I built RVault because I wanted a fully local password manager that lives in the terminal and whose internals I could actually understand.
It uses a CLI + TUI interface and focuses on keeping everything local without relying on browser extensions or hosted services.
I wrote a longer story about the design decisions and how it evolved here: https://medium.com/@atasesli05/one-user-one-problem-so-i-bui...
Happy to hear feedback or answer questions!
