There are at least a dozen FOSS platforms for phones now. Off the top of my head:
- Replicant
- Jolla
- Sailfish
- Lineage
- PostmarketOS
- Graphene
- e/os
Several more were mentioned in a recent FOSDEM talk. It’s becoming unsurmountable for someone to search on which OS works to what extent on what device. These FOSS platforms all have wikis and various ad hoc scattered datasets that are not in a proper importable format, like JSON or XML.
As always with FOSS, it’s disorganised. We need every portable platform project to publish a dataset in a standard format and ideally in somewhat standardized tables so folks can grab all the datasets to search more sensibly. I should be able to run an SQL command to show, e.g., what all platforms are available on phone model X which have wifi capability. And the reverse… I might want to say which phone has wi-fi support on the most linux-based OSs.
Personally I wouldn’t even need an app. Just datasets to import into SQLite. But an app would make the data useful for more people.
