A free, in-browser alternative to Telemetry Overlay — for dashcam footage
Telemetry Overlay is a powerful, paid desktop tool for burning gauges onto action-cam video. If your footage is from a dashcam and you just want to see the route, speed and G-force — and maybe burn a simple speed-and-map overlay — dashcamigo does that free, in your browser, reading the GPS straight off the card. No $199 license, no install. For deep gauge production, Telemetry Overlay is still the more capable tool.
Open your recordingsWhat is Telemetry Overlay?
Telemetry Overlay (by Goprotelemetryextractor) is a paid desktop app for Windows, macOS and Linux that burns customizable speed, GPS and sensor gauges onto video and exports the result. It's action-camera-first — GoPro, DJI, Insta360, Garmin — with a deep gauge library and broad data-format support (GPX, FIT, NMEA and more), and an in-app map served by Mapbox. The full version is a one-time USD 199 purchase (down from $299, with a watermarked 3-day trial); dashcam GPS is read through a generic extraction path that's off by default. It's a render-and-export tool, not an interactive viewer for scrubbing a card full of clips.
Telemetry Overlay vs dashcamigo
Telemetry Overlay goes deeper on gauges. Here's where a free browser tool has the edge for dashcam footage specifically.
| dashcamigo | Telemetry Overlay | |
|---|---|---|
| Price | Free | $199 one-time (3-day trial) |
| How you run it | In the browser — nothing to install | Desktop install (Windows/Mac/Linux) |
| Reads dashcam GPS off the card | Automatically | Generic extraction, off by default |
| Built-in map | Keyless live map | Mapbox (keyed, paid-tier) |
| Speed & GPS overlay + export | Speed, coordinates, mini-map | Deep gauge library |
| Gauge depth & extra sensors | Speed, GPS, G-force | Hundreds of gauges, many sources |
Telemetry Overlay is the better tool when you want to produce a polished overlay video — it has a far deeper gauge library, supports action cameras (GoPro, DJI, Insta360) and many external data formats (GPX, FIT, NMEA), and exports broadcast-grade formats (ProRes, alpha PNG). dashcamigo's overlay is deliberately simple: speed, coordinates and a mini-map burned onto your dashcam clip. For action-cam gauge production, Telemetry Overlay (a paid, installed tool) is the right choice; for free, instant dashcam review and a basic overlay in the browser, dashcamigo fits.
Switching to dashcamigo
- Take the SD card out of the dashcam and plug it into your computer.
- Open dashcamigo.app in any modern browser.
- Drag the whole SD-card folder onto the page — it detects, groups and plays.
FAQ
Is dashcamigo a free replacement for Telemetry Overlay?
For dashcam footage, mostly: it reads the embedded GPS off the card, shows a live map and a speed/G-force chart, and can burn a speed, coordinates and mini-map overlay onto an exported clip — free, in the browser. It does not match Telemetry Overlay's deep gauge library, action-camera sources (GoPro/DJI/Insta360) or broadcast export formats. For a simple dashcam overlay it's a free alternative; for advanced gauge production, Telemetry Overlay is more capable.
Does Telemetry Overlay read dashcam GPS?
Yes, but through a generic extraction path that's off by default and must be enabled in Settings, with reliability varying by model. dashcamigo reads common dashcam GPS formats (70mai, Viofo, BlackVue, GoPro, Garmin, Vantrue, Thinkware and more) automatically when you drop the folder.
How much does Telemetry Overlay cost vs dashcamigo?
Telemetry Overlay's full version is a one-time USD 199 purchase (a watermarked 3-day trial is available). dashcamigo is free, with no account and no paid tier.
Can I use dashcamigo in the browser without installing anything?
Yes — open dashcamigo.app and drop your SD-card folder. Telemetry Overlay is a desktop app you install on Windows, macOS or Linux; it has no browser or mobile version.
Is the map free in dashcamigo?
Yes. dashcamigo's map is keyless MapLibre + OpenFreeMap, built in and free. Telemetry Overlay's in-app map and satellite imagery come from Mapbox, a keyed commercial provider, and map/GPS imagery is gated out of its free trial.
