CoScreen创始人Jason Thomas宣布推出Petal，一款免费开源的屏幕共享和配对编程工具1。该项目由CoScreen原团队的四名成员——Jason Thomas、Till、Max和Darren——在不到八周内完成开发1。
Petal的诞生背景源于行业现状的转变。Datadog于2025年7月31日关闭了CoScreen服务1，而CoScreen原本耗时近六年开发，在2022年被Datadog收购1。新工具旨在打破屏幕共享解决方案被大公司收购后随之关闭的循环1。
在功能方面，Petal支持多人共享窗口、实时光标标记以及跨平台使用1。目前该工具已在macOS和Windows上可用，Linux版本正在开发中1。开发团队采用了Fable和Astra等前沿模型加速项目进展1。在基础设施上，Petal使用LiveKit处理媒体传输，用户可选择自托管或采用第三方视频后端1。项目承诺完全免费且不进行商业化1。
Jason Thomas, founder of CoScreen, has announced the release of Petal, a free and open-source screen sharing and pair programming tool 1. The project was developed by four members of the original CoScreen team—Jason Thomas, Till, Max, and Darren—in the two months following Datadog's decision to shut down CoScreen on July 31, 2025 1. The rapid development cycle, completed in under eight weeks, was made possible through the use of cutting-edge AI models including Fable and Astra 1.
Petal is designed to break the cycle of screen sharing tools being acquired by major corporations and subsequently discontinued 1. The tool supports multiple users sharing windows simultaneously and includes real-time cursor indicators, with current availability on macOS and Windows platforms, while a Linux version is in development 1. The software is built on LiveKit for media transmission and offers users the flexibility to choose between self-hosting or third-party video backends 1. As a fully free and open-source project, Petal will not be commercialized 1.
This release comes after CoScreen's original six-year development period before being acquired by Datadog in 2022 1.
