JaVers is an Apache-licensed open source project and it’s completely free to use.
JaVers is gaining momentum, the number of downloads from The Central is growing.
In 2026, javers-core reached 1.6 Million monthly downloads.
However, the effort required to maintain Javers and develop new features is also increasing. Burnout among maintainers is a serious risk in open source projects, especially when we work for free.
Our work is not sustainable without financial backing.
