Questions & Answers

As answered by people managing BlockSite and ChainBreaker.eu.

What makes your product unique?

ChainBreaker.eu's answer:

ChainBreaker’s distinctive feature is Cementing: you can explicitly lock individual rules against casual editing, disabling or deletion. Releasing a cemented rule requires a separate confirmation and a one-time micropayment, creating a deliberate pause before abandoning a commitment.

This approach works alongside website and application blocking, usage limits, computer schedules and display settings. You choose which rules to cement, so the level of commitment remains your decision.

Why should a person choose your product over its competitors?

ChainBreaker.eu's answer:

ChainBreaker is worth considering if you use Windows and want website blocking, application limits, computer schedules and display controls in one tool.

It is especially suited to people who set useful boundaries but later feel tempted to disable them. Optional cementing adds friction to changing those decisions, while rule explanations show why a restriction is active.

Activity statistics stay on your device. The application requires no user account and offers a 7-day free trial and a one-time device-bound license purchase. Payments to release cemented rules are separate from the license price.

How would you describe the primary audience of your product?

ChainBreaker.eu's answer:

ChainBreaker is designed for Windows users who want more control over distracting websites, applications and time spent at the computer.

Its audience includes students protecting study time, remote workers and freelancers setting work boundaries, and people trying to reduce late-night browsing or excessive gaming, and ofcourse addicts, doomscrollers and so on. People that many times decided on something but later changed they mind when impuls came

It is particularly relevant to users who prefer setting rules in advance and want an optional commitment mechanism to make impulsive changes harder.

What's the story behind your product?

ChainBreaker.eu's answer:

The idea behind ChainBreaker is the gap between making a decision and following it when a distraction becomes tempting. A plan made in a calm moment can be easy to abandon later.

ChainBreaker turns those earlier decisions into practical rules for websites, applications, computer use and display settings. Cementing extends that idea by making selected commitments harder to change casually, while keeping a deliberate release option available.

The guiding principle is to help people follow boundaries they have chosen for themselves.

Its a tool to help keep your own commitments. Chainbreaker makes it harder to betray yourself or even get more freedom of decision and time, by binding your calm decisions harder

Which are the primary technologies used for building your product?

ChainBreaker.eu's answer:

The Windows desktop application is built with Python and PySide6 (Qt), with SQLite for local settings and activity statistics. It integrates with Windows services, Windows Firewall and Windows UI Automation for background enforcement and supported browser activity detection.

The companion website and online services use PHP with Laravel, Vue.js and Inertia.js. Stripe handles payments. Online services support activation, licensing and cemented-rule management.
