Quick verdict.
Choose Worklist if private task content and zero-knowledge encryption matter more than suite breadth. Choose Zenkit if its specialized workflow is the primary requirement. Zenkit is better when a team needs many project views, flexible data models, and suite-style collaboration. Worklist is better when task privacy is the core requirement.

Who should choose which?
Choose Worklist if...
- You handle sensitive client or internal project data
- You need strong encryption for regulated workflows
- You do not want server-side AI processing workspace content
- You prefer focused task management over a broad work OS
- You want the provider unable to read encrypted content
- You want a licensed self-hosted Docker option on your own hardware
Choose Zenkit if...
- You need kanban, Gantt, calendar, and chat-style collaboration
- Flexible project data models matter
- You want a broader suite instead of a focused task app
- Advanced administration matters more than content encryption
Security architecture.
Worklist: zero-knowledge.
Worklist encrypts all data on your device using ChaCha20-Poly1305 before it reaches our servers. We use OPAQUE PAKE for authentication so we never see your password. The encryption keys are derived from your password using Argon2id - we don't have them.
Result: Even if our database is breached, attackers get encrypted blobs. Even if served a warrant, we can only provide encrypted data we cannot decrypt.
Zenkit: conventional SaaS security.
Zenkit publishes standard security, privacy, or compliance information for cloud collaboration, but it does not position the product as Worklist-style client-side end-to-end encrypted task management. Zenkit is better when a team needs many project views, flexible data models, and suite-style collaboration. Worklist is better when task privacy is the core requirement.
Result: That means Zenkit can operate, index, support, or process workspace content in ways a zero-knowledge task app intentionally avoids. Use Worklist when provider-readable task content is the core risk.
Frequently asked questions.
Is Zenkit end-to-end encrypted?
No. Zenkit publishes encryption at rest and in transit, but not Worklist-style client-side end-to-end encryption. That means the service can process workspace content in plaintext for product features and authorized support workflows.
Can Zenkit employees see my data?
Zenkit publishes access controls and policies limiting employee access, but its architecture still permits authorized server-side access to workspace content. With Worklist's zero-knowledge architecture, even our engineers cannot access encrypted workspace content because we do not have the keys.
Can I use Zenkit or Worklist for HIPAA-regulated PHI?
Do not treat either product as HIPAA-ready by default. Worklist's zero-knowledge design may help with technical safeguards, but PHI requires a written compliance agreement or BAA with Worklist. Zenkit publishes GDPR and DPA information, but not a HIPAA or BAA program.
When should I choose Zenkit instead of Worklist?
Zenkit is better when a team needs many project views, flexible data models, and suite-style collaboration. Worklist is better when task privacy is the core requirement.
