Sandkey

Sandkey is the credential manager built for developers, not end users. When you spin up a new local project — Laravel, Rails, Django, a Docker stack — you always end up typing the same default credentials over and over: admin / admin, root / secret, user@example.com / password. Sandkey remembers them for you and fills them in with one click. Local-first, always. Your credentials never leave your machine. There is no account, no server, no sync, no analytics. Everything is stored in Chrome's local storage and stays there. Sandkey cannot phone home because it has no home to phone. Open source. Sandkey is fully open source and available on GitHub: https://github.com/illegalstudio/sandkey Read the code, audit it, fork it, contribute to it. Built for sandbox domains. Sandkey is designed around the domains developers actually use: localhost, *.test, *.local, *.home.arpa, custom Docker hostnames. It supports wildcard patterns at any depth and port-aware matching — localhost:3000 can have different credentials than localhost:8080. Longest-match priority. Configure *.test as a catch-all and *.api.test for a specific project. Sandkey always picks the most specific rule — no surprises. Autofill that works everywhere. The autofill dropdown is injected via Shadow DOM, so it never clashes with the page's own styles. It works with React, Vue, Angular, and plain HTML forms — including dynamically rendered ones. No bloat. No background service worker. No remote calls. No dependencies. The entire extension is a handful of vanilla JavaScript files.
