About Zero

What the tool does and who it's for

Zero is Vercel's experimental programming language built from the ground up for AI agents. Instead of editing source text directly, agents query and patch a semantic program graph while the compiler continuously validates every change. Humans request desired outcomes in natural language and review human-readable .0 text projections when necessary. Built specifically for agentic workflows, Zero features token-efficient graph manipulation, fast builds, low memory overhead, and zero dependencies.

Key capabilities

Semantic Program Graph: Programs are stored as graph databases of declarations, types, calls, and blocks rather than raw text files.
Graph Patching API: AI agents query, edit, and patch code using structured graph commands like zero query and zero patch.
Bidirectional .0 Projections: Generates readable source code views for human review with support for zero export, zero import, and zero verify-projection.
Immediate Compiler Verification: The compiler checks graph patches in real-time to reject invalid edits immediately.
Explicit Capabilities System: Avoids ambient global runtime access by passing system access through explicit parameters like world: World.
Token-Efficient Workflow: Minimizes LLM context consumption by allowing agents to inspect and update targeted graph nodes directly.
Multi-Profile Optimizations: Supports debug, fast, small, and tiny build profiles with detailed size and memory reports.
Native Cross-Compilation: Built-in target support for macOS, Linux (including musl), and Windows ARM64/x64 platforms.
