Hey, these are some of the methods I figured and used when I just started playing and botting on OSRS a few months ago and a list like this would have saved me a lot of trouble! these methods aren't saturated (as of yet) and I hope you guys can take advantage of some of them before they become popular
buy small fishing nets from port sarim’s fishing shop and deposit it through the port sarim deposit drop box
Use: Precise’s Store Buyer
free script
5gp per small fishing net
360 fishing nets/hr
rough 80k gp/hr
telekinetic grab nature runes (BETTER THAN ZAMORAK WINE)
use telekinetic grab on two stacks of nature runes in the wilderness
you can be killed and it is recommended to watch your bot run
Use: make ur own script or beg a scripter to make a free one
2 stacks of nature runes (3 and 4)
roughly 1.2k profit per world hop
depending on how good fast your script is 150k-200k/hr

location of the nat runes ^
buying death runes from rune shops in varrock or port sarim
death runes go from 180gp-225gp in the rune shops and the grand exchange buys for more
Use: Precise’s Store Buyer
profit/hr: anywhere between 75k-100k depending on when it’s busy or not
other f2p methods that are well known:
tanning in al kharid
drinking jugs of wine -> filling up jug with water
smelting steel bars
other items that are profitable with Precise's store buyer
Needle and Thread (al kharid + rimmington)
general store (hammer, bowl, jug, etc.)
steel arrows (varrock + rimmington)
