Go beyond "it works." Build the design skills and judgment that matter. A virtual engineering gym where you tackle real-world challenges and iterate through AI Tech Lead reviews.



Traditional coding platforms focus on algorithms. DevReel focuses on real-world engineering skills that actually matter in production.
No simple algorithms. Debug production incidents, resolve performance bottlenecks, refactor tangled dependencies, and handle security issues—real challenges from actual system operations.
Get scored on Functionality, Maintainability, Performance, Security, and Modern Syntax. Understand your strengths and weaknesses.
Not just "does it work?"—we evaluate why you chose that design. An AI Tech Lead reviews your decisions from maintainability and performance perspectives.
AI writes the code now. What matters is human judgment.
Basic coding skills alone won’t build a real product. To deliver continuous business value, you need the ability to resolve critical bugs, eliminate technical debt, and design architectures with strong maintainability and scalability.
But opportunities to build these mid-to-senior level skills tend to be concentrated in environments with large-scale traffic or exceptional mentors. Many engineers hit a wall: "I want to reach the next level, but I can’t see what experience I need."
DevReel is a virtual gym where anyone can simulate high-level, real-world engineering challenges—without depending on a specific environment or luck. Build your improvement loop through AI Tech Lead feedback and develop the fundamental engineering skills to thrive in the age of AI.
Three simple steps to level up your code quality.
Choose from real-world challenges like fixing bugs or refactoring legacy code.
No setup required. Tackle challenges in the built-in editor and explain your approach via voice recording or text.
Submit your solution and receive instant, detailed feedback on 5 key dimensions.
Start your own improvement loop—no special environment required. All features are free during the beta period.
