Cloud Mode
Coming soon. Cloud mode is currently in development. Join the waitlist to get notified when it launches. Everything below describes the planned functionality.
Cloud mode runs your tests on Spark's managed infrastructure instead of your local machine. Same .spark files, same CLI — just add --cloud.
Your machine parses the test files. The cloud runs them. Results stream back to your terminal in real-time.
Local vs Cloud
Local mode
Runs on your machine using your Docker. Free, no account needed. Limited by your hardware.
Cloud mode
Runs on a fleet of workers with unlimited parallelism. 10-50x faster. Web dashboard with history and trends.
| Feature | Local | Cloud |
|---|---|---|
| Execution | Your machine, your CPU | Cloud fleet, unlimited parallelism |
| Speed | Limited by your hardware | 10-50x faster (more workers) |
| Output | CLI text + static HTML | CLI streaming + web dashboard |
| History | None | All runs, trends, regressions |
| CI | Exit code + JUnit XML | PR comments, status checks |
| Docker required | Yes | No — only the spark binary |
