Feather Wiki

Feather Wiki provides a self‑contained, browser‑based environment for building personal, non‑linear notebooks, databases, and wikis. All data and functionality reside in a single HTML file, eliminating the need for a server or external services, and the entire application loads in roughly 58 KB, enabling instant access and fast interaction.

The tool supports Markdown syntax, automatic saving, full‑size image rendering, and a range of extensions such as page transclusion, HTML‑to‑Markdown conversion, and a searchable index. Users can navigate via a simple menu, toggle a table of contents, and employ a SunEditor replacement for richer editing. Import and export features allow cloning pages and moving content between wikis.

Feather Wiki is open‑source under the AGPL‑3.0 license, free to host, and does not require a subscription. Its lightweight design and extensible architecture make it suitable for individuals who need a portable, offline‑first personal knowledge base without the overhead of larger wiki platforms.
