Agents reach outside systems through a short, fixed set of built in routes. A cloud harness pushes to Git through a proxy that limits its credentials to the harness branch and refreshes them automatically, workload identity issues short lived tokens for AWS, Google Cloud and Azure, and workflow message steps post to Slack, a webhook or a pull request comment. Any other API key can be added to outbound requests at egress so the agent's code never holds it, but the tools that use it are the customer's own code, and agents get no integration catalog or tool framework.

Workflows chain builds, deployments, job runs, backups, conditions, approvals and messages in a visual editor or as JSON, with sequential, parallel and loop control and child workflows that can wait for completion, and the cloud agent loop carries agent built changes through previews, staging and production this way. A job can run an agent and the workflow waits for its result. These steps orchestrate releases and infrastructure around the agents, while the agent's own reasoning steps, hand offs and retries stay inside the customer's harness or code.

No retrieval index or knowledge base over the customer's content is part of the platform. Volumes, S3 buckets mounted through FUSE and managed Postgres, MySQL, MongoDB or Redis hold data that an agent's code can read and write, and any vector store or retrieval layer is something the customer deploys on top of them.

Release workflows can wait on people. An approval step holds a workflow until the required number of approvals is given from its run page, so an agent built change can be stopped before it reaches staging or production, and cloud harness pushes are confined to the harness's own branch. Nothing holds an agent's direct API, CLI or MCP actions for review, since those run with whatever the token's role permits.

Northflank holds SOC 2 Type II and ISO 27001 and supports HIPAA, with reports in its trust center. Fine grained roles grant create, read, update and delete permissions per resource type, can be limited to or excluded from projects, and drive API tokens, which inherit their role's permissions. Owner, admin and default roles come preset, organization roles span teams and can follow directory groups, and Enterprise adds SAML and OIDC single sign on with SCIM and just in time provisioning. Team policies limit which coding agents may run and can keep a harness private to its creator.

Every sandbox, job and harness streams logs and reports CPU, memory and network metrics through the dashboard and API, and workflow, job and template runs keep their run details.

On Enterprise, audit logs record every action from the UI, API and CLI, templates, release flows, Git events and the system, with the acting user, origin, affected resources, a before and after diff and the parent events that caused it, at organization, team, project and resource level, and forward to S3.

Log sinks, alerts and notifications to Slack, email, Teams or webhooks come on paid plans. An agent's prompts and tool calls inside its harness are not traced.

State outlives a single run. A cloud harness keeps its home directory on a 5 to 100 GB volume through restarts and pauses, sandboxes keep attached volumes across pause and resume, and S3 buckets mounted through FUSE keep data after a sandbox is deleted. Northflank's stateful agent example gives each agent a managed Postgres database for memory and resumes its session against it. That memory is a database and volume the customer's own agent code writes and reads, with no memory layer of stated scope and lifetime managed by the platform.

Projects run in one of more than 17 Northflank Cloud regions, chosen at creation and fixed afterwards, with GPU sandboxes in GPU enabled regions. BYOC runs the same sandboxes and harnesses in the customer's own AWS, Google Cloud, Azure, Oracle, Civo, CoreWeave or Nebius account, with Kata microVM support for harnesses, and Northflank also manages bare metal, OpenShift and VMware clusters. Enterprise can run the control plane itself inside the customer's infrastructure, air gapped if needed, so no platform data leaves the network.

Cloud harnesses come preset for Claude Code, Codex, OpenCode, Pi and Cursor, or start empty for other tooling, and a Northflank skill and plugin teach coding agents the platform. Stack templates deploy common applications in one step, and templates and preview blueprints package infrastructure and releases for reuse. These are configured third party agents and building blocks a developer assembles, not prebuilt agents of Northflank's own.

Work starts from Git events, schedules and webhooks. Workflows and preview blueprints run on a push, a pull request, a tagged release, a completed check suite, a pull request label, a cron schedule no more often than every 10 minutes, or a GET or POST to a webhook URL, with the branch, commit and pull request passed into the run. Jobs also run on cron schedules or on demand through the API, so an agent job can start on a timer or when another system calls it.

The customer chooses the agent and the model behind it. A harness runs Claude Code, Codex, OpenCode, Pi or Cursor signed in with the customer's own API key or account, or starts empty for other tooling, and team policies decide which of those agents a team may run. Models can also be self hosted on GPUs from L4 to B200 for inference beside the agents, and Northflank routes no model traffic of its own.

Every resource is reachable from outside through a REST API, a CLI, and JavaScript and Python clients, with endpoints for sandboxes, harnesses, jobs, workflows, templates, secrets, volumes and audit logs, plus exec, file copy, log tailing and metrics. A hosted MCP server takes a team API token as a bearer header and lets Claude Code, Codex, Cursor or OpenCode deploy services, manage jobs and databases and inspect resources. Templates and GitOps define the same resources as code.

There is no scoring, test case or quality gate for an agent's behavior. Sandboxes run reinforcement learning rollouts and evaluations at more than 50,000 environments in parallel from one image with shared volumes, but the rewards and scores come from the customer's own code.

Browser agents run on a browser image the customer picks, such as headless Chromium from browserless, with one sandbox per session that the agent drives over the private network through the DevTools protocol, behind egress rules set by domain. Northflank supplies the isolated compute and networking for it, not a browser or desktop of its own.
