Focused software for how your team really works
18 Cores is a suite of fast, no-bloat software from 18cores, LLC — built custom, with minimal dependencies, and designed to adapt to your workflow instead of replacing it. We ship paid products like 18 Cores Tracker and free, open-source libraries like coremd.

- Multi-tenant workspaces with real roles

More products are joining the suite — this is where they'll live.
Open source, from the same team
Free, MIT-licensed building blocks we ship and depend on ourselves — the tools behind 18 Cores, released for everyone. We ship what we use and fix what we hit.
A zero-dependency, pure-ESM markdown library — a parser (Markdown → AST), renderer (AST → HTML), a DOM → Markdown serializer, and two editors (split-pane + WYSIWYG) over one shared pipeline. No build step, no framework.
- Zero dependencies, no build step
- Parser + renderer + serializer + two editors, one pipeline
- Targets a common CommonMark + GFM subset
- MIT-licensed — runs in production inside 18 Cores Tracker
