tinyterm is a free, native terminal for SSH, serial ports and the local shell, built for people who work with embedded devices. Next to the terminal, serial sessions get a data-studio view: live plots, dashboard tiles, a hex view, a timestamped log and a binary frame parser. It runs on Linux, macOS and Windows.
