1. DevProjects by codementor

I just recently stumbled upon DevProjects by Codementor. They have a great collection of challenges you can start on, and add to your portfolio.

Improve your programming skills by working on real-world projects. Join their free community to discuss projects, review code, and learn from peers and mentors.

2. Frontend Mentor

Frontend Mentor has some free coding challenges. But if you pay for their pro subscription, you get access to a lot more.

I currently have enough challenges to do with the free membership :)

I did my first HTML & CSS challenge on Frontend Mentor.

Gain real experience in building websites and providing code reviews. Build your portfolio and help others achieve their goals.

3. freeCodeCamp

I guess everyone knows about freeCodeCamp. It´s still a great resource for learning to code and get some projects for your portfolio.

4. DevChallenges

DevChallenges is a project by Thu Nghiem, with web development challenges and tutorials.

You can choose between three different paths:

• Responsive Web Developer
• Front-end Developer
• Full-stack Developer

Web Development Resources and Community that help you to become a Web Developer by working with Real-life projects and practices.

This is a website that I just discovered through Twitter.
I haven't done any challenges on DevChallenges yet, but I sure will!

Do you have anything to add to the list?
