I have published a web app on GitHub that I have been working on recently to make the process of making scripts when creating proof of concepts on pentests a bit less tedious / not require as much digging through past scripts etc.
There is currently not a huge variety of recipes available, but I am hoping to add more in the near future and hopefully will receive some ideas from the community or pull requests to add some more in.
A live version of the app can be found at: https://rastating.github.io/xss-chef/
A demo can be found here: https://twitter.com/iamrastating/status/1090758690519564288
And finally, the source code can be found at: https://github.com/rastating/xss-chef
Hopefully it is of use to people / someone / anyone :)
