About Castos

Castos was formed in 2017 around the Seriously Simple Podcasting plugin, a popular way of self-hosting podcasts. Castos added analytics, hosting, and an embeddable media player, and now provides automated transcription, a simple website, and allows content to be republished to YouTube.

On top of this, the company also provides podcast editing services.

About LibSyn

LibSyn is almost literally the first name in podcast hosting. They provide a rock-solid infrastructure and every possible feature you would expect from a mature platform. They have a huge user-base and run regular community events, many of whom are experienced podcasters who rely on LibSyn to run reliably.

LibSyn differs from most hosts in that it provides different RSS feeds for different apps and directories (as it calls them “destinations”) which is perhaps unnecessarily confusing, however when new directories and markets are opened up, LibSyn is almost always first in-line to adopt them.

The company is conservative in its development, often taking multiple years to roll out interface updates. This has meant they’ve fallen behind modern hosts whose designers and developers value user experience, however they offer support via email and they’ve been around for so long and have so many customers, that answers to most questions can probably be found in Facebook groups and Reddit threads.
