Gasjakten collects and displays prices for CNG (compressed natural gas) and biogas from public sources in Sweden.
The service is completely free to use — no account, no registration, and no hidden fees. There are no ads on the site and all functionality is available to everyone.
Public Data
All data displayed on Gasjakten is sourced from publicly available sources. Prices are published by fuel suppliers and retailers as part of their public pricing. Most prices are read directly from the providers' own websites; for some providers (e.g. OG Clean Fuels) their public web API is used. There, we reuse only individual price facts per station, with attribution and a link to the source.
We respect the public terms and robots.txt of our sources. If you represent a supplier and do not want your price data shown here, contact us via GitHub and we will remove it.
Manual baseline
For stations where the price cannot be read automatically, a manually researched baseline is used. These stations are marked "Manual baseline" in the service, and their prices are verified manually against the source — they may therefore be older than other prices. Always check the price against the source link before filling up.
Legal assessment
Our assessment is that individual price points are facts that are not protected by copyright (Lag 1960:729) and that the database right (Lag 1998:112) does not prevent the use of individual data points, as long as entire or substantial parts of a single supplier's data are not reproduced. This is our own assessment, not legal advice.
Transparency
Gasjakten values transparency and open information. By compiling public prices in an accessible way, we hope to contribute to a more informed vehicle gas market in Sweden.
Open API
The price data is freely available through an open API — no key or registration required:
| Endpoint | Description |
|---|---|
GET /api/prices | All stations with current price, change since the last change, source link and coordinates. |
GET /api/trends | Daily price series (30 days) per station. |
GET /api/prices/{provider} | Price history for a provider. |
GET /api/stats | Summary statistics (min/max/average by gas type). |
GET /api/health | Latest scrape status. |
The prices are individual factual data points (see the legal assessment above). The data is free to use — a mention of Gasjakten is appreciated.

The vehicle gas market is small and constantly changing. If we are missing a station, you can report it via the link on the start page — it helps us cover all of Sweden.
Reports are stored for at most 90 days and are then automatically purged. No IP address or other technical identifier is stored with a report. Submitting a report is voluntary — please do not enter personal data (about yourself or others) in the fields.

Privacy & data handling
There are no cookies on this website. No tracking or analytics services are used, and no personal data is collected or stored. Fonts, JavaScript libraries and stylesheets are served directly from gasjakten.se.
The exception is the map: when the map is displayed, map tiles are fetched from the OpenStreetMap tile servers (via CARTO), which means your IP address and technical request data are processed by those parties in order to serve the tiles. No map loading occurs before you open the map section, and no personal data about you is disclosed.
Local storage
The website uses browser local storage (localStorage) for the following purposes:
- Theme: Saves your dark or light theme preference.
- Install banner: Remembers if you have dismissed the PWA install banner.
- Map hint: Counts how many times a map navigation hint has been shown.
- Favorites: Remembers which stations you have starred.
- Price watching: Stores which prices you watch, to detect changes on your next visit.
None of this information leaves your device.
Location data
When using "sort by distance", your device's GPS location is used. Location data is processed entirely locally in your browser and is never sent to the server.
