Inspiring the next generation of creators

Thadus transforms coding education by teaching students how to think like programmers — building logic, structure, and problem-solving skills from the ground up.
Thadus is a simplified coding language, designed as a transitioning tool between block-based programming and traditional coding. It is also designed as the perfect low-pressure pathway into coding for all ages.
Bridge the learning curve between drag-and-drop block coding and professional text-based programming.
Keep learners motivated through engaging, challenge-based tasks that make learning feel like play.
No internet? No problem. Thadus works completely offline, ensuring data privacy and allowing students to learn anywhere in the world.

Thadus runs completely offline — simply install it on classroom or personal devices and start coding instantly, no login or internet required.
Students follow guided activities and coding sheets that help them transition from visual blocks to real text-based programming in a fun, hands-on way.
As learners spend more time exploring and creating with Thadus, they unlock milestone badges celebrating consistency, curiosity, and creativity — not test scores.
Thadus is designed to help students build real computational thinking skills before jumping into syntax-heavy programming languages.
With an individual subscription, learners progress through our courses step by step, at a pace that encourages deep understanding and confidence.
