@manualdousuario@cassidy I used buffer for LAS and I did not enjoy the experience. Let's just say that it had some bugs and also only (withotu advertising) allowed 3 days of posting and sometimes it wasn't reliable.
@manualdousuario@cassidy@jsparber turned me on to postiz (https://postiz.com) which looks good for a personal social media manager. If you self host it is free (so far). I got it working for bluesky and mastodon.
The big problem with it is that it is really centered around AI workflow. :P
You might find @mixpost interesting as an organization. It's a one time cost for 1 year of updates, and you can choose after that to renew or not. It's also "open core". The free version isn't very interesting but does let you use multiple mastodon accounts unlike postiz. It also has a better process for teams to have editorial process.
