CVEDB vs FilterLists: common questions

Which is more reliable, CVEDB or FilterLists?

Only FilterLists is on our probe schedule so far (—% uptime over 90 days). The other is catalogued but not yet live-checked, so we can't compare measured reliability head-to-head — check the uncovered API's own status page for now.

Do CVEDB and FilterLists need an API key?

Neither needs a paid key — CVEDB is callable with no signup, and FilterLists is callable with no signup. Both are quick to prototype with; rate limits still apply.

Can I call CVEDB and FilterLists from the browser?

Neither sends browser-friendly CORS headers reliably, so call CVEDB and FilterLists from a server or proxy rather than client-side. The CORS and HTTPS rows above show exactly what we detected for each.

Are CVEDB and FilterLists free for commercial use?

CVEDB has unclear commercial terms, and FilterLists has unclear commercial terms. We track service terms and the data license as separate fields — see the Commercial use and Data license rows above, and confirm both before shipping either in a paid product.
