Imagine a wiki that is just a single HTML file. One that you can deploy<br>anywhere: view locally, share in local network, put in any web server. No<br>databases, no user management, no moving pieces that cause headaches.

Feather Wiki is a<br>really cool project that I ran into a couple of weeks back. It’s a wiki<br>project that fits the entire wiki, including all the content, in a single HTML<br>file. You can upload it to a server (or use locally), make changes in browser<br>and when you’re done with changes, you download a new version of itself with<br>the changes and you can deploy that to update it.

Or like the project describes itself:

Feather Wiki is an HTML document containing a self-replicating JavaScript<br>application for creating wiki-style websites whose content is also stored in<br>the output.

You can edit the wiki in browser just like any other wiki but to permanently<br>save the changes, you need to download a new copy of the entire wiki with new<br>changes and upload that to your web server.

While this adds an extra step, I think the tradeoff is often a welcome one. To<br>enable collaboration, you can have people submit pull requests to a git<br>repository that gets deployed to a server.

I’m still experimenting with it myself and haven’t published any wikis built<br>with it yet but I think it’s a wonderful choice for individuals or small<br>communities that want an easy wiki solution.

Now available in Finnish!

Last weekend,<br>I contributed to the project by providing Finnish translations. You can download the Finnish version from<br>Downloads page. If any of the translations feels off or wrong, don’t hesitate to reach out<br>or<br>make a contribution directly to the project. Big thanks to existing translations of open source projects like WordPress<br>that I was able to use for inspiration and checking if my translations made<br>sense.

If something above resonated with you, let's start a discussion about it! Email me at juhamattisantala@gmail.com and share your thoughts . This year, I want to have more deeper discussions with people from around the world and I'd love if you'd be part of that.
