This is the fork in the road. Everything after it follows from this one answer, so take a minute over it.
You describe what you want in a chat box. The tool builds the screens, the database and the login, then hosts it. You get a URL.
You type "a booking site for my dog-grooming business with a calendar and email confirmations" and watch an app appear over about ninety seconds. Then you spend two hours refining it by asking for changes.
Every serious builder syncs to GitHub. Turn that on from day one — it costs nothing and it is what lets you graduate later.
A real code editor with an AI agent inside it. You open a project folder, describe a change, and watch it edit the files. You can always take over.
It looks like a normal code editor. You highlight something, hit a shortcut, describe a change and approve a diff. Over a few weeks you absorb a surprising amount without formally learning to code.
The common path in 2026 is: prototype in a builder, export to GitHub, finish in an editor. If you already know you want to build more than one thing, starting here saves you the migration.
An agent that lives in your terminal with no interface at all. It reads and rewrites your whole codebase, runs commands and tests its own work.
A black window. You type a paragraph describing what you want. It thinks, reads twenty files, writes to eight of them, runs the tests, fixes what broke, and tells you it is done. It is startling the first time.
If you have never used a terminal, this is not where to start. Come back in a month.
Prototype in a builder because it is fast, sync to GitHub, then finish in an editor when the builder starts fighting you. The pattern most experienced builders converge on.
Builders are dramatically faster for the first 70–80% of a project — layout, screens, the basic shape of the thing. They get expensive and frustrating for the last 20%, which is where the fiddly logic lives. Editors are the opposite.
Two subscriptions if you run both at once — around $45/mo. Or use the builder's free tier for the prototype and only pay for the editor.
