Evidence-Based Comparison Guide

How to Compare Domain Appraisal Tools in 2026

Hazlo, Estibot, GoDaddy, Dynadot, and Atom should be evaluated on equivalent outputs using the same frozen evidence—not unsupported vendor rankings.

What Hazlo's Current Benchmark Can Support

Hazlo's June 19, 2026 report is a deterministic calibration smoke test. It contains 18 approved-target rows and only two confirmed-sale points. It can expose Hazlo's misses and document one engine version.

It cannot prove that Hazlo is more accurate than another provider. No controlled cross-vendor test is published here.

Use the Same Comparison Criteria

Frozen Domain Set

Run every product on the same domains. Define category and TLD coverage before seeing results.

Confirmed References

Use verified public sales as authority. Keep human targets and third-party estimates in separate score groups.

Equivalent Outputs

Compare retail with retail, wholesale with wholesale, midpoint with midpoint, and range coverage with range coverage.

Dates and Missing Results

Record result dates, product versions when available, errors, unavailable outputs, and any manual intervention.

Symmetric Error Measures

Report percentage and ratio error, range coverage, medians, means, and severe tail misses for every tool.

Limitations

Disclose sample size, selection method, time effects, private deal terms, buyer-specific strategy, and data leakage controls.

Product-Specific Guides

These pages describe evaluation criteria and workflow differences. They do not assign unsupported accuracy scores.

Frequently Asked Questions

Which domain appraisal tool is most accurate?

This page does not name a winner because it does not contain a controlled same-domain, same-date, confirmed-sale test of every provider.

Can I use an automated appraisal as a guaranteed sale price?

No. A transaction also depends on the buyer, seller, timing, venue, negotiation, financing, and strategic fit.
