I believe this might fit your use. https://onedev.io/ it’s open source as per here: https://github.com/theonedev/onedev When I worked for BioWare for ten years (EA for 13) we used a very awesome product called QuickBuild (Build system, Jenkins is trash. QB is based on Hudson) made by them, pmease. Robin Shine is the dev and he’s really cool, very responsive. Check it out, they make good stuff.

This is perfect if you’re going the kanban route, which is arguably sufficient. It’s nice that they have different deployments and a demo.
