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.

Seeweb

  • KVM Cloud Servers with dedicated resources

    Cloud Server is a KVM virtual machine with dedicated CPU, RAM, and SAN-backed storage, N+1 style redundancy messaging, and guaranteed 1 Gbps bandwidth class. Scale vertically (add CPU/RAM/disk) or horizontally by composing multi-tier stacks. Unmanaged or fully managed by Seeweb engineers—fit for production web, DB, and agency workloads that need predictable isolation rather than noisy shared hosts.

  • GPU cloud for AI/ML (NVIDIA + AMD)

    Cloud Server GPU instances target training, inference, and HPC-style jobs with NVIDIA cards (H100, H200, A100, L40S, RTX A6000, L4 and related) and AMD options including MI300X. Ready-to-use drivers, Terraform support, hourly usage billing, and Spot Instances with a short preemption notice suit bursty or interruptible jobs. Data stays on European sites per vendor GDPR messaging—confirm region per SKU at order time.

  • Managed Kubernetes Service (SKS)

    SKS is Kubernetes-as-a-Service with a HA control plane, worker sizing you design with Seeweb, CSI storage (Vast Data driver on the product page), optional S3-compatible object storage, load balancing, and GPU workers (including MI300X and NVIDIA H-class cards). Aimed at teams that want orchestration without running etcd themselves; Proactive Support tiers add predictive monitoring for production clusters.

  • VPC, Foundation Server, and hybrid DC footprint

    Virtual Private Cloud builds private infrastructures on VMware or Proxmox; Foundation Server targets dedicated bare-metal-style capacity for business-critical virtualization. Combine with housing/colocation in Milan and Frosinone plus European partner sites for DR. Useful when you need private networking and dedicated hosts under the same Italian operator rather than public multi-tenant only.

  • ACN-qualified IaaS and CISPE EU residency claims

    Seeweb publishes ACN CSP qualification (QI2 infrastructure; QC2 for Foundation Server Pro, VPC, Shared CPU/High Memory cloud, and AI/supercomputing infrastructures) for Italian public administration procurement. CISPE Code of Conduct registration is used to assert customer data stored exclusively in European territories. Pair these claims with your own DPIA—they are procurement signals, not a substitute for a signed DPA.

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: Seeweb vs Webswing
Assurance & complianceLogo: SeewebSeewebLogo: WebswingWebswing
Independent security / no-logs audit

GDPR / EU data protection
Vendor claimed

Italian controller/processor entity, European hosting messaging, privacy policy, ISO 27018 claim, CISPE; confirm DPA for your processing roles.

Vendor claimed

Privacy policy names WEBSWING LIMITED as Irish controller under GDPR; FAQ states GDPR alignment for company contact data.

US CLOUD Act exposure (indicative)
Partial

Italian Seeweb S.r.l., Italian DHH parent, no known US parent; primary hosting on European DCs (not AWS/GCP/Azure). Third-party Swiss/BG facilities and global transit carriers exist. Indicative only—not legal advice.

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.

Data processing agreement (B2B)
Vendor claimed

Art. 28 DPA language used for Seeweb-operated services (e.g. published for Regolo); request current signed DPA + TOMs + subprocessors for core cloud/IaaS contracts.

Not found

Privacy policy references Art. 28 DPAs with Webswing's own processors; no public customer-facing DPA download found. Request during procurement.

EU AI Act
Partial

Infrastructure/GPU provider and Rethic.AI partnership messaging; AI Act duties mainly fall on customer AI systems. Not a full provider high-risk AI assessment by EuropeanStack.

Not applicable

Core product is application delivery/runtime, not an AI system. Prague research affiliate explores AI; not the catalogued product.

Considerations & known limitations: Seeweb vs Webswing
Considerations & known limitationsLogo: SeewebSeewebLogo: WebswingWebswing
Smaller global footprint than hyperscalers
Medium

Region set is European (IT/CH/BG) with a mid-size operator catalog. Multi-continent apps or niche managed PaaS may force multi-cloud or a larger EU peer.

Not listed
Certifications are vendor-published
Low

ISO and ACN claims include certificate numbers and dates on seeweb.it, but EuropeanStack did not re-download every registry PDF. Re-verify serials and scope statements in formal assurance reviews.

Not listed
No single public subprocessor register found
Medium

Facility partners and network carriers are described on DC pages, but a consolidated customer-content subprocessor list was not found as one public document. Request annex under NDA for regulated workloads.

Not listed
GPU Spot Instances can be interrupted
Low

Vendor documents ~2-minute notice before Spot termination when On-Demand needs capacity. Architect batch/checkpointing; do not run sole critical control planes only on Spot.

Not listed
Some sites use third-party data centers
Low

Lugano, Zurich, and Sofia are presented via partner facilities (Swisscom, Global Data Centers Switzerland AG, Evolink). Italy-only residency must be contracted explicitly if required.

Not listed
Higher per-session server resourcesNot listed
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 limitsNot listed
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 21.1Not listed
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 processorsNot listed
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 hereNot listed
Low

Vendor claims ISO/IEC 27001-certified ISMS on the site footer. Ask for the current certificate and scope before treating it as verified.

Fit

Seeweb

Best fit when

  • Italian PA and public-sector projects that need ACN-qualified IaaS (verify QI2/QC2 scope against the tender)
  • AI/ML teams wanting European GPU hours (NVIDIA H-class / L-class and AMD MI300X) with usage-based or Spot billing
  • System integrators and SaaS vendors that prefer managed Kubernetes (SKS) plus Italian engineering support over pure DIY clusters
  • Workloads that must stay under Italian/EU legal entities with CISPE-style European data-location claims
  • Hybrid designs combining Cloud Servers or VPC with colocation in Milan/Frosinone and European DR sites

Poor fit when

  • Applications that depend on dozens of global regions or proprietary hyperscaler PaaS (Lambda-style, global managed DB fleets)
  • Buyers seeking a free tier or purely self-hosted open-source cloud distribution without a commercial operator
  • Teams that need a published SOC 2 Type II report as a hard gate (not found on Seeweb certifications page)
  • Organizations that refuse any third-party facility (Swiss/Bulgarian partner DCs) without Italy-only contractual pins

Consider instead when

  • When: You need a large multi-country European cloud with denser product catalog and strong self-service DX

    Consider: OVHcloud or Scaleway

    Broader regions and developer tooling; less Italian ACN-specific packaging than Seeweb.

  • When: You want another Italian sovereign cloud with mass-market public-cloud SKUs

    Consider: Aruba Cloud

    Closest national peer; compare GPU/K8s maturity and PA qualification details side by side.

  • When: You mainly need simple self-service VMs/storage at aggressive commercial terms without Italian PA focus

    Consider: Hetzner

    Strong for general-purpose EU VMs; different compliance and support model.

  • When: You require global enterprise PaaS and marketplace ecosystems

    Consider: AWS or Microsoft Azure

    Accept US-group cloud and CLOUD Act exposure tradeoffs for breadth.

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

Seeweb

  • Will Seeweb provide a current signed DPA, TOMs, and full subprocessor list scoped to our SKUs and regions?
  • Can every required product (GPU, SKS, VPC) be pinned exclusively to Milan/Frosinone under contract?
  • What is the exact SLA and support tier mapping for our architecture (marketing cites up to 99.99%)?
  • Are current ISO certificate serials and ACN register entries still valid for the products we will buy?
  • Is IBM Spectrum Protect operated entirely on Seeweb infrastructure, or does any backup path leave European facilities?

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?
