Came here to recommend exactly this!

Though the wonderful thing about plane specifically is you don't have to selfhost it. Its great without self hosting too.

I've done project management with small team and solo projects for around 5 years now and I've seen a lot go into the shitter... Plane is open-core, and I expect it'll be safe for a long while given the way other project management software has been going.

I've used Trello the most, but also lots of Jira and HackNPlan. Taiga (there are two, forget which is which off top of my head) was alright until it wasn't. I started REALLY looking after this, and landed on either Wekan or Plane. If you can selfhost and don't mind the limited featureset (possibly fine solo!) - wekan may be great. But plane is absolutely wonderful and what I use with my tiny team now.
