The short version

  • Only Umami has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Umami there is no cohort analysis, retention curve, session replay or multi-touch attribution, so a marketing team that needs to justify channel spend will still buy a second tool and Umami becomes a supplementary dashboard.
  • They diverge on capability: DataGrail covers Live data discovery, Umami covers Cookie-free tracking.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

DataGrail

  • A consumer brand whose deletion requests keep missing data in marketing tools the privacy team did not know existednot Umami
  • A company processing hundreds of CCPA requests a month where manual fulfilment has become a full-time jobnot Umami
  • A privacy team leaving OneTrust because the platform tracked requests but staff still completed them by handnot Umami
  • An organisation needing evidence for a regulator that deletion actually occurred in every system, not that a ticket was closednot Umami

Umami

  • A developer who wants traffic numbers on a personal or client site without adding a consent bannernot DataGrail
  • An organisation whose legal or procurement team has ruled out sending visitor data to a US advertising companynot DataGrail
  • A high-traffic site where hosted analytics priced by pageview band has become expensive and self-hosting removes the ceiling entirelynot DataGrail
  • A team that wants analytics data in a database they already control so they can query and join it themselvesnot DataGrail

Where each one falls short

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

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.

Umami

  • There is no cohort analysis, retention curve, session replay or multi-touch attribution, so a marketing team that needs to justify channel spend will still buy a second tool and Umami becomes a supplementary dashboard.
  • Self-hosting is only free in licence terms; you own the database, the upgrades, the backups and the query performance at scale, and a busy site's events table grows quickly enough to need real attention.
  • Because it stores no persistent identifier, it cannot follow a user across devices or sessions in any meaningful way, which makes returning-visitor and lifetime-value questions unanswerable by design rather than by omission.
  • Cloud overage is billed per event beyond the plan allowance, so a traffic spike or a badly instrumented custom event can produce a bill materially above the $20 or $200 headline before anyone notices.
  • It is maintained by a small team, so the pace of new capability is modest and enterprise expectations such as SSO, granular role permissions and formal support agreements are limited compared with commercial analytics vendors.

Answered from the vendors’ own pages

DataGrail: How is DataGrail different from OneTrust?

OneTrust orchestrates the workflow; DataGrail focuses on connecting to systems and completing the request, and benchmark data suggests it prices materially below OneTrust for comparable scope.

Umami: Is Umami really free?

Self-hosted, yes; it is MIT licensed with no event cap. You pay for the server and database. Umami Cloud has a free tier at 100,000 events a month and paid tiers from $20.

DataGrail: Does it find systems we do not know about?

Yes. Continuous discovery of unsanctioned tools processing personal data is its main technical claim.

Umami: Do I need a cookie consent banner?

For Umami analytics specifically, generally no, because it sets no cookies and stores no personal data. Other tags on your site may still require one.

DataGrail: What does it cost?

Not published. Pricing is quoted by request volume and connected systems, with multi-year commitments typically discounted.

Umami: Can it replace Google Analytics?

For traffic, referrers and event counts, yes. For attribution modelling, audiences and advertising integration, no.

DataGrail: Does it cover consent as well as requests?

Yes, it includes consent management, though publishers needing certified advertising consent usually use a specialist CMP.

Umami: What does it need to run?

A container and a PostgreSQL or MySQL database. Most people deploy it on infrastructure they already pay for.
