoms, and acceptance criteria you will be judged against.

You fix it on a branch in your own fork, open a pull request, and a human reads the diff. The feedback is what a senior reviewer on your team would have said — not a green checkmark.

10xDebuggable is built and maintained by a small team of working backend engineers. The challenges come from the kinds of bugs we have actually shipped and then had to fix: race conditions, stale caches, N+1 queries, pagination that quietly drops rows.

We review submissions ourselves. That does not scale forever, and that is fine — while we are small, the feedback is better for it.

The platform is in early access and free to use. We are focused on one question before anything else: do developers actually finish these challenges? Everything we build next depends on the answer.

If you have thoughts, gaps, or a challenge you wish existed, tell us. We read everything.
