Spaces vs Ayrshare: a social publishing API for products, or an agent inbox on existing chat accounts
Ayrshare is a social media API for products: publish, schedule and analyze posts across many networks, manage comments and reviews, and, through its Messaging API, send and receive DMs on Facebook Messenger, Instagram, X and WhatsApp (private beta). It bills per social profile and has an action MCP server.
Spaces is communication infrastructure for AI agents: one REST API and one MCP server that let the agent you already use answer customer conversations on the Instagram, WhatsApp, LinkedIn and Facebook Messenger accounts a business already has, inside each platform's limits.
The difference: Ayrshare's API and MCP are built to put social publishing into a product, with official DMs on some networks. Spaces' are built to run an agent inside existing chat accounts, including LinkedIn messages.

Billing units are not 1:1, so this table uses two examples. Ayrshare counts one customer, brand or location as one profile, however many networks it connects. Spaces counts each chat account. Prices are in USD and exclude tax. Sources: spacesos.com/pricing and ayrshare.com/pricing, checked 11 November 2026. On account fees, Spaces costs less in both examples: four chat accounts for one brand are $36 against Ayrshare Premium at $149 ($198 with messaging), and five independent inboxes are $45 against Ayrshare Launch at $299. Ayrshare's price covers publishing to 13 networks, which Spaces doesn't do. The two prices pay for different jobs.
Choose Ayrshare if
- You are embedding publishing, scheduling and analytics into your own product, with one profile per customer.
- You need posting to networks Spaces doesn't cover, such as YouTube, X, Pinterest, Reddit, Threads, Bluesky or Google Business Profile.
- You want official-API DMs on Instagram, Messenger or X inside a product.
- One brand publishing to many networks is your billing unit, and you need publishing more than chat.
- You need comment moderation across many networks or review replies.
Choose Spaces if
- You are building an AI agent that has to answer customers on Instagram, WhatsApp, LinkedIn or Messenger, including LinkedIn messages.
- You want to keep the WhatsApp number already on the phone, connected by QR code.
- You need follow-ups that stop as soon as someone replies, webhooks for every new message, and scheduled messages (follow-ups and webhooks on Pay as you go).
- You want account safety built in: daily limits, pacing, warm-up, pause, and human approval of replies.
- You run a handful of independent inboxes: 5 chat accounts are $45 a month on Spaces, against $299 on Ayrshare Launch.
Some teams use both: Ayrshare for publishing inside a product, Spaces for LinkedIn messages and the WhatsApp number already on the phone.
Where they differ
Publishing API vs agent inbox
Ayrshare is built so a product can give each customer a profile and publish, schedule and measure posts across many networks from one API. Spaces starts where customers ask things privately on accounts the business already has: a WhatsApp message, an Instagram DM, a LinkedIn reply, a Messenger thread.
LinkedIn and WhatsApp
Ayrshare's Messaging API covers Messenger, Instagram, X and WhatsApp (private beta), not LinkedIn. Its WhatsApp integration is Meta's official Cloud API, with free-form replies inside the 24-hour window and templates not currently exposed. Spaces includes LinkedIn messages, and connects an existing WhatsApp number by scanning a QR code.
Both have MCP, for different work
Ayrshare's Action MCP lets an agent publish and validate posts, fetch analytics, manage comments and, where the Messaging API allows it, read and send DMs. Spaces' MCP server (https://api.spacesos.com/mcp, plus one server per channel) is built around conversations: read the inbox, reply, schedule a message, and run routines. Your agent can set Spaces up itself: paste "Set up Spaces for me by following https://www.spacesos.com/agents" into your agent.
Limits that protect the account
Spaces' limits protect the social account itself: per-channel daily limits, pacing, and a four-week warm-up. For up to 24 hours after a WhatsApp account connects, reconnects, or is disconnected and connected again, Spaces does not start new chats or outreach. Replies in chats that already exist still go out. Other channels have no reply-only window: the warm-up limits apply from the first day, and replies to people who wrote in go out immediately. Keys can be read-only, and you can pause every send or require a person to approve replies. This lowers the risk of a platform restricting an account, but it can't remove it.
