A workshop, not a product.

Cargo is a workshop. Every tool in it does one small thing and tries to do that one thing well. A playground for CSS effects. A library of text animations you can copy. A wrapper that frames a screenshot. None of them want to be a platform. They are the kind of tool you open once, take what you need, and close.

It is free and it stays free. Nothing to sign up for, nothing tracked, no ads now or later. If a tool helps you, take what it gives you and go build your thing. That is the whole transaction.

It gets built one Saturday at a time. Cargo is a side project and it moves at the speed of a side project. Some weekends a whole tool ships. Some weekends a single bug gets fixed and that is the weekend. The slowness is not a problem to solve, it is the point. Each tool gets to be properly finished before the next one starts, which is a luxury most software never gets.

Built on other people's work

Cargo does not stand on its own. The gradient tool is a port of Neat, an open-source gradient library by FireCMS. Two of its shaders, “Rainbow Warp” and “Ether”, come from Shadertoy, the second by an author who goes by nimitz. The text animation library follows a collection of a hundred animations published by 川合卓也 (Takuya Kawai) of KAWAI DESIGN, and many of the effects in it are older still, tracing back to Animate.css by Daniel Eden. The type is Manrope, Instrument Serif and IBM Plex Mono, all open-licensed. None of those people know this project exists. The work they shared openly made a good part of Cargo possible, and that is worth saying plainly.

One of those debts is currently unpayable, and it should be said out loud rather than buried: the author of “Rainbow Warp” is unknown. The Shadertoy link this project cited for years turned out to point at a different shader by a different person, so the credit has been withdrawn rather than left pointing at the wrong author. If you recognise the shader, please say so.

Every debt is written down, with whatever author, source and license is actually known, in the project's third-party notices. Cargo itself is MIT licensed. A few of the files it borrows are not, and that file says exactly which.
