Drift is a self-hostable Gist clone. It's also a major work-in-progress, but is (almost, no database yet) completely functional.
You can try a demo at https://drift.maxleiter.com. The demo is built on master but has no database, so files and accounts can be wiped at any time.
If you want to contribute, need support, or want to stay updated, you can join the IRC channel at #drift on irc.libera.chat or reach me on twitter. If you don't have an IRC client yet, you can use a webclient here.
Drit is a major work in progress. Below is a (rough) list of completed and envisioned features. If you want to help address any of them, please let me know regardless of your experience and I'll be happy to assist.
- creating and sharing private, public, unlisted posts
- syntax highlighting (detected by file extension)
- multiple files per post
- uploading files via drag-and-drop
- responsive UI
- user auth
- SSO via HTTP header (Issue: #11)
- downloading files (individually and entire posts)
- password protected posts
- sqlite database (should be very easy to set-up; the ORM is just currently set to memory for ease of development)
- non-node backend
- administrator account / settings
- docker-compose (PR: #13)
- publish docker builds
- user settings
- works enough with JavaScript disabled
- documentation
- customizable homepage, so the demo can exist as-is but other instances can be built from the same source. Environment variable for the file contents?
