Chase Tracker — Zones, Obstacles & Escape Clocks for Tabletop Chases (Offline HTML)

Chases are hard to run on the fly. Chase Tracker puts quarry and pursuers on a visual zone track, rolls checks, drops obstacles and tells you when someone escapes or gets caught. Open one HTML file — no install, no account, no internet.

Features

• Visual zone track (8–15 zones) with draggable tokens for quarry and pursuers
• Live gap between the slowest quarry and the closest pursuer; escape at a gap you choose
• One-click checks — d20 + mod vs DC: Success +1, Great +2, Fail 0, Fumble −1 + complication
• Or resolve by hand with +1 / +2 / 0 / −1 buttons (use your own system’s dice)
• 7 environments of obstacles: city streets, rooftops, wilderness, dungeon, sewers, river/sea, desert — each with check, DC change and fail result
• 12 complications (dropped gear, bystanders, shortcuts …)
• Escape & Caught clocks that tick automatically on successes
• Obstacles placed on the track raise the DC for whoever moves into them; random obstacles on new rounds
• Chase log, auto-save, dark & light theme
• 100% offline, no libraries, no CDN, no tracking. Full readable source included.

System-neutral: use the built-in d20 rolls or your own system’s results with the manual buttons.
