> Hi HN, > > I built this because I often work in coworking spaces or do screen sharing, and I've always had this fear of accidentally flashing my .env file with production secrets to the whole room (or recording). > > It’s a simple VS Code extension that opens .env files in a custom grid editor. It automatically masks any value longer than 6 characters so I can safely open the file to check keys without exposing the actual secrets. > > It runs 100% locally with zero dependencies (I know how sensitive these files are). It just reads the file, renders the grid, and saves it back as standard text. > > It's open source (MIT) and I'd love any feedback on the masking logic or other features that would make it safer to use. > > Marketplace: https://marketplace.visualstudio.com/items?itemName=xinbenlv...
