We build native macOS applications that put information and power back in your hands. Our current focus is security and privacy — giving you visibility into what your computer is actually doing on the network, over the air, across your processes, and inside your configuration. But we’re also building tools for social networking, financial planning, and making everyday consumption visible.
The thread that connects all of it: software that serves you, not a platform. No subscriptions, no telemetry, no cloud dependencies. Every app is built with Swift and SwiftUI, ships as a single DMG, and respects your privacy by design.
Most software asks you to trust a vendor: hand over your data, accept their defaults, hope they’re acting in your interest. We think that model is backwards.
Our tools are observe-first — they show you what’s happening and let you decide what to do about it. They don’t block, filter, or phone home. They don’t require accounts, subscriptions, or internet access. They run on your machine and answer to you.
We’re releasing Harden, a native macOS tool that audits your Mac’s security configuration against 52 best-practice checks and helps you fix what it finds — no Terminal required.
The gap it fills Your Mac has dozens of security settings spread across System Settings, command-line tools, and kernel parameters. Guides exist for hardening them, but they’re aimed at sysadmins and expect you to run commands like defaults read com.apple.alf globalstate and interpret the output. Harden does all of that for you and presents the results in plain language with one-click fixes.

Introducing Spektra
We’re releasing Spektra, a native macOS spectrum analyzer that turns an inexpensive RTL-SDR USB dongle into a full-featured radio exploration tool. See, identify, and listen to signals from 24 MHz to 1.7 GHz.
The gap it fills SDR software on the Mac has historically meant running GNURadio in a Linux VM, or using CubicSDR (which hasn’t been updated in years). Spektra is a native Swift/SwiftUI app that bridges directly to librtlsdr — no VMs, no Qt, no X11. Plug in a dongle and you’re looking at the spectrum.

Introducing Vigil
We’re releasing Vigil, a native macOS system monitor that watches your processes and file activity, learns what “normal” looks like, and flags anything unusual. It’s a behavioral antivirus — it doesn’t block, it observes and reports.
The gap it fills Activity Monitor tells you CPU percentage and memory usage. But it can’t tell you that a process is doing ten times its normal disk I/O, that an unknown process appeared with no executable path, or that an AI coding tool just touched files outside its expected scope. Vigil fills that gap with behavioral baselines and heuristic analysis.

Introducing Survey
We’re releasing Survey, a native macOS tool that shows you what your computer reveals about itself through Bluetooth, WiFi, and location services.
What it does Your Mac is constantly broadcasting and receiving signals. Bluetooth beacons from nearby trackers and smart glasses, WiFi probes from networks around you, location data leaking through permissions you may have forgotten about. Survey makes all of this visible.
It has three tabs:
Bluetooth — scans for nearby BLE devices using a database of ~130 device signatures. Categorizes what it finds (trackers, glasses, wearables) and assigns threat levels. High-threat devices trigger desktop notifications. WiFi — grades your current network’s security (A-F), fingerprints the access point type, scans nearby networks, and audits your saved networks against ~90 known suspicious SSIDs. Location — computes a privacy exposure score based on your permissions, Bluetooth state, and network security. Maps your location history and links to macOS privacy settings. Why not just block everything? Survey isn’t a blocker. It’s a visibility tool. You can’t make good privacy decisions without first understanding what’s happening. Survey shows you the landscape — which devices are nearby, how secure your network is, what your location permissions expose — and then you decide what to do about it.

Introducing Tapped
We’re releasing Tapped, a native macOS network dashboard that shows you exactly where your computer is talking — which apps, which destinations, how much data, and for how long.
The gap it fills Most people have no idea what their Mac is doing on the network. You could fire up Wireshark, but that’s a firehose of raw packets aimed at network engineers. You could check Activity Monitor, but its network tab is minimal. Tapped sits between the two: enough depth to be useful, enough clarity to be approachable.

Introducing the Subversive Software Webring
What Is a Webring? Webrings were one of the earliest forms of community building on the internet. In the 1990s, before search engines dominated discovery, webrings linked together sites with shared interests. You’d visit a site, click “next” or “previous,” and travel through a curated ring of related pages.
The original webrings died off as Google became the default way to find things online. But something was lost in the process: the serendipity of stumbling on a small, personal site that someone poured their energy into. The web became centralized, discoverable only through algorithms that favor engagement over substance.

Welcome to Subversive Software
Why Subversive Software? The word “subversive” might sound aggressive or destructive, but our mission is anything but. We’re subversive in the most hopeful sense: we’re working to undermine systems that exploit people and replace them with tools that empower individuals.
The Problem Modern software often treats users as products. Our data is harvested, our attention is monetized, and our privacy is treated as negotiable. We’re tracked across websites, our behaviors are analyzed, and our information is sold to the highest bidder.
