@NGIZero just dropped the 2025 list of grant-funded FOSS projects, and there's some bangers this year!:

Here's 6 I'm super excited for in reverse order:
6. OpenStreetMap-NG
"a more accessible, privacy-respecting, and developer-friendly mapping platform."
"Our mission is to revolutionize the map and provide a better experience for all users. It is simply the Next Generation of OpenStreetMap."
My personal favorite (on tie with oaken/spritely) is ActivityPods:
https://nlnet.nl/project/ActivityPods-3.0/
ActivityPods brings together two game-changing protocols, ActivityPub and Solid Pods, and empowers developers to create fully-decentralized social apps thanks to an easy-to-use framework. In the planned version 3.0, Solid clients will be able to connect to ActivityPods just like any other Solid Pod provider.
