Northflank vs Daytona: sandboxes, pricing, and infrastructure compared

Northflank and Daytona both provide isolated environments for running AI-generated and untrusted code. But as AI agents move from generating snippets to building and operating applications, sandboxing one agent process is no longer enough. The services, jobs, databases, and other workloads an agent creates can also be untrusted and need the same isolation, networking, resource controls, and observability.

Northflank has run production workloads since 2019 and production microVM sandbox orchestration since 2021, with isolated execution built into its multi-tenant platform. Today, Northflank Sandboxes and Cloud Harnesses provide isolated environments for AI agents and development, while the same control plane can run the applications and infrastructure those agents generate. Daytona focuses on programmable sandbox infrastructure for AI-generated code. This comparison looks at how the two platforms differ across isolation, lifecycle, startup and scaling, networking, GPUs, developer experience, infrastructure control, security, observability, and pricing.

Product and plan details are current as of September 2026.

Northflank uses Kata Containers with Cloud Hypervisor as its primary microVM approach, giving sandboxes hardware-level kernel isolation by default. Firecracker and gVisor are also available where supported and appropriate. CPU and GPU sandboxes use this isolation model alongside Northflank services and jobs, so isolated code execution sits within the same platform used to run the rest of the application stack. In BYOC, runtime availability depends on the provider, region, and node-pool configuration. Northflank does not currently offer Windows or macOS Sandboxes.

Daytona supports Linux containers, Linux and Windows VMs, GPU Sandboxes, and macOS Sandboxes on Apple silicon. Linux containers use the Sysbox runtime by default, while Kata Containers can be used when microVM isolation is required.

Northflank Sandboxes use a service lifecycle built around create, run, scale to zero, and destroy. Sandbox root filesystems are ephemeral by default, while persistent volumes can preserve repositories, datasets, models, and agent state across restarts. Scale-to-zero pauses compute billing while attached volumes are retained, and there is no fixed sandbox session duration. For repeatable environments, Templates and Workflows can reproduce the broader application topology, including services, databases, and multiple Sandboxes rather than just a single sandbox state.

Daytona supports sandbox lifecycle controls including stop, archive, delete, automatic lifecycle policies, ephemeral mode, and snapshots for reproducing sandbox state.

Northflank Sandboxes boot in under one second and can be created from Dockerfiles, Buildpacks, or external container registries. Horizontal autoscaling can scale workloads based on CPU, memory, requests per second, or Prometheus metrics, while BYOC adds node-pool scaling, spot capacity, and placement controls. In the ComputeSDK 2026 Scale Invitational, Northflank reported creating more than 100,000 concurrent 0.5-CPU Sandboxes from cold start in 24 seconds with zero failures, with P99 allocation of 566ms and P99 readiness of 733ms.

Daytona supports sandbox creation from Docker images, with published Linux container creation benchmarks below 90ms, as well as snapshots for reproducing sandbox state.

Northflank combines ephemeral Sandbox roots with persistent volumes, giving teams a choice between disposable execution environments and state that survives restarts. Sandboxes can use private DNS, public or private ports, multi-project networking, and network policies to control communication between workloads. BYOC also supports static egress IPs. Because Sandboxes run within the same platform as managed databases, services, and jobs, they can connect to PostgreSQL, MySQL, MongoDB, Redis, RabbitMQ, and MinIO through the same private networking layer.

Daytona provides per-sandbox volumes with isolation between sandbox mount paths, along with per-sandbox outbound network controls. Its firewall can block outbound traffic, allow specific CIDR ranges, or allow specific domains, while sandbox-to-sandbox networking is disabled by default unless explicitly linked. Inbound access can be exposed through preview URLs or SSH with the appropriate access controls.

Both platforms support GPU-backed sandbox workloads. Daytona supports NVIDIA and AMD GPUs. Northflank supports GPU-backed Sandboxes, as well as GPU-enabled services and jobs, with hardware including H100, H200, A100, L4, L40S, and B200 across managed cloud and BYOC configurations.

Northflank supports the full application workflow from source code to production, with Git-to-deploy, Dockerfiles, Buildpacks, external registries, Workflows, Templates, and GitOps. Teams can manage infrastructure through the API, CLI, or SDKs. Northflank Skills extend this workflow to Claude Code, Codex, Cursor, and OpenCode, allowing AI coding agents to deploy and manage workloads through the Northflank API and CLI, subject to credentials, RBAC, and audit controls. Northflank Harnesses provide dedicated cloud coding environments for AI coding agents with isolated resources and networking.

Daytona supports SDKs for managing sandbox lifecycles, files, processes, code execution, runtime configuration, and networking. Its REST API and CLI expose the same core functionality. Daytona's production codebase moved to a private repository in June 2026; its previous public repository remains available but is no longer maintained. The difference is primarily in scope: Daytona's tooling is centered on creating and managing programmable sandbox environments, while Northflank combines sandbox management with the tooling needed to build, deploy, automate, and operate the rest of the application stack.

Northflank supports self-service production BYOC, allowing teams to deploy the Northflank data plane into their own cloud account across AWS, GCP, Azure, Oracle, CoreWeave, Civo, and Nebius. The customer retains ownership of the cloud account, VPC, billing relationship, and existing cloud commitments, while Northflank provides the platform control plane and deployment tooling. BYOC can be set up without a sales process or annual contract, while Enterprise agreements can add assisted onboarding and SLAs where required.

Daytona also supports customer-managed compute through its Bring Your Own Compute model, where organizations attach their own runner nodes to custom regions managed through Daytona's control plane. Daytona BYOC requires an annual spend commitment, making the commercial model an important difference for teams evaluating customer-managed infrastructure.

Northflank also supports environments where the platform itself needs to run inside the customer's infrastructure. Its forward-deployed control plane can run the control plane, API, and audit database within the enterprise environment, which is relevant for regulated, air-gapped, or network-restricted deployments. Northflank therefore provides multiple infrastructure models, from managed Cloud to customer-owned BYOC and forward-deployed environments, while Daytona's infrastructure model centers on its control plane managing customer-provided compute.

Northflank provides security controls across both isolated workloads and the platform used to manage them. RBAC applies at the organisation, team, project, and resource levels, while SAML and OIDC SSO integrate with identity providers including Okta, Entra ID, and Google Workspace. Audit logs provide organisation-to-resource visibility and can be exported to SIEM systems. Northflank is SOC 2 Type 2 and HIPAA compliant, with Enterprise BAAs, while Enterprise deployments can use forward-deployed and air-gapped control planes for environments with stricter infrastructure requirements.

Daytona provides sandbox-level security controls including dedicated namespaces, resource quotas, filesystem restrictions where applicable, configurable outbound network policies, and an ephemeral mode that removes sandbox state when an environment stops. Daytona states that it supports SOC 2 Type 2, GDPR, and HIPAA requirements, with additional security controls available through its Enterprise offering.

For observability, Northflank provides logs and metrics across services, jobs, builds, and addons, alongside health checks, alerts, log sinks, and audit logs. Daytona provides telemetry and sandbox-level runtime visibility through its platform and APIs.

Northflank Cloud charges $0.01667 per vCPU-hour and $0.00833 per GB-hour, billed per second with no seat fees on Pay-as-you-go. The free Sandbox tier includes two services, one database, and two cron jobs with always-on compute. For BYOC, Northflank charges $0.01389 per vCPU-hour and $0.00139 per GB-hour, while the underlying cloud infrastructure is billed directly by the provider. This lets teams use existing cloud credits and committed spend contracts, and BYOC access does not require an annual commitment. Enterprise pricing is custom.

Daytona uses usage-based pricing with $200 in free compute and no credit card required to get started. CPU sandboxes are priced at approximately $0.0504 per vCPU-hour, billed per second, with memory and storage charged separately. Daytona's BYOC offering requires an annual spend commitment with enterprise pricing.

Assumes 200 continuously running CPU sandboxes, each with 1 vCPU and 4 GB/GiB memory, for 720 hours per month; excludes storage, network, GPU, and other charges.

Under these published rates and assumptions, Northflank's modeled CPU and memory cost is approximately 57% lower.
