03 · What Openunfurl can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

Limitations (from the README)

- v0.1 parses static HTML only - no headless browser, no JS-rendered SPAs. If a site renders its tags client-side you get the static fallback. - Best-effort per-instance IP rate limit - a soft abuse brake, not a guarantee (serverless instances are ephemeral and not shared). - SSRF-guarded - rejects localhost / private / reserved IP ranges. - MIT licensed and self-hostable - see below.
