Design tooling has quietly converged over the past few years. Almost everything is now browser-first, collaborative by default, and priced per editor rather than per seat. That convergence is good news if you are choosing a stack, because it means switching costs are lower than they used to be and you can mix tools without breaking your workflow. The interesting differences are now in the details: how well a tool handles handoff to developers, whether it exports clean assets, and whether the free tier is genuinely usable or just a trial in disguise. The tools below span interface design, vector and raster editing, prototyping, and stock assets. If you are starting from scratch, pick one design tool and one asset source and stop there; collecting tools is a common way to avoid actually shipping anything.
