CodeSandbox vs Northflank

CodeSandbox is a web and iOS service for creating isolated development environments that execute code. Its SDK can spin up environments programmatically, while microVMs can be started, cloned, or restored from snapshots within two seconds. Snapshots let work resume in the same sandbox after inactivity, and users can set the inactivity period before automatic hibernation. Multiple agents can run in parallel without interfering, and forking supports A/B testing of different agents. Tests can run inside sandboxes for CI/CD, with environments able to hibernate after completion. Sandpack provides live browser coding, Storybook Integration creates a playground for each story, and CodeSandbox lists a VS Code extension. The service says it can handle millions of concurrent VMs. CodeSandbox was founded in 2017, is headquartered in Amsterdam, and CodeSandbox BV is a Together AI company.

Northflank is a developer platform for building and running applications made up of microservices, databases, background jobs, and scheduled tasks. It handles container builds, networking, and orchestration, and offers managed Kubernetes across North America, Europe, and Asia-Pacific. Deployments can use Northflank infrastructure, cloud accounts from AWS, GCP, Azure, Oracle, or CoreWeave, or imported Kubernetes clusters, including bare-metal and on-premises environments. Git integrations include hosted and self-hosted services; the platform also supports container registries and observability tools. Teams can use its UI, CLI, REST API, GitOps, reusable templates, pipelines, and preview environments. Northflank says secrets and files are encrypted at rest with AES-256, secrets are injected at runtime, and managed-cloud workloads use isolation controls. It states that it is SOC 2 Type 2 and HIPAA compliant; ISO 27001/27018 is listed as unavailable. The free Sandbox includes two services, one database, and two cron jobs with always-on compute. A payment method is required before creating resources, including on the free plan. Basic email support is included in all plans.
