The backend layer your app plugs into — REST API, AI agents, auth, workspaces, permissions, and events log out of the box.
Qelos is the AI-first application layer gateway. It plays three roles for your app:
Manage data models, AI agents, users, workspaces, permissions, and events from a single dashboard.
RESTful endpoints backed by MongoDB. Blueprints define the data model; CRUD, AI chat, and auth come for free.
@qelos/integrator-* middleware makes Qelos the API for your Next.js, Nuxt, Express, Fastify, NestJS, or FastAPI app.
Install the CLI, drop in the integrator for your framework, and start calling the SDK.
Getting Started as an Integrator →Clone the repo, start the dev environment, and explore the admin panel.
Installation guide →Entities, AI agents, auth, permissions, workspaces, and events — one client surface.
Read the SDK reference →qelos init, qelos generate rules, qelos dev, qelos pull/push — your day-to-day developer tool.
Create agents in the admin panel, then embed them in your app via the SDK or web widget.
Open the AI agents guide →Per-framework setup guides for Express, Next.js, Nuxt, Fastify, NestJS, and FastAPI.
See available integrators →Expose tenant tools to Cursor, Claude, ChatGPT, and other MCP clients — configure access from the admin panel.
MCP setup guide →# 1. Install the CLI
npm install -g @qelos/cli
# 2. Initialize in your project (detects framework, scaffolds config)
qelos init
# 3. Install the integrator for your framework
npm install @qelos/integrator-next # or express, nuxt, fastify, nest
# 4. Install the SDK
npm install @qelos/sdkimport QelosSDK from '@qelos/sdk';
const sdk = new QelosSDK({
appUrl: 'https://your-qelos-instance.com',
apiToken: 'ql_your_api_token_here',
});
// Query entities defined in your blueprints
const products = await sdk.entities('products').find({ status: 'active' });
// Chat with an AI agent
const reply = await sdk.ai.agents.chat('agent-id', 'How can I help?');
// Check permissions
const allowed = await sdk.permissions.check('products:write');git clone https://github.com/qelos-io/qelos.git
