Jumentix is an open-source software factory for teams building SaaS products. It provides contract-first foundations for APIs, realtime services, web applications, and modular product domains, so teams can concentrate on the product they are creating.

What You Can Build

• REST APIs with OpenAPI 3.1 contracts, plus WebSocket and gRPC realtime services.
• Function services for AWS Lambda, Vercel Functions, and Cloudflare Workers.
• Modular SaaS monoliths that can evolve into independently deployed service ecosystems.
• Complete product experiences: SPAs and offline-first PWAs with contract-driven client SDKs.
• Offline field and operations applications backed by IndexedDB and local storage.
• Domain models and service boundaries designed in Service Management, with service-specific OpenAPI and AsyncAPI exports.
• Services backed by in-memory, SQL, or NoSQL persistence adapters.

Why Teams Choose Jumentix

• The contract comes first. Every service is generated from an OpenAPI or Domain Designer model, so APIs, clients and documentation agree from day one.
• The code is yours. Jumentix generates a plain Bun workspace you read, change and deploy, on open-source libraries.
• Swap infrastructure, keep the domain. HTTP frameworks, databases and messaging sit behind adapters, so changing one does not touch your business rules.
• Start small, split later. Begin as one modular service and move domains into separate services when the product needs it.

Get Started

Create a project and answer a few questions about how it should run:

npx @jumentix/cli-init init my-product

Or generate the same project without prompts:

npx @jumentix/cli-init init my-product \
  --mode=monolith \
  --preset=users \
  --http=express \
  --realtime=none \
  --db=sqlite \
  --non-interactive

--mode picks the shape: monolith, services, hybrid (backend and web app) or frontend. Start from your own model with --from=<designer-export.json | openapi.yml>. Using Bun? bunx @jumentix/cli-init init my-product works the same way. The CLI guide lists every option.
