When this matters
Endpoints matter whenever AI gives you a curl command, a fetch example, or docs that say “POST to this URL.” If you hit the wrong endpoint, use the wrong method, or send the wrong payload, nothing good happens.
Small example
One API can expose several endpoints, each with its own job.
GET /api/projects -> list projects
POST /api/projects -> create a project
GET /api/projects/123 -> fetch one projectCommon mistake or lookout
Thinking the base URL is the endpoint. `https://api.stripe.com` is not the same thing as the exact path and method you need for a charge, customer, or webhook operation.
Why this matters for vibe coders
Vibe coders often wire APIs by copying snippets quickly. Knowing what an endpoint is helps you debug whether the problem is the URL, the HTTP method, the headers, or the body instead of just muttering “the API is broken.”

Secure Your App
You don’t need a full security department for your vibe-coded side project, but you do need to fix the obvious stuff before bots discover it for you.

Comparison
Lovable vs Antigravity for Vibe Coders
These both sit in the “build with AI” bucket, but they solve different first problems. Lovable is the faster path from idea to deployed web app. Antigravity is stronger when you want agents operating inside real repos with more verification, control, and orchestration.
Comparison
Supabase vs Firebase for Vibe Coders
These are two of the fastest ways to bolt a real backend onto an AI-built app, but they optimize for different futures. Supabase is usually the cleaner default for SQL-first web apps. Firebase is still brutally effective when mobile support, post-launch tooling, and the wider Google app ecosystem matter most—and it now has a real Postgres path through SQL Connect.
