Yeet is a free and open source tool that automatically cross-posts content between X and Threads. When a user writes a post on X, it is published on Threads without further action. Similarly, posts written on Threads appear on X. The tool supports both text and images, ensuring that the same content appears on both platforms simultaneously. Yeet is available as a browser extension for Chrome, Edge, and Firefox. The primary function of Yeet is to eliminate the need for manual copy-pasting between the two platforms. It operates as a two-way sync by default. Users can pause the posting process at any time, review the last cross-posted item, and continue posting while the other timeline fills automatically. An option to include images can be toggled on or off. The tool also tracks the number of double posts it has prevented, offering a basic counter of skipped duplicates. Typical use cases include managing a presence on both X and Threads without switching interfaces or duplicating effort. Users write a post in their usual composer on one platform, and Yeet handles the mirroring. This workflow is suited for individuals or organizations that want to maintain consistent messaging across both platforms with minimal overhead. The tool is designed to run silently in the background, requiring only that the user has both accounts connected. Technical requirements include having an account on both X and Threads and installing the Yeet browser extension. The project is open source, and its source code and further documentation are available through its website.
