I've been running Tulir's bridge [0] for a few months now and my Facebook account gets locked out every week or so (requiring unlocking and a new password).
EDIT: Looking at the code, they use Tulir's bridge as well. I'd be..cautious about claming production level support with it due to the afore mentioned logout issue. Which is a shame since all of Tulir's bridges are high quality.
The bridgebox repo appears to be a bunch of bridges in docker containers. I wonder if it's really worth running the bridgebox and not a homeserver, versus using matrix-docker-ansible-deploy [1]. You already need the VPS space.
