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.; Thought Machine a core replacement is a two to four year programme at an established bank, and the licence is a minority of total cost against system integrator fees, parallel running and data migration.
  • They diverge on capability: Eclipse IDE covers Java Development Tools (JDT), Thought Machine covers Smart contract product engine.
  • Prices and features above were last checked on 1 September 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.

Thought Machine

  • A core replacement is a two to four year programme at an established bank, and the licence is a minority of total cost against system integrator fees, parallel running and data migration.
  • The smart contract model presumes a bank can write and maintain Python financial products, and institutions without that engineering capability end up outsourcing the very flexibility they bought.
  • Cloud infrastructure cost sits with the bank and is not trivial at scale, so total cost of ownership comparisons against a hosted legacy core often miss a large recurring line.
  • Thought Machine has made two rounds of job cuts pursuing profitability, which is a legitimate supplier stability concern for a system a bank expects to run for fifteen years.
  • The functional footprint is core ledger and product engine, so origination, collections, regulatory reporting and channels all come from other vendors, and the integration estate around Vault is the bank's problem to design and own.

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.

Thought Machine: Is Vault Core genuinely cloud native?

Yes. It is containerised, runs on Kubernetes on public cloud, and posts in real time rather than in overnight batch.

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
Thought Machine: How long does a migration take?

Eighteen months at the absolute fastest for a narrow greenfield launch; two to four years for a phased migration at an established bank.

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
Thought Machine: Does the licence fee represent the total cost?

No. Implementation, system integration, parallel running and cloud infrastructure typically cost more than the licence over the programme.

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
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.
