The Vibe Coding Glossary: Every Term in Plain English

This glossary defines every term you'll actually meet while building your own website or app with AI — in one or two plain sentences each, with zero assumed knowledge. Vibe coding platforms hide most technical complexity, but the words still leak through: the pricing page says "credits," the settings say "DNS," the AI says it "deployed your app." Knowing 30 terms is genuinely all you need to build with confidence — and to see through hype when you meet it.

Terms are grouped by when you'll meet them: choosing a platform, writing prompts, understanding what got built, going live, and reading the news. Skim now, return when a word bites. And if a platform or article uses a term this page doesn't cover, that's usually a sign you don't need it.

Key takeaways

• You need ~30 terms, not a computer science degree. This page is the complete list.
• The money words: credit, message credit, token — related units that different platforms define and charge differently.
• The building words: frontend (what visitors see), backend (what runs behind), database (where information lives), authentication (logins).
• The going-live words: deployment, domain, DNS, SSL — all mostly handled for you.
• The caution words: hallucination, technical debt, lock-in — know them and you're a smarter buyer than most.

Choosing a platform

Vibe coding — building software by describing it in plain language while AI writes the code. Coined by Andrej Karpathy (2025), Collins Word of the Year 2025. Full guide.

AI app builder — a platform (Base44, Lovable, v0) that turns descriptions into complete, hosted applications. What most non-coders mean when they say vibe coding.

AI coding assistant — a tool for people who already program (e.g., Cursor); it accelerates writing code rather than replacing the need to read it.

No-code / low-code — the previous generation: visual template builders (drag-and-drop). Simpler ceiling, less flexibility than AI generation.

LLM (large language model) — the AI engine (like the models behind ChatGPT or Claude) that reads your description and writes the code. Platforms swap and upgrade these under the hood.

Free tier — a no-payment entry plan. It is your best evaluation tool, but publishing, traffic, runtime and custom-domain limits differ by platform.

Paying for it

Credit — a platform-defined unit or balance for AI work. Lovable uses build credits, while v0 draws generation from a dollar-denominated credit balance; one platform's credit is not comparable with another's.

Message credit — Base44's flavor: one build instruction = one message credit. Its integration credits are different — consumed when your live app does things (sends email, calls AI).

Token — how AI work is measured at the raw level (roughly, chunks of text the AI reads and writes). Bolt meters building with tokens; v0 uses a credit balance even though the underlying models still process tokens.

Rollover — unused credits carrying into next month. Check for it if you build in bursts.

Usage-based pricing — pay for what you consume beyond the plan's allowance. Flexible, less predictable — costs guide.

Talking to the AI

Prompt — any instruction you give the AI. The core skill of vibe coding is writing clear ones.

Master prompt — our term for the one complete, structured first prompt (about → design → pages → forms) that builds most of your project in one shot. Every playbook contains one.

Iteration — the refine loop: look at the result, request one specific change, repeat. Where projects are won.

Context — what the AI currently "knows" about your project. Long chaotic conversations muddy it; fresh, complete re-descriptions clean it.

Hallucination — when AI states something false with confidence — in code, inventing a feature or claiming something works when it doesn't. The antidote: test what you ship (step 6 of our process guide).

What actually got built

Frontend — everything visitors see and click: pages, buttons, forms.

Backend — the machinery behind the curtain: processing form submissions, checking passwords, saving orders.

Database — where your app's information lives permanently: contacts, products, bookings. Some builders include a native database; others connect a provider. "Stored in a database you can inspect and back up" is the phrase to look for.

Authentication (auth) — the login system: accounts, passwords, "who is allowed to see what." Use the builder's native or recommended provider-backed auth path; never improvise password storage yourself.

API — how software talks to other software; when your app "connects to Google Maps," an API is doing it.

Integration — a pre-wired connection to an outside service (email sending, payments, maps) so you don't wrestle APIs yourself.

Responsive — a layout that adapts to phone screens. Non-negotiable; test on your phone before launch.

Code export — taking the generated source code into Git or another development environment. Lovable and v0 have strong conventional handoff paths; Base44 also exposes frontend code, GitHub, CLI and SDK workflows, while its managed backend and production data require a separate migration plan.

Lock-in — how hard leaving a platform would be. Less scary than the YouTube thumbnails claim, but worth knowing before you build deep.

Going live

Deployment — publishing your app to the internet. On these platforms: a button.

Hosting — the infrastructure that serves your site to visitors. These builders provide a managed publishing path—v0 through Vercel—but plan allowances, traffic, runtime services and connected providers can still affect cost.

Domain — your address (yourbusiness.com), bought separately for ~$10–20/year and connected in settings.

DNS — the internet's phonebook, pointing your domain at your site. You'll meet it once, during connection, and it takes up to a day or two to update. Patience, not panic.

SSL / HTTPS — the padlock; encrypted traffic. Platforms handle it automatically — if a tool asks you to buy an "SSL certificate," walk away.

SEO — making your site findable on Google: page titles, descriptions, real content with the words your customers search.

Reading the news like a skeptic

MVP (minimum viable product) — the smallest launchable version. Vibe coding's natural unit: ship it, learn, grow it.

Technical debt — shortcuts that cost later; in AI building, usually a pile of patch-on-patch corrections. Paid down by fresh re-describing (see context).

Agent / agentic — AI that performs multi-step tasks on its own ("build the page, then wire the form"). The direction everything is moving; also 2026's most abused marketing word.

Full-stack — frontend + backend + database together, i.e., a complete application. "Full-stack generation" = the platform builds all three from your prompt.

Thirty terms, zero gatekeeping — the vocabulary was the last excuse. Find your profession's playbook and put the words to work. You can build this.
