# Termius Termius is a cross-platform [[Secure Shell (SSH)]] client built around **synced credentials, team collaboration, and IDE-style ergonomics on top of the terminal**. Used by 2M+ engineers across macOS, Windows, Linux, iOS, and Android — proprietary, freemium with paid Pro and Team/Enterprise tiers. ## What It Replaces Plain OpenSSH + `~/.ssh/config` works, but breaks down across multiple machines, mobile devices, and teams. Termius is what you reach for when: - You manage 20+ hosts and need grouping, tagging, and search. - You want the same hosts on your laptop, phone, and tablet without rsyncing dotfiles. - A team needs to share host inventories without dropping private keys into Slack. - You want autocomplete and snippets in the terminal without scripting them yourself. ## Core Features | Feature | What it gives you | |---|---| | **Encrypted Vault** | End-to-end encrypted sync of hosts, keys, and credentials across all your devices. | | **IDE-style autocomplete** | Command completion for common CLIs inside the terminal pane. | | **SFTP** | Built-in file transfer with a graphical browser; no separate client needed. | | **Port forwarding** | Persistent local/remote/dynamic tunnels with one-click activation. | | **Snippets** | Saved command sequences runnable against one or many hosts. | | **Host grouping & tagging** | Organize by environment (Production, Staging, Dev), customer, or project. | | **Team Vault** | Share host inventories, snippets, and credentials with role-based access. | | **Workspace restoration** | Reopen the exact set of tabs and connections from your last session. | | **Activity logging** | Per-session command history (Team/Enterprise tier). | | **Mosh support** | Roaming-friendly SSH alternative for flaky connections. | ## Supported Platforms macOS · Windows · Linux · iOS · Android — true native apps on each, not Electron wrappers. The mobile clients are the differentiator: SSHing into prod from a phone is actually usable, with autocomplete and saved keys intact. ## Trade-offs to Know - **Proprietary, not open source.** The vault is end-to-end encrypted but the client is closed-source — you're trusting the binary. - **Cloud sync is the product.** Local-only usage works but you're paying for features that assume the sync layer. - **Free tier is intentionally limited** — sync, SFTP, snippets, port forwarding, and most team features sit behind Pro. Cost is per-seat per-month. ## Alternatives in the Space - **OpenSSH + dotfiles repo** — free, fully scriptable, no mobile story, no team sharing. - **iTerm2 / Alacritty / Ghostty / kitty** — terminal emulators, not SSH managers; orthogonal layer. - **WezTerm, Tabby** — terminals with SSH host management; closer competitors on desktop. - **Warp** — modern terminal with team features; AI-leaning, less SSH-management focused. - **Royal TSX, SecureCRT, MobaXterm** — older multi-protocol session managers, Windows/macOS-heavy. ## Use Cases I Care About - Mobile incident response — SSH to prod from a phone without retyping bastion configs. - Multi-customer consulting — one tagged vault per client, isolated and shareable with that client's team only. - Cross-machine continuity — same host list on the work laptop, personal desktop, and tablet without manually syncing `~/.ssh/config`. ## References - [Termius Website](https://termius.com) - [Termius Documentation](https://docs.termius.com/) - [Termius Pricing](https://termius.com/pricing) - [Termius Blog](https://blog.termius.com/) - [Termius Support / Help Center](https://support.termius.com/) - [Termius on GitHub](https://github.com/termius-corp) — primarily issue tracking and integrations, not the client source - [Termius Status Page](https://status.termius.com/) - [Termius Changelog / Releases](https://termius.com/blog/category/release-notes) ## Related - [[Secure Shell (SSH)]] — the underlying protocol - [[OpenSSH]] — the standard SSH implementation Termius wraps - [[Secure Copy Protocol (SCP)]] — sibling file-transfer protocol - Mosh — roaming SSH alternative Termius supports (no dedicated note yet) - SFTP — file transfer protocol bundled in (no dedicated note yet) - Secrets management — broader theme; vault is one slice (no dedicated note yet) - Developer environment — Termius as part of the cross-device dev setup (no dedicated note yet)
