Cerbos vs Zed
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.
Zed is a Rust-built code editor by ex-Atom creators with instant startup, 120fps scrolling, real-time multiplayer editing, and built-in AI assistance — a faster alternative to VS Code.
About
Zed is a San Francisco-based code editor company building a high-performance, multiplayer code editor in Rust that aims to be significantly faster than Electron-based editors like VS Code while offering built-in real-time collaboration and AI assistance. Zed's Rust implementation enables near-instant startup, smooth scrolling at 120fps, and no performance degradation in large codebases where VS Code slows down. The editor's real-time collaboration feature allows multiple developers to edit the same file simultaneously with conflict-free synchronization — similar to Google Docs for code. Zed integrates AI assistance through a built-in language model interface that can explain code, generate completions, and refactor functions without switching to a separate tool. The company was founded by the creators of Atom (the open-source editor acquired by GitHub) and Tree-sitter (a parser generator). Zed raised over $26M from investors including Andreessen Horowitz and launched as an open-source project in 2024, driving rapid adoption among performance-conscious developers. It competes with VS Code, Neovim, and JetBrains IDEs.
