you can give this a try https://docs.airbyte.io/integrations for integrations it is open source, it will save you some effort on integration and you would be able to provide wider range of sources out of the box.
you can try it on any of the cloud vm's (aws,gcp,linode,azure etc.) and than shut it down if you don't like. Or you can try it on your local machine with vm.
However you make a good point. When commercial version is released i will make sure that source code is available for audit by purchaser for additional fees.
How is this product different from gitprime/waydev/usehaystack etc.? Are you focussing on metrics of development lifecyle alone or do you incorporate production/operational data as well?
How are the tests added? is there a specific format? or they can only be added through portal? may be add demo video of how this is used. Also slack link is no longer active.
I want to add "portfolio cost" constraint can you add that in constraint? or is it already used internally? basically i want portfolio with minimum cost that would give me x amount of passive income.
you can also look for technical co-founder, may be join https://www.startupschool.org/ there are lot of technical folks looking for product co-founders and vice-versa.
