Built in the open,
for everyone
Spacewave is free and open-source software built by the community.
End-to-end encrypted
All data is end-to-end encrypted by default. Only your devices hold the keys.
Local-first, always
Your devices talk directly. Cloud relay and backup are optional and always encrypted.
Your data, wherever you want it
Most apps store your data in someone else's database. Spacewave runs on your device and stores data wherever you want.
Fully extensible
Add plugins, modify the source, or build something entirely new. Share your creations with others through Spacewave itself.
