This is a list of payloads that are constantly under maintenance.
Note - I did not create all of these payloads, rather I scour the internet looking for interesting polyglots and payloads. A lot of the credit goes to ismailtsdln, six2dez, hacktricks, payloadallthethings, and albinowax. If anything interests you feel free to reach out to me.
Feel free to fork as well!
