mkcert is a command‑line utility that creates locally trusted TLS certificates without any manual configuration. It automatically generates a local Certificate Authority, installs it in the system trust store, and issues certificates for any host names you specify.
Use cases
- Generate HTTPS certificates for localhost and custom development domains.
- Avoid browser security warnings while testing web applications locally.
- Create trusted certificates for Docker containers or local Kubernetes clusters.
- Provide TLS for local APIs, micro‑services, or mock servers during development.
- Set up secure connections for mobile app development on emulators or devices.
When to choose
- You need a quick, zero‑configuration way to obtain trusted certificates for development environments.
- You work across multiple OSes (Linux, macOS, Windows) and want a single tool that handles trust store installation automatically.
- Your workflow involves frequent creation of certificates for new hostnames or IP addresses.
When to avoid
- You are provisioning certificates for production services that require a public CA.
- You need advanced certificate management features such as revocation, OCSP, or automated renewal at scale.
- Your security policy forbids using locally generated CAs on shared machines.
