Casket

Appearance

Casket ​

Casket is a fork of mholt's Caddy web server v1. Its goal is to maintain Caddy's original goal of being a straight forward, simple to use web server rather than the direction of Caddy v2 which has a focus on microservices and programmatic configurability.

Casket will come with all the features you love about Caddy v1, while also adding our own touches for convenience and usability.

New in Casket ​

INFO

These docs have only recently been forked from the Caddy v1 docs, so the features marked below with ❓ are not yet documented, but will be in due course.

  • ❓ Provide multi-platform Docker images at ghcr.io/tmpim/casket
  • Allow use of multiple headers for loadbalancing policy in the proxy directive (#1)
  • Add tryfiles directive, similar to Caddy v2 (#15)
  • Add exclude option to the basicauth directive (52c171f)
  • Add servearchive option to the browse directive to download folders as archives (17c7b06)
  • Default browse template is laid out better on mobile (#24)
  • ❓ Automatic MIME type detection based on extension to the mime directive (67a1cb7..69ea3e2)

  • Environment variables everywhere placeholders are supported (1bedd5e)

Fixes/updates in Casket ​

The following fixes have been made in Casket since the last Caddy v1 build:

Is Casket actively maintained? ​

Yes! Casket is actively maintained by a group of open source volunteers from tmpim. It is considered to be stable software, so it does not see much active development, but we do fix bugs and add features when necessary. Pull requests are welcome for any bug fixes or feature-creep you may encounter along the way.

Why not Caddy v2? ​

Our concerns with forking Caddy were mostly around keeping us within the bounds of what was provided to us by Caddy v1, without having to teach a whole lot of people the new semantics of Caddy v2's configuration format and pulling in a load of unnecessary "cloud-native" features. There are a few big things that pushed us away:

  1. Caddy v2 seems focused, as mentioned, on being a "cloud-native" web server a-la Traefik and co. This is great for those in that space, but for a bunch of developers best described as "hackers" who run our own small infrastructure it is biting off far too much to chew.
  2. Somewhat a side effect of the above, but Caddy v2 has terrible defaults for the average user. Things like JSON logs, Admin API, are all on by default with difficult at best ways to opt-out of those features.
  3. The configuration language was completely replaced, providing completely different semantics more similar to NGINX than what made Caddy good before. It still has automatic certificate management, but that's about all of the previous magic that remains.

Known issues with Casket ​

Asides from any possible open issues on GitHub, there are two big fish to fry for true maintainability going forward, that you should be aware of if you are considering using Casket:

  • Certmagic is very out of date; we are at risk of using deprecation path ACME depending on what direction Let's Encrypt may go in the future. tmpim is mostly missing anyone with a motivation to tackle this, and we probably wouldn't recommend casket for production / enterprise reliability for this reason. It's still a great tool for personal use or scenarios where you're comfortable exploring a different web server in the future if the project gets too stale.
  • Any plugin ecosystem is missing, and you will lose any benefits of the public builds if you have use-cases that fall outside of ours without making an effort to merge those plugins upstream in casket-plugins (PRs definitely welcome there too!).
