barkdown
LiveA markdown to DOM round-trip codec, guaranteed to invert marked: canonical identity, fixed-point convergence, footnote fidelity, and no silent loss.
Packages & Tools
Software we built for production and published for everyone. These are the packages and tools that came out of real client and product work: extracted, hardened, documented, and released as open source.
Each one has its own page with the story, the install command, and the research or writing behind it. For the lighter side of what we ship, see Fun.

woof-editor
BetaA contenteditable markdown editor for Svelte 5, backed by barkdown's round-trip codec: WYSIWYG editing where the markdown you save is exactly the markdown you meant.
