Epiq also solves this with a git-native backend, so it is vendor agnostic and adheres to a issue-tracking-as-code paradigm. It is therefore distributed, has a TUI + browser GUI, mcp server, and so on.

It is also event sourced, and supports state replay from beginning to end, so very powerful for auditing workflows, whether that be your own or a swarm of agents.
