This is the mono repo for Rocicorp's two main products, Zero and Replicache.

rocicorp/mono is published from Rocicorp's internal repository. Each commit here comes from an internal commit, which the Mono-Internal-Commit: line at the end of the commit message records; internal commits that only touch private files aren't published. Releases of Zero are built and published from this repository.

Test suites are included for zero-client, replicache, zero-events, zero-react, zero-solid, shared and go. The test harnesses (helpers, fixtures, vitest configs and the Postgres test setup) are included for every package.

Tests for zero-cache, zql (including IVM), zqlite and some other packages are not included in this repository. These tests were previously published under the Apache 2.0 license, and those previously published copies remain open source under that license. They were removed from the published repository on September 30, 2026.

The history of this repository was rewritten on 2026-09-30 to remove the files that are no longer published. If you cloned or forked it before then, clone it again.

Pull requests are welcome. We don't merge them here: a maintainer ports your change into the internal repository, and it comes back here in a commit that lists you as a co-author and closes your pull request. See CONTRIBUTING.md.
