What is Castos?

Castos is a podcast hosting platform built for creators who want WordPress integration, private podcasting, and video episode hosting. It offers unlimited podcasts and episodes on every plan, with automatic distribution to major directories. Plans start at $19/month with a 14-day free trial, and the WordPress plugin makes it a natural fit for WordPress-powered podcast sites.

Castos pricing breakdown -- what each plan actually includes

Castos structures pricing around download caps, private subscriber limits, and feature access. The Essentials plan at $19/month ($190/year) includes unlimited podcasts and episodes, up to 100 private subscribers, 20,000 monthly downloads, and 10 episode transcription credits per month. The Growth plan at $49/month ($490/year) expands to 250 private subscribers, 75,000 monthly downloads, YouTube republishing, Headliner audiogram integration, and 25 transcription credits.

The Pro plan at $99/month ($990/year) is where Castos's full feature set unlocks: video file hosting, 500 private subscribers, 200,000 monthly downloads, advanced analytics, and 100 transcription credits. The Premium plan at $499/month adds custom contracts, SSO, and a dedicated account manager for large organizations.

The cost that catches people off guard: private subscriber overages. Once you pass 500 private subscribers on the Pro plan, each additional 500 subscribers costs $50/month. If you are building a private podcast for a course or membership with growing enrollment, this overage cost can add up quickly. Also, video hosting is Pro-only, so if video is the reason you are looking at Castos, the real starting price is $99/month, not $19/month.

Compared to Buzzsprout ($12/month for 3 hours), Castos's Essentials plan at $19/month is more expensive but includes unlimited episodes and private podcasting. Transistor ($19/month) matches the price and includes unlimited downloads, but does not offer video hosting or WordPress integration. Podbean ($14/month for unlimited) is cheaper but lacks Castos's private podcast features.

Essentials: $19/mo ($190/year (~$15.83/mo))
Growth: $49/mo ($490/year (~$40.83/mo))
Pro: $99/mo ($990/year (~$82.50/mo))
Premium: $499/mo (Custom contracts available)

What Castos actually does (and what it doesn't)

Castos is the best podcast host for WordPress users and one of the few platforms that takes private podcasting seriously. The WordPress plugin creates a genuinely seamless publishing workflow, and private podcast feeds open up use cases (courses, memberships, internal communications) that most hosts do not support at all. The downside is that Castos is not the cheapest option, the Essentials plan has tight download caps (20,000/month), and the video hosting that makes Castos special requires the Pro plan at $99/month. If you are not using WordPress and do not need private feeds, Buzzsprout or Transistor offer comparable hosting at similar or lower prices with less complexity.

Quick verdict

Best when: You run a WordPress site and want your podcast publishing workflow integrated directly into WordPress, or if you...

Worth it if: Essentials ($19/month) works if you are a solo podcaster with a WordPress site and fewer than 20,000 downloads...

Think twice if: Essentials caps at 20,000 downloads per month, Growth at 75,000, and Pro at 200,000

Castos is best for

You run a WordPress site and want your podcast publishing workflow integrated directly into WordPress, or if you need private podcast feeds for courses, memberships, or internal team communications. Skip it if you do not use WordPress, do not need private feeds, and just want straightforward public podcast hosting. The sweet spot is WordPress-based creators, educators, and businesses using podcasts for gated content.

Why Castos stands out

WordPress integration, private podcasting, and video episode hosting. The Seriously Simple Podcasting WordPress plugin creates episodes automatically when you publish in Castos, syncing titles, descriptions, and audio without duplicating work. Private podcast feeds with subscriber management are more developed than any competitor. vs. Buzzsprout: built-in WordPress workflow and private feeds that Buzzsprout does not offer. vs. Transistor: video hosting and deeper WordPress integration, though Transistor has unlimited downloads.

Is Castos worth the price?

Essentials ($19/month) works if you are a solo podcaster with a WordPress site and fewer than 20,000 downloads per month. Growth ($49/month) if you need YouTube republishing or have a growing private audience. Pro ($99/month) only if you need video hosting or have 200,000+ downloads. Start with the 14-day free trial and test the WordPress plugin with your actual site before committing.

Castos features

WordPress Integration via Seriously Simple Podcasting

Castos's Seriously Simple Podcasting plugin is the deepest WordPress integration in podcast hosting. Install the free plugin, connect your Castos account, and every episode you upload in Castos automatically generates a WordPress post with the embedded audio player, episode title, description, and metadata. You can also publish directly from WordPress, with the plugin handling the upload to Castos in the background. The limitation is that the plugin requires WordPress.org (self-hosted). It does not work with WordPress.com's hosted plans unless you are on the Business tier or higher. Setup takes 10-15 minutes, and occasional plugin updates can temporarily break the sync. Keep both the plugin and WordPress core updated to avoid issues.

Private Podcast Feeds and Subscriber Management

Castos lets you create private podcast feeds that are only accessible to approved subscribers. Each subscriber gets a unique RSS feed URL that works in any standard podcast app (Apple Podcasts, Overcast, Pocket Casts). You can manage subscribers, track who is listening, and revoke access individually. This makes Castos a natural fit for online courses, paid memberships, corporate training, and client-only content. The constraint is subscriber limits per plan: 100 on Essentials, 250 on Growth, and 500 on Pro. Exceeding 500 on Pro costs $50 per additional 500 subscribers per month. If your private podcast serves a large audience (a course with 1,000+ students), the overage costs add up. Budget for growth when choosing your plan.

YouTube Republishing and Video Hosting

On the Growth plan, Castos can automatically republish your audio episodes to YouTube by converting them into video files with your podcast artwork. This gives you YouTube presence without manually creating videos. On the Pro plan, you get native video file hosting, meaning you can upload actual video episodes and distribute them alongside your audio feed. The YouTube republishing feature is useful for SEO and discoverability, but the auto-generated videos (static image with audio) are not engaging enough to build a YouTube audience on their own. For genuine video podcasting, you need the Pro plan at $99/month. If you are producing video content, also consider whether Podbean or Spotify for Podcasters might meet your video needs at a lower price.

Automatic Transcriptions and Content Repurposing

Castos provides AI-powered transcription credits on every plan (10 on Essentials, 25 on Growth, 100 on Pro). Transcripts are generated automatically after you publish an episode and can be used for show notes, blog posts, accessibility compliance, and SEO. The transcripts are also displayed on your podcast website for search engine indexing. Accuracy is generally good for clear English audio but struggles with heavy accents, multiple speakers talking over each other, and technical jargon. The credit system means you need to plan your transcription budget, especially on the Essentials plan where 10 credits covers only 10 episodes per month. If you publish more frequently, you will need a third-party service like Otter.ai or Rev for the overflow.

Strengths

The strengths that matter most once you start using Castos daily.

Best-in-class WordPress integration

Castos's Seriously Simple Podcasting plugin turns WordPress into a full podcast management system. When you upload an episode in Castos, the plugin automatically creates a podcast post in WordPress with the audio player, title, description, and metadata. You can manage everything from either the Castos dashboard or your WordPress admin. For podcasters already running a WordPress site, this eliminates the friction of managing content in two separate platforms.

Private podcast feeds for courses, memberships, and teams

Castos supports private podcast feeds where you control who can listen. You can create gated content for paid memberships, online courses, employee onboarding, or client-only updates. Subscribers get a unique RSS feed that works in any podcast app. This is a feature most podcast hosts either do not offer or charge significantly more for. For educators and membership creators, it is a genuine differentiator.

Unlimited podcasts and episodes on every plan

All Castos plans let you create unlimited shows and publish unlimited episodes. There are no caps on the number of podcasts you can host or episodes you can publish. This is useful for creators who produce multiple shows, seasonal content, or want to experiment with different formats without worrying about hitting a limit.

Video podcast hosting on the Pro plan

Castos's Pro plan supports video episode hosting, letting you upload video files alongside audio and deliver them to listeners who prefer video. Combined with the YouTube republishing feature on the Growth plan, Castos covers both audio and video distribution. For podcasters making the jump to video, having hosting and distribution in one platform simplifies the workflow.

One-on-one onboarding call included on every plan

Every Castos customer, regardless of plan, gets a one-on-one onboarding call with the Castos team. On Growth and above, they will also help you migrate from another host. This is unusually hands-on for a podcast host at the $19-$49/month price range. For podcasters switching from another platform or setting up their first show, the guided onboarding saves time and reduces setup errors.

Limitations

Check these before subscribing — these are the limitations most likely to affect your experience.

Download caps on every plan, including Pro

Essentials caps at 20,000 downloads per month, Growth at 75,000, and Pro at 200,000. If you exceed the cap, you will need to upgrade or pay overages. Transistor and RSS.com offer unlimited downloads on their plans, which makes Castos a more expensive choice for podcasts with large back catalogs or growing audiences. Calculate your current monthly downloads before choosing a plan.

Video hosting requires the $99/month Pro plan

If video podcasting is why you are considering Castos, the real starting price is $99/month, not $19/month. Video file hosting is locked to the Pro tier. The Growth plan does include YouTube republishing (converting audio to video), but that is not the same as hosting native video episodes. For podcasters on a budget who want video, Podbean includes video support on cheaper plans.

Private subscriber overages can get expensive

The Pro plan caps private subscribers at 500. Each additional 500 subscribers costs $50/month. If you are running a course or membership podcast that grows past 500 subscribers, costs escalate quickly. At 2,000 private subscribers, you would be paying $99 base plus $150 in overages, totaling $249/month. Plan for growth when budgeting.

No free plan available

Unlike RSS.com (free forever), Buzzsprout (free tier with 2 hours/month), and RedCircle (free tier with unlimited hosting), Castos has no free plan. The 14-day free trial is generous enough to test the platform, but there is no way to host a podcast on Castos indefinitely without paying. For hobbyist podcasters testing the waters, this is a barrier.

Transcription credits are limited per plan

Essentials includes 10 transcription credits per month, Growth includes 25, and Pro includes 100. If you publish more episodes than your credit allotment, you will need to use a third-party transcription service or pay for additional credits. Podcasters publishing daily or running multiple shows will burn through credits quickly on the lower plans.

Setup, WordPress integration, and migration

Getting started with Castos takes about 15-20 minutes. You create an account, set up your show, upload artwork, and publish your first episode. Distribution to Apple Podcasts, Spotify, Amazon Music, and other directories is handled automatically through your RSS feed. If you are using WordPress, installing the Seriously Simple Podcasting plugin adds another 5-10 minutes but streamlines all future publishing.

The learning curve is moderate. The Castos dashboard itself is straightforward, but configuring the WordPress plugin, setting up private podcast feeds, and understanding the download/subscriber limits takes a bit more time. The one-on-one onboarding call is genuinely helpful here. Budget 2-3 publishing sessions to feel fully comfortable with the workflow.

For teams, Castos works well once configured. Multiple team members can access the dashboard, and the WordPress integration means your editors and producers can work within their familiar WordPress environment. Private podcast management includes subscriber tracking and feed management tools. On Growth and above, Castos handles migration from other hosts as part of onboarding.

Practical tip: if you are using WordPress, set up the Seriously Simple Podcasting plugin before uploading any episodes. This ensures every episode you publish in Castos automatically creates a corresponding WordPress post with the embedded player. Retrofitting the plugin after you have already published episodes adds unnecessary cleanup work.

Before you subscribe

Free trial and getting started with Castos

Before you subscribe to Castos, answer these questions. The WordPress integration and private podcasting features are compelling, but they are only valuable if they match your actual setup.

1

Confirm that you actually use WordPress. If your site runs on Squarespace, Wix, or another platform, Castos's biggest advantage (the WordPress plugin) does not apply to you. In that case, Buzzsprout or Transistor may be a better fit at a similar or lower price.

2

Calculate your monthly downloads and compare them to the plan caps. If you are consistently above 20,000 downloads per month, the Essentials plan will not work and you should budget for Growth ($49/month) from the start.

3

Determine whether you need private podcast feeds. If you are selling courses, running a membership, or creating internal content, Castos's private podcasting is a standout feature. If all your content is public, you are paying for a feature you will not use.

4

Check whether video hosting matters. If yes, be aware that it requires the Pro plan at $99/month. If video is a nice-to-have but not essential, the Growth plan's YouTube republishing may be sufficient at half the price.

5

Test Buzzsprout, Transistor, and Podbean alongside Castos during their free trials. Upload the same episode to each and compare the publishing workflow, analytics, and overall experience. The right host depends on your specific workflow, not feature lists.

Frequently asked questions about Castos

How much does Castos cost per month?

+

Castos offers Essentials at $19/month ($190/year), Growth at $49/month ($490/year), Pro at $99/month ($990/year), and Premium at $499/month for large organizations. All plans include unlimited podcasts and episodes. Download caps and feature access increase with each tier. Annual billing saves roughly two months.

Does Castos have a free plan or free trial?

+

There is no permanent free plan, but Castos offers a 14-day free trial on all tiers. The trial gives you full access to your chosen plan's features, including the WordPress plugin and private podcast tools. After 14 days, you must subscribe to continue hosting.

Who is Castos best for?

+

Castos is best for WordPress users who want seamless podcast publishing, educators and membership creators who need private podcast feeds, and podcasters who want video hosting on a single platform. It is less ideal for podcasters on a tight budget, those who do not use WordPress, or those who just need straightforward public hosting.

Castos vs Buzzsprout -- which is better?

+

Castos is better if you use WordPress, need private podcast feeds, or want video hosting. Buzzsprout is better if you want a lower starting price ($12/month), built-in monetization, AI features, and a more beginner-friendly experience without WordPress. Choose based on whether WordPress integration and private feeds matter to your workflow.

Does Castos integrate with WordPress?

+

Yes, and it is Castos's standout feature. The Seriously Simple Podcasting plugin syncs your Castos account with WordPress. When you upload an episode in Castos, the plugin automatically creates a podcast post in WordPress with the embedded player, title, description, and metadata. You can manage publishing from either platform.

Is Castos good for private podcasts and courses?

+

Yes. Castos supports private podcast feeds with subscriber management, making it one of the best options for gated audio content. You can create private feeds for courses, paid memberships, employee training, or client communications. Subscribers get a unique RSS feed that works in standard podcast apps. Private subscriber limits start at 100 on Essentials and go up to 500 on Pro.

Does Castos support video podcasting?

+

Yes, but only on the Pro plan ($99/month). Video file hosting lets you upload and distribute video episodes. The Growth plan ($49/month) includes YouTube republishing, which converts audio episodes into video format for YouTube, but this is not the same as native video hosting. If video is important, budget for the Pro plan.

Can teams collaborate on Castos?

+

Yes. Multiple team members can access the Castos dashboard, and the WordPress integration means editors and producers can work within WordPress. On Growth and above, Castos assists with migration from other hosts. The Premium plan adds dedicated account management. There are no granular role-based permissions on the self-serve plans.

Is Castos worth the money compared to cheaper hosts?

+

Castos is worth it if you specifically need WordPress integration, private podcast feeds, or video hosting. These features are genuinely better than what most competitors offer. If you do not need those features, Buzzsprout ($12/month) or RSS.com (free) provide solid hosting at a lower cost. Pay for Castos's specific strengths, not general hosting.

Can I cancel Castos and keep my podcast?

+

If you cancel, your podcast episodes are not immediately deleted. You can export your RSS feed and migrate to another host before your account is fully closed. Castos does not lock you into long-term contracts on the self-serve plans. The 14-day free trial lets you test the platform risk-free before paying.

Castos alternatives worth comparing

If Castos is not quite right for your podcast, these hosting platforms offer different approaches to pricing, features, and publishing workflows. The best alternative depends on whether you need cheaper hosting, different integrations, or a simpler setup.
