This is not true. Please read Zuul's documentation at  (or the
modernization proposal I'll be sending later today) for a short overview.

This is not true.
- OpenStack uses Nodepool for node management (VM teardown & bringing up
new nodes, and image building), not Jenkins.
- The reason why OpenStack uses Jenkins *with* Zuul rather than just Zuul +
Turbo-Hipster is purely due to inertia and less work required due to their
- OpenStack's use of Jenkins is limited to acting as a conduit for
- Zuul knows how many resources are online at any time, so Nodepool can be
(and is) used with it just fine.

So does Zuul; the OpenStack project is building release tarballs and have
nightly QA processes on stable branches, all with Zuul.

Fair enough, but then the argument of a "fully integrated solution" should
not be advertised as Phabricator's advantage, IMHO.
