QueryLoL
Not another scoreboard. QueryLoL maps a per-level game plan for all 172 champions, calls out plays in real time while you play, and reads the enemy team — in a ~15 MB native app with no account and no telemetry.
Why it's different
A coach-style 18-level route vs your lane opponent, with the right action on each level — for all 172 champions.
Hands-free voice callouts: enemy missing, recall ready, objective spawning, jungler unseen — while your eyes stay on the game.
~15MB native Tauri app. No Electron, no account, no telemetry. All requests run locally from your machine.
Smurf scoring and premade/duo detection surface who you're really up against — before the game even starts.
The signature feature
Power curves, spike bonuses and ult strength are compared level by level against your specific lane opponent, then turned into one concrete action per level — "Lvl 3 trade", "All-in con R", "Farm side", "R2 + objective". The matchup phases sit on top, each level is edged green where you are ahead and red where you should play safe, and your spikes are marked.
In-game overlay
Hold TAB for a borderless overlay that thinks with you: a recall optimizer, wave-state advice, death-timer prediction, an enemy-jungle tracker, MIA alerts, vision targets, and a 5-level plan preview. The build strip shows owned / next / future with a gold-needed counter and a "READY" pulse.
Champion select & scouting
Runes, spells and items auto-apply the moment you pick, with alternatives labeled Popular or Best WR. Once your lane opponent is known, the build adapts to that matchup. On top of that: pick/ban scored 0–100, per-enemy matchup win rates, a lane-by-lane verdict on each ally, team-comp callouts, enemy threats with ward timings, and AD/AP damage composition for both teams — all on one screen.
After the game
Post-game breaks down both teams with MVP and multikill badges, a gold-advantage timeline, and per-phase (early / mid / late) splits. Your home dashboard benchmarks you against your own baseline and your detected role — so a support is judged on vision, not CS.
Game recording
Turn on Record games and every game is captured in the background, hardware-encoded so it doesn't cost you frames. Afterwards the timeline sits over your gold-lead curve with a marker for each kill, death, assist, multikill and objective — click one, or a death on the post-game chart, and the video starts 8 seconds before it.

Good to know
Yes — completely free and open source. No paid tiers, no ads, no account. The full source lives on GitHub.
QueryLoL only uses Riot's official local APIs — the League Client API and the in-game Live Client Data API — to read game state and apply builds you could set yourself. It never modifies, injects into, or automates gameplay, the same approach used by other popular companion apps.
Both. It's a native desktop app for Windows and macOS with automatic League client detection on each platform.
No account and no sign-up. QueryLoL reads your local League client directly and pulls public data from sources like OP.GG and Data Dragon.
Yes, if you turn on Record games. Each game is recorded in 1080p60 on your GPU (about 1.6 GB per 35 minutes) and opens in a review player where your kills, deaths, assists and objectives are markers you can jump to. The last 10 games are kept automatically, plus any you mark to keep. Available on macOS, and in beta on Windows — there, use Borderless or Windowed display mode.
It's built with Tauri (Rust) and uses your OS's native webview instead of bundling a full Chromium runtime like Electron or Overwolf apps — so it stays tiny and light on resources.
One small download. Every level mapped, every callout spoken, every lobby scouted, every game ready to rewatch.
