Caddy is a modern open-source web server and reverse proxy known for its simple configuration, built-in HTTPS encryption and strong security. It works as a central gateway for web applications, APIs and container services.
What sets Caddy apart:
Automatic HTTPS: certificate management via Let’s Encrypt built right in.
Simple configuration: human-readable syntax (Caddyfile) or JSON API.
Security: TLS by default, modern cipher suites, secure defaults.
Performance: written in Go, efficient and resource-friendly.
Extensibility: plugins and modules for authentication, caching, logging, header management and more.
This makes Caddy a modern, low-maintenance alternative to classic web servers such as Nginx or Apache, ideal for dynamic and containerized environments.
Our experience with Caddy in client projects
We use Caddy very intensively as the central reverse proxy and entry point for our entire infrastructure and all applications. All external requests pass through Caddy and are forwarded from there to the respective systems. Through production use in numerous projects, we know the system’s capabilities and quirks first-hand and know how to use it efficiently, securely and traceably.
Understanding the strengths and mastering the challenges
We have deep expertise in configuring and building Caddy setups, from simple reverse proxy scenarios to complex, highly available infrastructures. Caddy stands out for its integrated certificate management, automatic HTTPS configuration and high performance. Because we understand how Caddy works internally, we can not only configure it but also optimize it deliberately and analyze problems at a deeper level. Challenges often arise when integrating into container environments or managing many certificates, which we handle reliably with proven structures and automation.
Our contribution to stable Caddy environments
We use Caddy in production together with container systems such as Kubernetes and Docker Swarm and know how to integrate applications cleanly and route them correctly. We configure L4 proxies, connect certificate authorities (CAs) such as Cloudflare automatically, manage SSL certificates and ensure secure, traceable deployments. Our configurations are created as infrastructure as code, versioned and documented, so changes always remain reviewable and reproducible.
