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:

The Mysterious Case of Lovita's Fate: Unraveling the Enigma
The late-November window in 2025 is dominated by blockbusters and critical darlings competing for end-of-year acclaim. Wicked: For Good
Without more context, I can’t assess quality, intent, or value. Please provide the actual item or media you want reviewed.
Lovita Fate owned a small shop at the corner of 23rd and 11th—numbered in the old way the city still remembered: 23 | 11 | 17. The brass numbers on her door had been hammered by her grandfather, who once said a person’s address could be a prophecy if you listened close. Lovita sold things people couldn’t get anywhere else: salvaged radios that hummed forgotten songs, jars of “summer-smell” candle wax that, when burned, made you feel as if you were standing barefoot on sun-warmed flagstones. Her sign read TALK TO ME in faded neon, part invitation, part warning.
She thought of her grandfather and the brass numbers and the way Fate had turned a prophecy into a marketplace of choices. Lovita smiled and said, “I listen for what’s missing. Then I sell what helps people find their way.”

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.
