Seriously Simple Podcasting
Castos lists its address as 1209 North Orange St., Wilmington, Delaware 19801.
What it is
Seriously Simple Podcasting is a WordPress plugin for publishing podcast episodes from WordPress when paired with Castos hosting. From the WordPress editor, publishers can distribute episodes to Apple Podcasts, Spotify, and major podcast directories, while managing the podcast RSS feed. A single WordPress site can manage multiple podcasts, each with its own feed, and the plugin includes episode-level statistics. Listed free add-ons include Genesis support, embedded transcripts, media player customization, and featured speaker boxes. The plugin is open source, and its page invites issue reports and pull requests. The plugin itself is free; Castos hosting is a separate paid service. Castos plans start at $19/mo, and a 14-day free trial does not require a credit card. Castos says its hosting stores audio and video on a CDN-powered platform, with triple-redundant backup and a global content delivery network on every plan. Listed integrations include Zapier, MemberSpace, Shopify, Elementor, Descript, Kit, Paid Memberships Pro, Stripe, PayPal, and MemberPress. Castos is headquartered in Wilmington, Delaware, United States.
