Sololearn built one of the biggest communities in learning to code, and we have not tried to copy it. Devpuff puts a real development workspace where their forum sits. Here is the honest difference.
Sololearn built something real: one of the largest mobile communities of people learning to code, with courses, discussion threads, and code battles keeping it alive. If a crowd is what keeps you accountable, it earns its place on your phone. Here is the honest map of the differences.
Sololearn is social-first. Devpuff is workspace-first.
Sololearn surrounds lessons with people: questions, comments, competitive quizzes. Devpuff surrounds you with a development environment: a real editor, live preview, a console, and projects graded by checks. Our "keep going" pressure comes from streaks, diamonds, and weekly leagues rather than forums.
That is a genuine fork in the road, not a feature gap. Some people are pulled forward by other people. Some are pulled forward by the work. Pick the one that describes you.

Community, plainly. It is their moat and we have not tried to dig one like it. Forums, comments, code battles, a place to ask a stranger why your loop will not stop. Devpuff's social layer is deliberately light, which is a polite way of saying we do not have that.
If you learn out loud, by asking mid-lesson, comparing answers, and racing someone through a quiz, they built the product for you and we did not.
Your daily reps happen in something that behaves like a real dev environment. A real editor, a live preview, a console, multi-line code, projects graded by actual checks rather than a right-answer button.
An AI tutor instead of a queue. Puff reads your current code, your last output, and your failing check, and answers now. A forum is a wonderful thing and it is also asynchronous. At 11pm, on lesson four, stuck on a typo, "now" is the feature.
Certificates with receipts. Any completion certificate is mostly a signal to yourself. Ours at least come with a public verification link and your measured performance, so someone checking has something real to look at.
You can try it before signing up. There is a live editor on every course page. Run something before you decide.
Pick Sololearn if you learn best in a crowd, asking questions mid-lesson, comparing answers, and battling strangers over quiz speed.
Pick Devpuff if you learn best by building, and you want the thing you open every day to look like the thing professionals use. An editor, a preview, a console, an AI that debugs alongside you, and a certificate that shows how you did.
Our first lesson is free and there is an editor on every course page. Five minutes tells you whether it clicks.
Where the learning happens. Sololearn is strongest as a mobile app with a big community layer, including discussions, code battles, and social features. Devpuff is a browser-first workspace where the emphasis is writing and running real multi-line code with automated checks and AI help.
Sololearn, plainly. Community is their moat, with forums and social features we have not tried to replicate. Devpuff's social layer is lighter, meaning weekly leagues and streak mechanics rather than discussion boards.
Puff is wired into the workspace. It sees your current code, your last output, and your failing checks, then nudges without spoiling the answer. Sololearn has its own AI features, and how deeply they read your code is best checked on their current product.
Free to start, no credit card required. Write real code from your first lesson and keep your progress forever.
Start Learning FreeAny completion certificate is mostly a signal to yourself. Devpuff's include a public verification link with measured performance, including quiz accuracy, first-try practice rate, and projects shipped, which gives someone checking yours something with substance to look at.
Yes. Every public course page has a live editor with a working console, so you can write and run real code before making an account.
