Comparison
Metal Sentinel vs. Metals.dev
Metals.dev has a clean API surface but stops at raw JSON. Metal Sentinel layers in ready-to-embed price widgets, a WordPress plugin, daily editorial coverage, and per-metal landing pages your marketing team can link to.

When Metals.dev might still be the right call
We don't pretend every team should pick us. If you've already integrated Metals.dev, your traffic fits inside their free tier, and you don't need widgets, a WordPress plugin, or 180+ currencies, there's no urgent reason to migrate. The case for Metal Sentinel gets stronger the more of these you need: more metals, more currencies, embeddable surfaces, transparent pricing, and a primary Kitco-sourced feed.
