I didn't want my SSH hosts and credentials in someone's cloud, so I built an SSH manager that syncs device-to-device with no server

Hi, I'm Derek, and this is TerminalLynx. Every SSH manager I tried that syncs between machines wants an account and keeps my hosts and credentials on their servers. I didn't want that, so I built one that syncs directly between my own devices. What you see in the video: my desktop has 109 connections and my new laptop has none. I pair them with a one-time code and everything comes across. Then I add a server on the desktop and it shows up on the laptop a moment later.

AI 分析

痛点:注重隐私的开发者不愿把 SSH 主机清单和私钥交给第三方云同步,而主流 SSH 管理器(Termius 等)都强制注册账号并把凭据存在自家服务器上。

目标用户:同时使用多台电脑(台式机+笔记本)的后端/运维/SRE 工程师,以及有合规或隐私要求、不能把凭据放到外部云的小团队。

证据:Every SSH manager I tried that syncs between machines wants an account and keeps my hosts and credentials on their servers. I didn't want that, so I built one that syncs directly between my own devices. / Pricing: free for up to 25 connections on 3 devices. Pro is $69 once (with a year of updates) or $5/month. For comparison, Termius charges $10/month, mostly for cloud sync. Team sharing works the same peer-to-peer way, from $119/seat or $7/seat/month.

变现:买断制($69 一次性,包含一年更新)和 $5/月订阅并行;团队版按席位收费($7/seat/月 或 $119/seat 买断)。也可以先免费提供 CLI 版本获取用户,再靠 GUI 和团队共享功能收费。

MVP:2 周内先做最窄的版本:跨平台 CLI(例如 `tlx sync`),用 age 或 X25519 端到端加密,把 ~/.ssh/config 和 hosts 元数据打包成一个加密文件;私钥始终留在系统 keychain 中,不离开本机;通过 LAN mDNS 或让用户手填 Tailscale IP 完成配对,用一次性配对码完成密钥交换;不做 GUI,不做团队协作。

竞品:Termius、Royal TSX、SecureCRT、Warpgate、ssh config 同步类 VSCode 插件 / dotfiles 方案(chezmoi、Syncthing + git)

摘要:独立开发者 Derek 用 Rust + Tauri 做了 TerminalLynx:SSH 主机与凭据在设备间点对点加密同步,无需账号、不经云端,安装包约 5 MB。定价为免费版 25 个连接、3 台设备,Pro $69 买断或 $5/月,团队版 $7/seat/月;他直接对比 Termius $10/月 的云同步收费。发帖本身是产品发布,但反映出“本地优先、无账号”的开发者工具存在真实的付费替代空间。
