Frequently asked questions
Is Coddy free?
Yes. Coddy is completely free to start. You can take dozens of interactive courses, build coding streaks, and earn XP without paying anything. We also offer an optional premium plan with extra features for learners who want more.
How long does it take to learn to code?
Most beginners can write useful code within 1 to 2 months of consistent daily practice. Reaching a job-ready level usually takes 6 to 12 months. Our free roadmaps for software engineering, frontend, backend and data analysis lay out that road course by course. With Coddy's gamified streaks and bite-sized lessons, you can make steady progress with as little as 15 minutes a day.
How hard is it to learn to code?
Coding is a learnable skill, not a talent. Most beginners feel lost in the first few weeks, and that's normal. The trick is short daily practice instead of long weekend sessions. Coddy's bite-sized lessons and gamified streaks are built specifically to make sticking with it easy.
Where can I learn to code for free?
Right here on Coddy. We offer free interactive courses across 20+ programming languages (Python, JavaScript, SQL, HTML, CSS, Java, C, Go, and more), taught through hands-on lessons with an in-browser code editor and Bugsy, an AI tutor that helps when you get stuck.
What programming language should I learn first?
For most beginners, Python is the easiest language to start with: it reads almost like English and is widely used in web development, data science, and AI. If web design is your goal, start with HTML, CSS, and JavaScript. Already have a job in mind? Pick a roadmap instead: it chooses the languages and their order for you. Not sure which to pick? Our short onboarding questionnaire asks a few quick questions about what you want to build and recommends the right language for you. Try it on the Get Started flow.
Can I get a certificate from Coddy?
Yes. Every course you complete on Coddy comes with a verifiable certificate. You can download it as a PDF and add it directly to your LinkedIn profile or résumé to showcase the skills you've earned.
