Which applications belong to AI & knowledge systems?

The category covers 45 applications in managed hosting. The most common types are Document-centric RAG platform (11), AI Interface (8), AI Agent (6), LLM Observability (3), AI Inference Engine (2), Data annotation (2).

How do I find the right application?

What matters is the use case (chat, search across your own documents, agents, evaluation), the connection to models and the licence. The catalogue lists Open WebUI and LibreChat as chat interfaces and Onyx, RAGFlow and Dify for knowledge search and workflows. We review the feature set, licence and edition and the operating effort before the proposal; vendor licences are listed separately.

What does hosting an application in this category cost?

Managed hosting costs from €99.90 excl. VAT per month for a standard workload of size XS. We check which size the application needs in production before provisioning. It includes updates, daily backups with 7 days of retention and 24/7 monitoring. Larger instances and higher service levels cost extra; the configurator calculates the price of the chosen configuration.

What is the contract term?

Hosting can be cancelled monthly, with no minimum term and 30 days' notice to the end of the month.

Where is the data stored?

Germany, Switzerland and Austria are available at the same prices. All three locations are data centres without US clouds that are ISO 27001 certified within the scope of the respective data centre operator; in Germany we additionally operate with a German provider whose data centres are BSI C5 attested. A confidentiality agreement under Section 203 German Criminal Code (StGB) is also available for app hosting on request, at the German location only; the separate Section 203 Managed Cloud for professional-secrecy holders is available in Germany only.

What applies to applications that are not in the catalogue?

We assess other actively maintained, self-hostable software before adding it to the operating scope. Describe the application in your request.

Operations

What matters in operations

The following points apply to many applications in this category.

Treat the application and the model separately
Usually the application is the interface; the model runs on a model server or behind an API. Where it runs determines the data flow.
Memory and compute
RAG platforms, vector indexes and embeddings can need more memory than a chat interface. We check the instance size before provisioning.
Fast release cycles
New versions of AI projects can change interfaces. Updates are checked for compatibility before they are applied.

Networking & Provisioning

WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.
