HTTPS on localhost.
One checkbox.

Some features don't work without HTTPS. Secure cookies, service workers, WebAuthn, certain OAuth flows — they all demand a secure context. In production, your cloud provider handles it. In development, you're on your own.

Donk generates a local Certificate Authority, installs it in the Windows trust store, and issues certificates for any domain you configure. Check the "Enable SSL" box. Your server is now available on https://myapp.test with a green padlock. The certificate is trusted — no browser warnings, no "proceed anyway" clicks.

• One checkbox to enable HTTPS — no config files, no CLI commands
• Custom .test domains — myapp.test, api.myapp.test, anything
• Auto-generated local CA installed in the Windows trust store
• Green padlock in every browser — Chrome, Firefox, Edge all trust it
• Wildcard certificates for subdomain routing — *.myapp.test
• Caddy reverse proxy handles the HTTPS termination — your app sees plain HTTP
• Works across LAN — your phone trusts it too after one CA install
