VibeForces
Train and test the skill that actually ships software with AI.
VibeForces is a competitive platform for prompt-first software work. Learners solve practical challenges. Recruiters send timed tests. Every attempt is evaluated on correctness, prompt quality, token efficiency, speed, and engineering judgment.
For learners
Practice AI-assisted engineering tasks, get scored on output quality and prompt discipline, and build a Codeforces-style rating.
For recruiters
Create timed tests that measure whether candidates can direct AI, debug generated code, and reason through architecture.
Five kinds of challenges.
Each mode trains a different muscle that you'd use on the job — listening to a spec, hitting the answer with the fewest tokens, debugging, judging trade-offs, and rebuilding UI from a screenshot.
Spec-to-Prompt
A stakeholder rambles through a feature idea. You listen once and distill it into a prompt that survives ambiguity.
Token Golf
Land the correct output in the fewest tokens. Precision over padding — every word has to earn its place.
Bug Fix
Generic prompts score zero. Identify the real defect and direct the model to fix exactly that — nothing more.
Architecture Pick
Rank trade-offs the way pragmatic engineers do — when deadlines, scope, and cost are all real constraints.
UI Reproduction
One screenshot. One prompt. One shot. Rebuild the interface without iterating — the way real handoffs happen.
System design, multi-service prompting, and live pair-with-AI rounds are already on the roadmap.
A live challenge set across prompt precision, debugging, architecture judgment, and UI reproduction.
System design, multi-service prompts, and higher-order vibe coding interviews.
How a round works.
No setup, no install. Sign up, pick a challenge, and you're writing your first prompt in under a minute.
Pick a challenge
Five modes, three difficulties. Each one is a small task pulled from real day-to-day AI engineering work.
Write a prompt
You write the prompt. A frontier model runs it and returns an answer. No hand-editing — your prompt is what gets graded.
Get a rating
Another AI scores accuracy, token efficiency, and speed. Scores roll into a Codeforces-style rating on the global leaderboard.
Add AI-workflow testing to your hiring loop.
VibeForces is not here to replace interviews, DSA, or system design. It gives you one more signal: can this person use AI to understand a spec, write precise prompts, debug generated code, and choose sensible architecture under time pressure?
Start with one challenge.
Free, no card. Sign up, pick any challenge, and you'll have a real rating on the board in about ten minutes.
