1. PinBoostr
Best free optionFree in beta · Every account
PinBoostr automates the half LinkedIn allows: it publishes posts you wrote and approved, through the official API, with one posting permission and no browser extension. You draft by hand or with AI trained on your own past posts, design carousel decks in a built-in studio, and drop everything into weekly posting-time slots. It also runs a full Pinterest engine from the same dashboard.
Best for: Creators, founders and small teams who want consistent posting without an extension touching their account.
