1Password is published by AgileBits. This page compares only projects with an explicit relationship to it; shared categories alone never create an alternative claim.
Recommended order uses OpenAlternative organic alternatives v4 (version 4). Relationship confidence, category fit, logarithmic popularity, as-of maintenance and freshness, bounded anomaly quarantine, and known-data penalties. Payment is fixed at zero.
A hard constraint removes a Project only when its stored fact is known and conflicts. Unknown facts remain visible, are called out below, and never become a negative claim.
Lightweight password vault server for Bitwarden clients
Vaultwarden reimplements the Bitwarden server API in Rust so that it runs comfortably on a Raspberry Pi or a small VPS, while the official Bitwarden desktop, mobile, and browser clients connect to it unchanged.
Secret management for applications and infrastructure
Infisical stores application secrets, syncs them into the platforms that need them, and rotates the ones that support rotation. Environments and folders keep development and production credentials properly separated.
Groups appear only when at least two credible projects qualify.
