The testing code is not open source yet, but we plan to make it available in the near future. We are also working on a code analysis tool, similar to Intel's IACA, that uses the instruction data from http://www.uops.info/. Finally, we also plan to add data for AMD processors.

Cool. Is is the IACA-alike tool:

?

It would be nice to see something with a more open and responsive development process compared to IACA.

No, this is a different IACA-like tool. Our tool is not public yet.

Oh cool, seems like we'll jump from zero to two direct competitors to IACA soon. I look forward to your tool (hopefully it can use the same IACA marker bytes so binaries and be compiled once for all these tools).

Yes, it will use the same marker bytes.

There is also llvm-mca, which is kinda neat since it uses the I formation that LLVM has about the op cost. Contrasting that to IACA or OACA is valuable as well.
