Weft AI Language

Skill by ara.so — Daily 2026 Skills collection.

Weft is a programming language (implemented in Rust) for AI systems where LLMs, humans, APIs, databases, and agents are base language primitives. You wire nodes together, the compiler type-checks every connection, and the program runs with durable execution backed by Restate (survives crashes, supports multi-day human-in-the-loop pauses). A visual graph view is generated automatically from code.

Installation & Setup

Prerequisites

• Docker (for PostgreSQL)
• Node.js
• macOS: brew install bash (Bash 4+ required)
• Rust, Restate, and pnpm are auto-installed by dev.sh
