Tabby is an infinitely customizable cross-platform terminal app for local shells, serial, SSH and Telnet connections.
It's not a remote connetions manager with multiprotocol.
This alternative is disputed. Tabby is a legitimate mRemoteNG alternative, but it might have issues that some users think are important.
ReTerminal is a sleek, Material 3-inspired terminal emulator designed as a modern alternative to the legacy Jackpal Terminal. Built on Termux's robust TerminalView.
Works quite well for SSH and Telnet but no RDP. Also it's not really open source as what's provided is very out of date and incomplete.
Say it with me: A Terminal is not a multi-protocol multitasking connection manager
