Can someone recommend a self-host alternative for n8n? I'd be fine paying for one of the lower tiers to get access to shared workspaces, so I can work with my small team, but if you want to self-host you have to jump up to the Enterprise version which can easily be 20x more expensive.

This makes it unusable for my purpose.

But in my (limited) research into options like Airflow or Dagster or Windmill, they weren't quite at the same level and it doesn't feel like a significant value-add over writing a simple webhook server.
