Authorization that
scales with you
Stop building permissions from scratch. AuthzX gives you fine-grained, policy-based authorization as a service. Bring your own identity provider — we handle who can do what.
$ curl -X POST https://api.authzx.com/v1/authorize \
-H "Authorization: Bearer <token>" \
-d '{
"subject": { "id": "user_123" },
"resource": { "type": "document", "id": "doc_456" },
"action": "read"
}'
// Response
{ "allowed": true, "access_path": "role", "reason": "User has editor role" }Everything you need for production-grade authorization
A complete authorization platform so you can focus on building your product, not reinventing access control.
Policy Engine
Define authorization rules using a declarative policy language. Express complex logic like RBAC, ABAC, and ReBAC without writing application code.
Multi-Tenant by Design
Built for SaaS from day one. Isolate tenants, manage per-organization policies, and scale without worrying about data leakage between customers.
Real-Time Decisions
Low-latency authorization checks powered by in-memory policy evaluation and caching. No performance trade-off for fine-grained control.
Resource Management
Register and organize your resources, define resource types, and manage attributes. Model exactly what you're protecting with a flexible resource hierarchy.
Complete Audit Trail
Every authorization decision is logged with full context — who, what, when, and why. Built-in compliance reporting and real-time event streaming.
Role & Entity Management
Model your permission structure with roles, groups, and relationships. Supports RBAC, group-based access, and direct entity assignments.
API-First
Everything is accessible via REST APIs. Integrate authorization checks into any language or framework. Manage policies, resources, and entities programmatically.
Feature Flags
Control feature rollouts with the same policy engine. Enable features per user, tenant, or percentage — powered by real-time authorization checks.
Bring Your Own IdP
AuthzX handles authorization, not authentication. Use your existing identity provider — Okta, Auth0, Azure AD, or anything that issues JWTs.
Manage everything from the console
A powerful admin console to manage policies, resources, entities, and monitor authorization decisions in real time.

Three steps to secure your app
Get from zero to production-ready authorization in minutes, not months.
Define Your Policies
Write authorization rules using our policy editor or API. Support for RBAC, ABAC, and relationship-based access patterns out of the box.
# Allow editors to update documents
policy "document_editor" {
subject.role == "editor"
resource.type == "document"
action in ["read", "update"]
}Model Your Resources
Register your resources, define types, and set up entity relationships. AuthzX understands your permission hierarchy.
POST /v1/resources
{
"type": "document",
"id": "doc_456",
"attributes": {
"org_id": "org_123",
"classification": "internal"
}
}Check Permissions
A single API call to authorize any action. Sub-millisecond responses with full decision context for debugging and auditing.
POST /v1/authorize
{
"subject": { "id": "user_123" },
"resource": { "id": "doc_456" },
"action": "update"
