I built django-vtasks to replace Celery (task queue) in my open source project, GlitchTip. I wanted something with an asyncio-first approach that supports Valkey and Postgres backends. Sync tasks run in threads. We don't support every Celery broker and feature, but I think we have a good feature set and we outperform Celery in benchmarks. Being able to run my_task.aenqueue() is friendlier than doing this in Celery from an async view. It allows for a true asyncio valkey call, not sync_to_async. I found django-tasks not performant enough, as I need high concurrency. (As I understand, Django Tasks is modeled off of that project, so thank you to django-tasks folks). If this sounds useful, give it a try. Or better yet, submit a bug report or merge request.

We added experimental support for Postgres-only mode - no valkey/redis needed. We have an all-in-one script (also experimental) to embed celery and web as one process. Together, this gets the memory requirements quite low. It's a core goal of mine to ensure GlitchTip is as easy to host as possible. Report any issues. I'd love to know any feature requests related to self-hosting too.
