About mkcert
mkcert creates a local certificate authority, installs it in the system trust store, and issues development certificates for any names you choose, such as localhost or custom test domains. Browsers and tools on the same machine then trust those certificates without warnings.
It needs no configuration and handles the trust stores on macOS, Windows and Linux, as well as NSS and Java stores. It suits web developers who need HTTPS locally without self-signed certificate errors.
Strengths
- No configuration needed
- Installs its local CA into system, NSS and Java trust stores
- Issues certificates for any hostname, including localhost
- Single Go binary
Limitations
- Meant for development only, not production certificates
- The local CA key must be kept private because it is trusted on your machine
