    Crystal Shards API Documentation Hosting

    This is a website I developed in Crystal for hosting API documentation for Crystal shards (aka gems, crates, libraries, etc). It's built in Crystal itself and is using Postgres, Kemal, the built-in doc generation tooling, and Lexbor. I've been working on this for a number of months and I'm proud of where it's gotten. All feedback welcome!


  • crystal-docker-quickstart

    A project template for quickly working with the Crystal programming language in a Docker container, no installation needed.

    Happy Crystal user and code contributor here. (Also created in case you want to try Crystal without installing anything.) In my opinion:

    - Slow compile times are still a pain for iteration.

    - The REPL / interpreter mode is still rough around the edges.

    As far as companies using Crystal:

    - We’re using it happily in production at Heii On-Call

    - Kagi is using it for their search engine backend

    - Other companies using it list:

  • InfluxDB

    Collect and Analyze Billions of Data Points in Real Time. Manage all types of time series data in a single, purpose-built database. Run at any scale in any environment in the cloud, on-premises, or at the edge.

    The Crystal Programming Language

    Yeah, there's a GH issue thread here that I keep an eye on:

    I figure whenever windows support lands will be a good time to give it a shot again.
