3 tools that schedule text, link and image posts to subreddits, with flair selection and subreddit rule checks where available.
Agency features (inbox, reviews, white-label reports) at a lower price than the usual suspects.
Open-source scheduler you can self-host, with a hosted plan if you would rather not.
Self-hosted scheduler built on Laravel, with a free Lite edition and a paid Pro licence for teams.
Reddit scheduling is a small niche, partly because subreddit rules differ and automated posting can look like spam. The tools that support it (Postiz, Mixpost, Vista Social) let you pick a subreddit and flair per post. Post at human hours, follow each community rules, and avoid identical cross-posts across many subreddits.
Postiz, Mixpost and Vista Social publish to Reddit. Most mainstream schedulers do not.
Vista Social and Postiz let you add several subreddits as separate destinations. Space posts out to avoid spam filters.
Posts are judged by subreddit rules and spam filters, not by how they were published. Low-karma accounts and repeated links are the usual triggers.
