PostEverywhere is a new breed of scheduler: built for AI agents first, with a REST API and a hosted MCP server on every plan from $9 a month. OneUp is the established all-rounder — 12 networks, recurring posts, an inbox, and plans that scale to 80 accounts. Both put API and MCP access on their cheapest plan, so this is a closer fight than most OneUp comparisons.
Quick verdict
If you run 20 or fewer accounts and want an AI agent to do your posting, PostEverywhere's $9–$39 flat plans are hard to beat — but once you pass 20 accounts, need Snapchat, or want evergreen recycling and a social inbox, OneUp is the only one of the two that keeps up.
- PostEverywhere caps at 20 accounts on its $39 Scale plan; OneUp's Business plan covers 80 accounts for $240 a month billed annually.
- At 5 accounts, OneUp Basic is $15 a month billed annually versus PostEverywhere's $19 Starter — but at 10 accounts PostEverywhere's $29 Growth undercuts OneUp's $40.
- PostEverywhere includes its REST API, hosted MCP server, and webhooks on every plan from $9 a month; OneUp includes its API and MCP server on every plan from $15 a month billed annually.
- PostEverywhere does not publish to Snapchat or Reddit; OneUp publishes to Snapchat across its 12 networks, but does not post to Reddit either.
What PostEverywhere offers
PostEverywhere calls itself "the agentic social media scheduler built for AI agents." Connect Claude, ChatGPT, or Cursor to its hosted MCP server and the agent can write, schedule, and publish for you — or drive the same account from your own code through the REST API. Its own blog says the MCP server exposes 45 tools for publishing, scheduling, queueing, and retries.
Pricing is four flat plans: Lite $9 a month for 2 accounts, Starter $19 for 5, Growth $29 for 10, and Scale $39 for 20, with 20% off annual billing. Every plan includes unlimited scheduled posts, the full API, the hosted MCP server, webhooks, and AI Studio. There is a 7-day free trial (card required) and no free plan. Seats are included per plan: 1 on Lite, 2 on Starter, 3 on Growth, 5 on Scale.
Its published list is Instagram, TikTok, LinkedIn, Facebook, X, YouTube, Threads, Pinterest, Bluesky, Telegram, Discord, WordPress, and Google Business Profile. GBP posting is live on every plan, so there is no GBP gap. The gaps are Snapchat and Reddit.
Pricing head-to-head
PostEverywhere is cheaper up to its 20-account ceiling; OneUp is the only option past it. Our pricing comparison puts both in a wider table.
PostEverywhere vs OneUp: the full comparison
Where PostEverywhere wins
The developer experience. PostEverywhere's API, MCP server, CLI, and signed webhooks come with every plan from $9, and its MCP surface is the deepest of the two — 45 tools for publishing, scheduling, queueing, and retries. If you are building an agent workflow or wiring posting into your own app, it is the more complete platform. Our guide to what an MCP server does for social media scheduling explains what to look for, and our MCP scheduler roundup ranks both tools.
Price under 20 accounts. At 10 accounts, $29 flat beats OneUp's $40; at 20, $39 beats OneUp's $84 Growth plan by more than half. For a small team with a fixed set of profiles, that is real money every month.
Telegram and WordPress. PostEverywhere publishes to Telegram channels and WordPress, two surfaces OneUp does not list. If either matters to you, PostEverywhere is the only choice.
Where OneUp wins
Scale. PostEverywhere's ceiling is 20 accounts. OneUp's Business plan covers 80 for $240 a month billed annually, with extra accounts at $1 each. Agencies and multi-brand teams simply outgrow PostEverywhere.
Snapchat. OneUp publishes to Snapchat; PostEverywhere does not. If Snapchat is in your mix, the comparison ends there — see our Snapchat scheduling tools roundup.
Evergreen posting. OneUp includes recurring posts on every plan, so your best content keeps circulating. PostEverywhere's pages describe a queue and unlimited scheduled posts, but no evergreen recycling library.
The inbox, approvals, and automation around the scheduler. OneUp's social inbox, approval workflows, DM automations on Instagram and Facebook, and social listening all come on every plan, including $15 Basic. PostEverywhere's pages describe none of those.
Track record. OneUp has 130,000+ users and years of operation behind it; PostEverywhere is newer, smaller, and still unproven at that scale.
Which should you choose?
Choose PostEverywhere if you run 20 or fewer accounts, you want an AI agent or your own code driving your posting, and your networks are covered — especially if Telegram or WordPress matter.
Choose OneUp if you manage more than 20 accounts, post to Snapchat, need evergreen posts that repeat automatically, or want the inbox, approvals, and DM automations in the same tool. At 5 accounts it is also cheaper on annual billing.
FAQ
Does PostEverywhere support Google Business Profile?
Yes. PostEverywhere lists Google Business Profile among its supported platforms, and its own pages say GBP posting is live on every plan, including the $9 Lite plan.
Does PostEverywhere support Snapchat?
No. Snapchat is not in PostEverywhere's published network list; OneUp does publish to Snapchat.
Which is cheaper at 10 accounts?
PostEverywhere. Its Growth plan is $29 a month for 10 accounts, while OneUp's Basic plan at 10 accounts costs $40 a month billed annually ($15 for 5 accounts plus $5 per extra account).
Can I drive both tools from Claude or ChatGPT?
Yes, both offer a hosted MCP server on every plan. PostEverywhere's surface is deeper — 45 tools for publishing, scheduling, queueing, and retries — while OneUp's covers scheduling and publishing alongside its inbox and automation.
The bottom line
PostEverywhere is a genuinely strong new rival, and the better tool for developers and small teams who want an AI agent to run their posting at a low flat price. OneUp is better once your account count, network list, or workflow outgrows it. If that sounds like you, try OneUp free for 7 days — every plan includes unlimited posts, recurring posts, the social inbox, and API plus MCP access.
