Plexica — Multi-Tenant SaaS Platform

Why Plexica?

Enterprise-grade multi-tenancy without the complexity tax.

Schema-per-Tenant

Each tenant gets an isolated PostgreSQL schema. DROP SCHEMA for GDPR right to erasure. No shared data, no leaks.

Multi-Realm Auth

Every tenant gets its own Keycloak realm. SAML, OIDC, social login, MFA — configured per-tenant.

Plugin System

UI plugins via Module Federation, backend via HTTP proxy, event subscription via Kafka. Plugin in half a day.

RBAC + ABAC

Role-based access control with attribute-based condition tree for workspace-level data isolation.

Event-Driven

Kafka/Redpanda event bus for async plugin communication. CRUD events emitted automatically on core entities.

Zero-Mock Testing

E2E tests run against real Keycloak, real PostgreSQL, real Kafka. What you test is what runs in production.
