Building applications is your job. Authorizing users is ours.
Design, build, test, deploy
Leverage our Domain-Specific Language to define user journeys and configuration directly in your codebase — no more jumping to another system to manage authentication and authorization.


Future-proof your products
Effortlessly update workflows and rules to meet the latest privacy regulations, security needs, or customer requirements — powered by intelligent AI that adapts with minimal effort.
Unify user authentication and authorization
Simplify your development experience by unifying authentication and authorization, reducing costly maintenance and updates.


Reduce risk, improve security
Enhance security with AI-powered dynamic behaviour management, providing real-time auditing, anomaly detection, and swift response to potential threats.
Why does building the user layer feel so broken?
Limited customization
Current tools promise simplicity but box you into rigid flows that can't be adapted to your needs.
Growing complexity
Manual configuration
Managing change from development into production using web-based configuration is inefficient and error-prone.
No unified view
You can’t see in one place how authentication and authorization are specified, making auditing and compliance a nightmare.
Build with code, not compromises
Low Code Tools vs. Prefactor
Low-code system
Simple but inflexible. A quick fix today, a bottleneck tomorrow.
VS
Prefactor
A DSL crafted for developers to define authentication flows, policies, and permissions with precision and growth in mind.
Why a DSL?
Code is clarity
Prefactor’s DSL integrates directly into your workflow, giving you control over your app’s logic.
Test what you build
Preview and stage every update before it goes live.
Version everything
Track changes, rollback with ease, and maintain a full audit trail.
The result?
You build smarter, faster, and without compromise
Delivering precision, transparency, and control
Choose a platform which authenticates, authorizes and audits your users with the flexibility of writing code yourself but with the benefits of a hosted platform
