As answered by people managing JavaScript Knowledge Map and Timeline Visualizer.
Timeline Visualizer's answer:
It runs entirely in the browser. You drop in the Timeline.json exported from Google Maps, and the video — your real route animating on a map, with date and distance counters and a final zoom-out — is rendered locally on your device. Nothing is uploaded to any server, which matters because location history is some of the most sensitive data you have. Every generated video comes out ready for social: 9:16 vertical MP4 with optional music.
Timeline Visualizer's answer:
Most travel apps are built for planning a trip or journaling during it, and they want your data in their cloud. Timeline Visualizer does one thing, after the trip: it turns the location history Google Maps already recorded into a shareable video. No account, no app install, no upload — open the site, pick a date range and music, export the MP4. The core is free; a $2.99 one-time Pro unlocks extras like map styles and custom markers, with no subscription.
Timeline Visualizer's answer:
Travelers who want to relive and share a trip — road trippers, backpackers, and anyone who came home and wondered what to do with the route Google Maps quietly recorded. It is popular for making Instagram Reels and TikTok recap videos, and it is available in six languages (English, Japanese, Korean, Indonesian, Vietnamese, and Traditional Chinese).
Timeline Visualizer's answer:
It started after a trip: Google Maps had recorded the whole route, but there was no good way to turn it into something worth sharing. The idea builds on the MIT-licensed open-source google-timeline-visualizer project — an Android app — rebuilt from scratch for the web so that anyone can use it without installing anything, and so the data never has to leave the device.
Timeline Visualizer's answer:
Next.js and TypeScript on the front end, deployed on Cloudflare. Video rendering happens client-side with the Canvas API and WebCodecs (H.264 MP4, with AAC audio muxed in without re-encoding). Map tiles come from CARTO.
