The Termius alternative that owns the desktop.
Mongrel is a Termius alternative for engineers who live at a desk: SSH, Mosh, Telnet, Serial, and local terminals with logging, triggers, quick commands, and recording, plus a direct read-only import of your Termius session database. Termius remains the stronger product on mobile; Mongrel's answer is a deeper desktop terminal wrapped in a workbench of databases, Docker, Kubernetes, and SFTP.

// Why teams switch
Subscription SSH is fine. A terminal island is not.
Termius made SSH pretty and synced it everywhere, and its mobile apps are genuinely good. The friction starts when the terminal is only one stop on the debugging trail: you SSH in, then open a database client, then a file transfer tool, then a Kubernetes dashboard. Mongrel puts the terminal, the databases, the containers, and the files in one window, and it imports your Termius sessions so the switch costs an afternoon, not a week.
// What ships
What Mongrel adds around the terminal.
Full desktop terminal
SSH, Mosh, Telnet, Serial, and local shells with logging, regex triggers, quick commands, guarded broadcast, themes, search, and asciinema recording with a replay player.
Direct Termius import
A read-only scan of the Termius SQLite session database with schema-drift tolerance; passwords and keys are re-entered after import and stored in the OS keychain.
Tunnels and jump hosts
Jump-host chains, local and remote port forwarding, key and agent authentication, and per-connection database tunneling where supported.
30+ database engines
PostgreSQL, MySQL, SQLite, MongoDB, Redis, Oracle, SQL Server, ClickHouse, and more through built-in drivers and signed first-party plugins.
Docker and Kubernetes
Containers, images, pods, logs, exec, and port-forwarding next to the servers you already SSH into.
Dual-pane SFTP/SCP
Recursive file transfer with streaming progress and cancellation, plus automatic SCP fallback, over the same SSH profiles as your terminals.
// Side by side
Mongrel vs Termius, feature for feature.
| Capability | Mongrel | Termius |
|---|---|---|
| Price and license | Commercial; annual plans from $99/year with a free 7-day trial | Subscription-priced, with a limited free tier |
| Desktop terminal depth | SSH, Mosh, Telnet, Serial, and local shells with logging, triggers, and recording | SSH and Mosh host management with a polished desktop client |
| Mobile apps | Desktop only; no iOS or Android client | iOS and Android apps are a core strength |
| Session import | Read-only Termius SQLite import, plus PuTTY/KiTTY and SecureCRT importers | Hosts sync through the Termius cloud account |
| Beyond the terminal | 30+ database engines, SFTP/SCP, Docker, Podman, Kubernetes, and an API client | SFTP alongside the SSH client |
| Sync model | Git-backed Connection Sync in a repository you control | Termius cloud account sync |
// Honest tradeoffs
Where Termius still has the edge.
Termius wins on mobile, full stop: its iOS and Android apps are the best reason to pay for it, and Mongrel has no answer there. Termius cloud sync is also zero-config, while Mongrel's git-backed Connection Sync asks you to point it at a repository. Mongrel is desktop software for people whose SSH work sits next to databases, files, and clusters; if your SSH work sits in your pocket, stay with Termius.
// FAQ
Frequently asked questions.
Is there a free Termius alternative?
Mongrel is commercial software with a free 7-day trial and no credit card required. If you need a permanently free terminal, open-source options exist, but they stop at the terminal; Mongrel's value is the workbench around it.
Can Mongrel import my Termius hosts?
Yes. Mongrel performs a read-only scan of the Termius SQLite database and tolerates schema drift. Passwords and private keys are re-entered after import and saved to the OS keychain; Mongrel never writes back to the Termius database.
Does Mongrel work on mobile?
No. Mongrel is a desktop app for Linux x86-64, macOS Apple silicon, and Windows x64 and ARM64. Termius keeps a genuine edge on iOS and Android; if your work lives on a phone or tablet, Termius fits better.
Does Mongrel support Mosh?
Yes, through a user-installed mosh binary. Mosh requires mosh-server on the remote host and UDP connectivity after the SSH bootstrap; port forwarding is not available over Mosh.
How does Mongrel sync sessions across machines?
Through git-backed Connection Sync: profiles land in a repository you control, with a history viewer and restore-to-revision. There is no required Mongrel cloud account, and credentials are stripped from exports by default.
