Documentation
co.build
Find apps, tools and firmware for your devices, with source code, compatibility notes and license terms.
co.build lists open-source apps, tools and firmware that change what a device you own can do: remove ads, keep your data, drop a subscription, or keep it working after the maker stops. Each mod has its source, license, per-model compatibility and owners' reports of whether it worked.
