Devlingo

This project is a diagramming and design product that supports AI usage. We developed it until an early alpha version and then decided to pivot due to lack of interest from investors.

You can see the landing page for an earlier version of the code in the repository here: https://devlingo.net

The code is open sourced with the hope it will bring people value. If anyone is interested in taking over this project and continuing development, please feel free to contact us by opening an issue in the repository.

Installation:

1. make sure to have pnpm installed globally (npm i -g pnpm)
2. run pnpm install -r

To lunch the dev environment, use docker - docker compose up. Make sure to have an up to date .env.development file in the root of your repository.

docker compose up db --detach

Then export the env variables for the DB connection:

And now execute the migration commands:

pnpm run prisma:migrate:dev

Followed by:
