OpenTweet
A posting service that lets you — or an AI agent — schedule and publish tweets, threads and cross-posts to X and Bluesky, without touching X's own paid developer API.

Description
If you've ever wanted to schedule a batch of tweets ahead of time, or let an AI assistant post updates on your behalf, you've probably hit the same wall: X (formerly Twitter) now charges real money and demands a developer account just to post through code. OpenTweet sits in between — you connect your account once, and after that you, or any AI tool you already use like Claude or ChatGPT, can schedule single tweets, full threads, and even identical posts on Bluesky, all from one dashboard or a simple API call, without ever dealing with X's paywalled developer program directly.
Technically, OpenTweet exposes 43 tools through both an MCP server and a REST API, covering posting, scheduling, threading (up to 25 tweets per thread), and analytics. It ships a drag-and-drop visual calendar, connectors for RSS feeds, GitHub and Stripe events, and webhook triggers, plus AI content generation across seven providers (Claude, GPT-4o, Gemini and others). Longer-form content can go out through X Articles, and DM campaigns run behind a human-approval gate so nothing goes out unsupervised. Client libraries exist for Python, Go, Ruby and PHP, and the service is also distributed as a Chrome extension and a Claude Desktop Extension.
💬 Our review
The short version: if you or your AI agent post to X regularly, OpenTweet removes the single biggest annoyance — X's own metered API pricing — for a flat monthly fee, and it does it without resorting to scraping or browser automation.
Against general schedulers like Buffer or Typefully, OpenTweet's edge is that it's built API-first for agents and developers, not just human social media managers: the MCP server and REST API are first-class citizens, not an afterthought bolted onto a UI. The $15.99/month entry tier is competitive once you account for X charging $0.20 per link-post directly, and the human-approval gate on DM campaigns is a sane safety default rather than a nice-to-have. The catch is the free tier is really just a 7-day trial — there's no permanent free plan — and everything depends on X's API staying available and priced the way it is today, which is not guaranteed. Worth it if you're automating posting from code or running an AI agent that needs to publish on X; skip it if you just want to schedule a handful of posts by hand, where a simpler tool like Typefully will feel less like overkill.
