About Numblr
Numblr is an open-source, self-hosted alternative frontend for Tumblr and other sources. It can display RSS and Atom feeds and content from Tumblr (via RSS), Twitter (via Nitter), Instagram (via Bibliogram), Mastodon (via RSS), AO3 (via scraping), and YouTube (via scraping and RSS). The project says it does not store personal data on the server, does not require cookies or JavaScript for use, and can optionally save subscriptions and settings in cookies.
The author describes it as very scrappy but usable and asks users to host their own. Known issues include Tumblr RSS feeds lagging behind content by up to an hour or more, missing images and videos in Tumblr feeds, and a Tumblr post view that is described as pretty broken. An in-memory cache is available, with an optional database cache.
