Devyan
Overview
Devyan is a source-available experimental coding workflow with architect, programmer, tester and reviewer roles built with CrewAI and LangChain.
Best For Professions:
Devyan is an experimental Python coding workflow built with CrewAI and LangChain. It divides a software request among architecture, implementation, test-generation and review roles.
The original theyashwanthsai/Devyan repository documents Python dependencies and OpenAI and Serper credentials. It was last pushed in July 2024, and no repository licence declaration is shown. Model/search usage and local computing have separate costs.
A tester role generates test-related work, but automatic code execution is still a TODO. Evaluate the code and licence before using or distributing an adapted workflow.
