Instant replay like OBS
The last seconds live in memory, already compressed by your graphics card. Ctrl+W and the clip is ready in under a second, with a sound cue.

Every fight, recorded.
Every fight, recorded.
Every mistake, in plain sight.
FREEno catch: every feature, for everyone
WZ Defender records your matches like OBS’s instant replay, but without OBS: it detects your kills and your deaths on its own, saves the clip of every scene with the killcam and keeps your stats: who you eliminate, who eliminates you, with which weapon and how you do in each mode. A single lightweight program that doesn’t touch the game.

Features
Everything that happens in your fights, saved
To get better at gunfights you have to watch them again. WZ Defender does it for you.
Lightweight, no dependencies
A single program: no OBS, no Moments, no Python. It uses Windows capture and your card’s encoder (HEVC, H.264 or AV1).
Detects your kills
Reads the “ELIMINATED” card: the enemy’s name and level and medals like HEADSHOT, LONGSHOT or DOUBLE KILL.
Detects your deaths
Reads the killcam and “KILLED BY”: who killed you, their clan, rank, level, weapon and how many shot you.
One clip per scene
A kill streak or a fight that ends in your death goes into a single clip, with the exact second of each event.
The whole match
Mode and map, pre-game lobby (its kills don’t count), start, your skull, final placement, wins and unfinished matches.
In-game overlay
Matches and wins per mode, kills in the match and in the day, and who killed you. It doesn’t touch the game and doesn’t show up in your clips.
Stats viewer
Your whole history in the browser: per day, per mode, your nemesis, who you eliminate the most, weapons that kill you and your clips.
HDR corrected
If you play in HDR, clips are converted to SDR so they don’t look washed out or dull.
Updates itself (with your permission)
Lets you know when there’s a new version and installs it with one key, signed by the author and with a backup.
How it looks
On top of the game and in your browser

Your day, without leaving the game

- Ctrl+O to show or hide it
- Doesn’t touch the game and doesn’t show up in your clips
Stats viewer
Your complete history
Today, 7 days, 30 days or everything, filtered by mode: matches, wins, kills per day, every match with its kills and deaths, your nemesis and your clips.
- Who kills you the most and with which weapon
- Who you eliminate the most and your medals
- Direct links to every clip

Frequently asked questions
Is WZ Defender free?
Yes, completely: no ads, no accounts and no locked features, like the rest of the WZ suite.
What does BETA mean?
That it already works and I use it myself every day, but it keeps growing and may have bugs. Every new version arrives with a notice and installs with one key.
Can I get banned for using it?
WZ Defender isn’t injected into the game and doesn’t read its memory or its network: it captures the screen like OBS and reads the HUD text with Windows’ text recognition. Even so, no third-party program can guarantee anything about the anticheat: use it at your own discretion.
Do I need OBS, SteelSeries Moments or Python?
No. WZ Defender is a single program that uses Windows screen capture and your card’s video encoder. You don’t need to install anything else.
Does it lower my FPS?
Very little: compression is done by your card’s video chip, just like in OBS. If your PC is modest, use the “light” profile (30 fps).
Does it work in exclusive fullscreen?
No: Windows doesn’t allow capturing exclusive fullscreen. Use “Fullscreen Borderless” in Warzone.
Where are my clips and stats saved?
In Videos\WZ Defender: one folder per day with Bajas (kills), Muertes (deaths) and Manual, plus the estadisticas.jsonl file with all your stats. Nothing is uploaded to the internet (unless you ask for the AI analysis of a clip).
Does it work with the game in Spanish?
The detector reads the HUD text in English. Set the game to English so it detects your kills, deaths and matches.

Did it help? Buy me a coffee ☕
The WZ suite is and will remain free. If it helped you gain FPS, hear footsteps better, understand your fights or your lag, a donation —any amount you like— helps me put more hours into it: testing on more PCs, adding features and keeping this site online.
Donating is 100 % optional: it doesn’t unlock anything, because nothing is locked.
