Replay Software推出了全新SSH客户端Echo，专为iOS和iPadOS设计，支持现代终端工具和AI编程助手。这是该公司首款移动端应用，标志着其产品线从桌面扩展到移动平台。Echo针对近年来终端用户界面(TUI)的创新潮流进行了优化，提供快速现代的SSH连接体验。

文章总结

全新SSH客户端Echo正式发布

Replay软件工作室于2026年2月10日推出首款iOS/iPadOS应用——Echo，这是一款专为现代终端工具和AI编程助手设计的SSH客户端。

开发背景

近年来终端领域呈现两大趋势： 1. 基于Bubbletea等库开发的TUI工具（如lazygit）让终端界面更具交互性 2. AI编程助手（如Claude Code）改变了开发者的工作方式，需要随时通过终端进行交互

团队基于自研的Ghostty终端引擎开发，确保在移动设备上实现桌面级性能。

产品亮点

原生体验 - 采用Metal加速渲染 - 集成iOS钥匙串管理SSH密钥 - 支持Face ID安全验证

设备优化 - iPhone：配备专用快捷工具栏和手势方向键 - iPad：完整支持硬件键盘、分屏浏览和Stage Manager

AI支持 特别适配AI编程助手工作流，可随时通过SSH连接远程tmux会话，处理代码变更和差异对比。

视觉设计

  • 预置精选终端主题
  • 延续Replay一贯的简约无干扰界面风格

定价信息

App Store一次性售价2.99美元，无订阅和内购项目。
