Markdown Mermaid vs Shellter

Simple, lightweight and easy to use markdown and mermaid viewer. Use this for reading through documents you download or use a url.

Shellter is an SSH, SFTP and FTP client that keeps everything on your phone. There is no account to create, nothing syncs, and the app sends no telemetry. It opens connections to the servers you type in, and makes no other network request. That is the whole product. A REAL TERMINAL — An interactive shell rendered with xterm, not a toy console. It follows the keyboard, resizes the remote PTY when you rotate the phone, and keeps 10,000 lines of scrollback FILES WITHOUT A SECOND LOGIN — Browse, upload, download, rename, delete and create folders over SFTP or FTP. Open the file browser from inside a live SSH session and it reuses that connection instead of opening another one. A download never silently overwrites a file you already have. HOST KEYS, PINNED AND CHECKED — The server's host key is pinned the first time you connect and compared on every reconnect. If it does not match, the connection stops BEFORE authentication — your password is never sent to a server that failed the check. WHERE YOUR SECRETS LIVE — Passwords and private keys go into the iOS Keychain, hardware-backed where supported, stored "this device only" so they cannot be restored onto another phone. HONEST ABOUT PROTOCOLS — SSH and SFTP are verified by host-key pinning. FTPS is encrypted but does not verify the certificate. FTP is cleartext. Prefer SFTP.
