The short version

  • Only CKAN has a free tier, so it costs nothing to try first.
  • Each has a real cost: CKAN the package install path requires Ubuntu 20.04 or 22.04 64-bit specifically; other operating systems must use the source install; DataGrail no pricing is published, and while benchmarking suggests it undercuts OneTrust for comparable scope, cost still scales with request volume and connected systems, which grow with the business.
  • They diverge on capability: CKAN covers Dataset Management, DataGrail covers Live data discovery.
  • Prices and features above were last checked on 31 August 2026.

  • Self-hosting a data catalogue with harvesting and an APInot DataGrail

DataGrail

  • An organisation needing evidence for a regulator that deletion actually occurred in every system, not that a ticket was closednot CKAN

Where each one falls short

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

CKAN

  • The package install path requires Ubuntu 20.04 or 22.04 64-bit specifically; other operating systems must use the source install
  • Only Solr 9 and Solr 8 are supported, and from CKAN 2.10 they are the only Solr versions supported at all
  • A working deployment requires PostgreSQL, Solr, Redis, nginx, supervisor and uWSGI to be installed and maintained separately
  • Python 3.10 or later is required

DataGrail

  • No pricing is published, and while benchmarking suggests it undercuts OneTrust for comparable scope, cost still scales with request volume and connected systems, which grow with the business.
  • Automated fulfilment only works for systems with a supported connector, so homegrown applications and legacy databases still need manual handling, and those are usually where the awkward data lives.
  • Discovery works by observing integrations and traffic patterns, so genuinely isolated systems, offline data and files on employee machines remain invisible and outside the data map.
  • It is narrower than the enterprise privacy suites, lacking the assessment, third-party risk and wider GRC modules a large regulated organisation will also need, so it may be one of two platforms rather than the only one.
  • Deletion automation is irreversible and mistakes are unrecoverable, so teams need real confidence in identity verification before enabling it, and that caution often keeps deletion semi-manual for months after purchase.
