And Open Source tool called TOTEM (Toolbox of Traffic Engineering Methods) exists. It has not been maintained since 2008 and was done as a university research project. You can do some things with it that you can do with the likes of Cariden and WANDL and it takes XML files. It is a bit of a pain to use, but can be extended. Another Open Source tool with similar issues and no GUI is CSPF simulator, which runs some algorithms and you can give it topology and demands and it can give you optimal LSP placement. Again, requires a learning curve and was actually Cisco side project a while ago. And finally, if you can program, you can take Python NetworkX library which provides SPF algorithm, which can be adopted for CSPF and you can look up some popular algorithms on the Internet and implement them. And then use some tool to create graphs. But in reality Cariden and WANDL are actually pretty vendor agnostic, and you can easily adapt them for anything. There are people who run Juniper networks and use Cariden and Cisco NSPs that use WANDL. And they are entering DC underlay world as well. They cost money, but you do get what you pay for.

You can look at tools like NS2/NS3 or OMNet++, but these are not going to do what you want out of the box, they are a framework for network simulation but you'll have to program them to do what you want, they are more used in academic settings.
If you want a nice interface you are kind of stuck right now with the commercial offerings from Cariden, OpNet, WANDL (now Juniper), and Aria Networks. Most of those packages are extensible via scripting if you want to do additional things.

I'm aware about the Cisco MATE software, but I'd prefer an open-source, vendor-agnostic one, something that in-house imporvements can also be achieved.

You can use Caridan tool, Cisco own it currently and it does all the computation needed and can draw your network topology
