Do you think we are missing an alternative of Cadence or a related project?
This repo contains the source code of the Cadence server and other tooling including CLI, schema tools, bench and canary.
You can implement your workflows with one of our client libraries. The Go and Java libraries are officially maintained by the Cadence team, while the Python and Ruby client libraries are developed by the community.
See Maxim's talk at [email protected] Conference for an architectural overview of Cadence.

Start the cadence-server
To run Cadence services locally, we highly recommend that you use [Cadence service docker](docker/README.md) to run the service. You can also follow the [instructions](./CONTRIBUTING.md) to build and run it.
Please visit our documentation site for production/cluster setup.
Run the Samples
Use Cadence CLI
Cadence CLI can be used to operate workflows, tasklist, domain and even the clusters.
You can use the following ways to install Cadence CLI:
- Use brew to install CLI:
brew install cadence-workflow
- Follow the instructions if you need to install older versions of CLI via homebrew. Usually this is only needed when you are running a server of a too old version.
- Use docker image for CLI:
docker run --rm ubercadence/cli:<releaseVersion>or
docker run --rm ubercadence/cli:master. Be sure to update your image when you want to try new features:
docker pull ubercadence/cli:master
- Build the CLI binary yourself, check out the repo and run
make cadenceto build all tools. See [CONTRIBUTING](CONTRIBUTING.md) for prerequisite of make command.
- Build the CLI image yourself, see [instructions](docker/README.md#diy-building-an-image-for-any-tag-or-branch)
Cadence CLI is a powerful tool. The commands are organized by tabs. E.g.
Please read the documentation and always try out
--help on any tab to learn & explore.
Use Cadence Web
Try out Cadence Web UI to view your workflows on Cadence. (This is already available at localhost:8088 if you run Cadence with docker compose)
We'd love your help in making Cadence great. Please review our [contribution guide](CONTRIBUTING.md).
If you'd like to propose a new feature, first join the Slack channel to start a discussion and check if there are existing design discussions. Also peruse our [design docs](docs/design/index.md) in case a feature has been designed but not yet implemented. Once you're sure the proposal is not covered elsewhere, please follow our [proposal instructions](PROPOSALS.md).
Other binaries in this repo
Bench/stress test workflow tools

Periodical feature health check workflow tools(aka Canary)
See [canary documentation](./canary/README.md).
Schema tools for SQL and Cassandra
The tools are for [manual setup or upgrading database schema](docs/persistence.md)
- If server runs with Cassandra, Use [Cadence Cassandra tool](tools/cassandra/README.md)
- If server runs with SQL database, Use [Cadence SQL tool](tools/sql/README.md)
The easiest way to get the schema tool is via homebrew.
brew install cadence-workflow also includes
- The schema files are located at
- To upgrade, make sure you remove the old ElasticSearch schema first:
mv /usr/local/etc/cadence/schema/elasticsearch /usr/local/etc/cadence/schema/elasticsearch.old && brew upgrade cadence-workflow. Otherwise ElasticSearch schemas may not be able to get updated.
- Follow the instructions if you need to install older versions of schema tools via homebrew.
However, easier way is to use new versions of schema tools with old versions of schemas.
All you need is to check out the older version of schemas from this repo. Run
git checkout v0.21.3to get the v0.21.3 schemas in the schema folder.
