02The stack

Built on tools your team already knows.

Open, widely used technology, so your developers can read, change and host it from day one.

Web appNext.js · React · TypeScript

Pages rendered on the server. The browser never talks to the database directly.

BackendPython · FastAPI

One modular codebase: each app is a module with its own permissions, events and AI tools.

DataPostgreSQL · vector search

Every business's data kept apart inside the database itself, plus search across documents.

Background workRedis · workers

Emails, WhatsApp messages, imports and AI tasks run in the background, not while people wait.

AIProvider-neutral AI layer

Works with leading AI models. Every change is previewed and approved, and usage is counted per business.

MessagingWhatsApp Cloud API · email

Each client business on its own WhatsApp number, with email sent in its own name.

DeploymentDocker · automatic HTTPS

Runs on your own servers or cloud, with custom domains for your clients. Deployment guide included.

03The rules

Use it, change it, don't resell it.

Each copy carries a licence key and a buyer ID. Indian law applies, with arbitration.

You get the right to use the code, not ownership of it

Host DukeOS for your own named clients, under your brand

Change anything for your clients

No reselling the code, no public sign-up service, no removing the licence key

04Price

05Questions

Source licence questions.

Do we own the code?

No. You get the right to use and change it for your own named clients, for as long as your licence is active. SmartDuke keeps ownership.

What happens after the first year?

Your installations keep running under your licence. The first year includes updates and support; after that, hire us for support or new work whenever you need it.

Can we run DukeOS as our own public SaaS?

No. You can host it for your own named clients under your brand, but not run a public sign-up service or resell the code. Talk to us about Enterprise if you need more.

What do we need to run it?

A Linux server or cloud account with Docker. The stack is Next.js, FastAPI, PostgreSQL with pgvector and Redis. Setup help is available if you want it.

Can we try before buying?

Yes: we give you a sandbox to explore DukeOS as an agency, and a technical walkthrough of the code. Because the code can't be returned, there are no refunds once you have access.

Who pays for AI and WhatsApp?

Your clients' assistant runs on your own OpenAI or Anthropic key, and each business connects its own WhatsApp number. Those costs are between you, your clients and the providers.
