vystak

Declarative, platform-agnostic orchestration for AI agents. Define once, deploy everywhere.

Vystak builds nothing. It wires everything. Define your agent in YAML or code, and Vystak generates native framework code, provisions infrastructure, and deploys — from a single command.

Install

npm install -g vystak

Quick Start

# Create an agent definition
vystak init

# Preview what will be generated
vystak plan

# Deploy
vystak apply

# Tear down
vystak destroy

Features

• Declarative — YAML or Python definitions, no boilerplate
• Framework-agnostic — generates native code for LangChain, Mastra, and more
• Platform-agnostic — deploys to Docker, Azure Container Apps, with more coming
• Multi-agent — agent-to-agent communication via A2A protocol
• OpenAI-compatible — every agent exposes /v1/chat/completions and /v1/responses
• Change detection — content-addressable hashing skips unchanged deploys
• Sessions & memory — built-in persistence with Postgres, SQLite, or Redis
