  Concord Systems was acquired by Akamai Technologies in September 2016 and the
  concord.io domain is now parked/for-sale. The packages below are the company's
  original first-party client libraries. Those with a registry entry were verified
  live on PyPI / RubyGems / pkg.go.dev; the remainder exist only as source in the
  github.com/concord organization and are recorded as source-only. All are
  unmaintained (last releases 2015-2016).
