What Tools and Projects Does Exa's Corner Link To?

Updated

Exa's Corner is the personal site of Exa, Java developers and Unix/BSD sysadmins who have run open source code and free online services full-time since 2009. The site's "digital garden" collects small, self-made tools and services that otherwise wouldn't be linked from anywhere. Below are the projects the site itself lists, grouped by what they do.

Small Web Toys and Generators

These are browser-based utilities you can open and use directly:

  • Colorspace toy — an interactive way to explore color spaces.
  • SCP-style laptop sticker generator — produces sticker designs in the SCP Foundation aesthetic.
  • Pie-chart SVGs — generates pie charts as SVG files.
  • Welon — a web-based clone of Suika Game, the fruit-merging puzzle game.

Hardware Reference Material

  • GPIO pinout diagrams for uncommon single-board computers (SBCs) the authors have used, plus Raspberry Pi pinout diagrams kept for reference. If you work with less common boards, these diagrams save you from hunting through scattered forum posts.

Hosted Services and Infrastructure

  • Server status page — powered by Uptime Kuma, showing the state of the services Exa runs.
  • A Drasl instance — Drasl is an alternative Minecraft authentication server; Exa hosts their own instance.

Minecraft Mods and Code

Exa is primarily known for Minecraft mods. The site links to their mod listings on Modrinth and CurseForge, and source code lives on Forgejo (with a mirror on Codeberg). The garden also includes technical write-ups such as migrating Git repos to SHA-256 and notes on JVM arguments.

Community and Discussion

Projects are discussed in a community bridged across Matrix and Discord. Exa also appears on Mastodon, PeerTube, GitHub, YouTube, Bluesky, and Tumblr, and lists email as reliable but not fast.

How to Use This List

If you want a quick tool, start with the generators and the Suika clone. If you run a home lab or work with SBCs, the pinout diagrams and the Uptime Kuma status page are the practical entries. For Minecraft server operators, the Drasl instance is the item worth checking. The site describes itself as a living document that changes as it's written, so expect the listing to grow rather than stay fixed.
