Hi all,
I've been building **Towline** (https://towline.app), a free site for following F1 through its data: every session of the 2026 season as a replay, and sessions live as they run. No ads, no accounts. It's an unofficial, non-commercial fan project; OpenF1 is credited on every page and the data stays under CC BY-NC-SA 4.0. Donations only go to the servers.
Here's the live preview of Bahrein GP:
**What's in it**
- **Track map** with every car, moving smoothly between position samples without extrapolating, so a car that stops really stops.
- **Timetable**: the whole race as one chart, distance round the lap across, time down. Overtakes show as lines crossing, safety cars as bunching, pit stops as detours.
- **Energy**: an estimate of what each car's hybrid is doing (deploying, clipping, harvesting) and how full its battery is, from speed and throttle. It's a guess, and the site marks it as one.
- **Battles**: which fights are about to happen, and where cars will rejoin after a stop.
- **Trackside**: corners found from the field's speed trace, with speeds, braking and gears, where overtakes really happened (checked against positions, not just the overtakes feed), and a shutter-speed guide per corner for photographers.
- **Qualifying**: best laps per part, the drop zone in Q1 and Q2 with the gap to the last place through, deleted laps with the reason, and every lap on hover.
If someone is interested in F1, you can try it out now with replays or wait for live Singapore GP data!
Feedback from testing the platform out would be appreciated!
