Castos Review 2026

A podcast hosting platform with WordPress integration and YouTube republishing features.
TL;DR
Two things make Castos worth a look: unlimited hosting and the way it auto-republishes your episodes to YouTube. Add WordPress integration, private podcasting, team roles, and an AI assistant, and it's a tidy package for people who take the show seriously. No free plan ($19/mo), the analytics aren't IAB-certified, and marketing is light.
Quick Takeaways

What is Castos?
Castos has been a remote-first US company since 2017, pitched at people who treat their podcast as more than a hobby. Two features are why it stays on my radar: WordPress integration and automatic YouTube republishing.
The integration runs through Seriously Simple Podcasting, a plugin built specifically for Castos, so you manage episodes and embed players without leaving WordPress. The YouTube piece is the one I keep mentioning to people, on the Growth plan and up, it turns your audio into video and posts it to YouTube for you, which quietly removes a chore most podcasters keep putting off.
Private podcasting with subscriber management is there for membership communities, internal company shows, and paywalled content. The AI Assistant is a $10/month add-on for content generation and transcription, and clips come via a Headliner integration rather than anything native.
The analytics do the job, downloads, episode comparison, audience by platform, device and country, playback duration, but they're not IAB-certified, and that matters the moment you start talking to advertisers. On the plus side, Premium scales to unlimited team members, and custom domains kick in from Growth up.
So the trade is clear: $19 to start with no free tier, uncertified stats, not much marketing, and monetization that stops at paid subscriptions. If you're on WordPress and the YouTube republishing makes you sit up, it's an easy yes.

How does Castos handle hosting and publishing?
On Castos I count 8 of the 9 hosting features I track, most of the list.
Castos gives me truly unlimited hosting, no caps on storage, episodes, or bandwidth. I can upload as much as I want, at any length, without watching a meter or worrying about overage charges.
I can schedule episodes ahead of time and have them publish automatically at the date and time I set, which is how I prefer to work.
There's a built-in, SEO-optimized podcast website where listeners can browse and play episodes directly, one less thing I'd have to build elsewhere.
I can connect my own custom domain to that website for a more professional look.
Multi-show management is here too, so I can run several podcasts from one account, which is exactly what I need when I'm a network or juggling more than one show.
Private and unlisted episodes are supported, which I'd use for premium content, internal podcasts, or subscriber-only drops.
Team collaboration is built in with role-based permissions, so I can hand teammates the right level of access, from full admin down to analytics-only.
Where does Castos distribute your podcast?
On Castos I count 6 of the 9 distribution features I track, most of the list.
Castos pushes my podcast out to all the major listening apps, Apple Podcasts, Spotify, Amazon Music, Google Podcasts, and the rest. Once I publish an episode, it shows up across every connected directory on its own.
YouTube distribution is covered, which I care about more every year as video podcasting grows. My episodes can land on YouTube automatically and reach a whole separate audience.
I get a standard RSS feed generated automatically, so I keep full control of distribution and can add any other platform by hand.
Moving in from another host is painless, the one-click import tool brings over my episodes, metadata, and usually my download history.
Audio-to-video conversion is built in, turning my audio episodes into video for the likes of YouTube without extra software.

What marketing and growth tools does Castos offer?
On Castos I count 5 of the 11 marketing & growth features I track.
Marketing and growth is where Castos actually earns its place for me.
The clip generator is one of the tools I reach for most: it turns episodes into audiogram-style clips, waveform, captions, my branding, and short-form clips like these are about the most effective way I've found to promote a show on Instagram, TikTok, X, and LinkedIn.
The embeddable player is fully customizable, I can match it to my brand colors and drop it on any site or blog so visitors listen right there.
Episode chapters and markers let listeners jump around within an episode, which I always appreciate as a listener myself.
Automatic transcription turns my audio into text, better accessibility, something for search engines to index, and a head start on show notes.
There's a layer of AI-powered features too, which I use to create content faster and tune it for discovery.

What analytics does Castos provide?
On Castos I count 7 of the 15 analytics features I track.
Castos's analytics aren't IAB-compliant. I still find the data useful for spotting trends, but some advertisers will specifically ask for compliant numbers.
Download tracking is the baseline I always start with, how many times each episode was pulled, and how that trends over time.
Episode comparison lets me line shows up side by side to see which topics, formats, or release times pull the most.
I can see which apps my listeners use, Apple Podcasts, Spotify, Overcast, and so on, from the audience-by-platform breakdown.
Device analytics tell me whether people listen on mobile, desktop, smart speakers, or watches, which quietly shapes how I think about length and format.
Country-level data shows me my global reach and helps me tailor content or promotion to specific regions.
It goes down to city and region level too, so I know exactly where my most engaged listeners are.
Unique-listener tracking goes past raw downloads to the number of actual people tuning in, a far more honest read on audience size in my experience.
Average listening time tells me how long people stick around, which helps me settle on the right episode length.
Can you make money with Castos?
On Castos I count 1 of the 6 monetization features I track.
Castos gives me a few real ways to make money from a show.
Dynamic ad insertion (DAI) lets me drop pre-roll, mid-roll, and post-roll ads in programmatically. Unlike baked-in spots, I can swap or pull these anytime, so even my back catalog keeps earning, and I can target specific episodes or the whole library.
Paid subscriptions and premium content let me offer exclusive episodes, early access, or bonus content to paying listeners. That gives me recurring revenue that doesn't live and die by download numbers or ad rates.
Crowdfunding hooks into the likes of Patreon, so my most dedicated listeners can chip in through recurring donations or one-off tips.

I couldn't tick any of the 5 ai features features I track on Castos.
AI has become part of how I work, and Castos folds in tools to speed up content creation.
AI transcription turns my audio into text and labels each speaker automatically, so the transcript is immediately usable as show notes, a blog post, or accessibility content.
AI-generated titles and descriptions read my episode and draft SEO-friendly copy, which saves me time and tends to sharpen my keywords.
AI social posts give me ready-to-publish copy for each episode across X, LinkedIn, Instagram, and the rest.
