Litestream
Litestream is a standalone streaming replication tool for SQLite. It runs as a background process and safely replicates changes incrementally to another file or S3. Litestream only communicates with SQLite through the SQLite API so it will not corrupt your database.
If you need support or have ideas for improving Litestream, please join the Litestream Slack or visit the GitHub Discussions. Please visit the Litestream web site for installation instructions and documentation.

Acknowledgements
While the Litestream project does not accept external code patches, many of the most valuable contributions are in the forms of testing, feedback, and documentation. These help harden software and streamline usage for other users.
I want to give special thanks to individuals who invest much of their time and energy into the project to help make it better. Shout out to Michael Lynch for digging into issues and contributing to the documentation.
Open-source, not open-contribution
Similar to SQLite, Litestream is open source but closed to code contributions. This keeps the code base free of proprietary or licensed code but it also helps me continue to maintain and build Litestream.
As the author of BoltDB, I found that accepting and maintaining third party patches contributed to my burn out and I eventually archived the project. Writing databases & low-level replication tools involves nuance and simple one line changes can have profound and unexpected changes in correctness and performance. Small contributions typically required hours of my time to properly test and validate them.
I am grateful for community involvement, bug reports, & feature requests. I do not wish to come off as anything but welcoming, however, I've made the decision to keep this project closed to contributions for my own mental health and long term viability of the project.
The documentation repository is MIT licensed and pull requests are welcome there.
