PostEverywhere beats us on three things, and they are not small
It is cheaper at entry ($9 versus $11.99), it covers 11 platforms versus one, and its published API ceiling of 10,000 requests a day is available on every plan while OpenTweet only reaches that on the $29 Advanced tier. It also ships a CLI, which OpenTweet does not. If any of those decide it for you, take PostEverywhere. The rest of this page is about the cases where they do not.PostEverywhere vs OpenTweet, side by side

PostEverywhere takes four rows: platform coverage, entry price, API ceiling at entry price, and the CLI. OpenTweet takes five on X-specific depth. Five rows are ties. Where a capability is not publicly documented, it is marked as such rather than assumed.
The real question is not tool count
33 versus 36 sounds like a close race. It is not the useful comparison, because the two tool sets cover different surface areas.
33 tools, 11 platforms
- Create, schedule, and publish across every connected network
- Campaigns, bulk operations, webhooks, retries
- Roughly three tools per platform of shared surface area
- Exactly right when one post should land in eleven places
36 tools, one platform
- Threads up to 25 posts, batch schedule up to 50
- Evergreen queue: add, list, update, remove, read history, settings
- X Articles: create, update, publish, list, get, delete
- Best-time analysis, top posts, profile growth, content gaps, inspiration search
Neither of these is the X official MCP server
Both tools sit above X rather than being X. X shipped its own MCP server at api.x.com/mcp on June 30, 2026, and it can post. What it cannot do is schedule, and every call it makes bills your own X pay-per-use credits. That is the reason a third-party posting layer exists at all, whichever one you pick.Who each one is for
Pick PostEverywhere if
- Your agent publishes to many networks, not only X
- You want the cheapest plan that includes an API, MCP, and X
- You need 10,000 API requests a day without moving up a tier
- You want a CLI as well as an API
Pick OpenTweet if
- X is the platform that matters and you want depth there
- You want X Articles, evergreen recycling, and X DM campaigns
- You want AI content generation as a core feature, not a credit balance
- You want an MCP surface where every tool is about X
Frequently asked questions
What is the difference between OpenTweet and PostEverywhere?
PostEverywhere is a multi-platform publishing API. It covers 11 platforms including X on every plan, ships a REST API, an SDK, a CLI, and a hosted MCP server at mcp.posteverywhere.ai with 33 tools, and starts at $9 per month. OpenTweet covers one platform, X, with 36 X-specific MCP tools, X Articles, an evergreen queue, AI content generation, X analytics, and human-approved DM campaigns, at a flat $11.99 per month.
Is PostEverywhere cheaper than OpenTweet?
At the entry tier, yes. PostEverywhere Lite is $9 per month for 2 connected accounts, versus OpenTweet Pro at $11.99 per month for 1 X account. PostEverywhere also includes X, the API, and MCP on that $9 plan. If price per connected account is the deciding number and you do not need X-specific features, PostEverywhere wins that comparison outright.
Which has better API rate limits?
PostEverywhere publishes 60 requests per minute, 1,000 per hour, and 10,000 per day on every plan. OpenTweet Pro is 60 per minute and 1,000 per day, with Advanced at $29 raising that to 300 per minute and 10,000 per day. So PostEverywhere gives you a higher daily ceiling at a lower price. OpenTweet only matches it one plan up.
Which has more MCP tools?
OpenTweet has 36 and PostEverywhere has 33, but the counts are not comparable because the scopes differ. PostEverywhere's 33 tools cover posting, scheduling, campaigns, webhooks, and bulk operations across 11 platforms. OpenTweet's 36 all target X, which leaves room for evergreen queue management, X Articles, best-posting-time analysis, top-post reporting, and content-gap detection.
Do both support webhooks?
Yes, this is a tie. PostEverywhere shipped webhooks alongside campaigns and bulk operations in June 2026. OpenTweet exposes webhooks at /api/v1/webhooks. If you need to react to a publish result rather than poll for it, either tool will do that.
Do I need an X developer account with either tool?
No, neither one requires you to create an X developer app. Both hold the X connection on your behalf, so you avoid the X developer portal and the X pay-per-use billing that has charged $0.005 a read, $0.015 a post, and $0.20 for a post containing a link since February 2026.
Can both schedule posts?
Yes. PostEverywhere schedules through its API and MCP server across all 11 platforms. OpenTweet schedules single posts, threads up to 25 posts, batch schedules up to 50 at once, and runs an evergreen queue that recycles proven posts on a recurring basis. Scheduling is worth calling out because X's own official MCP server cannot schedule at all, so both tools beat it there.
Which should I choose?
Choose PostEverywhere if your agent needs to publish to Instagram, TikTok, LinkedIn, Facebook, YouTube, Threads, Pinterest, Bluesky, Discord, and Telegram as well as X, if you want the highest API ceiling for the least money, or if a CLI matters to you. Choose OpenTweet if X is the platform you care about and you want X Articles, evergreen recycling, DM campaigns, X analytics, and a tool surface built only for X.
