Playtest Analytics — Local Heatmaps, Session Replay & Reports

Know exactly where players die, quit, and struggle — without a server, a

subscription, or a cloud account.

Playtest Analytics is a fully offline playtest tracking tool. Drop one

component into your scene, call a few functions from your gameplay code,

and every session is saved locally as clean JSON — no setup, no backend,

no ongoing fees.

FEATURES:

- Death, Quit & Completion heatmaps — instantly see where players are

  struggling, overlaid on your level

- Session Browser — every playtest session at a glance: level, duration,

  deaths, quit/complete status, build tag, and date

- Heatmap filters — switch between Deaths / Quits / Completions / Custom

  Events, and between All Sessions or just the ones you've selected

- Session Replay — scrub or play back any player's actual movement path

  through your level

- Timeline event markers — jump straight to "2:03 Checkpoint" or

  "2:47 Death" during replay with one click

- Multi-session aggregation — combine 1 or 50 playtest sessions into one

  view, with per-level death breakdowns and average session length

- Build Comparison — put Build A vs Build B side by side: avg session

  length, deaths, quits, completion rate

- One-click HTML Playtest Report — sessions, averages, deaths/quits/

  completions, top problem areas, per-level stats, and an embedded heatmap,

  all in a single shareable file

- Custom event logging — track anything with one line: LogEvent("boss_hit")

- CSV export — pull your data into Excel or Sheets in one click

- 100% local — no account, no server, no recurring cost. Your playtest

  data never leaves your machine unless you export it.

- Plug-and-play — one component, works in editor or in builds

Perfect for solo devs and small teams running playtests who want real

answers about difficulty spikes and drop-off points — not a SaaS dashboard

they have to sign up for.
