the npm scale that knows your sins
Bundlephobia, with teeth. Drop in any npm package and we'll tell you what it really costs — minified, brotli'd at quality 11, and the entire transitive dep tree drawn out in wires.

▍the language
three operators
react- a single package
react+vue- two combined — sum the weight
react|vue- two compared — one column each
react+react-dom | vue | svelte- three columns, first is a combo
(react+vue) | svelte+kit- parens, in case precedence isn't obvious
+ binds tighter than |. Same shape as && binds tighter than || in your code.
▍what you get
three things
01
real bundles, real brotli at quality 11. no webpack-stats math, no estimates.
02
tree for the meticulous, wire-graph for the dramatic. every transitive dep weighed.
03
weigh real-world combos in one shot. shared deps light up amber so you see the double-pay.
