Two takes on the same idea. A content library that refills itself, or a tag with a cooldown.

The real trade-off

RecurPost's whole pitch is recurring content that keeps itself full — and the RSS auto-refill is a genuinely useful feature Postonus does not have. If your evergreen strategy is "republish the blog automatically," that one capability might decide this comparison by itself.

What you give up going that route: RecurPost currently has no free plan, and multiple reviews mention it disconnecting accounts without notifying you, so a schedule can silently stop firing until someone checks the dashboard.

Recycling: library vs tag pool

Both approaches reuse the same saved post rather than reshaping it per platform — that distinction matters, because "recycling" and "repurposing" get used interchangeably in this category and they are not the same thing. RecurPost's libraries are a dedicated object you populate and manage; Postonus's tags attach to posts you already wrote, so a post tagged #tips can sit in more than one rule's pool without a copy existing anywhere. See evergreen recycling for how the cooldown works.

RSS auto-refill is the one piece of this that Postonus genuinely lacks. If a feed needs to become a stream of scheduled posts with no manual tagging step, that is RecurPost's job today, not ours.

Pricing at a glance

RecurPost's entry tier covers fewer accounts than Postonus's, and neither offers a free plan the way Postonus's free workspace does.

	Postonus Hobby	RecurPost Starter
Price	$12/mo ($115/yr)	$9/mo
Accounts	10	2
Daily post cap	No separate daily cap	10 posts/day
Free tier	Free workspace, no expiry	None — 14-day trial only

At the agency end, RecurPost's top tier adds 20 accounts, 3 users, client workspaces, and both internal and external approval in one bundle. Postonus's Business tier, at $99/mo, gives unlimited accounts and workspaces but assembles approval and client review from separate pieces — approvals plus revocable share links — rather than one named "agency" package.

Developer surfaces: MCP on both sides

RecurPost shipped a first-party MCP server, documented in their own knowledge base, and a public REST API. That rules out treating MCP access as a Postonus exclusive — it is not, here or against several other competitors. The difference worth naming: we found no CLI for RecurPost, while Postonus ships an npm CLI alongside its MCP server and REST API, all on the same plans.

When RecurPost is the better choice

Two concrete cases. First, if RSS-to-social automation is core to your workflow — turning a blog or news feed into a recurring content library without a manual tagging step. Second, if you run an agency and want internal-plus-external approval bundled with client workspaces in a single Agency-tier price, rather than assembling it from approvals and share links.

What Postonus does not do

• No RSS auto-refill. Recycling draws from posts you tagged, not a live feed.
• No dedicated content-library object. Tags on existing posts do the same job, with less structure than a purpose-built library.
• No live publishing on the free workspace. Drafts and content planning are free indefinitely; scheduling or publishing needs a paid plan.

Neither product is trying to be everything here. RecurPost leans into automation for people who publish the same kind of content on a loop — a blog, a newsletter, a podcast feed. Postonus leans into a wider platform list and a simpler mental model for recycling. Picking between them mostly comes down to whether your content already lives in a feed somewhere, or whether you are tagging posts by hand either way.
