HTTPS and Trust

DevProxy uses Caddy's internal CA to provide trusted HTTPS for local domains.

What Caddy does

Caddy generates certificates for https://<name>.local using its local root CA. Browsers trust those certificates only after the root CA is installed in the operating system trust store.

When trust happens automatically

If devproxy init or devproxy add runs on Windows, DevProxy can prompt for UAC and trust the local CA automatically when the certificate has not yet been generated.

When you need to trust manually

Run:

devproxy trust

or:

caddy trust

if the browser still warns about the certificate.
