Engineered for Absolute Discipline.

Zero willpower required. The software takes the burden of self-control completely off your shoulders.

Zero Customization. No Exceptions.

No tedious blocklists. No customizable whitelists. No pause button.
It ruthlessly terminates everything except your raw work tools. Need to check social media or watch videos? Get off your Mac and use your phone.

Deep-System Network Enforcement

Enforces focus boundaries directly at the deepest system layer using native macOS Packet Filter (pf).
We do not use unstable Kernel Extensions (Kexts) or easily bypassed /etc/hosts modifications. Commercial VPNs, custom DNS profiles, and browser secure-proxy bypass attempts are instantly neutralized locally.

Immutable Session Clock

The lockdown operates completely detached from user-controllable settings.
Changing system time, altering timezones, or performing an offline reboot is entirely futile. The atomic countdown will not yield until your time is served.

Encrypted Edge Filtering

Instantly neutralizes YouTube, Reddit, X (Twitter), TikTok, Adult Content (18+), Gambling, and all Social Media.
Drops distracting packets, trackers, and ad telemetry at the root before they ever hit your screen.

Developer & Workspace Friendly

Engineered for real engineering workflows.
Localhost, Docker containers, Tailscale, and SSH remain 100% accessible.
You can push code, access databases, and build local projects with zero interruption.

bash
$ ssh user@192.168.1.10
> Connected to Local Server (Authorized)

$ ping youtube.com
> Request timeout for icmp_seq 0 (Dropped)

Zero-Trace Privacy Engine

100% local data sovereignty. We do not inspect payloads, log traffic, or store your browsing history. What happens on your Mac, stays on your Mac.

The "Walk of Shame" Emergency Unlock

We don't hold your hardware hostage, but we will hold your ego accountable.

Need to bail out of an active focus session early? You'll have to type a mathematically generated, humiliating confession.

  • No Copy-Pasting: Clipboard injection is strictly blocked.
  • No Drag & Drop: Triggers an immediate keystroke penalty.
  • No App Switching: Cursor leaves the window? The phrase resets immediately.

There is no back button. There is no terminal trick. You either build your future, or you type your surrender.

EMERGENCY UNLOCK

If you must end your focus session early, type the exact confirmation phrase below as a single continuous line (do not press Enter):

I used to bypass Screen Time and hosts files in under 30 seconds whenever dopamine craving hit. KillSwitch is the first tool on macOS I physically couldn't trick. It paid for itself on my first sprint.

Writing technical manuscripts requires 4-5 hours of sustained mental RAM. One click turns my MacBook into an offline typewriter. Docker and research work, but YouTube and Twitter simply don't exist.

The Walk of Shame is ruthless psychological design. I only attempted an Emergency Unlock once - the humiliation of typing that phrase cured my urge to check metrics for the rest of the week.

Frequently Asked Questions

Everything you need to know about system safety, privacy, and licensing.

Can I just change my Mac's clock or timezone to bypass the lockdown?
No. KillSwitch does not rely on your user-configurable system clock. The core engine uses a proprietary continuous tick-counter combined with a secure, tamper-proof network time sync. Fast-forwarding your clock will not speed up the session, and turning back time while offline will instantly invalidate your active session to prevent cheating.
What if I Force Quit the app, delete it, or turn off 'App Background Activity'?
Your internet will be permanently cut off. KillSwitch enforces boundaries at the deepest system layer, entirely independent of the UI application. If you attempt to sabotage the background processes, delete the app, or revoke background permissions during an active lockdown, our anti-tampering watchdog will intentionally trigger a 'Kamikaze Mode'. This locks your network firewall in a permanent drop-all state. Rebooting won't save you. The only way to get your internet back is to open the app, face the consequences, and manually type out the humiliating "Walk of Shame" confession.
What exactly does KillSwitch block? Can I see a list?
KillSwitch automatically neutralizes all major social networks (X/Twitter, Reddit, Instagram, Facebook, TikTok, Threads), video streaming entertainment (YouTube, Netflix, Twitch), adult content (18+), gambling websites, and intrusive advertising telemetry.

Meanwhile, your work tooling remains 100% accessible: GitHub, GitLab, StackOverflow, documentation portals, package registries (npm, cargo, pip), Localhost, Docker subnets, Tailscale, and LAN environments function seamlessly.
Can I whitelist YouTube just for 'educational' tutorials or background Lo-Fi music?
No. KillSwitch is uncompromising by design. The moment you whitelist YouTube "for music," your brain will rationalise clicking recommendations 15 minutes later. If you need music during deep work, use local audio files, offline Spotify playlists, or play it from your phone across the room. Your Mac workstation is for shipping output, not consumption.
What if I'm at an airport or hotel and need to log into public Wi-Fi?
We've engineered a secure micro-tunnel specifically for this scenario. The Apple Captive Portal authentication domain is safely whitelisted. You can successfully authenticate to public Wi-Fi networks without breaking your active lockdown session.
Is KillSwitch a VPN or proxy service? Does it monitor my traffic?
No, absolutely not. KillSwitch is a local-first digital wellbeing utility. All focus rules are enforced natively on your Mac using low-level OS firewall APIs. We do not route, inspect, log, or sell your internet traffic.
How does the device limit work? Can I use it if I buy a new Mac?
Licenses are cryptographically bound to your Mac's unique Hardware UUID. The Solo plan covers 1 Mac, and the Duo plan covers 2 Macs concurrently. If you purchase a new Mac, you can instantly unlink your old device directly within the KillSwitch app before migrating, which frees up your license slot for the new machine.
Which macOS versions and architectures are supported?
KillSwitch is compiled natively as a Universal 2 Binary. The current version supports macOS 12.0 and later. It runs at native hardware execution speed across all Apple Silicon (M-Series) processors and legacy Intel-based Macs with zero translation overhead or Rosetta emulation required.
How does the "Perpetual License" and macOS compatibility work?
We use a Perpetual Fallback License model (similar to JetBrains or Sketch). Your purchase grants you a lifetime license to keep and use the version of KillSwitch you purchased forever, on the macOS versions it was originally certified for.

Because KillSwitch interacts with deep OS network internals, it is "OS-Pinned" for your safety. For example, if you buy the app while on macOS 14, you can use it on macOS 14 forever. However, if Apple later releases macOS 16 with a completely different kernel architecture, the old app will actively block its own execution to prevent crashing your Mac.

Your purchase includes 1 full year of free software updates and new macOS compatibility patches. After that year, if you upgrade your Mac to a brand-new OS version, you will need to pay a discounted renewal fee to download the safely compatible version of KillSwitch. If you don't update your OS, you never have to pay again.
What happens if I reboot or restart my Mac during a session?
Nothing changes. The lockdown state is persistent and anchored independently of controllable OS settings. When your Mac boots back up, background safety protocols immediately re-enforce the network boundaries until your session timer naturally expires.
Will this break Localhost, Docker, or my company VPN/LAN?
No. KillSwitch is specifically engineered for professionals. We safely whitelist internal subnets (Localhost, Docker containers, Tailscale mesh networks, and local LAN environments). You can push code, access databases, and build local projects with zero interruption.
What is your exact refund policy?
We offer a 14-Day Performance & Compatibility Guarantee. If KillSwitch encounters a verified technical defect or operating system incompatibility on your supported Mac that our engineering support cannot resolve within 48 business hours, you will receive a full 100% refund.

Simply email help@prodigysolutions.tech with your order receipt. Refunds are processed through our Merchant of Record and return to your original payment method within 5–10 business days. Upon refund, your license key is permanently deactivated.
