RevenueCat is the standard subscription infrastructure for mobile apps, in-app purchases, paywalls, funnels, and cross-platform subscription analytics. Dunlo is for web SaaS founders running Stripe Billing who need failed payment recovery, not app-store purchase infrastructure.
Conversion path
Use the benchmark first. It gives visitors a useful estimate before signup and keeps the next step lighter than connecting an account immediately.
Dunlo fit
You sell a web SaaS subscription through Stripe.
You need direct customer emails after a Stripe invoice fails.
You want founder escalation when an important Stripe customer is at risk.
Comparison
This comparison is based on public product pages and documentation. Dunlo details reflect the current beta offer.
| Criteria | RevenueCat | Dunlo beta |
|---|---|---|
| Primary platform | Mobile and app subscriptions, with SDKs and infrastructure for in-app purchases plus integrated web billing. | Web SaaS subscriptions running on Stripe. |
| In-app purchases | Yes. RevenueCat simplifies implementation and maintenance of in-app purchases across platforms. | No. Dunlo does not manage app-store purchases. |
| Subscription analytics | Yes. RevenueCat includes dashboards, reporting, events, cohorts, and lifecycle integrations. | Recovery analytics only: at-risk payments, recovered revenue, and escalation context. |
| Failed payment recovery | RevenueCat supports lifecycle and retention tools for app subscriptions, but app-store billing recovery is constrained by Apple and Google. | Built for Stripe failed invoices where Dunlo can send email sequences and surface founder follow-up. |
| Failure-code-specific emails | Not the core model. RevenueCat is subscription infrastructure rather than Stripe decline-code dunning. | Yes. Dunlo changes copy and timing based on the Stripe failure reason. |
| Pricing entry | Free up to $2,500 in monthly tracked revenue, then 1% of tracked revenue on Pro. | Free during beta. Planned tiers start at $19/mo for Stripe recovery. |
Public proof
Dunlo is still in beta, so the page shows what can be verified today: assumptions, recovery mechanics, and a clear policy for publishing customer proof.
The public calculator shows MRR bands, estimated failed MRR, and recovery assumptions without asking for an email first.
Dunlo is built around Stripe decline reasons, timed emails, hosted update links, and founder escalation.
Customer screenshots, recovery stories, and beta metrics stay private until the sample is useful and the customer signs off.
Free beta
Use RevenueCat if your subscription revenue runs through iOS, Android, or app-store purchase infrastructure. Use Dunlo if your SaaS is web-first on Stripe and you need recovery emails, visibility, and founder escalation when invoices fail.
