# Little Snitch vs Radio Silence

Published January 1, 2026 · Updated August 10, 2026

Little Snitch and Radio Silence are both firewall on a Mac, so the pick depends on workflow. Pay for Little Snitch when the monitor and the narrow rule are the job. Pay $9 for Radio Silence when the job is a quiet list of apps that must stay offline. As of October 2026, both install with brew install --cask little-snitch and brew install --cask radio-silence.

Little Snitch 6.5 is the tool whose own page documents the map, the twelve-month chart, Silent Mode, and a rule for a server, domain, port, or protocol, at 59 € for a single licence. Radio Silence 3.4 is the tool whose own page documents a $9 whole-app block, no pop-ups, and a live connection list. Neither score is a measured test.

## Features

- **Price.** Radio Silence is the smaller listed price. Little Snitch's order page is in euros and lists several licences, not a dollar equivalent.
- **Rule scope.** Little Snitch documents a narrow target. Radio Silence documents the whole app.
- **Prompts.** Little Snitch asks, with Silent Mode as the quiet option. Radio Silence does not ask.
- **Monitor depth.** Little Snitch's page states the long chart and the map. Radio Silence's page states a live list.
- **Blocklists and profiles.** Those two features are on the Little Snitch product page.
- **Current build and Mac support.** Both vendors name a current build and a recent macOS line. The version numbers are not comparable as a quality score.

## FAQ

### What does Little Snitch cost, and in which currency?

Objective Development prices Little Snitch in euros: single 59 €, family 115 €, multi 5× 239 €, multi 10× 419 €. The Snitch Bundle single licence is 61.25 €, and 63.49 € is shown as the original price. Prices are listed in euros only.

### What does Radio Silence cost?

Radio Silence is $9, with a free trial and a 30-day money-back guarantee.

### Which versions were current on 2026-10-14?

Little Snitch 6.5, build 7303, dated 8 September 2026, for macOS 27 Golden Gate plus Tahoe, Sequoia and Sonoma. Radio Silence 3.4 for macOS 10.15 and newer. The Radio Silence download page does not print a calendar date for 3.4.

### Does Radio Silence show a map and a year of history?

Radio Silence has a real-time network monitor, with no map or twelve-month chart. Little Snitch has both.

### Can I run both at once?

Each app is a network filter, and two filters at once make it hard to tell which one blocked a connection. Use one, confirm it is the only network filter, and then judge the alerts or the block list on its own.
