An object-oriented dialect of the BASIC language, complemented by an integrated development environment and running on GNU/Linux and other UNIX-like operating systems.

It is a tool similar to Visual Basic in terms of developing Basic programs.

Gambas was conceived as an alternative for Microsoft Visual Basic developers who decided to switch to GNU/Linux

Geany is a small and lightweight integrated development environment.

The basic features of Geany are:
- syntax highlighting
- code completion
- auto completion of constructs like if, for and while, XML and HTML
- call tips
- many supported filetypes like C, Java, PHP, HTML, Python, Perl, Pascal
- symbol lists
- embedded terminal emulation

IDLE is an Integrated Development Environment for Python.
IDLE is written using Tkinter and is therefore available on different operating systems.

KDevelop is a free integrated development environment (IDE). There is source code navigation and debugging for projects in different programming languages, work with different build and version control systems, and all this is implemented on a modular basis.

KDevelop can analyze code in C, C++ and Javascript/QML, and there are also external modules for PHP and Python.

Lazarus is an integrated cross-platform software development environment in a Delphi-like environment in the Object Pascal language for the Free Pascal Compiler (often abbreviated FPC).
It is currently the only Rapid Application Development (RAD) tool that allows Delphi programmers to create GUI applications for Linux (and other non-Windows) systems.
Allows you to easily transfer Delphi programs with a graphical interface to various operating systems: Linux, FreeBSD, Mac OS X, Microsoft Windows, Android.

Thonny is a simple Python IDE with features useful for learning programming.

It comes with a debugger which is able to visualize all the conceptual steps taken to run a Python program (executing statements, evaluating expressions, maintaining the call stack). There is a GUI for installing 3rd party packages and special mode for learning about references.

Educational software designed to make learning programming easy and fun.

Greenfoot is an integrated development environment using Java or Stride designed primarily for educational purposes at the high school and undergraduate level. This makes it easy to develop 2D graphics applications such as simulations and interactive games.

Inkscape (an alternative to Corel Draw) is a vector graphics editor, convenient for creating both artistic and technical illustrations (including use as a general-purpose CAD program, which is also facilitated by the ease of sharing drawings). It is widely used to create illustrations, icons, logos, diagrams, maps, as well as web graphics.

It contains advanced tools for work, comparable to the capabilities of Adobe Illustrator, CorelDRAW and Xara Xtreme. You can read save images in many formats including SVG, AI, EPS, PDF, PS and PNG. Inkscape has a comprehensive set of tools, a simple interface, support for many languages, and is extensible with custom add-ons.

A simple drawing program for young children from 3 to 12 years old (eg kindergarten and primary school).
It is not an ordinary drawing tool. It's simple and fun to use. Sound effects and the animated nature of the program will help the user understand what is happening on the screen and will try to cheer him up.
You can draw using brushes or make shaped prints using stamps. For example, a teacher can make several animal figures and ask the children to draw the surrounding space in which they live.
Each shape has a melody and text prompts that are played and displayed when the child selects a shape.

Blender is a complex 3D modeling, animation, rendering, post-processing, interactive creation and playback (games).
With its help, static pictures, animation, models for games, as well as interactive information content in the form of independent programs are created.
It is possible to automate the program using Python scripts. In particular, import and export to popular file formats, such as 3D Studio and Wavefront Obj, are implemented in the form of scripts.
