Our Technologies
We rely on proven and future-proof technologies to deliver your projects successfully.
TypeScript
TypeScript is dectria's standard in new projects – in the React and Next.js frontend, in the Node.js and NestJS backend, in Astro websites and in build and operations tooling. We work in strict mode.
Learn more
React
dectria builds business applications, dashboards and component libraries with React and TypeScript. React is the foundation of our web frontends – as a single-page application or as a full-stack application with Next.js.
Learn more
Next.js
dectria builds web applications, customer portals and SaaS platforms with Next.js. We work with the App Router, React Server Components and Server Actions, and we use TypeScript throughout – from the frontend to the API.
Learn more
Astro
dectria builds company websites, blogs and content platforms with Astro. Pages are generated as finished HTML at build time; JavaScript only reaches the browser where a component really needs to be interactive.
Learn more
Node.js
dectria builds backends with Node.js and TypeScript: REST and GraphQL APIs, integration layers to existing systems, document generation and automation. We have used Node.js in backend projects since dectria was founded.
Learn more
NestJS
dectria builds backends with NestJS: REST and GraphQL APIs with a clear module structure, roles and permissions, background jobs and documented interfaces. We use NestJS in production in our own products.
Learn more
PostgreSQL
PostgreSQL is our standard database for web applications, SaaS platforms and AI applications – in client projects as well as in our own products. We model data, optimize queries and set up backups, replication and access rules.
Learn more
OpenAPI / Swagger
dectria designs interfaces with OpenAPI and mostly works spec-first: the specification is written before the code and is the shared contract for frontend, backend and integration partners.
Learn more
Stripe
dectria integrates Stripe into web applications, apps and platforms: one-off payments, subscriptions, usage-based billing and marketplaces where payments flow to several providers. We process payment events via webhooks and transfer them reliably into your own systems.
Learn more
Authentication & SSO
dectria implements login, single sign-on (SSO) and user management for web applications, apps and SaaS platforms: sign-in with password, passkeys or a company account, tenants and roles, and automatic user provisioning from the customer's directory.
Learn more
Flutter
dectria builds apps for iOS and Android with Flutter – from one shared codebase, including publishing in the App Store and Google Play.
Learn more
React Native / Expo
dectria builds mobile apps with React Native and Expo when a team already works with React and wants to share logic, types or parts of the interface with a web application.
Learn more
AI Integration
dectria integrates large language models (LLMs) into existing software and business processes: RAG systems that answer based on your own documents, automated document analysis and data extraction, and AI agents that access your systems through interfaces. We process data in the EU or fully on premises.
Learn more
MCP
dectria builds MCP servers through which AI applications such as Claude, ChatGPT, Microsoft Copilot Studio or your own agents access your systems: reading data, finding documents, creating records. Every access runs through defined tools, with sign-in and the permissions of the respective user.
Learn more
Vercel AI SDK
dectria builds AI features in TypeScript applications with Vercel's AI SDK: answers that appear live in the interface, structured data following a fixed schema, tool calls, and agents that use functions of your systems.
Learn more
Cube.dev
dectria builds analytics and dashboards directly into applications with Cube: metrics are defined once, centrally, and are then available to dashboards, reports and AI agents with the same values and access rules.
Learn more
Docker
dectria packages applications with Docker into containers that run the same in every environment: in local development, in CI/CD pipelines and in production.
Learn more
Cloudflare
dectria hosts websites and web apps on Cloudflare and uses the network for DNS, certificates, protection against attacks and logic at the edge with Workers.
Learn moreVercel
dectria runs Next.js applications on Vercel, in client and in-house projects. Vercel develops Next.js itself, so Server Components, caching and middleware work there without extra configuration.
Learn more
Microsoft Azure
dectria builds and runs applications on Microsoft Azure: web apps and APIs on App Service and Container Apps, AI features with Azure OpenAI, and sign-in with Microsoft Entra ID. Azure is our first choice when a company already relies on Microsoft.
Learn more
Render
dectria runs backends, APIs, background jobs and databases on Render – for projects that need more than frontend hosting but no DevOps team of their own.
Learn more
Self-Hosting (Hetzner & Coolify)
dectria runs web applications, databases and staging environments on its own servers in the EU: on dedicated virtual servers at Hetzner, managed with Coolify. This keeps data with a European provider, and costs are fixed and predictable per server.
Learn more
On-Premise
dectria delivers software and AI applications for operation in your own infrastructure. Applications come as Docker containers that run on your own servers, in a private data center or in a hybrid environment.
Learn more
PostHog
PostHog combines product analytics, web analytics, session replay, feature flags and A/B testing in one tool. We use PostHog in our own products: NetCero, an ESG platform in which dectria holds a stake, uses PostHog for product analytics. This website measures with PostHog too – cookieless without consent, in full with consent.
Learn more
Resend
dectria sends transactional email with Resend: invitations, password links, notifications and reports from web applications and SaaS products. We use Resend in production in our own products.

Every project starts with a conversation.
