AQVEN

AQVEN: Python framework and local Studio for building reliable LLM workflows with typed files and pre-run validation checks.

AQVEN is a Python framework and a local browser app Studio for building reliable LLM workflows with multi-step pipelines of models, tools, and human review. It keeps workflows as typed files in your repository, using flow files, markdown prompts, and declared types. The CLI command aqven check validates every connection and simulates flows offline before execution. Studio displays each run step by step, and the built-in Model Context Protocol server allows coding agents like Claude Code or Codex to manage project files. It supports inputs and outputs with strict typing, workflows composed of ten node kinds, and model providers through Pydantic AI.
