Count editors, not people
Every tool here separates people who create from people who only look. Figma, Framer and Sketch all let unlimited viewers comment for free while charging for editor seats; Canva charges per team member on paid plans. Before comparing sticker prices, count how many people genuinely need to edit — in most teams it is a third of who you would guess, and that ratio decides the cheapest option.
The handoff is the product
For interface work, the file is not the deliverable — the specs, tokens and assets an engineer pulls out of it are. Figma's inspect and code-generation features are the reason it won the category, and any alternative needs a credible answer to "how does this become code". If your designs are marketing assets rather than interfaces, this consideration disappears and the calculus flips toward Canva or Adobe Express.
Non-designers need guardrails, not power
The most common failure we see is buying a professional design tool for a marketing team and getting an unused license plus off-brand output. Template-driven tools with locked brand kits produce better results from non-designers than a blank professional canvas ever will. Match the tool to who is holding the mouse.
Check what happens to your files if you stop paying
Read the downgrade terms before committing a design system. Policies differ on whether files become read-only, how many projects a free tier retains, and what export formats survive. This is cheap to check now and expensive to discover later.
