FieldRat is a free Hubbl Diagnostics alternative for the field layer. Both surface underutilized fields — but Hubbl stops at the usage number. FieldRat builds the evidence for retirement decisions with where-used dependency analysis, a 0–100 risk score, and a retirement workflow, on any object, fully free.
Different altitudes. Hubbl Diagnostics is an org-wide health and technical-debt scorer — a great way to decide where to clean up. Its Field Utilization dashboard shows a usage percentage, but stops there. FieldRat is the tool that executes the field cleanup — dependency evidence, risk scoring, and an audit trail — on any object, fully free. This page compares them on the field layer.
What FieldRat adds
Hubbl's Field Utilization dashboard tells you a field is underused. It does not tell you whether it is safe to delete — no dependency map, no deletion risk, no retirement step, and the free tier is one scan a month. FieldRat turns the usage number into a ranked, evidence-backed retirement plan — where-used dependencies across 11–23 metadata types, deletion risk scoring, and a workflow to retire fields without breaking production, on any object, free.
Covers Flows, Apex, Triggers, Validation Rules, Formula Fields, Workflow Field Updates, Field Sets, Permission Sets, Layouts, Compact Layouts, and Quick Actions. Runs entirely inside Salesforce in seconds — no file upload, no record values leaving your org.
Adds Reports, Dashboards, Workflow Rules, Email Templates, and more — the references Quick Scan cannot reach. FieldRat generates the package.xml so admins do not hand-build the manifest.
Composite scoring across usage, dependency breadth, and critical-type hits. Turn an org-health finding into a ranked, field-by-field cleanup queue.
A searchable org-wide inventory of every object and field, with point-in-time exports for compliance review. Always free.
Pick any two completed runs and see field health movement: degraded, recovered, newly dependent, or cleared. Built for monthly governance reviews.
Track every field from discovery → review → approval → removed, with reviewer assignment, review dates, and an App Log audit trail.

FAQ
For field cleanup, yes. Both tools surface underutilized fields — Hubbl has a Field Utilization dashboard, FieldRat has Field Analysis. The difference is what happens next. FieldRat adds where-used dependency evidence across 11 to 23 metadata types, a 0-100 Deletion Risk Score, custom field limit tracking, and a retirement workflow with an audit trail — none of which Hubbl's field dashboard provides per its own docs. Hubbl remains stronger for org-wide health scoring. Validate current Hubbl packaging directly with the vendor.
Hubbl's Field Utilization dashboard shows a 0-100% usage figure per field, which flags underused candidates. Per Hubbl's own documentation it does not map field dependencies, does not score deletion risk, and does not delete or retire fields — and it can omit some fields and standard objects. Usage alone isn't enough to delete safely: a 0% field can still be referenced by a flow, formula, or integration. FieldRat scans those references and scores the risk before you retire anything.
Hubbl Diagnostics is freemium: the free tier is one scan per month per org with limited dashboards and results, and full access is paid (public pricing starts around $79/month). FieldRat is free with all packaged functionality included — unlimited runs, no per-user pricing, no credit card. Field Analysis and Field Dictionary are always free.
Use Hubbl Diagnostics for the high-level org health, security, and tech-debt assessment to decide where to focus. Use FieldRat to execute the field cleanup — confirm a field is unused, map what depends on it across flows, Apex, reports and layouts, then retire it with an audit trail. A health scorer tells you the org needs work; FieldRat safely does the field-layer work.
No. Quick Scan is 100% native to Salesforce. Deep Scan processes a metadata ZIP — schema, not record data — and the ZIP is deleted after analysis completes. Business record values never leave your org.
FieldRat is free. Field Analysis and Field Dictionary are always free. See where every field is used, score the risk, and retire safely.
