BlockDistraction vs Other Website Blockers: Which One Fits You?

Website blockers often share the same headline features: block a site, set a schedule and start a focus timer. The useful comparison is what those features cost in practice. How much blocking is free? How much configuration does a reliable schedule need? Does browsing data stay on your device? And does Android support mean a browser extension or a separate app?

This article is published by the developer of BlockDistraction, so it is not presented as an independent ranking. The goal is to explain where BlockDistraction has a real advantage, where another tool may be stronger, and what to verify before choosing. Product availability and paid plans can change; the comparison links to the official pages checked for this update.

The Short Answer

LeechBlock NG offers deeper free configuration, with more setup concepts to learn. BlockSite adds separate mobile apps, but its data-sharing disclosures deserve close attention. Blockodile offers feed-specific controls and paid accountability tools. Avrodh provides unlimited basic blocking and site-by-site permissions, while its paid license is limited to one device at a time.

Five Website Blockers at a Glance

What BlockDistraction Offers

1. Firefox Android Is a First-Class Platform

Many comparison pages mix up an Android app with an extension running inside an Android browser. They are not the same. BlockDistraction supports website rules inside Firefox for Android, and its Universal License also covers supported Edge builds on Android. The same rule model, Focus controls and Pro activation flow are used across supported desktop and mobile browsers.

LeechBlock NG and Avrodh are also officially available for Firefox Android. The Blockodile Firefox listing checked for this article does not advertise Android compatibility, while BlockSite offers a separate Android app. Android browser support is a reason to consider BlockDistraction, but it is a shared capability rather than a unique feature.

2. You Can Start Without an Account

BlockDistraction Free lets you create up to 10 blocking or redirect rules, use Strict Mode and start fixed 25-minute Focus Sessions without creating an account. An account is needed only when purchasing and activating Pro services.

This keeps the first experience small: install the extension, add a rule and see whether it solves the problem. It also avoids making cloud sync or a profile mandatory for basic browser blocking.

3. Browsing Rules Stay Local

BlockDistraction processes blocking decisions in the extension. Browsing history, blocked addresses, rule contents and daily usage are not sent to BlockDistraction servers. Optional technical analytics and anonymous error reports are disabled by default and do not include browsing activity, URLs, rules, email addresses or license keys.

“Privacy-first” should not mean pretending that a paid product has no network activity. Pro activation sends the license information needed to verify access, and website payments are handled through the account and Paddle. These flows are separate from browser rules and browsing behavior. The complete boundaries are documented in the Privacy Policy.

4. The Interface Stays Approachable Without Stopping at Basic Blocking

A new user can block the current site from the popup or start from reviewed Rule Packs. Pro then adds Rule List profiles, per-rule schedules, Daily Limits, password protection, custom Focus Sessions, Hardcore Mode, statistics and import/export. The product can grow from one simple rule into separate Work, Study or Personal configurations without exposing every advanced concept on day one.

5. One Pro Key Covers Supported Browsers

A Universal Pro License works with supported BlockDistraction builds for Chrome, Firefox and Edge, including supported Firefox and Edge versions on Android. Monthly, Annual and Lifetime options are available, so the license is not limited to a single store or a subscription-only purchase.

6. The Interface Is Available in 57 Locales

BlockDistraction maintains 57 locale packages and checks them as part of its release validation. That does not make the blocking engine stronger, but it matters for people who want settings, explanations and safety prompts in their own language.

BlockDistraction's Limits

• The free plan has a ceiling. It allows 10 blocking or redirect rules. Schedules, Daily Limits, password protection and custom Focus controls require Pro. LeechBlock NG offers more configuration for free; Avrodh and Blockodile offer unlimited basic website blocking.
• It works inside supported browsers. It cannot stop you opening a separate social-media app or switching to a browser where the extension is absent.
• A Universal License shares Pro access, not rule lists. Rules stay local. Moving a setup between browsers uses manual Pro export/import rather than automatic cloud sync.

Competitor Strengths and Trade-offs

LeechBlock NG: deep free rules, more to configure

LeechBlock NG supports up to 30 block sets, combined time periods and allowances, access delays, wildcards, exceptions and keyword rules. That is substantial free functionality, especially when BlockDistraction's 10-rule limit would be too restrictive.

The cost is configuration effort. Its official documentation uses HHMM time ranges such as 0900-1700 and asks you to combine time periods and allowances with AND or OR. Selecting AND while supplying only one condition can leave sites unblocked, a pitfall covered in its troubleshooting FAQ. Basic blocking needs only a few settings, but our view is that these conventions create a steeper learning curve for a beginner. Choose it if that flexibility is worth learning the model.

BlockSite: app coverage with a privacy trade-off

BlockSite combines browser extensions with separate Android and iOS apps, cross-device sync and category controls. That broader coverage is useful when distractions also happen in installed apps.

Check the free plan before building a long block list. Its extension help page says only the Adult category is free; Social, Shopping and other categories require Premium. The official sources checked did not establish a current free site-count allowance, so this comparison does not quote a number.

The larger concern for privacy-conscious users is its privacy policy, updated July 16, 2026. It describes collecting browsing data and disclosing it to affiliates for market intelligence, including onward disclosure to their customers. It also describes possible sale or sharing under U.S. privacy laws, while saying it does not disclose personal information for monetary compensation. Consent is obtained where legally required. The extension offers an opt-out, but the policy warns that some or all services may become unavailable. That is a substantial trade-off to assess before enabling data collection, especially if you only need local browser blocking.

Blockodile: feeds and accountability, with paid extras

Blockodile advertises unlimited free website blocking and controls for selected feeds such as Shorts and Reels. Its Pro features include accountability emails and Google Calendar blocking; browser sync requires an account. Those extras may justify choosing it, but check which tier contains the feature you need. Its Firefox listing does not advertise Android compatibility, so confirm mobile availability separately.

Avrodh: site-by-site permissions, one device per paid key

Avrodh's official website describes unlimited basic website blocking without an account and permission requests for each site you choose to block. It supports Chrome, Edge and Firefox, including Firefox for Android. Scheduling, password protection and backups are Pro features. Its pricing FAQ says each license key is valid on one device at a time and is removed from an older device when used elsewhere. This matters if you want paid controls on desktop and mobile simultaneously.

Which Website Blocker Should You Choose?

• Choose BlockDistraction for local browser rules and one Pro key across supported browsers and devices, if 10 free rules or a paid upgrade fits your needs.
• Choose LeechBlock NG for extensive free rule controls, if you are willing to learn and test its time conditions.
• Choose BlockSite for its broader app ecosystem, after reviewing its free-plan restrictions and data-sharing choices.
• Choose Blockodile for feed-specific blocking, with a Pro budget if you need accountability or calendar automation.
• Choose Avrodh for unlimited basic blocking and site-by-site permissions, accounting for its one-device limit per paid key.

For BlockDistraction, the reason to choose it is the combination of local rules, desktop and Android browser support, an account-free start, 57 locales and one Pro key for supported browsers. Compare that combination against the specific limits and trade-offs above.

How This Comparison Was Checked

This comparison was updated on October 22, 2026 using official product pages, store listings, help documentation and privacy disclosures. It compares documented capabilities rather than a controlled performance test. The assessment of setup effort is our editorial judgment based on the configuration steps described above. Plan terms and availability can change; confirm them before paying. We omit an exact free site allowance where the current official sources did not establish one, and do not rank products by temporary discounts, user counts or star ratings.
