Hypefury was built for X and has never hidden its goal: growing an account. Automatic reposting of old posts, a link added as a comment when a post takes off, automatic replies, scheduled threads. Their pricing lists $6 a month for one channel and $19 for all channels, with a seven-day trial.
Kast starts at 29 € and aims for a different result.
Hypefury optimizes for follower count. Its automation features all serve that goal: reposting what worked, adding a link when a post passes a threshold, bringing back the best posts.
Kast optimizes for the number of sales conversations. The score before publishing keeps you from posting something that won't lead anywhere. Engagement capture turns reactions into a list of people, with their job title and company.
A creator who sells a newsletter or a course needs the first. A consultant who sells a five-figure engagement needs the second.

Everything to do with X: the growth mechanics, reposting, threads, the price. At $6 a month, it's the cheapest option in this comparison.
Automatic replies and DMs. On X, these features are tolerated. On LinkedIn, they put the account at risk, and it's your account.
Choose Hypefury if X is your main channel and your goal is audience.
Choose Kast if B2B LinkedIn is your main channel and your goal is booking meetings.
