KeePassXC is a free, open-source password manager you install on your computer, no cloud subscription required. It stores all your passwords, usernames, website addresses, secure notes, and file attachments in an encrypted file that lives on your own device (or in cloud storage of your choice, like Dropbox or iCloud). Nothing gets sent to a company's servers by default, which is what makes it appealing to people who want full control over their sensitive data. It runs on Windows, macOS, and Linux, and includes browser extensions so it can automatically fill in your passwords on websites in Chrome, Firefox, Edge, and others. Beyond basic password storage, it includes a password generator to create strong random passwords, two-factor authentication code storage (so you can keep those one-time codes alongside your passwords), and even hardware security key support for extra protection. The project is a community-maintained modernization of the older KeePass software, updated with a cleaner interface and more features while keeping compatibility with the same file format. It's completely free with no premium tier, the whole thing is open-source and community-driven. For founders, vibe coders, or anyone managing lots of logins for tools and services: this is a solid self-hosted alternative to paid password managers like 1Password or LastPass. You own your data, there's no monthly fee, and it imports from those services if you're switching. With nearly 27,000 stars on GitHub, it's widely trusted by privacy-conscious users worldwide.
