More than a decade after our founding, with thousands of customers and millions of users globally, JFrog has become the \u201cDatabase of DevOps\u201d and the de-facto standard in release and update management.","legalName":"Jfrog, Inc.","numberOfEmployees":{"@type":"QuantitativeValue","minValue":"1001","maxValue":"5000"}},{"@type":"Person","@id":"https:\/\/jfrog.com\/ja\/#\/schema\/person\/7da3329fbd14607d7b46e53df4ffdbb7","name":"akirau@jfrog.com","image":{"@type":"ImageObject","inLanguage":"ja","@id":"https:\/\/secure.gravatar.com\/avatar\/e5aa3f4b46b585be70fe5c5ce3aeb4d81decd40ca560f066c8f6d6c0327f26d2?s=96&d=mm&r=g","url":"https:\/\/secure.gravatar.com\/avatar\/e5aa3f4b46b585be70fe5c5ce3aeb4d81decd40ca560f066c8f6d6c0327f26d2?s=96&d=mm&r=g","contentUrl":"https:\/\/secure.gravatar.com\/avatar\/e5aa3f4b46b585be70fe5c5ce3aeb4d81decd40ca560f066c8f6d6c0327f26d2?s=96&d=mm&r=g","caption":"akirau@jfrog.com"}}]}},"_links":{"self":[{"href":"https:\/\/jfrog.com\/ja\/wp-json\/wp\/v2\/posts\/177727","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/jfrog.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/jfrog.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/jfrog.com\/ja\/wp-json\/wp\/v2\/users\/817"}],"replies":[{"embeddable":true,"href":"https:\/\/jfrog.com\/ja\/wp-json\/wp\/v2\/comments?post=177727"}],"version-history":[{"count":3,"href":"https:\/\/jfrog.com\/ja\/wp-json\/wp\/v2\/posts\/177727\/revisions"}],"predecessor-version":[{"id":177744,"href":"https:\/\/jfrog.com\/ja\/wp-json\/wp\/v2\/posts\/177727\/revisions\/177744"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/jfrog.com\/ja\/wp-json\/wp\/v2\/media\/166613"}],"wp:attachment":[{"href":"https:\/\/jfrog.com\/ja\/wp-json\/wp\/v2\/media?parent=177727"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/jfrog.com\/ja\/wp-json\/wp\/v2\/categories?post=177727"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/jfrog.com\/ja\/wp-json\/wp\/v2\/tags?post=177727"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
