Build Craft
From SYSTEM to Agentic Application — Deployed Anywhere
Build Craft takes your Helix-validated SYSTEM of Agents and turns it into a full-fledged, production-grade agentic application. Deploy it on Nagent's managed cloud, host it in your private VPC, or run it entirely on-premise.
What Build Craft Does
Helix perfects the recipe. Build Craft serves the dish.
Once Helix has designed and validated your SYSTEM of Agents, Build Craft takes everything — the architecture, the prompts, the integrations, the evaluation results — and packages it as a deployable agentic application. You choose where it runs.
Visual Application Canvas
Assemble your Helix-validated SYSTEM on a drag-and-drop canvas. Configure each agent, wire integrations, set triggers, and define the application shell — all without writing infrastructure code.
Template Library
100+ pre-built application starters across every business function. Deploy a working agentic application in minutes, then customise from a proven foundation.
Prompt & Logic Studio
Built-in prompt editor with versioning, A/B testing, and diff views. Adjust agent behaviour, routing logic, and decision rules without touching your deployment.
Staging Environment
Run your full application against real or sample data safely before promoting to production. Full trace visibility, zero side-effects, instant rollback.
One-Click Deploy
Promote from staging to your chosen deployment target — managed cloud, your own VPC, or on-premise — with automatic monitoring configuration and version tagging.
Observability Dashboard
Real-time monitoring, per-run traces, latency metrics, KARMIC eval scores, and rollback capability. Full visibility into how your agentic application performs in production.
Deployment Modes
Your application. Your infrastructure. Your choice.
Build Craft supports three deployment targets — from zero-infrastructure managed cloud to fully isolated on-premise. The same application, the same quality, wherever you need to run it.
Managed Cloud
Fastest to shipDeploy on Nagent's managed infrastructure
Build Craft provisions, monitors, and scales your agentic application automatically. Your application is accessible as a web app, API endpoint, or embeddable widget within minutes of deployment.
- Zero infrastructure configuration required
- Automatic scaling based on usage
- Built-in SSL, CDN, and monitoring
- Shareable URL or embeddable component
- SOC 2-ready, encrypted at rest and in transit
Best for teams that want to ship fast without managing infrastructure.
Private VPC
EnterpriseDeploy inside your cloud environment
Build Craft packages your agentic application as a containerised deployment that runs entirely within your AWS, GCP, or Azure account. Your data never leaves your infrastructure boundary.
- Deploy to your AWS, GCP, or Azure VPC
- All data stays within your cloud account
- Bring your own model endpoints and databases
- Role-based access with your existing IAM policies
- Full audit logs within your own logging stack
Best for enterprises with data residency requirements or existing cloud governance.
On-Premise
Maximum sovereigntyRun entirely within your own infrastructure
For organisations that require complete isolation, Build Craft can package your application for on-premise deployment. No external network calls. No vendor access. Full operational independence.
- Air-gapped deployment option
- No data ever leaves your infrastructure
- On-premise model serving support
- Self-hosted monitoring and logging
- Fully auditable at the infrastructure level
Best for regulated industries, government, or high-security enterprise environments.

Deploy & improve
Ship to your chosen target. KARMIC and Smriti keep it improving.
Private VPC & On-Premise
Powered by Sovereign Agentic AI
Build Craft's VPC and on-premise deployment modes are built on Nagent's Sovereign Agentic AI framework — giving you full data residency, role-based access, and audit trails within your infrastructure boundary.

Validated before it ships
Build Craft only deploys what Helix has validated. Every application starts as a tested SYSTEM — not a prototype. The Helix validation score travels with the deployment, giving you confidence from day one.

Open the Studio, let Helix design and validate your SYSTEM, then use Build Craft to deploy it — to the cloud, your VPC, or your own servers.
