How Remixware Was Tested: 2880 Planted Copies of Real Open Source Code

Mon, 26 Oct 2026 00:00:00 +0000

A tool that says “this code was copied” has to be right in two directions. It has to find the copies, including the ones that were tidied up, renamed or cut down. And it has to stay quiet about code that only looks like something else, because a report full of false alarms gets ignored. Remixware’s tests measure both, on real open source, and every test and benchmark number here comes from the files the tests write.

Sample Remixware Reports: An Online Shop, a Firmware Project and a Clean One

Mon, 26 Oct 2026 00:00:00 +0000

These are real reports from the test projects that come with Remixware, made by the same commands you’d run on your own code. The projects are small on purpose, so you can read every finding, and each one is planted for a reason: a copy with names changed, a copy with lines edited, a copy that’s credited properly, and code that only looks like someone else’s.

The open source they copy from is a set of small projects written for the tests, under MIT, BSD, ISC, zlib, Apache 2.0, MPL 2.0, GPL, AGPL and no licence at all. Each report was made with remixware scan against an index of those projects.

Why Remixware: Software Built From Other Software

In music, a remix is a new track made from recordings that already exist. The producer takes the vocals from one song, the drums from another, a bass line from a third, and builds something that wasn’t there before. Nobody pretends the parts were recorded from scratch, and when it’s done properly, the people who made them get credit.

Most software is made the same way now. A new program pulls in a web framework and a pile of libraries, and on top of those it carries smaller pieces, like a snippet from a forum answer or a helper an AI assistant wrote after seeing thousands like it. Software built from other software. Remixware is a name for that kind of software, and for a tool that keeps track of the parts.
