Needs review
Shortlist when you must browser-enable an existing Java Swing/JavaFX/SWT/NetBeans or Oracle Forms estate without a rewrite and can run a self-hosted session tier. Skip when you are building a greenfield web UI only, or when the app depends on video, 3D acceleration, or ultra-low-latency graphics. Consider Citrix/VDI or a hyperscaler cloud desktop when you need generic desktop remoting beyond Java UI toolkits.

STACKIT
Comprehensive IaaS: Compute and Storage
STACKIT's Compute Engine provides virtual machines and GPUs for workloads from general computing to AI training. Storage options include object for unstructured data, block for high-performance databases, file sharing, and automated backups. These run in EU data centers, offering low-latency access and scalability without vendor lock-in. Users benefit from predictable performance in regulated environments.
Managed Kubernetes and PaaS
The STACKIT Kubernetes Engine (SKE) deploys CNCF-compliant clusters with automated scaling and updates. Cloud Foundry supports application development and operations. Databases and messaging services like RabbitMQ integrate seamlessly. Developers focus on code while STACKIT handles infrastructure, reducing setup time and operational overhead for containerized apps.
Security and Observability Tools
Features like Secrets Manager, Key Management Service, and Network Security protect data at rest and in transit. Confidential Computing safeguards sensitive workloads. Logging via LogMe and Observability stack provide real-time insights. These tools ensure compliance and quick issue resolution, vital for industries facing strict audits.
Webswing
Browser delivery without rewriting Java UI
Runs Swing, JavaFX, SWT, NetBeans Platform, Applets, and Oracle Forms in HTML5 browsers over WebSockets with no required source changes. End users need a browser only, not a local JRE or plugin.
Customer-controlled self-hosted runtime
Install from a distribution ZIP or containers on your own servers, VMs, Docker, or Kubernetes. Standalone and Cluster Engine modes cover single-node pilots through multi-node scale-out with admin monitoring.
Incremental modernisation beside legacy screens
Modernisation Framework and JsLink let React, Angular, Vue, Vaadin, or APEX components coexist with Java UI so teams can rewrite modules over time instead of a big-bang cutover.
Enterprise auth and session operations
Pluggable security modules include SAML2, OpenID Connect, Keycloak, LDAP, and custom providers. Admin Console adds session mirror view, recording/playback, logs, and multi-tenant path isolation.
Built-in printing, files, and clipboard bridges
Browser-side printing with preview, isolated upload/download folders, and clipboard integration cover common desktop workflows that break in naive remote-app setups.
| Assurance & compliance | STACKIT | Webswing |

| US CLOUD Act exposure (indicative) | Nicht angegeben | Partial EU entity with no known US parent; self-hosted runtime keeps sessions on customer infra. Vendor website/portal lists US-group processor The Rocket Science Group LLC (email) plus Google/Meta/LinkedIn Ireland entities for analytics/ads. Not legal advice. |

| EU AI Act | Nicht angegeben | Not applicable Core product is application delivery/runtime, not an AI system. Prague research affiliate explores AI; not the catalogued product. |
| Considerations & known limitations | STACKIT | Webswing |
|---|---|---|
| Higher per-session server resources | Nicht angegeben | Medium Docs state each browser session needs more server CPU/memory than a native web app. Capacity planning and Cluster Engine matter for large concurrent user counts. |
| Video, 3D, and low-latency limits | Nicht angegeben | Medium Official overview: video not supported, limited sound, no 3D hardware acceleration, poor fit for real-time action games due to rendering latency. |
| Proprietary licensing since 21.1 | Nicht angegeben | Low Current releases require commercial license + SLA. AGPL/public source stopped after 20.2. Source access for licensed customers is via Client Portal rather than a public repo. |
| Vendor portal/marketing US-group processors | Nicht angegeben | Low Privacy policy lists The Rocket Science Group LLC and major ad/analytics vendors for website/portal data. Irrelevant to on-prem session pixels, but relevant if you put sensitive personal data only into vendor portals. |
| ISO 27001 not independently verified here | Nicht angegeben | Low Vendor claims ISO/IEC 27001-certified ISMS on the site footer. Ask for the current certificate and scope before treating it as verified. |

Best fit when

Poor fit when
Nicht angegeben
Webswing
Best fit when
- Enterprises and ISVs with production Swing, JavaFX, SWT, NetBeans, or Oracle Forms applications that must become browser-accessible without a rewrite
- Teams that can operate a self-hosted Webswing tier (on-prem, VM, Docker, or Kubernetes) and size CPU/memory per concurrent session
- Organisations planning incremental UI modernisation (React/Angular/Vue/APEX) while keeping proven Java screens online
- Buyers who want Irish/EU contracting (WEBSWING LIMITED) and customer-controlled residency for application sessions
- Public-sector or regulated estates retiring endpoint Java installs or reducing Citrix/VDI dependency for Forms/Swing only
Poor fit when
- Greenfield products with no existing Java desktop or Forms UI to preserve
- Multimedia, video, 3D-accelerated, or real-time action-game style interfaces (documented limitations)
- Teams unwilling to run and scale a server-side session farm for interactive users
- Buyers who require OSI-approved open source for the current release line (proprietary since 21.1)
Consider instead when
When: You need generic Windows/Linux desktop remoting rather than Java UI toolkit remoting
Consider: Citrix / enterprise VDI, or Microsoft Azure Virtual Desktop
Webswing FAQ positions itself as a narrower alternative to Citrix for Forms/Java estates.
When: You are rewriting the UI entirely and have no need to keep Swing/Forms screens running
Consider: Native web frameworks (React, Angular, Vue) or Oracle APEX without a Webswing bridge
Webswing's Modernisation Framework is for coexistence during migration, not a mandatory layer for new UIs.
When: You want a hyperscaler-managed browser app streaming control plane
Consider: AWS AppStream / WorkSpaces-class services or Azure cloud desktop offerings
Trade self-hosted EU software control for managed cloud operations.
Open questions for due diligence

Webswing
- Will Webswing provide the current ISO 27001 certificate PDF and statement of applicability scope?
- Is a customer DPA available for Client Portal / support data processing, and which subprocessors apply to licensed customers?
- Where is portal.webswing.org physically hosted, and are any non-EU regions used for backups?
- For your Forms/Swing edge cases (WebUtil, local devices, printers), which patterns are supported without code changes?
