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.; Semperis scope is limited to Active Directory, Entra ID and Okta, so an organisation whose critical identity lives elsewhere gets little from it, and the recovery value declines in direct proportion to how much has already moved off on-premises AD.
  • They diverge on capability: Eclipse IDE covers Java Development Tools (JDT), Semperis covers Active Directory Forest Recovery.
  • Prices and features above were last checked on 30 August 2026.

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.

Semperis

  • Scope is limited to Active Directory, Entra ID and Okta, so an organisation whose critical identity lives elsewhere gets little from it, and the recovery value declines in direct proportion to how much has already moved off on-premises AD.
  • The licence buys tooling, not a proven runbook: forest recovery is only worth what your last rehearsal demonstrated, and a plan that has never been executed end to end in a lab is an untested assumption regardless of what was purchased.
  • It overlaps with backup and directory management products from Quest, Veeam, Commvault and others, so the buyer must argue internally why a dedicated product is needed alongside a backup contract that already claims to protect Active Directory.
  • Running Directory Services Protector well requires someone who understands AD internals, replication metadata and Tier 0 attack paths, and without that person the alerts on privileged changes are either ignored or auto-reverted in ways that break legitimate administration.
  • Licensing is driven by identity object counts, so directories carrying years of stale user accounts and service principals pay for objects that should have been deleted, and the cleanup project that would reduce the bill is the one nobody has time for.

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
Semperis: Does this replace my backups?

No. It replaces the Active Directory recovery procedure specifically. You still need backups for everything else, and the point of Semperis is that a generic system-state backup of a domain controller is a poor way to recover a forest because it restores the operating system along with whatever compromised it.

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
Semperis: Is it useful if we are cloud-only on Entra ID?

Partly. Directory Services Protector covers Entra ID and Okta for change tracking and posture, but the forest recovery product, which is the strongest reason to buy, applies to on-premises Active Directory. A genuinely cloud-only organisation should weigh it against Microsoft's own tooling.

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
Semperis: Are Purple Knight and Forest Druid really free?

Yes, both are free downloads with no licence requirement, and they are widely used by organisations that are not Semperis customers. They are also, transparently, the top of the sales funnel.

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
Semperis: How long does forest recovery actually take?

The honest answer is whatever your rehearsal took. The vendor's case is hours instead of days, and automation genuinely removes most manual steps, but the number that matters for your board is the one from a test in your own environment.

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
Semperis: Does it require agents on domain controllers?

It collects directory changes from the AD replication stream, which is what lets it see changes that bypass the security log. Deployment details vary by product and version, so confirm the exact architecture against your domain controller change-control rules.
