What it does
Tired of $10/user/month project tools holding your data hostage? MasterGantt is a Project management tool with a different approach: single 1 MB file. Open it in your browser. That's it. No cloud.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
