Radio Silence Alternative for Mac: NetBlocker vs Radio Silence
Looking for a Radio Silence alternative? Compare NetBlocker’s app-centred blocking with Radio Silence’s system-wide connection view, pricing, compatibility, and process visibility.
Two quiet workflows with different centres
Both products let you choose apps to block without approving every connection. NetBlocker starts with a deliberate app list and keeps each app’s associated processes together. Radio Silence combines its blocklist with a separate view of current connections across the Mac. Neither layout is inherently stronger; they answer different questions.
This comparison is written by NetBlocker’s developer, not an independent reviewer. Competitor details were checked against the official Radio Silence website on 20 September 2026. It is a feature comparison, not a performance or reliability benchmark.
The practical differences
| Consideration | NetBlocker | Radio Silence |
|---|---|---|
| Price | €4.99 lifetime license | US$9 |
| Refund period | 30-day money-back guarantee | 30-day money-back guarantee |
| Mac support | Apple silicon; macOS 13+ | Intel and Apple silicon; macOS 10.15+ |
| Workflow | Drag an app into an app-centred blocking list | Quiet app blocklist plus a system-wide monitor |
| Process visibility | Related components grouped under each blocked app | Current helpers, XPC services, and daemons in a whole-Mac connection view |
| Designed for | Keeping selected apps offline with minimal configuration | Silent blocking combined with system-wide connection visibility |

Choose by the view you want every day
Consider NetBlocker if you have a supported Apple silicon Mac and want the blocked app, protection status, and associated processes together in one focused interface. It costs €4.99 and avoids turning simple app selection into a connection-analysis task.
Consider Radio Silence when a live, system-wide view of current connections is part of what you want to inspect, or when you need Intel support or an older supported macOS release. That extra view is a different workflow, not evidence that either product blocks more effectively.
Both tools address helper processes. We have not established that one detects or blocks more helpers than the other, nor that one uses less CPU or battery.
Pricing, trial, refunds, and offline use
NetBlocker costs €4.99 for a lifetime license, includes a full seven-day trial without a card, and provides a 30-day money-back guarantee after purchase. A paid license needs periodic online validation and has a 14-day offline allowance; protection resumes after successful validation.
Radio Silence lists a free trial, a US$9 purchase price, and a 30-day money-back guarantee. Its public feature page does not describe periodic license validation, so check its current terms or ask its developer if long-term offline use is important to you.
Test the workflow that matches your goal
Save your work and test a non-critical app first. Check that protection is active, reopen the target app, and test a new online request. Avoid stacking multiple filters while comparing because that makes it hard to tell which product caused a result.
Our step-by-step blocking guide explains installation, checking related processes, what a saved rule tells you, and what it does not.
