Talk to a Chronicle server from a Kotlin or Java application with the io.cratis:chronicle client - connection strings, ChronicleClient and the Spring Boot starter, @EventType classes, suspending append, reactors and reducers dispatched by first-parameter type, model-bound and declarative projections, variants (@VariantOf/@EntersOn/@GlobalFor or variantOf()/entersOn()) for an entity with mutually exclusive lifecycle shapes, classpath artifact discovery, and the blocking API Java uses. Use when…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# The Chronicle client for Kotlin and Java

`io.cratis:chronicle` is a **standalone client SDK**. Your application is an
ordinary JVM application that happens to talk to a Chronicle server over gRPC.
There is no framework to inherit from and no application architecture imposed:
you construct a client, ask it for an event store, and append or observe.

## Verified product sources

Source: `Cratis/Chronicle.Kotlin`, by source symbols and signatures.

Read [references/product-sources.md](references/product-sources.md) when you need the artifacts and their source modules.

> **Do not copy a version number out of the repository's README or docs.**
> The version comes from a Gradle property injected at release time —
> `Source/build.gradle.kts` reads
> `providers.gradleProperty("version")` and defaults to `0.0.0-SNAPSHOT` — so
> the checked-in source never carries the real number. Take it from Maven
> Central.

> **The client and the kernel version independently.** `CompatibilityPreflight` checks contracts
> at connect and throws `ChronicleServerIncompatible`; do not infer a supported
> pair just because both products are "latest".

How to install

The exact contents, by fingerprint
mdr add cratis/ai/cratis-chronicle-client-kotlin@sha256:ce40b38e0b77ec23

The line at the top of this page pins the label git:20261014.d079312, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
