Open source LastPass alternative
You're tired of paying $3/month for a password manager, but you don't trust the closed-source alternatives floating around—and honestly, you're right to be skeptical. The open source password manager space has exploded in the last 3 years, with over 40% of developers now actively evaluating self-hosted security tools.

Key insight: You're not competing against LastPass—you're competing against the psychological friction of self-hosting; most open source alternatives fail because they optimize for security theater instead of solving the 'why would my team actually use this over Bitwarden' problem.
Market Overview
There are roughly 15-20 legitimate open source password managers actively maintained, ranging from Bitwarden (the market leader with self-hosting capability) to smaller projects like KeePass, Vaultwarden, and pass. The common failure pattern is UX: most open source alternatives nail security but ship with clunky interfaces, poor mobile experiences, or zero ecosystem integration. The real gap isn't in the security layer—it's in making self-hosted credentials management feel as frictionless as LastPass, with seamless browser extensions, team collaboration features, and emergency access workflows that actually work. A new shipper should hyper-focus on the friction points LastPass users experience most: sync reliability, cross-device speed, and team onboarding friction. The market is growing because enterprises are finally auditing third-party password managers post-breach, and developers are willing to self-host if the friction drops below the convenience threshold.
