Streamlio

Streamlio was a real-time streaming and messaging company built around Apache Pulsar, Apache Heron, and Apache BookKeeper, surfaced as a portfolio company of lightspeed-venture-partners. The company was acquired by Splunk in October 2019 and is no longer operating independently; its former domains (streamlio.com, streaml.io) now resolve only to a MarkMonitor brand-protection parking IP that serves no content, its GitHub organization returns 404, and it exposes no first-party API surface. Its technology lives on as the Apache Pulsar, Heron, and BookKeeper open-source projects rather than as a Streamlio API.

Streamlio is profiled on the APIs.io network. Tagged areas include Company.
