Definition
A Developer Pro Sandbox is a sandbox environment that copies only the organization's metadata (no production data) and provides 1 GB of test data storage, compared to 200 MB in a standard Developer Sandbox. It is useful for development and testing tasks that require more storage space but do not need production data. Developer Pro Sandboxes can be refreshed once per day.
Real-World Example
a developer at Quantum Labs recently implemented Developer Pro Sandbox to build a custom solution that extends the platform beyond its standard capabilities. They write clean, bulkified code for Developer Pro Sandbox, add comprehensive test coverage, and deploy it through a CI/CD pipeline. The new functionality handles 10,000 records without hitting governor limits.
Why Developer Pro Sandbox Matters
A Developer Pro Sandbox is a sandbox type that copies only an org's metadata (configuration, code, layouts, and other Setup-defined components) without any production data. It provides 1 GB of test data storage and 1 GB of file storage, compared to 200 MB each in a standard Developer Sandbox. Like Developer Sandboxes, it can be refreshed once per day, supporting fast iteration cycles.
Developer Pro Sandboxes sit between Developer Sandboxes and Partial Copy Sandboxes in size and capability. They're appropriate when you need more test data space than a Developer Sandbox provides but don't need the production data slice that a Partial Copy or Full sandbox offers. Common use cases include integration testing with seeded test data, data load rehearsals, performance testing on synthetic data, and any development scenario where 200 MB isn't enough but production data isn't necessary. They consume one Developer Pro Sandbox license, which most paid editions include in limited quantities.
How Organizations Use Developer Pro Sandbox
- •Quantum Labs — Uses a Developer Pro Sandbox for integration testing where they need to load enough test data to exercise their integration code thoroughly. The 200 MB in a regular Developer Sandbox wasn't enough for realistic test scenarios.
- •TerraForm Tech — Maintains a Developer Pro Sandbox for data migration rehearsals. They load synthetic data matching production volumes and time their migration scripts before running them in production.
- •CodeBridge — Picks Developer Pro over Developer Sandbox when the team needs to test features that involve significant test data setup.
