When standard tools hit their limits.

Tools like Grafana are excellent for technicians, but often too complex for end customers or management. Those who want to monetize IoT data need their own interfaces.

The 'Admin Look'

Technical dashboards overwhelm users who aren't engineers. The UX is functional, but not intuitive or attractive.

Custom UX/UI

We build interfaces that hide complexity. Clear, modern and focused on user value (e.g., 'Is the machine healthy?').

Missing Business Logic

Standard platforms can't write invoices, invite users, or model subscription plans.

SaaS Features

Integration of user management, billing (Stripe/Chargebee) and access control (RBAC) directly in the web app.

Brand Experience

Your customer should see your brand, not the logo of a software vendor.

White-Labeling

From the login screen to the URL (portal.your-company.com) – the application looks 100% like yours.

What these apps can do technically

Features for IoT business models.

Fleet Management

Managing thousands of devices in list and map views. Status monitoring, firmware updates and configuration with one click.

Multi-Tenancy

Strict data separation. Customer A sees only their sensors, customer B only theirs. Perfect for service providers and OEMs.

Digital Twins

Visual representation of machines, buildings or facilities in the browser. Interactive floor plans instead of raw numbers.

Rule Engines & Alarms

User-friendly editors so your customers can create their own alarms ('If temperature > 50°C, send email to technician').

Modern. Fast. Maintainable.

We rely on proven web technologies that will still be standard in 5 years.

Frontend

React, Next.js, Vue.js – Fast loading times, SEO-friendly.

Backend

Node.js, Python – Direct processing of IoT streams.

APIs

REST, GraphQL, WebSocket – For real-time data without page reloads.

Infrastructure

Hosting on the merkaio cloud stack (Docker/Kubernetes).

What we build.

The OEM Customer Portal

A machine builder sells their equipment with 'Smart Monitoring'. The end customer logs in and sees OEE, downtime and maintenance intervals of their machine.

Smart Building Management

Facility managers see the status of 50 buildings on a map. Click on a building to open floor plans with live temperature and occupancy.

The Energy SaaS

A portal for tenants to view their own water and heat consumption (EED-compliant), including download of monthly statements.

No app without foundation.

The most beautiful frontend code is useless without stable data. Our web apps access merkaio ops infrastructure directly.

  • No synchronization problems.
  • Direct access to ThingsBoard or ChirpStack APIs.
  • High-performance queries from TimescaleDB or InfluxDB.

We're not an agency that connects to an API they don't understand. We build the API and the app.
