Eraser AI is freemium: there is a free tier you can work in and paid plans above it. It is one of 391 freemium tools in the catalog, all labelled the same way so you are never surprised by a paywall.
Eraser AI does 3 things the catalog singles out: Generates architecture/system diagrams directly from a text prompt; perpetual free plan (3 files, 3 ai diagrams, 7-day history); diagram-as-code editing plus github/notion/confluence/vs code integrations.
Canva Magic Studio is the closest free alternative: it sits in the same Presentations & Design sub-category and is free tier + paid plans. Excalidraw+, Framer AI and Gamma also start free. The full list is on the alternatives page.
