Being Fat sucks, Cull the calories.
FitShield is not here to yell at you. It is a lightweight browser extension that adds friction between a rough craving and the delivery checkout: block delivery sites, fast-food sites, custom domains, country groups, and food categories on your own terms. Recent releases added private on-device stats, clearer block reasons, backup and restore, Firefox support, and calorie-aware recipe swaps when FitShield catches a craving. An early preview of the native Android app is available from GitHub Releases too.
Features
Here is what FitShield can do right now.
Fast-food blocking
Major fast-food chains are built in, with individual site toggles when you want a tighter or looser shield.
Expanded global blocklists
FitShield reads metadata-rich JSON lists with domains, countries, regions, categories, and searchable specialties.
Country search
Search by country name or code, then block every listed brand that operates there.
Category search
Search food categories like pizza, burger, coffee, dessert, or grocery and block a whole habit lane at once.
Quick-access toggles
Pin selected countries and categories so the groups you care about are easy to switch on or off later.
Custom blocklist
Add your own domains, normalize messy URLs, and enable or disable custom entries without editing files.
Whitelist-style exceptions
Turn off individual built-in sites or custom entries when something should stay open. FitShield stores those choices locally.
Calorie-aware recipe suggestions
The warning page can show one vegetarian idea and one meat or protein idea from a local recipe catalog, matched to the blocked site's metadata when possible. Choosing one can add avoided calories to your private local stats.
Timer and temporary unlocks
Blocked sites hit a pause screen first. After the countdown, one site can open for your configured pass window.
Scheduled blocking
Keep the shield active all day or arm it only during daily danger hours, like late-night delivery browsing.
Language controls
Choose the language FitShield uses for its own screens, or follow your browser's system default. The setting is local to the extension.
Theme customization
Use system, light, or dark mode, then tune colors, corner radius, and popup width so the blocker feels like your tool.
Privacy-friendly design
Settings, aggregate stats, recipes, backups, and update state live in browser extension storage. FitShield does not need analytics, ads, or invasive tracking to block sites.
In v0.53
Recent releases turned the blocker into a fuller habit dashboard.
FitShield still blocks locally, but the extension now does more after the pause: it explains why the block happened, helps you pick a real meal, and keeps simple progress stats on your device.
Private on-device stats
Track blocked visits, money saved in your local currency, and calories avoided. Meal cost and calories start from regional defaults and stay editable, with no browsing history stored.
"I'll make this instead"
The block page suggests a vegetarian and a meat idea with full steps. "I'll make this instead" is now a real button that logs the calories you skipped.
Clear block reasons
Every pause page can show the domain, rule type, food category, and country context that triggered the block.
One shared source tree
The same code runs on Chromium and Firefox 140+ (Firefox for Android 142+), and the build outputs a clean package per browser. FitShield is now listed on Firefox Add-ons, so Firefox installs it in one click. A native Android app preview, downloadable from GitHub Releases, rides the same engine and blocklists.
Backup, restore, and reset
Export or import every setting as one local JSON file, and reset safely with clear confirmations, down to a full factory reset.
Onboarding and What's New
New installs get a quick setup for language, theme, block groups, and optional backup import. Updates can surface the latest changes.
A dashboard you arrange
Settings reflow across wide screens and stack on narrow ones. Drag the cards into the order you want and FitShield remembers your layout.
Living local interface
A layered ambient background drifts, shifts with the time of day, and reacts as you scroll, varying on each open and pausing for reduced-motion.
Current beta data
The beta data is bigger, more searchable, and more useful at the pause screen.
FitShield now reads metadata-rich JSON blocklists with apex domains, country codes, region tags, primary categories, and searchable specialties. Country and category blocks add to the normal site toggles, and calorie-aware recipe suggestions use the same metadata to offer a practical next step.
- Delivery coverage includes platforms, marketplaces, grocery, meal delivery, quick commerce, and venue ordering.
- Food categories include burger, pizza, chicken, coffee, sandwich, bakery, dessert, smoothie, tea, seafood, and more.
- Metadata blocks are additive, so country and category choices work alongside delivery, fast-food, custom, and exception toggles.
- Recipe suggestions are bundled locally, selected on the warning page, include calorie estimates, and do not require a network call.
- Localized extension screens can follow the browser or use a saved display-language override.
- Stats, onboarding state, and What's New state stay in local browser extension storage. Backup files are created only when you choose to export them.
FAQ
Questions people ask before installing FitShield.
Short, honest answers about what the food delivery blocker does, what it can block, and what it never touches.
What is FitShield?
FitShield is a free, open-source browser extension and food delivery blocker. It adds a short pause between a craving and the checkout page on delivery and fast-food sites, so ordering is a deliberate choice instead of an automatic one. Everything runs locally on your device.
How does FitShield block food delivery sites?
When you open a covered ordering site, FitShield redirects it to a calm pause screen with a countdown timer. After the timer you can continue if you still want to, open a temporary pass, or pick a quick recipe instead. It relies on your browser's built-in blocking rules, so your list never leaves your device.
Does FitShield block DoorDash, Uber Eats, and Grubhub?
Yes. Major delivery platforms like DoorDash, Uber Eats, and Grubhub are part of the built-in blocklist, alongside thousands of delivery and fast-food domains. You can toggle any of them on or off.
Can I customize what gets blocked?
Yes. You can turn individual sites on or off, add your own custom domains, and block whole groups by country or food category. You can also keep a site open with a whitelist-style exception when you genuinely need it.
Is FitShield free?
Yes. FitShield is completely free and open source under the GPLv3 license. There are no accounts, no ads, and no paid tier. Donations are optional and never required.
Does FitShield collect personal data?
No. FitShield is built to be privacy-friendly. Settings and aggregate stats stay in your browser's local storage, there are no analytics or trackers, and it does not send your browsing history or blocklist choices to any server. See the Privacy Policy for details.
Can I temporarily disable blocking?
Yes. After the timer you can grant a temporary pass for a single site, set scheduled blocking hours, or switch the whole shield off from the popup. You stay in control.
Is FitShield a Chrome extension?
Yes. FitShield is a Chrome extension that works on Chromium browsers like Chrome, Brave, and Edge through the Chrome Web Store. Firefox users can install it from Firefox Add-ons on Firefox 140+. On Android, Firefox for Android 142+ can install the same extension, and a preview APK of the native Android app is on GitHub Releases.
Is FitShield meant to replace nutrition or medical advice?
No. FitShield is a self-control and digital wellness tool that helps you build healthier habits by adding friction to impulse ordering. It is not medical, nutrition, or addiction-treatment advice, and it does not promise weight-loss results.
Ethos
A free tool for your growing fitness toolbox.
FitShield is for people who like convenience, but do not want dark patterns, coupons, countdowns, and glossy food photos making the decision for them.
You still make the choice. FitShield just gives you a pause, a timer, and a little distance before convenience wins by default.
FitShield is GPLv3 software. You can read the code, audit it, modify it, and contribute improvements. The blocker should help you build better habits without taking away your software freedom.
