Use sandboxes to reduce code conflicts, accelerate delivery, and safely test configurations without affecting other team members' work. Figure 1. How Developer Sandboxes work * Developer Sandboxes are isolated environments for parallel building and testing. * Each sandbox is provisioned on demand and fully isolated from others. * Every sandbox contains the full metadata of the base instance. * Sandboxes can be assigned to specific stories, developers, test plans, or custom criteria. {#exploring-sandboxes__ul_zw4_r3m_13c} ## Developer Sandboxes overview {#exploring-sandboxes__cf-exploring-parent-overview} Developer Sandboxes aim to provide lower-cost developer isolation and parallelism for customer development environments and instances. Developer Sandboxes are workflow-agnostic and are broadly applicable across workflows for both smaller and larger companies. Organizations can face challenges when addressing urgent defects and critical feature enhancements simultaneously in applications. Traditional shared development environments introduce risks such as code conflicts, configuration overlaps, and deployment delays, making it difficult to manage parallel workstreams efficiently. Development teams struggle to deliver urgent fixes and new features concurrently without disrupting each others' progress. The absence of isolated, independent development environments slows down delivery, increases rework, and hampers overall agility. Developer Sandboxes enables better development in the following ways: * Isolation: Each developer works in an independent sandbox, ensuring changes do not affect other team members' work. * Faster delivery: Teams can work concurrently, reducing development cycle time and enabling faster turnaround for urgent fixes and enhancements. * Safe testing: Developers can test configurations, workflows, and integrations within their sandbox without risking system stability. * On-demand provisioning: Admins and developers can quickly provision sandboxes for specific tasks or experiments without waiting for shared resources. {#exploring-sandboxes__ul_hc5_q4c_hgc} The Sandbox Management home dashboard displays the total, available, and allocated sandboxes in your instance. The dashboard also displays information relevant to each sandbox, including, the status, data utilization, owner, last accessed date, and when the sandbox was allocated. Check your entitlements to determine whether you have access to Developer Sandboxes. For more information, see [Developer Sandboxes entitlements](https://www.servicenow.com/docs/wiC0SoH2gMseFyrWRfQkjg "Your company's entitlements determine whether you have access to Developer Sandboxes."). Warning: Because sandboxes are retired automatically after an upgrade or clone, ensure any work that you want to keep is preserved before upgrading or cloning. * For upgrades, you can restore work from the remote update sets that Developer Sandboxes automatically created from prior sandboxes. * For clones, you must manually save and restore all work in sandboxes. * Any custom table configuration changes or fixes must be reapplied after an upgrade. Contact Now Support to open a case. For details, see [Cloning and upgrading considerations for Developer Sandboxes](https://www.servicenow.com/docs/p7J_qQ7ga5ajd7y0uVa8Ow "You should understand how plugins and sandboxes work before you clone or upgrade an instance with Developer Sandboxes. Back up your work in a sandbox before any clone or upgrade, either by exporting the update sets or committing to source control."). Build Agent is supported in Developer Sandboxes. For more information, see [Build Agent](https://www.servicenow.com/docs/fI1kj9rVymgaAzxpQYyEOA "The ServiceNow Build Agent application is an autonomous AI agent that creates and updates ServiceNow applications from natural language prompts. You can also use Build Agent to get answers to general ServiceNow development questions."). ## Integrate sandboxes with source control {#exploring-sandboxes__section_lcq_5hg_ggc} Developer Sandboxes provide an isolated environment that integrates with source control, such as Git. Using merge tools helps eliminate conflicts and enables parallel development. For more information, see [Source control and Developer Sandboxes](https://www.servicenow.com/docs/EcB_x3eXGBinQFYfrGWIwA "Use source control with Developer Sandboxes to enable parallel development and help avoid merge conflicts."). ## Developer Sandboxes users {#exploring-sandboxes__cf-exploring-parent-users} {#exploring-sandboxes__table_cw5_sqm_bcc__entry__2} | User | Description | |-|-| | Sandbox license admins | Sandbox license admins can assign purchased sandbox packs to non-production instances from App Engine Management Center (AEMC). | | Delegated developers | Delegated developers can request sandboxes from an admin or sandbox manager. | | Admins | Admins can allocate or retire sandboxes. | | Sandbox managers | Sandbox managers can administer the lifecycle of all sandboxes without full admin privileges. | | Sandbox users | Sandbox users can request and view Developer Sandboxes. | [Table 1. Users] {#exploring-sandboxes__table_cw5_sqm_bcc} Sandbox users use the same login credentials for their sandbox as the base instance. If you use Single Sign-On (SSO), enabling it on the base instance also authenticates Developer Sandboxes using the same credentials. For information on enabling SSO, see [Single sign-on for Developer Sandboxes](https://www.servicenow.com/docs/mjMpAPZLWEKZYm4wtN9h_A "Sandboxes use the same login credentials as the base instance, including single sign-on (SSO) when it's enabled there. Set the required properties on the base instance so developers can use SSO to access sandboxes."). Note: Instances with vanity URLs support SSO. ## Developer Sandboxes workflow {#exploring-sandboxes__cf-exploring-parent-workflow} The delegated developer or admin of a sandbox procures a sandbox, makes changes or experiments with development, tests their changes, pushes their changes, and waits for an admin to clone the instance. 1. A sandbox manager or admin allocates a sandbox to start story work. 2. The developer makes development changes and tests them out in their fully isolated sandbox. Note: The work done in one sandbox doesn't appear in other sandboxes or other instances. 3. Once the developer is content with their work and ready to promote their changes to a shared, integrated environment, they push their changes to the desired upstream shared instance. For example, a `test`/`QA` instance. There are two ways to promote changes: 1. Using source control (preferable) or exports through Git 2. Using update sets and imports. Update set sources between the sandbox and the base instance are automatically created when the sandbox is ready. For more information, see [Update sets transfer between sandboxes and base instance](https://www.servicenow.com/docs/gLMTiSeB8or1cI7s3xDMhA "When a sandbox is ready, update set sources are automatically created on both the sandbox and the base instance, enabling transfers in either direction without manual configuration."). {#exploring-sandboxes__ol_o44_3sf_dgc} 4. Further testing can be done on the shared instance. 5. The admin of a sandbox instance clones changes from the `test`/`QA` instance to make those changes the default for all future allocated sandboxes. {#exploring-sandboxes__cf-exploring-parent-workflow-ol} ## Developer Sandboxes benefits {#exploring-sandboxes__cf-exploring-parent-benefits} {#exploring-sandboxes__table_fw5_sqm_bcc__entry__3} | Benefit | Feature | Users | |-|-|-| | Enable parallel development | Enable multiple developers to work on different stories or features at the same time using the same starting source code, all while keeping the non-production baseline instance clean. | * Admins * Delegated developers * Sandbox managers {#exploring-sandboxes__ul_gqt_sjc_hgc} | | Reduce merge conflicts with source control | Enables integration with source control for more successful co-development. For more information, see [Source control and Developer Sandboxes](https://www.servicenow.com/docs/EcB_x3eXGBinQFYfrGWIwA "Use source control with Developer Sandboxes to enable parallel development and help avoid merge conflicts."). | Delegated developers, sandbox managers | | Self-serve license assignment | Assign purchased sandbox packs to non-production instances directly from App Engine Management Center (AEMC), without opening a support case. For more information, see [License assignment](https://www.servicenow.com/docs/FykpELup3edjBjt~m0tnlQ "License assignment in App Engine Management Center (AEMC) lets Developer Sandboxes admins distribute purchased sandbox packs across non-production instances without opening a support case. Each pack contains 10 sandboxes, and assignments are managed from a license management instance."). | Sandbox license admins | | Pooling for faster allocation | When allocating a sandbox, a sandbox is claimed from a pre-created pool rather than waiting for a new instance to be provisioned. The pre-created pool helps users start working in sandboxes faster. | * Admins * Delegated developers * Sandbox managers {#exploring-sandboxes__ul_rmt_ntc_2kc} | | Sandbox alias | Reference name for the sandbox you want to allocate. | * Admins * Delegated developers * Sandbox managers {#exploring-sandboxes__ul_nc3_w54_ghc} | | Allocate to | Enables you to allocate a sandbox to yourself, or for an admin to allocate a sandbox to someone else. | * Admins * Delegated developers * Sandbox managers {#exploring-sandboxes__ul_ibv_z54_ghc} | [Table 2.
