The short version

  • Only Eclipse IDE has a free tier, so it costs nothing to try first.
  • Each has a real cost: Eclipse IDE startup time and UI responsiveness lag behind newer editors like VS Code.; IBM QRadar iBM sold the QRadar SaaS business to Palo Alto Networks in 2024 and those customers are being moved to Cortex XSIAM, so anyone buying today is choosing an on-premises product whose vendor has publicly moved the cloud future to a competitor, and the support horizon becomes a contract negotiation rather than an assumption.
  • They diverge on capability: Eclipse IDE covers Java Development Tools (JDT), IBM QRadar covers Offence model.
  • Prices and features above were last checked on 30 August 2026.

IBM QRadar

  • A regulated enterprise that must keep log data on premises or in a specific jurisdiction and cannot use a shared SaaS SIEMnot Eclipse IDE
  • A SOC that wants log correlation and network flow analysis in one platform rather than buying an NDR product separatelynot Eclipse IDE
  • An existing QRadar estate deciding whether to stay on premises or accept the migration path to a different vendor's platformnot Eclipse IDE
  • Compliance-driven log retention and reporting where the audit requirement is specific about collection, retention and reportingnot Eclipse IDE

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Eclipse IDE

  • Startup time and UI responsiveness lag behind newer editors like VS Code.
  • Plugin quality and compatibility can be inconsistent across versions.
  • Modern language support (e.g. for web frameworks) is weaker than dedicated tools.
  • Configuration and workspace setup has a steeper learning curve for newcomers.

IBM QRadar

  • IBM sold the QRadar SaaS business to Palo Alto Networks in 2024 and those customers are being moved to Cortex XSIAM, so anyone buying today is choosing an on-premises product whose vendor has publicly moved the cloud future to a competitor, and the support horizon becomes a contract negotiation rather than an assumption.
  • Licensing is by events per second and flows per minute, so every additional log source raises the cost directly and teams routinely exclude verbose sources such as DNS, proxy, endpoint and cloud audit logs to stay under the licence, which strips out exactly the data an investigation later needs.
  • It needs a dedicated operator: rule tuning, parser work and offence triage are continuous jobs, and an organisation that deploys QRadar without at least one named engineer accumulates thousands of unreviewed offences and a false sense of coverage.
  • A log source without a matching Device Support Module arrives unparsed, and writing a custom parser with regular expressions against an unfamiliar payload format is specialist work that can take days per source, which quietly determines which systems ever get monitored.
  • On-premises capacity is planned across consoles, processors, collectors and data nodes, so outgrowing the sizing means procuring and racking more appliances rather than changing a subscription tier, and growth becomes a purchasing cycle measured in months.

Answered from the vendors’ own pages

Eclipse IDE: Is Eclipse IDE free to use, including commercially?

Yes, Eclipse is released under the Eclipse Public License 2.0, a free and open-source license that permits commercial use with no purchase required.

Source
IBM QRadar: Who owns QRadar now?

It is split. IBM sold the QRadar SaaS assets to Palo Alto Networks in a deal announced in May 2024 and closed that September, and those customers are being migrated to Cortex XSIAM. IBM retains and supports the on-premises product.

Eclipse IDE: How do I extend Eclipse with plugins?

Extensions are installed from the Eclipse Marketplace, which hosts over 1,300 solutions spanning tools, languages, IoT support, and RCP applications, using drag-and-drop installation via the Marketplace Client.

Source
IBM QRadar: Is QRadar being discontinued?

IBM has committed to continuing support for on-premises customers, including security updates, while offering migration assistance. The cloud product's future belongs to Palo Alto. If you are signing a multi-year term, get the support horizon written into the contract.

Eclipse IDE: What license do Eclipse Marketplace plugins use?

Marketplace listings can be filtered by license type, including EPL, GPL, Apache 2.0, and MIT, since individual plugin authors choose their own licensing terms.

Source
IBM QRadar: How is it licensed?

By events per second for logs and flows per minute for network data, with the software or appliance sized to that rate. Add-on modules in the suite are licensed separately.

Eclipse IDE: Where can I get help with Eclipse?

Support channels include community forums, project office hours, and a contact page maintained by the Eclipse Foundation, in addition to the official Eclipse Platform help documentation.

Source
IBM QRadar: What is an offence?

QRadar's term for a correlated case. Rules group related events and flows against a common indicator such as a host or user, so an analyst reviews one offence rather than the hundreds of events behind it.

Eclipse IDE: Is Eclipse limited to Java development?

No, while Eclipse's Java Development Tools are its best-known feature, the plugin architecture and marketplace extend it to C/C++, PHP, JavaScript, and many other languages.

Source
IBM QRadar: Do I need a full-time engineer?

In practice yes for anything beyond a small deployment. Parser development, rule tuning and offence triage do not stop, and the most common failure mode is a well-installed QRadar that nobody has tuned since go-live.
