Deploy Your Own

You can deploy your own version of the OpenChat to Vercel with one click:

Running locally

You will need to use the environment variables defined in .env.example to run OpenChat. It's recommended you use Vercel Environment Variables for this, but a .env file is all that is necessary.

Note: You should not commit your .env file or it will expose secrets that will allow others to control access to your various OpenAI and authentication provider accounts.

1. Install Vercel CLI: npm i -g vercel
2. Link local instance with Vercel and GitHub accounts (creates .vercel directory): vercel link
3. Download your environment variables: vercel env pull

bun install
bun dev

Your app should now be running on localhost:3000.
