RSS.app shows up in “RSS auto-posting” searches because it does two real things well: turning almost any website into an RSS feed, and pushing new items from a feed into chat tools. What it doesn’t do is post to the social networks most people mean when they say “auto-posting” — that’s a genuinely different product, and worth knowing before you sign up expecting one and getting the other.
RSS.app’s core product is a no-code RSS feed generator — point it at a website (even one without a native feed) and it produces one, pulling from sources like Twitter/X, Instagram, YouTube, TikTok, Reddit, Facebook, and Google News as inputs. Its “Bots” feature then pushes new feed items out — but only to Discord, Slack, Telegram, and Email, refreshed as fast as every 15 minutes on premium plans. Notice what’s not on that destination list: Facebook Pages, X/Twitter, LinkedIn, Pinterest, VK, Instagram, or any other social network you’d actually publish to.
PostRSS starts from the opposite end: you already have (or can easily generate) an RSS feed, and PostRSS posts its new items directly to actual social networks — Facebook Pages and Groups, X/Twitter, LinkedIn, Pinterest, VKontakte, Threads, Bluesky, Reddit, Telegram, Tumblr, Mastodon, and more — on a schedule you control. It doesn’t generate feeds from other sites, and it isn’t a chat-notification bot; it’s built specifically to get your content in front of your social audiences, automatically.
| RSS.app | PostRSS | |
|---|---|---|
| Core product | No-code RSS feed generator + chat-notification bots | RSS-to-social auto-poster |
| Posts to social networks? | No — social platforms are input sources only | Yes, that’s the entire product |
| Bot destinations | Discord, Slack, Telegram, Email | Facebook, X, LinkedIn, Pinterest, VK, Threads, Bluesky, Reddit, Telegram, Tumblr, Mastodon + |
| Refresh speed | Every 15 minutes on premium plans | Frequency you set per source, down to minutes |
| Starting price | Free plan, paid from ~$8.32/month | $5/month |
If your problem is “this website has no RSS feed and I need one, then I want to see updates in my team’s Discord or Slack,” RSS.app’s generator-plus-bots combo is built exactly for that. If your problem is “I already publish content and I need it to show up automatically on Facebook, X, LinkedIn, Pinterest, or another social network,” RSS.app’s Bots won’t get you there at all — that’s not a destination they support. PostRSS is built specifically for that second job.
No — RSS.app’s Bots feature only pushes to Discord, Slack, Telegram, and Email. Social networks appear in RSS.app as feed sources you can pull from, not as destinations you can post to.
Not in the sense most people search for — it’s primarily a tool for generating RSS feeds from websites and notifying chat channels, not for distributing content to social media audiences.
Generating a working RSS feed from a site that doesn’t have one, and getting instant chat notifications (Discord, Slack, Telegram) or email digests when that feed updates.
PostRSS focuses on taking an existing feed — yours or a source you follow — and posting its items to social networks automatically; it isn’t a feed-generation tool for sites that lack RSS entirely.
RSS.app and PostRSS solve adjacent but different problems: RSS.app turns websites into feeds and notifies chat tools when they update; PostRSS takes a feed and posts its content to social networks automatically. If “auto-posting” means Facebook, X, LinkedIn, Pinterest, or similar, RSS.app’s Bots simply don’t reach those destinations — PostRSS is built specifically for that job.
