RAPTOR is a flowchart-based programming environment, designed specifically to help students visualize their algorithms and avoid syntactic baggage. RAPTOR programs are created visually and executed visually by tracing the execution through the flowchart. Required syntax is kept to a minimum. Students prefer using flowcharts to express their algorithms, and are more successful creating algorithms using RAPTOR than using a traditional language or writing flowcharts without RAPTOR.
Are you interested in running RAPTOR on Chromebooks, iPads, or just in a browser? Check out the pre-release here!. This is NOT fully tested. Send feedback via
A Multiplatform version of RAPTOR is now available for Windows, Mac and Linux built on top of [Avalonia]! See the downloads section below. Uses fonts from Noto Sans CJK for internationalization. Key differences:

Animations apply word by word. This works exceptionally well for captions, subtitles, and modern corporate presentations where readability is key.
For more complex motions (like glitch effects, 3D titles, or hand-drawn styles), they offer paid packs such as the "Text Presets Pack" which contains over 1,000 additional motions.
The magic lies in its . Unlike "baked-in" animations, these presets are procedural. You can change the timing, intensity, and direction of the movement through a dedicated panel, giving you professional results in seconds. Why Use Text Presets? 1. Massive Time Savings
Select your text layer in the timeline and click "Apply as IN" or "Apply as OUT."
A single preset style can yield completely different visual results based on how it breaks down your text. You can apply presets to animate:
Once applied, you can adjust the speed, intensity, and direction of the animation using the plugin’s user-friendly interface.
: These animate your text into the scene or out of it. You can choose to animate by characters , words , or lines , which is particularly useful for managing large blocks of text or paragraphs.
Ensure the text stays static on screen long enough for the viewer to read it twice. Utilize the "Continuous" presets very subtly so the text stays alive without causing motion sickness. Conclusion
How the text appears on the screen (e.g., fading, sliding, bouncing). Animate Out: How the text disappears from the screen.
Click the preset you like to apply it. The plugin automatically applies the animation to the layer. Customizing the Animation
: Presets can be replaced or removed at any time by clicking "Remove" or selecting a new preset and hitting "Replace".

Did you know RAPTOR has modes? By default, you start in Novice mode. Novice mode has a single global namespace for variables. Intermediate mode allows you to create procedures that have their own scope (introducing the notion of parameter passing and supports recursion). Object-Oriented mode is new (in the Summer 2009 version)
RAPTOR is freely distributed as a service to the CS education community. RAPTOR was originally developed by and for the US Air Force Academy, but its use has spread and RAPTOR is now used for CS education in over 30 countries on at least 4 continents. Martin Carlisle is the primary maintainer, and is a professor at Texas A&M University.
