Network Lab Automation products/services?

Hello /r/networking

So I test router/switch hardware/software for my day job. Part of that job is building out topologies to test devices for different use cases.

The tedium comes with rebuilding cfgs, cabling and troubleshooting. I've been looking into some lab automation services/products and found a few online.

Just wondering if there's any other products out there? What's your experiences been like with these platforms?
