Key Differences

Product Category

KeeWeb: KeeWeb is a password manager for storing and browsing credentials in KeePass-compatible database files.

Zitadel: Zitadel is identity/access management (IAM) infrastructure for building login and authentication into applications.

Confusing a password manager with an identity platform leads to picking the wrong tool for building a login system.

Pricing

KeeWeb: KeeWeb is completely free with no trials, demos, or limits.

Zitadel: Zitadel is free up to 100 daily active users, then $100/month for Pro (up to 25,000 DAU), with custom Enterprise pricing above that.

Zitadel's pricing scales with usage since it's a service that runs your application's authentication, unlike a static local tool.

Authentication Delivery

KeeWeb: KeeWeb does not provide authentication-as-a-service; it only stores stored KeePass entries locally or via file sync.

Zitadel: Zitadel provides hosted login pages, MFA, passwordless/passkey login, and social login via Google, Microsoft, and GitHub.

Only one of these tools can actually power the login flow for another application.

Compliance Certifications

KeeWeb: KeeWeb does not document any formal compliance certifications.

Zitadel: Zitadel is ISO 27001 certified, SOC2 Type II certified, and OpenID certified, with data residency options in the EU, US, Switzerland, and Australia.

Regulated businesses need documented compliance certifications before adopting an identity provider.

Multi-Tenancy and APIs

KeeWeb: KeeWeb has no API or multi-tenant features; it offers multi-file support and cloud sync via Dropbox, Google Drive, OneDrive, or WebDAV.

Zitadel: Zitadel provides multi-tenancy for extending applications to new organizations, plus gRPC and REST APIs for custom integrations.

Building a multi-customer SaaS product requires programmatic, multi-tenant identity infrastructure that a personal password manager doesn't offer.

  • Generous free tier for smaller projects and early-stage products

Cons

Use Cases

Choose KeeWeb: Individuals who want a free, open-source, KeePass-compatible password manager with no cost, no limits, and cross-platform desktop/web apps.
Choose Zitadel: Engineering teams building authentication into their own product who need hosted login pages, MFA/passkeys, RBAC, and multi-tenancy, with a free tier up to 100 daily active users.
Need both: A SaaS company might use Zitadel to power login and authentication for its own product while employees separately use KeeWeb to store internal or operational passwords that aren't managed through Zitadel's identity flows at all.

KeeWeb

  • KeePass users wanting a modern interface — Existing KeePass and KeePassXC users switch to KeeWeb for a more modern, browser-friendly interface while keeping the same database.
  • Self-hosted password management — Privacy-conscious self-hosters run KeeWeb on their own server for full control over their vault.
  • Browser-based access without installation — Users needing quick cross-device vault access use the web version without installing anything.

Zitadel

  • Customer authentication for SaaS applications — Adding secure login, multi-factor authentication, and passwordless options to a product without building identity infrastructure in-house.
  • B2B multi-tenant identity management — Managing separate organizations, projects, and permission structures for many business customers within one platform.
  • Regulated and enterprise identity infrastructure — Meeting compliance requirements such as GDPR, ISO 27001, and SOC 2 while controlling data residency through self-hosting or regional cloud options.
