Blokhead a chrome/edge/firefox extension for blocking distracting websites
We’ve built tools that inspect model artifacts, generate SBOMs, and secure local AI workloads because we believe in low-level visibility. But there is a different kind of friction to manage: the human one. It lives in the browser tab where you meant to write code but opened Reddit instead. Most blockers fight this by demanding setup, tutorials, or account creation before they even touch a domain name. The result is usually a tool that sits dormant until someone remembers to configure it, and then gets disabled immediately when focus slips. Real discipline doesn’t require a dashboard; it requires immediate action.
Blokhead operates on the principle that blocking a site should not require a tutorial. You paste a domain or regex pattern, hit block, and keep going. That is the entire interaction. We built this extension specifically for Chrome, Edge, and Firefox users who want to stop bad tab habits without surveillance theater. The tool runs locally with no cloud dashboard, ensuring zero data collection on your browsing habits. It respects your time and intent, much like our lightweight CLI tools do for inspecting model artifacts.
The Friction Problem with Current Distraction Blockers
Most productivity extensions treat the user as a problem to be solved rather than a person trying to work. You are asked to create an account, watch a video about how to use the tool, and then configure it with a wizard that takes three steps just to block one site. By the time you finish, you’ve opened five new tabs looking for more information. Real discipline requires immediate action: pasting a domain and hitting block should be the entire interaction.
Users often disable blockers entirely because the initial configuration feels like work rather than a solution. If the tool takes longer to set up than it does to break the habit, it has already failed. We know this from watching how developers interact with our own CLI tools. When you run l-bom scan .\models\Llama-3.1-8B-Instruct-Q4_K_M.gguf, there is no login screen. There is no terms of service to accept. You get the output immediately. That is the standard we apply to Blokhead.
In an era of complex enterprise suites, standalone blockers prove that targeted friction is often more effective than broad restrictions. Enterprise suites try to restrict everything at once, which leads to workarounds and eventual rebellion. Targeted friction, applied only when you need it, is sustainable. Tools like Blokhead demonstrate that effective utility prioritizes "just works" interactions over feature bloat. We don’t bolt on fake workspace suites because somebody wanted a slide deck; we provide exactly what is needed to block the distraction.
Core Features for Immediate Discipline
The quick-add flow allows users to paste a domain or regex pattern and instantly activate blocking without friction. This covers simple sites like reddit.com as well as complex patterns that need wildcards. We support domain, wildcard, and regex inputs so you can catch variations of a distracting site without manual entry for each subdomain. The extension activates immediately upon confirmation, bypassing any setup screens.
Schedules let you define specific hours for focus (e.g., work hours) while keeping evenings open for leisure. Not every hour needs the same level of discipline. You might want to block social feeds during work hours but keep them accessible after 6 PM. The extension handles this logic locally, applying rules based on system time without querying a server. This ensures your personal schedule remains private and that the tool behaves exactly as you define it.
Managed Mode introduces a PIN requirement to disable the extension, creating deliberate friction against impulse unblocking. This is the feature we care about most. When you are in the zone, you don’t want to be interrupted by popups asking you to sign out or re-authenticate. But if you lose focus and want to block the site, you can set a PIN. To disable the extension entirely, you must enter that PIN. That friction is the feature; it forces a conscious decision rather than an accidental click. This mirrors how we designed PomoTok to support focus without turning it into a performance—tools should stay out of the way but still do something genuinely useful.
Customization Without Surveillance Theater
Six distinct themes (Default, Night Shift, Bohemian, Mythic West, Kawaii, Coquette) unify the popup, sidepanel, and block screens. These aren’t just cosmetic choices; they are part of the user experience. When you block a site, you want to see something that reinforces your intent. The themes re-skin the interface consistently across all interactions, ensuring the tool feels cohesive regardless of which extension tab you open.
Users can inject stoic quotes, fitness mantras, or custom messages directly into the block page to reinforce intent. Instead of a generic "You are blocked" message, you can set a reminder like "Focus on code" or "One task at a time." This turns the block screen into a moment of reflection rather than just an error state. The tool operates locally with no cloud dashboard, ensuring zero surveillance or data collection on browsing habits. Your custom messages and schedules never leave your machine.
Where This Philosophy Fits Small Team Software
Tools like Blokhead demonstrate that effective utility prioritizes "just works" interactions over feature bloat. We apply this same philosophy to our security and AI tooling. For example, L-BOM is a small Python CLI that inspects local LLM model artifacts such as .gguf and .safetensors files and emits a lightweight Software Bill of Materials (SBOM) with file identity, format details, model metadata, and parsing warnings. It does exactly one thing well and nothing more. In an era of complex enterprise suites, standalone blockers prove that targeted friction is often more effective than broad restrictions.
Similarly, Ridge Sight allows GitHub users to view and manage all pull requests available to their repositories in one dashboard without needing a heavy IDE installed. Just like Blokhead, it respects the user’s time and intent by providing immediate access to data they need without unnecessary overhead. We believe that whether you are inspecting model files or blocking distracting websites, the tool should be an extension of your workflow, not a barrier to it.
If you are looking for a Chrome, Edge, or Firefox extension that respects your discipline without demanding setup, visit Blokhead. It is available with 7 days free and can be cancelled anytime. We also maintain open-source projects like L-BOM and GUI-BOM if you prefer to handle SBOM generation locally without a GUI wrapper.
