How we picked
Every one of these podcast hosting platforms is scored by the same 8 criteria (scorecard v2). Each criterion gives 0 to 100 from the vendor's published data; the total is the weighted average. A criterion without verified data is left out and the other weights are re-normalised. A tool with under 60% of the weight covered is listed as not ranked, and so is a tool with no verified price and fewer than 2 verified features (“needs a verified price”); each score shows how many criteria it is based on. The core criteria are the same in every category; the category criteria are specific to podcast hosting platforms. Nobody gets custom weights, including our own products.
| Criterion | Weight | Type | What we measure |
|---|---|---|---|
| Entry price | 25% | Core | Price per month of the cheapest paid plan, against the prices of other podcast hosting platforms on the same billing basis (monthly-billed prices against monthly, annual-billed against annual).Log scale. Billed monthly: $7/month or less = 100, $29 or more = 0. Only billed annually: $6.38/month or less = 100, $25.54 or more = 0. Only free plans = 100. Usage-priced and one-time plans are not scored. |
| Free plan or trial | 15% | Core | Whether you can use the tool before paying: a free plan, or failing that a free trial, as shown on the vendor's pricing page.Free plan = 100. No free plan but a free trial = 60. The pricing page lists plans but shows neither = 0. No plans read = not scored. |
| Pricing transparency | 10% | Core | How much of the pricing is public: the share of plans with a published price ("contact sales" counts against), and whether there are at least 3 published tiers.80 x (plans with a public price / plans listed) + 20 x (public plans, up to 3) / 3. No plans read = not scored. |
| Verified features | 15% | Core | How many of the 10 features we track for this category the vendor's own pages verifiably show (one-click distribution to podcast apps, listener analytics, iab-certified analytics, monetisation (ads or listener support), dynamic ad insertion, transcripts, video podcasts, private podcasts, podcast website, team access). This counts verified features only: a tool that documents less scores lower here, and only here.Linear: verified features / 5 (half the tracked list) x 100, capped at 100. No tracked feature verified = not scored. |
| API, integrations and export | 10% | Core | Whether a public API exists, how many integrations the vendor states, and whether the vendor documents a way to export your data.Average of the parts with data: public API yes = 100, no = 0; integrations on a log scale (30 or more = 100); a documented data export = 100. None verified = not scored. |
| Shows per plan | 10% | Category | Podcasts included on the cheapest paid plan that states a limit.Log scale: 10 or more (or unlimited) = 100. No stated limit = not scored. |
| Upload allowance | 10% | Category | Upload hours per month included on the cheapest paid plan that states a limit.Linear scale: 10 or more (or unlimited) = 100. No stated limit = not scored. |
| Cost per user (team of 3) | 5% | Category | Monthly price per user for a team of 3, on the cheapest paid plan that is priced per seat or states room for at least 3 users.Log scale: $6.16 per user or less = 100, $24.65 or more = 0. Plans that do not state a user limit are not used. No such plan = not scored. |
