Bot liking recommendations please!

I am in need of a reliable web based bot for liking the posts of the followers of specific targeted accounts. No f/u or commenting or any other functions, liking posts ONLY. I own a mac and travel and do not wish to pay seperately for vpn service so I am interested in web based only, like Instagress. I want to run this for a single personal account. I have seen a few recommendations for services like Jarvee but $20/month is too much when i only need to use one function (liking) on one…

Bot liking recommendations please!
