Both AuditKit and WorkOS provide audit logging for B2B SaaS applications. WorkOS bundles audit logs as part of its broader enterprise-readiness platform, while AuditKit is a dedicated audit trail solution that is open source, cryptographically immutable, and self-hostable. Here is how they compare feature by feature.

AuditKit uses hash chains and Merkle tree proofs to guarantee that audit logs cannot be tampered with. WorkOS does not offer cryptographic verification of log integrity.
AuditKit is fully open source. You can inspect the code, self-host on your own infrastructure, and avoid vendor lock-in. WorkOS audit logs are proprietary and cloud-only.
AuditKit starts at $39/mo for 100K events with transparent, usage-based pricing. WorkOS audit log pricing starts at $99+/mo and requires bundling with other WorkOS products.
AuditKit includes a drop-in log viewer component your customers can use directly in your app. WorkOS does not provide an embeddable audit log UI.
Collect evidence, organize controls, and deliver tamper-proof audit packages from $99/mo.
Best practices for implementing audit logs in multi-tenant B2B SaaS applications.
Both offer tamper-proof logging, but AuditKit is open source, self-hostable, and more affordable.
