SlickFast

This is not a charting library. This is a deterministic render engine.

Spec in, same bytes out. Forever. It draws charts. It also draws Pages, like the one you're reading now.

Agents cannot draw. They can only write code. They force a browser to paint a picture, then take a screenshot they can't even verify. SlickFast doesn't use a browser. It renders: a JSON spec becomes an image — or a whole web document — and the output does not drift. Same spec, same bytes, forever.

Forty-seven types and tiled dashboards prove what it can draw. They are not the whole product.

Pages

A Page is a whole document from one spec: headline, words, charts, layout, at a public URL. You are reading one.

Paid Pages stay. Free Pages last 7 days and show a watermark. Local MCP draws on your machine for free, with no key. A public URL uses a key.

The twin

Every published Page has a twin: the exact recipe used to create it. You can see it at the same URL plus `.json`. This isn't an export; it's the source. The fingerprint at the bottom of the page is the mathematical proof that the page matches its recipe. If it matches, nothing changed. If it doesn’t, something did.

Don't trust us. Check the math. Add `.json` to this page's URL. That is how you verify.
