Lasso Host

Lasso Host turns a registered project into a stable local URL. It resolves *.lasso to loopback, starts supported projects on demand, and proxies HTTP, HTTPS, WebSocket, and HMR traffic.

Default URLs

http://my-project.lasso:6766
https://my-project.lasso:6767

HTTPS is recommended for microphone, WebRTC, and other browser APIs that require a secure context.

Certificates

On first start, Lasso generates a local certificate covering *.lasso, localhost, and loopback addresses. It uses mkcert when available and falls back to OpenSSL.

If your browser shows a certificate warning, install mkcert, restart the host, and open the HTTPS URL again.

Register a project

cd my-project
lasso init
# or
npx @lasso-ai/cli init
lasso daemon start
