The Internet remains available. ChainBreaker cuts off only the domains you enter—permanently, on a schedule or after a time limit.

ChainBreaker update · 23 July 2026
The Internet stops being a reflex. It becomes a choice again.
From this version, ChainBreaker can do more than remind you about a boundary. It can restrict the Internet, stop selected websites and guard time spent on the computer, in a browser or on a specific domain—according to rules you choose yourself.
One switch · two opposite strategies
Block selected exceptions, or reverse the rule and leave only what you need.
The menu switch changes all three paired views: permanent rules, schedules and limits. Only one side of the switch is active at a time.
Permanently allowed websites mode
Internet access is restricted while entered domains remain reachable. Schedules and limits can temporarily add the exceptions you need.
01
Selected websites are cut off
The left side of the switch enables permanent blocks, blocking schedules and website-blocking limits.
01
Internet-access schedules
Schedule restriction and restoration just like shutdown or sleep. A weaker rule cannot undo a boundary owned by a higher-priority rule.
02
One switch reverses the whole rule
In the menu, choose between permanently blocked and permanently allowed websites. The related schedule and time-limit views change with the switch.
03
Computer, browser or domain
A limit can use whole-computer time, active-browser time, a specific domain or the most restrictive of those counters. Overlapping time is never counted twice.
04
Your chosen consequence after the limit
ChainBreaker can restrict the Internet, change display settings, sleep or shut down the computer, with a configurable warning beforehand.
05
The boundary is protected
If a shutdown or sleep limit was already exceeded when a later session starts, the app avoids repeating the action in a loop. It shows a decision screen, and raising the limit needs extra confirmation.
06
You know which rule acted
The “Why is this blocked?” panel shows the winning rule, its source, end time and the lower priorities considered in the decision.
Every decision is made locallyRules, counters and the detected active domain stay on your computer. ChainBreaker does not upload browsing history or activity data.
New since 17 July 2026
Boundaries that watch themselves.
ChainBreaker can now count active computer time and automatically change the monitor image after a boundary you set has been reached.
Daily, weekly and monthly limits
Set separate boundaries that reset every day, on Monday or at the beginning of a new month.
Only time you actually use counts
Keyboard and mouse inactivity longer than five minutes is not added to the counter.
An effect after the limit
Grayscale, lower brightness or a stronger hardware blue light filter can be enabled automatically.
The most restrictive boundary wins
When several active limits control the same setting, ChainBreaker chooses the most restrictive one. An active limit also takes priority over a regular monitor schedule.
Features available today
Rules for your computer, displays, Internet and time.
This is the real scope of the application after the update introduced on 23 July 2026—from schedules to local website-access rules.
01
Computer schedules
Shut down or sleep the computer, restrict the Internet and restore access on selected days, times or a one-time date.
02
Monitor schedules
Change brightness, grayscale and blue light filtering automatically.
03
Usage limits
Daily, weekly and monthly boundaries based on active computer or browser time. After a limit, the app can change the display, restrict the Internet, sleep or shut down the computer.
04
Website rules in two modes
Block selected domains while normal Internet access remains available, or restrict the Internet and leave only the websites you need. Both modes include permanent rules, schedules and time limits.
05
Boundaries that survive a closed window
The local network guard and background process maintain active rules after the window is closed and after Windows restarts.
06
Locally stored data
Schedules are kept in a local SQLite database. Your data remains yours alone—the app never shares it with anyone.
Why schedule your display
Fewer stimuli. More room to rest.
A blue light filter for tired eyes
The blue light filter reduces the screen’s blue component, warms the image and helps reduce eye strain during evening computer use.
Grayscale and a calmer dopamine system
Grayscale puts less strain on the dopamine reward system: it reduces the appeal of colorful stimuli and discourages empty, isolated consumption. It becomes easier to step away from the screen and experience the real world more fully.
Easier to let go
A calmer screen can help you end the session, do something else, go to bed earlier and give yourself a chance at longer, fuller sleep.
How it works
Three steps.
One rule.
Choose an area, define a boundary and enable the rule. ChainBreaker stores it locally, resolves priorities and guards it in the background.
Schedules stay on your computerThe app saves them in a local SQLite database.
- 01Choose an area
Computer, display, usage time, Internet access or individual websites.
- 02Define your boundary
Choose the time, days, time limit, domain and the action that should follow.
- 03Enable the entry
The active rule is handled in the background.
The ChainBreaker philosophy
The ChainBreaker philosophy
We have a limited amount of free will that renews each day. Let us preserve it by automating the need to fight ourselves every day. Let us give ourselves the chance to spend it on what comes next.
01
Freedom is, in truth, the choice of our own bonds — the ones that leave us the strength and time to live as we genuinely want.
02
Time is a currency that is forever running out. There is no way to earn more of it. So do not let it be taken from you unnoticed. Let us make sure you spend this resource on exactly what you want. As consciously as you want.
03
Privacy principle
“An app built to restore control should not take control of your data.”

Good to know
Questions about the current version.
Yes. Schedules and settings are stored locally and rule execution does not require a permanent connection.
The app shows a notification with the rule name, scheduled time and a countdown.
Yes. Closing the window can hide it in the tray while schedules remain active.
It counts active computer time. Keyboard and mouse inactivity longer than five minutes is not added to the counter. The result stays in the local SQLite database.
No. For website limits it locally reads only the active domain name from the address bar of a supported browser. It does not store history, page content, URL paths, queries or window titles.
The website rules view shows the winning rule, its source, end time and the lower-priority rules that did not change the result.
In blocking mode, the Internet remains available and selected domains are cut off. In permanently allowed mode, Internet access is restricted and selected domains become exceptions that keep working. The switch also changes the corresponding schedules and limits.
The current desktop application supports Windows 10 and Windows 11.
