Three portals, one platform
Everything between your first array problem and your offer letter
Practice, prepare and get assessed without switching tools. Each portal writes to the same progress model, so what you solve on Monday shapes what the engine recommends on Friday.
Portal 01
Practice Arena
300 structured DSA problems.
One hundred Easy, one hundred Medium and one hundred Hard problems spanning arrays through advanced algorithms — each with formal I/O, worked examples, hidden tests and a full editorial.
Open Practice Arena- Monaco editor with C, C++, Java and Python
- Run against samples, submit against hidden and edge cases
- Progressive AI hints that guide instead of answering
- Reveal Answer with approach, intuition and complexity
Portal 02
AI Interview Prep
Personalized company-focused preparation.
Pick a target company and the adaptive engine reads your submissions, accuracy, hint usage and topic mastery to build a readiness score and a concrete plan for what to solve next.
Open AI Interview Prep- Company-style problem sets, honestly labelled
- Readiness score with strong and weak topic breakdown
- AI-generated problems that pass a validation pipeline
- Post-submission code analysis and solution explanation
Portal 03
University Assessment
Create, schedule and evaluate coding tests.
Faculty author their own problems and test cases, build a paper, assign 23 / 30 / 40 / 50 or any number of students, and let the platform mark every submission automatically.
Open University Assessment- Question bank with public, hidden, edge and stress cases
- Server-authoritative timer with automatic submission
- Partial scoring, ranking and class-wide analytics
- Structural code similarity as a review indicator
Built like production software
The parts that usually get faked, built for real
AI Learning
An adaptive engine that reads your real performance data and sequences the next topic and difficulty for you.
Multi-language Compiler
C, C++, Java and Python compiled and executed against every test case with per-case verdicts.
Secure Evaluation
Submissions run in an isolated sandbox with CPU, memory, process, filesystem and network limits.
Performance Analytics
Accuracy, streaks, topic mastery, coding time and assessment results in one continuous picture.
Progressive Hints
Three escalating nudges per problem — reframing, then technique, then algorithm outline. Never the answer.
Live Assessments
Countdown, autosave, mark-for-review and automatic submission when the server-side timer expires.
Question Bank
Faculty-authored problems with four classes of test case, reusable across any number of assessments.
Achievements
Milestones, streaks, difficulty masters and topic specialists that track genuine progress.
About
A learning platform that refuses to hand you the answer
DSA Forge is built on one principle: AI should make you a better problem solver, not a faster copy-paster. Hints escalate gradually. Solutions stay behind an explicit confirmation and never mark a problem solved. Generated problems are compiled and run against their own reference solution before anyone sees them.
For universities, every mark is computed server-side from verified judging results — timers, test ownership and student assignment are all enforced on the server, never in the browser.
Company-honest labelling
We never claim a problem was actually asked at a company unless it is verified. Everything else is labelled company-style or AI pattern practice.
Sandboxed execution
Submitted code never touches the application process, the database, or any secret. It runs in a disposable, network-isolated container.
Swappable AI provider
The AI layer sits behind one interface. Changing vendor or model is an environment variable, not a rewrite.
Integrity indicators
Similarity analysis flags pairs worth a human look. It never labels a student as cheating.
