A clean, zero-setup coding environment designed for focused algorithmic problem solving across 30+ languages.
Multiple languages
Assess skills across 15+ programming languages based on role requirements.
Automated test cases
Submissions are validated instantly against predefined test cases — no manual grading.
Consistent measurement
Every candidate is evaluated using the same standards, removing interviewer bias entirely.
Code execution without the hassle
When you need to quickly assess a candidate's grasp of data structures, algorithms, and core logic, our sandboxed Code Editor provides the perfect environment. It's fast, secure, and auto-graded.
Built for everyone in the hiring loop
Uniform criteria, early technical assessment, faster shortlisting — dependable outcomes for every role.
Engineering teams
Validate technical readiness upfront without spending time on repeated interviews or ad-hoc evaluations.
Recruiters
Shortlist candidates using real, role-relevant skill evidence instead of relying on resumes or surface-level screens.
Hiring managers
Review actual code outputs and problem-solving approaches, not subjective interview notes or summaries.
"Our engineering team was spending 15 hours a week on technical screens. The Code Editor handles it all — with better signal on candidate ability than whiteboard interviews ever gave us."
Questions, answered
What programming languages are supported?
The Code Editor supports 15+ languages including Python, JavaScript, TypeScript, Java, C++, Go, Rust, Ruby, PHP, C#, Swift, Kotlin, and more. You can configure language options per role to match your tech stack.
How are code submissions scored?
Submissions are automatically validated against predefined test cases. Each test case returns a pass/fail result, and the overall score is computed as a percentage of passing tests — giving you objective, consistent, and instant evaluation.
Can candidates use their own IDE?
No — and that's by design. The in-browser IDE provides a controlled, standardized environment so every candidate is evaluated under the same conditions. This eliminates variables like local setup, external tools, or pre-written code.
How do you prevent cheating?
The environment runs in a sandboxed browser tab with copy-paste monitoring, tab-switch detection, and session integrity checks. Combined with automated test validation, it's designed to ensure submissions reflect genuine ability.
Can I create custom coding challenges?
Yes. You can create custom problems with your own descriptions, constraints, input/output specifications, and test cases. This lets you evaluate candidates against the exact kind of work they'll be doing on the job.
