authentik vs SpiderOak

authentik is an open-source, self-hostable identity and access management product for workforce single sign-on, customer identity, zero-trust security, legacy application integration and API security. It supports OAuth2/OpenID Connect, SAML2, LDAP, RADIUS, SCIM and Kerberos, as well as WS-Federation. MFA options include TOTP, WebAuthn/passkeys, email, SMS, Duo and static tokens. Access policies can consider factors such as user attributes, time and location. Security features include audit logging, session binding, GeoIP and impossible-travel detection, and client certificate authentication with mTLS. It can run on customer infrastructure, including Docker and Kubernetes; the pricing FAQ says there is no hosted version currently. The authentik Agent integrates with Windows, macOS and Linux for local device login and CLI authentication. A free open-source plan includes community Discord support but no product support. Enterprise costs $5 a month, billed annually, at $5 per user per month; external users are $0.02 per month and service accounts have no cost.

SpiderOak provides access governance and secure data exchange for organizations handling critical data and services, including operations at the tactical edge. Its platform is aimed at developers and defense and commercial users in areas such as space, transportation, industrial systems, robotics, automation, and IoT. Access controls include role-based and attribute-based permissions, with the ability to revoke entities or roles. The platform runs as a serverless, asynchronous library on endpoints and works with any transport protocol. Command-line utilities and APIs support configuration, initialization, access control, data exchange, and transport integration. SpiderOak describes its architecture as decentralized and zero-trust, allowing connected endpoints to synchronize governance without centralized infrastructure. Commands are recorded in a distributed, synchronized, cryptographically authenticated, tamper-evident audit log. Separately, SpiderOakONE provides backup, sync, sharing, historical versions, and point-in-time recovery. Its listed plans include unlimited devices, with storage tiers from 150 GB to 5 TB. SpiderOakONE says it cannot read or reset a user's password and warns that losing it can make data unrecoverable. The commercial Team & Enterprise edition includes technical support; the Open Source Software edition does not.
