Practice. Learn. Transform.
Codekra is a platform for improving your coding skills — curated problems, daily challenges and guided learning paths that take you from fundamentals to advanced topics, so you can practise, learn and get hired.
Help every developer get better at solving problems
Getting better at coding takes more than reading tutorials — it takes deliberate, consistent practice on the right problems, in the right order.
Codekra brings that together in one place: problems grouped by the patterns that matter, learning paths that build on each other, and an editor that lets you test ideas immediately.
Everything is designed to help you ship real skills — to recognise a problem, reason about it and write a working solution with confidence.
What you can do on Codekra
Everything you need to practise, learn and track your growth as a developer.
How it works, step by step
From your first visit to a daily practice habit — here's the path most learners follow.
- 1Step 1Create your free account
Sign up with your email so Codekra can save your progress, completed lessons and stars across devices.
Sign up → - 2Step 2Choose where to start
New to a topic? Pick a learning path and follow it module by module. Already comfortable? Jump into the problem list and filter by topic or difficulty.
See learning paths → - 3Step 3Read the problem carefully
Each problem has a description, examples and constraints. Work through the examples by hand first — it's the fastest way to spot the pattern.
Open a problem → - 4Step 4Write and run your solution
Pick your language, write code in the editor and run it against your own input. Iterate until the output matches what you expect.
Try the editor → - 5Step 5Complete lessons and earn stars
Finish lessons in your learning path to mark them complete. Every completed lesson adds points, and your stars decide your rank.
View the leaderboard → - 6Step 6Build a daily habit
Come back for the daily challenge. Small, consistent practice beats occasional cramming — and the archive is there if you miss a day.
Today's challenge →
Built for every stage of your journey
Build strong fundamentals in data structures and algorithms, one topic at a time.
Practise the patterns that come up again and again in coding interviews, under realistic conditions.
Keep your problem-solving sharp and pick up new areas like graphs, dynamic programming or system design.
Our principles
You learn to code by writing code. Every concept leads to a problem you can solve right away.
Problems and lessons are organised by pattern and difficulty, so you're never guessing what to do next.
Daily challenges, progress tracking and streaks reward showing up a little every day.
The goal is to recognise patterns and reason about solutions, not to remember answers.
Frequently asked questions
No. Codekra runs entirely in your browser. You write and run code in the built-in editor.
