Tunno
A native macOS app for localhost tunneling, request inspection, and webhook replay.
Product memo
Targets macOS developers debugging webhooks and local servers, frustrated by context-switching between separate CLIs and web tools. Its wedge is a unified, native macOS experience that bundles localhost tunneling, request inspection, and webhook replay. This integrated approach creates a sticky user experience, making it hard to revert to a multi-tool setup.
For who
macOS developers debugging webhooks and local servers
Solves what
Integrated localhost tunneling, request inspection, and webhook replay in one native app
- Native macOS app
- Real-time request inspection
- One-click webhook replay
In their own words
A tunnel that
One native Mac app. Public URL for your localhost, every request visible, every webhook replayable.

Pricing Strategy
Employs a freemium model with a generous free tier, offering a clear value-based upgrade path to a Pro subscription.
- • A free Hobby tier offers core tunneling and inspection to drive initial adoption and allow basic debugging.
- • The $12.99/month Pro tier unlocks advanced features like breakpoints, mocking, and higher usage limits for power users.
- • Bundles essential developer tools into a single native app, justifying the Pro upgrade by eliminating tool sprawl and context switching.

Builder Lesson
Bundle distinct but complementary developer workflows into a single, opinionated native app to create high switching costs.
Full Reasoning
Wins by deeply integrating three common developer tasks—tunneling, inspection, and replay—into one native macOS app, directly attacking the context-switching pain point. The asymmetric bet is the opinionated bundling and native experience, which incumbents (often CLI-based or separate tools) cannot easily replicate without cannibalizing their existing offerings. Builders should consider consolidating adjacent workflows for specific ICPs to create sticky, indispensable tools, as demonstrated by the clear value proposition of a single app over disparate utilities.
About Tunno Expand
Tunno provides a streamlined solution for macOS developers who regularly debug webhooks and local servers. Instead of juggling multiple command-line interfaces and browser-based tools, it integrates localhost tunneling, request inspection, and webhook replay into a single, intuitive native application.
This consolidation eliminates the friction of context-switching, allowing developers to focus more on their code and less on their tooling. The app's design prioritizes a seamless user experience, offering features like breakpoints and request mocking within the same environment.
Tunno’s approach targets a specific pain point for a focused audience, delivering a cohesive debugging experience that standalone tools often fail to provide.
