What is vibe coding? A plain guide for people who want to ship15 October 2026 · 3 min readVibe coding is building software by describing what you want in plain words and letting an AI write the code. You say "a booking page for my salon, with a calendar and a form that emails me", the AI writes it, you look at the result, and you say what to change next. You steer by what you see, not by reading every line.The phrase took off in 2025, and by now it covers a whole category of tools: AI app builders like Lovable, Bolt, Base44, v0 and SPOE, and AI coding assistants inside code editors. They differ a lot in what they hand you at the end. That difference matters more than any feature list, and it is the part most people only notice when they try to leave.What vibe coding is good atGetting from idea to something real, fast. A landing page, a booking tool, an internal dashboard, a prototype to show an investor: things that used to take a developer a week now take an afternoon of describing and adjusting.Letting people who know the problem build the tool. A clinic manager knows what the intake form needs. A tradie knows what a quote has to say. Vibe coding lets them build it directly instead of explaining it to someone else.Trying ideas cheaply. When a version costs minutes, you can try three layouts and keep the one customers actually use.Where it goes wrongThe weak spots are not where most people expect. The AI is usually good at making something that looks right. The trouble is underneath.Security slips. An AI writing quickly will sometimes put a secret key in the code, build a database query by pasting text into it, or leave a page that changes data open to anyone. These are the classic mistakes, and they do not show up on screen.Big apps drift. Each change is written by a model that is reading the whole project. As the project grows, a change in one place can quietly break another.Lock-in. This is the one that bites later. Some builders run your app on their own infrastructure, with their own database and their own login system, and the code they let you download does not run anywhere else without a rewrite. Two builders closed this year: Mocha shut down on 1 August 2026, and Firebase Studio closes on 22 March 2027. Their users have had to work out what they actually own.How to vibe code without getting burnedYou do not need to read code to protect yourself. You need to ask a few questions of whatever tool you use.

Can I download the code, and does it run without you? Not "is there an export button", but "does the export start on my own machine with standard tools". If the answer involves the builder's own packages or servers, you are renting, not owning.

Where does my data live? A standard database you can copy is portable. A proprietary backend is not.

Who checks the AI's work? The same model that wrote the code is a poor judge of it. A second check, ideally by a different model, catches what the first one misses.

Can I undo? Every change should be a version you can roll back in one click.

What does it cost when it fails? Some tools charge for a build that broke. Look for an estimate before you send, and no charge for failures.

How SPOE does itSPOE was built around those questions. You describe the app, and it is built into a real project: a Next.js, Fastify and Postgres app, or a plain HTML website if that is all you need. A second AI from a different model family reviews every change before it lands, and anything it flags waits for you. Every change is a version you can undo.When you are done, you export everything: the code, the database schema, Docker files and a signed certificate of where each file came from. It starts with docker compose up and has nothing of SPOE inside, so it runs on your laptop, your server or any cloud. Your first payment of any size unlocks export for good, and your code is always visible in the editor either way.You can start free with 250 credits, no card. Or see what it costs first.The short versionVibe coding is real and useful. Use it for what it is good at, and before you build anything you care about, check that you will be able to take it with you. The best time to find out a tool will not let you leave is before you start, not the week it announces it is closing.Pricing · Blog · App ideas · Compare builders · Verify an export · Developer API · Start freeThis page needs JavaScript to run the app itself.
