Full explanation
No-code tools let you build websites, apps, and automations using drag and drop, forms, and simple settings. No programming required.
Webflow, Bubble, Airtable, and Zapier are popular no-code tools. They make it possible for non-technical founders to ship real products fast.
The trade-off is that you depend on the platform. You usually cannot export the code, and you pay the tool forever.
Concrete example
You build a marketplace for yoga teachers using Webflow for the design, Airtable as a database, and Stripe for payments. You never touched code.
