Spaces vs Later
Later is a visual social media planner and scheduler: a content calendar, publishing to eight networks, link in bio, analytics, AI caption credits and — from its Growth plan — a social inbox for Instagram and Facebook DMs. Spaces is messaging infrastructure for AI agents: one REST API and one MCP server that let the agent you already use — in Claude, Grok, ChatGPT, Cursor or your own code — read and answer conversations on Instagram, WhatsApp, LinkedIn and Messenger.
In one line: Later plans and schedules posts for people; Spaces is the connection your own agent uses to answer chats. Here is how they differ, and when each is the better choice. If what you need is a scheduler, Later's yearly price is lower than Spaces'.
| Spaces | Later | |
|---|---|---|
| What it is | Messaging API + MCP server for AI agents | Visual social media planner, scheduler and analytics |
| Built for | Developers and businesses whose own agent answers customers on chat apps | Brands, marketers and creators planning visual content |
| Channels | Instagram, WhatsApp, LinkedIn and Messenger (inbox). TikTok posts and comments are live — no TikTok DM inbox. Facebook Pages coming soon. | Publishing to Instagram, Facebook, TikTok, Threads, YouTube, Pinterest, LinkedIn and Snapchat. Inbox (Growth and up): DMs on Instagram and Facebook only; comments on Instagram, Facebook and TikTok. |
| The number you already use, linked by QR code, and it keeps working on your phone. No Meta approval, no templates and no Meta message fees. | Not listed. | |
| LinkedIn messages | Yes — LinkedIn profiles connect, and your agent reads and answers their messages | Publishing only; LinkedIn is not in the inbox |
| AI | No built-in agent: bring your own. Routines for new messages, keywords and no-reply follow-ups. | Caption Writer and Ideas on AI credits: 5 a month on Starter, 50 on Growth, 100 on Scale |
| API and MCP | REST API and https://api.spacesos.com/mcp on every plan, including Free | No API or MCP for Later's scheduling product on the pages we checked. The only Later API docs we found are a read-only Reporting API for its influencer product. |
| Price | Free: $0, 1 account, 50 actions a day, no card. Pay as you go: $9 per connected account a month, with 1,000 actions a month per account (pooled), then $5 per 1,000 (less at high volume). Reading messages is always free. No seats, no yearly option. | Starter $25 a month, or $18.75 billed yearly (no inbox). Growth $50 a month, or $37.50 billed yearly (2 social sets, 2 users, social inbox). Taxes extra. 14-day free trial. |
| Small brand, inbox included — monthly | $45 a month (5 × $9, 5,000 actions pooled) | $50 a month on Growth |
| Same, billed yearly | $45 a month — Spaces has no yearly option | $37.50 a month on Growth — cheaper than Spaces |
Example assumes a brand whose customers write in on Instagram, Messenger, WhatsApp and LinkedIn: on Spaces, five connected accounts within the included actions; on Later, Growth, the lowest plan with the inbox — which answers only the Instagram and Facebook ones. Billed yearly, Later Growth costs less than Spaces. This is not a like-for-like price. Later's buys a content calendar, publishing to eight networks, analytics and a two-network DM inbox for people. Spaces' buys chat accounts your agent works, including WhatsApp and LinkedIn, and does not include what your AI model costs to run.

- You want limits, pacing, warm-up and approvals handled for every account.
About how WhatsApp connects
Later does not list WhatsApp on the pages we checked, so this only matters if your agent needs WhatsApp.
Spaces links the WhatsApp number you already use by QR code, without the Business API. 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. That number stays under WhatsApp's own automation rules: Spaces keeps every account inside limits, which lowers the risk without removing it.
