Steffen Becker f6c906f9fa perf: the word lists travel as .txt, which the host compresses
GitHub Pages serves a .dic as text/x-c and leaves it uncompressed, while
text/plain goes out gzipped: the English list cost 552 KB over the wire
where 191 KB would do. Only the fetch path changes; the mount name the
checker sees stays <code>.dic. Measured first load 1.83 → 1.70 MB.

EdenText

Powerful word processor — just one URL away.
Free · Open Source · Private by Design

CI License: AGPL-3.0 Version Status: beta

▶ Open EdenText


EdenText is a web-based, powerful word processor for everything from quick notes to full-length books. No server, no account — processing runs locally and your documents never leave your computer. Just one URL away, or completely offline as a slim browser app — only ~1 MB1 .

Note

EdenText is young, in beta and actively developed — more features are on the way. It is tested — the full suite plus LibreOffice round-trip checks run on every commit — but expect occasional bugs, and keep backups of documents you care about. The browser copy also keeps the last three versions of the open document, and offers them if it ever fails to load one.
