Sold comps, compared honestly.
SoldComps and CompSniper are real, working products — and they are the reason Grail exists. This page states where each one wins. We do not claim we beat them everywhere; we claim the margin is made on trust, not marketing.

Where they win
Brand, distribution, and a polished dashboard. SoldComps has the SEO footprint; CompSniper has a clean UI. Both shipped before we did.
Where we win
Per-row provenance, grade-aware card identity, honest best-offer quarantine, and cache-first economics that make repeats ~free.
The honest caveat
Our live acquisition runs on an owned session pool that we scale with demand — not infinite. We publish our coverage and limitations instead of hiding them.
