WZ-IT runs LimeSurvey as a dedicated instance in data centres in Germany, Switzerland or Austria, with updates, daily backups, 24/7 monitoring and a personal contact. On request, we also install LimeSurvey in your cloud or on premises.
LimeSurvey is an open-source platform for online surveys in businesses, research, education and public administration. Features, edition and operating architecture are adapted to participant volume, privacy and integration requirements.
With advanced features like conditional logic, question branching, customizable templates, and multilingual support, LimeSurvey offers maximum flexibility for your survey projects.
The self-hosted edition does not impose a typical SaaS quota on surveys and questions; practical limits follow from the version, resources and configuration.
30+ Question Types
Diverse question types from multiple choice to complex matrix questions and file uploads.
900+ Survey Templates
Professional templates for various industries and use cases for quick survey creation.
On-Brand Surveys
Complete customization with your own colors, logos, CSS, and JavaScript for your corporate design.
Multilingual Surveys
Support for 80+ languages for global survey projects and international audiences.
Privacy Controls & Security
Configurable anonymisation, permissions and documented safeguards for sensitive survey data. Legal assessment depends on the questionnaire and use case.
Infrastructure, integration and operations
LimeSurvey as part of your infrastructure
We do more than provide an application. WZ-IT designs the technical architecture, integrates network and identity, operates the agreed scope and develops integrations when the standard product is not enough.
Architecture and migration
Sizing, target environment, data transfer, cutover and recovery are resolved before production operations.
On-Premise
In your data center: Installation on bare-metal, VM or Docker · Integration with existing Active Directory/LDAP
Installation in your cloud
In your own cloud account, for example with AWS, Azure, GCP or Hetzner · Terraform/IaC setup (optional) · Kubernetes or Docker Compose · Capacity and scaling design
Enterprise Setup
Advanced architecture after technical and licence assessment: HA and recovery design where supported by the application and edition · Logging according to feature set and edition · Custom security policies
Network and identity
SSO, secure access, internal systems and existing security components are integrated appropriately.
VPN Access
WireGuard, NetBird, Tailscale, Headscale, OpenVPN, Cloudflare Tunnel · Easy client setup for all devices
SSO Integration
Directly or through an upstream identity layer
Multi-Factor Auth
Depends on application, edition and identity provider
Firewall & Hardening
Fail2Ban, Rate Limiting, IP Whitelisting
Monitoring and service level
Updates, backups, technical monitoring and response paths follow a transparent operational scope.
24/7 proactive monitoring
Updates and patches
Regular updates, CVE monitoring and prioritised patches for critical vulnerabilities
Daily backup with 7-day retention
Personal technical contact
Integration and development
APIs, automation and custom extensions can be delivered beyond basic deployment.
RemoteControl API
JSON-RPC API for full control: Create surveys, import participants, export results - all automatable.
Plugin Events
The plugin system offers events for every step: beforeSurveyComplete, afterResponseSave, beforeQuestionRender - for custom logic.
Custom Question Types
We develop new question types: Interactive sliders, image selection, complex matrix questions beyond standard.

Concrete Use Cases
LimeSurvey Development & Integration
LimeSurvey is powerful, but enterprise scenarios require deeper integration. We extend LimeSurvey for complex workflows.
HR Assessment Center
Problem
Application processes need standardized tests, but results must flow into HR system.
Solution
LimeSurvey as test platform with automatic evaluation and API push of results to SAP SuccessFactors/Workday.
Complex Branching Logic
Problem
Medical questionnaires need dynamic branching based on previous answers - standard isn't enough.
Solution
Custom expression engine that can evaluate complex conditions: 'If A AND (B OR C) AND score > 50'.
Certification Exams
Problem
Exams need time limits, random order, fraud protection - LimeSurvey standard doesn't cover this.
Compute, applications, storage and response are shown separately. You can see what ongoing operations include and which requirements need a technical assessment.

Business, Priority, Production and Critical include the first covered workload in a customer environment. Further covered workloads cost €29.90, €39.90, €49.90 and €59.90 per month respectively. For monitoring-only servers, we notify within the level's window for €14.90, €19.90, €24.90 and €29.90 per server and month respectively; without a service level, during service hours.
The flexible operations allowance applies to planned work during regular service hours and expires at month end. Operations, monitoring, backups, maintenance and updates within the agreed scope do not reduce it. Additional work beyond the agreed operations and the allowance, as well as further incident work, is billed at the hourly rate of the service level of the affected environment. The standard rate applies to commissioned work without a service level. Hour packages and fixed prices have their own prices. All prices are net and exclude statutory VAT. The offers are addressed to businesses.
Integrate LimeSurvey into your infrastructure with clear controls
A business application becomes a resilient part of the process landscape only when data flows, roles, communication paths and interfaces are clearly defined.
Teams and business processes
Employees, customers, partners and automated processes use defined roles and entry points.
Secure access
TLS, firewall rules, reverse proxies or private network paths are designed around the platform's exposure.
Identity and permissions
Local accounts, SSO, directories, service accounts and emergency access are connected through clear roles.
LimeSurvey platform
Business features, workflows, roles and configuration are deployed reproducibly and kept up to date.
Database and files
Business data, attachments, retention, export and consistent backups.
Communication services
Email, documents, notifications and optional background services.
APIs and business systems
Controlled connections to CRM, ERP, directories, payment or third-party systems.
The diagram is a resilient target model. Its implementation depends on edition, data flows, load, availability objectives and existing infrastructure.

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.
Yes. Besides Germany, Switzerland and Austria are available as locations, at the same prices in euros. The operator of the data centre in Switzerland is certified to ISO 27001, ISO 9001, ISO 14001 and ISO 50001 and sources electricity from renewable sources; the data centre in Austria is ISO 27001 certified. State the preferred location in your request; it is recorded in the proposal.
We typically provide a production instance within a few business days after signing. For a trial, we set up a test instance, usually on the next business day; it runs free of charge for 7 days and without payment details.
Yes. One .de domain is included with every hosting plan. Alternatively, connect your own domain or subdomain with a CNAME record.
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.
