Side-by-side comparison of AI visibility scores, market position, and capabilities
Cerbos is an open-source authorization platform that externalizes and centralizes access control logic, eliminating authorization code scattered across application services.
About
Cerbos is an open-source authorization solution founded in 2021 that provides a centralized policy decision point for application access control, allowing engineering teams to define, manage, and test authorization logic independently of application code. The platform uses a human-readable YAML policy language to define roles, permissions, and conditions, and exposes a simple API that microservices query to determine whether a user can perform a given action on a given resource. Cerbos addresses the problem of authorization logic becoming complex and fragmented as applications grow, typically spread across database queries, middleware, and application code in ways that are hard to audit, test, or modify. The company raised $7.5M in seed funding and offers a SaaS managed platform called Cerbos Hub for teams that want hosted policy management and audit logging. Cerbos is used by engineering teams at technology companies building multi-tenant SaaS products where fine-grained permission models are required. The platform supports attribute-based access control (ABAC), role-based access control (RBAC), and relationship-based access control patterns, making it flexible enough for complex enterprise authorization requirements.
Liveblocks provides collaborative editing infrastructure APIs enabling developers to add real-time presence, multiplayer editing, and comments to any application.
About
Liveblocks is a collaborative infrastructure platform that provides APIs and pre-built components for adding real-time collaboration features — presence, multiplayer editing, comments, notifications, and version history — to any application. Building collaborative features like those in Figma, Notion, or Google Docs requires complex real-time synchronization infrastructure involving WebSockets, operational transforms or CRDTs, conflict resolution, and persistent storage. Liveblocks abstracts all of this complexity, allowing product teams to ship collaborative experiences in days rather than building the underlying infrastructure from scratch over months.
