Sailop vs Prettier: Formatting vs Design Quality

What Prettier does

Prettier is an opinionated code formatter. It parses your code into an AST and reprints it with consistent formatting -- indentation, line width, semicolons, trailing commas. The code logic stays identical; only the whitespace changes.

const x={a:1,b:2,c:3}
function foo(  ){
  return x.a+
  x.b}

const x = { a: 1, b: 2, c: 3 };

function foo() {
  return x.a + x.b;
}

Same logic, same output. Only the formatting changed. Prettier never touches your design decisions.

What Sailop does

Sailop analyzes the visual patterns in your frontend code. It does not care about indentation or semicolons. It looks at what your site will actually look like in a browser and asks: does this look like AI generated it?

font-family: Inter, sans-serif;
color: #3b82f6;
border-radius: 0.5rem;
transition: all 300ms ease;
background: #ffffff;

font-family: Bitter, Georgia, serif;
color: #c2592e;
border-radius: 7px;
transition: transform 450ms cubic-bezier(.34,1.56,.64,1);
background: #f5f0eb;

Different visual output. The layout logic stays the same -- only the design tokens change. Your site stops looking like every other AI-generated project.

Complementary tools

Prettier and Sailop never conflict because they operate on different layers entirely. Prettier handles source code formatting. Sailop handles visual design patterns. Run them in any order:

Verdict

Prettier asks "is this code formatted consistently?" Sailop asks "does this design look like AI generated it?" There is zero overlap. Use Prettier for clean code and Sailop for a clean visual identity.
