There are several CS2 stats tools. Most track your match results — wins, losses, rating trends, round impact scores. That's useful context, but it doesn't tell you why you performed the way you did. NextFrag does something different: it analyzes the mechanics behind every shot you take.
The distinction matters. Knowing your accuracy dropped from 22% to 18% tells you something went wrong. Knowing that your counter-strafe clean shot percentage dropped from 62% to 48% tells you exactly what went wrong and how to fix it.
Upload any CS2 .dem file. NextFrag parses the demo using the Source 2 demo format, extracting every game tick relevant to aim mechanics:
Every shot event is correlated with your movement state at the time of firing. Were you stationary? Counter-strafing? Running? This produces your clean shot percentage — the most impactful single metric for competitive CS2. For a deeper dive on the timing layer, see CS2 counter-strafe analysis.
For every shot, NextFrag measures pre-shot aim movement and corrections around the fire tick: how far the crosshair traveled, and whether the final correction overshot or undershot. From this it derives reaction timing (measured from your view cone), your flick / tracking / static-hold split, and pre-aim quality at the moment you fire — measured from the demo, never guessed from what you might have seen.
Your accuracy in a long-range AWP duel is a different skill than your accuracy in a close-range spray. NextFrag breaks down accuracy by engagement type — flick shots, tracking engagements, and static holds — so you know which situations expose your weaknesses.
From your flick shot data, NextFrag calculates whether your current sensitivity causes systematic overshoot or undershoot. It reports a sensitivity multiplier with a reliability score based on sample size. High-reliability recommendations (50+ scored flicks) are statistically meaningful.
Aim Score: A single 0-100 score that measures your aim mechanics against professional play on the community scale — micro-adjustment quality, first-bullet precision, spray discipline and reaction timing. Raw accuracy alone doesn't move it, so it can't be padded by taking easier fights. It's the same Aim value you'll find on the leaderboard — one number, no tier labels.
Metric Breakdown: Each sub-metric with your value, the community median, and the professional benchmark. Instantly see where you're above or below average.
Sensitivity Assessment: Your current sensitivity's fit score with a concrete recommendation if adjustment would help.
First-shot Accuracy: The opening bullet of every duel is the cleanest mechanical signal in the demo. See CS2 first bullet accuracy for what it reveals.
Training Plan: A 7-day improvement plan targeting your specific weakest metrics. Not generic tips — targeted drills that address your measured data. The demo to training plan page walks through how to turn one analysis into a focused week.

Delta Tracking (Pro): With multiple analyses, NextFrag shows improvement or regression per metric over time. Track whether your training is actually working.

If you create an account, your analysis results are stored so you can track progress over time. Your demo files are still deleted — only the extracted metrics are kept.
The free tier gives you 1 analysis per day with your last 3 matches saved. That's enough to identify your weakest metric and start working on it.
Pro unlocks 5 analyses per day, up to 200 matches of history, 30-day progress tracking, PDF reports, and unlimited improvement goals. It costs from CHF 4.90/month depending on your region — less on the annual plan, and less than one competitive match's worth of time investment either way.
