OSTerm — SSH Terminal

Osan Soft

About this app

An SSH terminal for people who carry their servers with them.

No ads. No in-app purchases. No account to create, and nothing collected about you.


■ Built for tablets

On a wide screen, the profile list and the terminal sit side by side. On a phone it folds down to one screen at a time.

Connect a Bluetooth keyboard and the on-screen keyboard gets out of the way. When you do need it, it never covers the terminal — the terminal shrinks to make room instead, so no output is ever hidden.


■ No limits

Unlimited connection profiles. Unlimited open tabs. Nothing locked behind a paywall.


■ CJK input

Type Korean, Japanese, and Chinese in the terminal. The keyboard opens in the language you set the app to, and a language toggle is provided for physical keyboards.


■ Sessions survive leaving the app

Switch to another app and come back — your session is still there. Start a long build or deploy and put the device down.


■ Everything you would expect

- SFTP file manager: upload, download, rename, delete
- Command snippets: save what you type often, run it in one tap
- Profile backup: export and import as a password-protected file
- Bundled coding fonts: D2Coding (fixed-width Hangul), JetBrains Mono
- Colour schemes and adjustable text size


■ Authentication

Password, private keys (PEM/OpenSSH), and keyboard-interactive. Import key files from your device and they are stored safely.

On first connection the host key fingerprint is shown for you to verify, and you are warned if a stored key ever changes. It is never accepted silently.


■ How your data is stored

Connection details never leave your device. The whole database is encrypted and its key is held by the Android Keystore. Passwords and key passphrases get a second layer of encryption on top.

Nothing is sent to the developer. This app has no server.


■ Languages

English, Korean, Japanese, Chinese (Traditional and Simplified), Spanish, Arabic
