About Mask
Mask solves a specific problem that comes up daily for anyone dealing with developer and design work: doing it once, fast, without an account. The goal was to keep the path from "open the page" to "get the result" as short as possible. No mandatory account, no cookie wall, no upsell at every step. It pairs naturally with the other developer utilities here when you need to chain a quick workflow.
