I am pleased to announce the MVP release of WEISS - a fully web-based, no-code, drag and drop editor and manager for EPICS OPIs. 
A production demo version is publicly available here: https://demo.weiss-controls.org. Try it out!

Some of next features planned: 
- Login with Github/Gitlab via OAuth. Import and edit OPI files natively according to repository access, full standard version control compatibility with version checkouts;
- OPI groups: create logical groups of OPIs and their respective production git tags, and assign users that should have access to the group.
- Roles: Admin (full control, sets user roles, allocate users to OPI groups), Engineer (create/edit/update OPIs, push updates, create OPI groups), User (runtime only, use OPIs within it's assigned groups);⁠
- ⁠Several more widgets;
- ⁠UX/UI improvements according to feedback;
The project roadmap and decisions are documented here.

I am looking for contributors, testers and bug reporters.
I read some very interesting ICALEPCS papers on new web-based technologies. If you are interested, have questions or ideas, don't hesitate to reach out.

Best Regards,

André Favoto
