Introducing Mycorrhiza, a free self-hosted wiki engine, developed by @bouncepaw and the numerous contributors. It features file-based storage, history, a custom markup language, categories, among other features.

Common use-cases: digital gardens, personal websites, diaries, documentation, encyclopediæ. The project is like 3 years old, so it is probably stable enough.
