01
Exact
Every number on the page is computed from the input in front of you. Sample fixtures are labeled as samples.
01 The bench
A directory,
kept exact.
Benchline is a directory of exact tools at benchline.fabwaseem.com. 82 tools, 31 categories, 70 of them entirely in the browser.
02
Private
Local tools run in the tab. A fetch happens only when the tool’s job is to read a public URL, and only that URL.
03
Fast
The directory is static HTML. Each tool loads as its own chunk when you open it.
04
Current
Model prices carry a checked date. Specs link to the canonical document, not a paraphrase that drifts.

Benchline
An independent tool bench. The source is public, the registry is generated, and the prices say when they were last checked.
