Learn to build.
One bite at a time.
devai.io is a growing library of tiny, hands-on coding tutorials for complete beginners. Each one is a real, working mini-app you can read in a sitting — a tip calculator, a live weather lookup, your first API call. No jargon, no setup, just build something that works.
Your first few wins
Brand new? Start with one of these. Each takes minutes and ends with something that actually works.
Two ways to begin
Start with the building blocks of every web page, or jump straight to pulling real data off the internet.
Pick. Run. Tinker.
There's no course to sign up for and nothing to configure. You learn by building the smallest real thing, then changing it.
Pick a tutorial
Browse by track. Every tutorial teaches one idea — a tip calculator, a live weather lookup — through a small, real example you can finish today.
Read it, run it
Open the code right on the page, or download the zip. Most tutorials run by double-clicking a single file — no installs, no setup, no accounts.
Change one thing
Every README ends with 'try changing this.' Tweak a number, swap a color, add a field — the fastest way to learn is to break something and fix it.
Level up to the real thing
Once the basics click, keep the same site going. The advanced track is a set of production-grade starters — auth, billing, APIs, dashboards — extracted from real, deployed apps. The same code that runs in production, ready for you to grow into.
Build your first thing today.
Pick a tutorial, open the code, and have something working in the next ten minutes.
