Flameshot is a free and open-source, cross-platform tool to take screenshots with many built-in features to save you time. Using Flameshot is as simple as launching, dragging the selection box to cover the area you want to capture, making annotations as needed in on-screen and saving the shot to your computer, all with a very simple and straightforward interface. Flameshot allows users to simply upload their screenshots directly to the cloud in order to easily share it with others. You can upload your image directly to Imgur with a single click and share the URL with others.
In-app screenshot editing - You can choose to add an arrow mark, highlight text, blur a section (blur or pixelate an area), add a text, draw something, add a rectangular/circular shaped border, add an incrementing counter number, and add a solid color box with Flameshot"s built-in editing tools.
Command-line interface (CLI) - Flameshot has several commands you can use in the terminal without launching the GUI via a command line interface. The command line interface lets you script Flameshot and use it as the subject of key binds.
