Extremely. I've been so pleased with Keepass and the security it provides. I'm using a web interface now (https://app.keeweb.info/) which is open source and worth checking out.
Keeweb is pretty awesome, and is amazingly just a static HTML page. If you're comfortable running your own secure webserver, you can self-host that for added security: https://github.com/keeweb/keeweb#self-hosting
