Ayrshare vs PostSider: Two Ways to Wire an Agent

I build PostSider, and Ayrshare has been around longer and serves a real, different job well. Check every number in this post against Ayrshare’s own pricing page yourself. Figures are current as of August 2026.

The short version: same underlying idea, two different buyers. Ayrshare sells API infrastructure to developers who are building the interface themselves. PostSider sells a finished product, dashboard included, that an agent can also drive. If you already know which of those two sentences describes your project, skip to the decision tree near the bottom.

Same problem, two different users

Both companies solve “give software the ability to post to social media.” The split is who is expected to use the result.

Ayrshare’s own positioning is explicit about this: it is core infrastructure for product builders, one integration covering the full social lifecycle (publishing, analytics, engagement, messaging, ads) that SaaS platforms, CMS and DAM tools, and agencies embed into their own product. You call the API, you build the screen your users see.

PostSider is the screen. The dashboard, the calendar, the approval workflow, all of it exists so a person can use the product directly, and the MCP server and REST API sit next to that as an equally first-class way in, not a replacement for it.

Where Ayrshare wins, stated plainly

Ayrshare has a real MCP server, hosted at api.ayrshare.com/mcp over Streamable HTTP, with 27 tools spanning publishing, validation, history, analytics, comments, messages, and profiles. That is more tool surface than PostSider’s 12, and Streamable HTTP means no local process to run, unlike PostSider’s stdio-only server today.

Ayrshare also built specific agent-facing features PostSider does not have: a History API that hands an agent a profile’s past posts so it can match voice from the first post, and pre-publish validation that blocks banned hashtags, duplicate content, and posting-limit breaches before a call ever reaches the platform. If you are building a product where many different end-user accounts each need their own history-aware, validated posting, that is real engineering PostSider has not shipped.

And at real scale, hundreds or thousands of profiles for a multi-tenant product, Ayrshare’s tiered per-profile pricing (down to $2.49 a profile past 500) can beat trying to fit that model into PostSider’s channel tiers, which were built for one team’s own accounts, not a platform reselling access to thousands of end users.

Where PostSider pulls ahead: a dashboard next to the agent, not instead of it

Ayrshare has no dashboard or calendar UI of its own. That is a deliberate choice for their buyer, and a real gap for a different one: a marketing team or agency that wants a person to see what the agent drafted, in a normal calendar, and click approve, without anyone writing a line of frontend code to build that screen first.

PostSider ships the human dashboard and the agent access as the same product. The same post an agent drafts through the MCP server’s create-post tool sits in the same calendar a human would use to write one by hand, goes through the same draft-review-approve workflow, and shows up in the same activity history either way. Nobody has to build a review screen. It already exists.

The other gap is platform breadth for a single team’s own accounts: PostSider covers 30+ networks including Bluesky, Mastodon, Reddit, Discord, and developer platforms like Dev.to and Hashnode. Ayrshare’s own materials describe 13+ networks. If your accounts live somewhere in that gap, it decides the comparison before pricing even comes up.

Pricing side by side

The units do not match, so read this as two different shopping lists, not one race.

	Ayrshare	PostSider
Entry tier	Premium, $149/mo, 1 profile	Standard, $20/mo, 5 channels
Mid tier	Launch, $299/mo, 10 profiles, webhooks	Team, $35/mo, 10 channels, unlimited team members
Scale tier	Business, $599/mo, 30 profiles, then $8.99 to $2.49 per additional profile	Pro $45/mo (30 channels), Ultimate $90/mo (100 channels)
Dashboard included	No, API and MCP only	Yes, plus the same MCP and API
Platforms	13+	30+
MCP server	Yes, hosted, 27 tools, Streamable HTTP	Yes, local process, 12 tools, stdio

If your unit of scale is end-user profiles inside a product you are building, run Ayrshare’s per-profile math against your projected user count; it is designed for exactly that and gets cheaper per profile as you grow. If your unit is your own team’s or your clients’ channel count, run PostSider’s flat tiers instead; a 10-channel team pays $35 flat on PostSider against $299 on Ayrshare’s closest matching tier, because that tier was priced for 10 end-user profiles inside someone else’s product, not for one team’s own accounts.

Decision tree: which one for which build

Building a product that resells social publishing to many end users, each with their own accounts, and you want to design your own UI: Ayrshare. That is precisely the job its pricing, its history API, and its validation layer were built for.

An unattended backend service that posts on a schedule with no human ever opening a dashboard, pure automation: either works technically, but check the per-profile math against PostSider’s flat tiers first if you are under maybe 15 to 20 profiles, since PostSider is cheaper at that range and still gives you the API if you never touch the dashboard.

A team or agency where a person needs to see and approve what an agent drafted, in a normal calendar, without building that screen yourselves: PostSider. The dashboard is not a bonus feature here, it is half of what you are buying.

Wide platform coverage beyond the mainstream 13, Bluesky, Mastodon, Discord, dev platforms: PostSider, since Ayrshare’s listed network count does not reach that far as of this writing [VERIFY: confirm Ayrshare’s current full platform list before publishing].

FAQ, migration, and using both

Some teams end up running both: Ayrshare inside a product they are shipping to end users, PostSider for the team’s own social accounts and the agency’s client work that needs a human approval step. That is not a strange combination, since the two tools are answering different questions.

Moving between them mainly means re-scheduling whatever is queued and reconnecting each platform’s OAuth on the new side; neither offers an automatic import of the other’s queue as of this writing [VERIFY: confirm current export or import support on both sides before telling a reader it works]. If you are coming from a REST-only setup and want the deeper mechanics of MCP versus a plain API, MCP vs REST vs SDK for social media covers that ground independent of either vendor.

The honest read: Ayrshare earned its position building for developers who want to build the interface themselves. PostSider exists because I wanted an agent and a human working the same queue without building that dashboard from scratch. Pick based on which one of those sentences is actually your project, and check the pricing page once you know.
