The short version
- Each has a real cost: ERPNext the software is AGPL-3.0 licensed, which imposes source disclosure obligations on anyone distributing a modified network service built on it; iDempiere there is no vendor, so there is no support contract, no service level agreement and nobody to escalate to; you either build the skills internally or you depend entirely on a local partner whose quality you must judge yourself.
- They diverge on capability: ERPNext covers Accounting, iDempiere covers Application dictionary.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
ERPNext
- The software is AGPL-3.0 licensed, which imposes source disclosure obligations on anyone distributing a modified network service built on it
- Managed hosting is priced per site and per server rather than per user, so a small team running several sites pays more than a large team on one
- Dedicated server isolation and stronger reliability guarantees start at $125 a month
- Self hosting is free but places upgrades, backups and availability entirely on the operator
iDempiere
- There is no vendor, so there is no support contract, no service level agreement and nobody to escalate to; you either build the skills internally or you depend entirely on a local partner whose quality you must judge yourself.
- It demands real Java, OSGi and PostgreSQL administration, so the running cost is a systems engineer rather than a subscription, and that engineer is harder to hire than a PHP developer.
- The ZK-based interface is dense and dated, with a data-entry feel inherited from Compiere that staff used to modern software find hostile, which drives up training cost.
- Localisation depends on community contribution, so tax, payroll and statutory reporting for your country may be absent, out of date or maintained by one person, and you may end up funding it yourself.
- The documentation is a community wiki with gaps and stale pages, and much of the practical knowledge sits in forum threads and partner heads rather than in anything you can hand to a new administrator.

Answered from the vendors’ own pages
ERPNext: Is ERPNext free?
Yes, ERPNext Community Edition is completely free and open source with no hidden paywalls. Everything is available to use, modify, or resell at no cost. Users can also access professional hosting through Frappe Cloud starting at USD$14 per month.
SourceiDempiere: Is iDempiere the same as ADempiere or Compiere?
It shares the lineage. iDempiere forked from ADempiere in 2011 to rebuild the platform on OSGi, and it is the branch that remains actively developed.
ERPNext: What is Frappe Cloud pricing based on?
Frappe Cloud pricing is compute-based rather than per-user licensing. Costs range from USD$14 to USD$108 per month depending on resource needs. The pricing advantage is that hosting costs do not scale linearly with the number of users, unlike traditional per-seat SaaS models.
SourceiDempiere: Is there a paid or enterprise edition?
No. There is no commercial owner and no feature gating. Money is spent on implementation partners and hosting, not on licences.
iDempiere: What does it actually cost to run?
Nothing in licence fees, and a great deal in skills: expect a partner implementation and ongoing Java and PostgreSQL administration, which for a mid-sized company is comparable to a commercial subscription.
iDempiere: Which database does it need?
PostgreSQL or Oracle. PostgreSQL is the mainstream community choice and the one most partners deploy.
