Limiter 0.14.1

Limiter 0.14.1

Limiter is a Windows network monitoring and traffic control prototype built with WPF and WinDivert. This release includes the changes since v0.12.

New features

• NetLimiter-inspired toolbar with global Limiter and Blocker switches. Pause enforcement while monitoring continues and saved rules remain intact.
• Independent download and upload blocking for applications and individual processes. Blocking takes precedence over speed limits.
• Direction switches enable or disable speed limits without clearing their saved values.
• Activity and Rule List views, application search, and a resizable application details panel.
• Clickable sorting headers with a highlighted active column, direction arrows and a description of the current sort order.
• Settings tab with English and Turkish interface languages. The default follows the system language, with English as the fallback for unsupported languages. Language changes apply without restarting.
• Optional start with Windows through a per-user elevated Task Scheduler entry. Disabled by default; no password is stored.
• Self-contained EXE and MSI installers with optional desktop shortcut and Windows startup registration, plus a single-file portable EXE and a portable ZIP. Separate .NET installation is no longer required for these packages.
• Application icon and SHA-256 package checksums.

Fixes and improvements

• Keep the details panel layout stable when global Limiter or Blocker switches change.
• Remove the dotted focus outline around the details scroll area.
• Reserve the "Coming soon" label for Priorities; disabled rule controls no longer display it when no application is selected.
• Save language preferences before updating the interface, and roll back the startup switch if registration fails.

Documentation and licensing

• English README and Turkish README with interface previews rendered using sample data.
• GPLv3 licensing with an attribution preservation term in NOTICE. Distributions must retain the original project attribution and meet GPL source-code requirements.
• Packages include LICENSE, NOTICE and the WinDivert license.
• GitHub Releases are published only for version tags, using the matching English Markdown file under docs/releases.

Installation

1. Run the EXE or MSI installer, run the portable EXE directly, or extract the portable ZIP to a folder.
2. The installers offer an installation folder, desktop shortcut and Start with Windows. The two optional settings default to off.
3. Close any previous Limiter instance, then run Limiter.exe and approve elevation.

With the ZIP, keep WinDivert.dll and WinDivert64.sys alongside the executable. The single-file portable EXE extracts its dependencies into the .NET cache. Download and upload limits use KB/s (1024 bytes per KB); 0 means unlimited and the minimum positive limit is 16 KB/s.

If start with Windows is enabled and you move the application, turn that option off and on again to update its path. Application rules remain under %LOCALAPPDATA%\Limiter\rules.json; language preferences are stored in settings.json in the same folder. PID rules are temporary.

Known limitations

• Traffic control requires Limiter to remain open; there is no separate Windows service.
• Priorities is not implemented yet.
• Existing UDP connections may not be matched to a process. IPv6 extension headers, fragmented packets and loopback traffic are outside the limiting and blocking scope.
• Queue overflow drops packets. TCP retransmits; UDP data can be lost, and transfer rates can fluctuate at low limits.
• Automated checks do not cover real desktop interaction, a complete Windows sign-in cycle, or long-running TCP/IPv6 load.

Limiter 0.12

Limiter 0.12 Windows x64 MVP.

Includes application-wide and PID-specific download/upload limits, expandable process groups, app icons, search, and traffic monitoring.

Requires .NET 8 Desktop Runtime and administrator privileges. Extract the ZIP and run Limiter.exe. PID rules last for the current process lifetime; application rules are persisted locally.

WinDivert license is included in the package. Current engine checks passed; sustained live traffic testing remains important.
