# Compare

You may already use something that does part of this. Find your tool, or
what you need; each tool says what it is better at, and when to use it
instead. Built from one file (`compare.json`), every row dated and marked
*searched* (checked against a source that day) or *from memory* (not yet
re-checked).

## What we found

No tool we found is open source, keeps edits as data, merges concurrent
moves safely and keeps the page off any server, on a real app. The
nearest are **Builder.io**, shipped and closest in feel, where edits become
code on a hosted service, and **Puck**, whose model of data plus your own
components is ours, for one editor at a time. Not finding a tool is not
proof there isn't one: tell us.
