System-wide network shaping without proxy setup beats Clumsy for modern Windows testing.

Strengths

•System-wide traffic shaping requires zero proxy setup or code changes.
•Timeline scenarios let you script changing conditions like tunnel blackouts.
•Repeatable seeded randomness ensures bugs can be reliably reproduced.

Weaknesses

•Windows-only limits adoption for cross-platform development teams.
•Closed source currently, though author plans to open source later.

Post Description

Hello, I took "a small break" from gamedev, and I had created Bean Network Tester, a tool for simulating bad network conditions on Windows, so you can test how apps and games behave under weak WiFi, 3G, high latency, jitter, packet loss, etc. Two ways to use it:

Simple: pick a preset (weak WiFi, 3G, …) and hit Start. Advanced: manually set ping, jitter, packet loss and a bunch of other parameters.

There's also a full CLI mode with CI/CD support, and you can script your own scenarios (e.g. add 200ms latency after 30s, then start dropping packets).

It's 100% free for both personal and commercial use. I plan to open source it in the future. It's V0.2 version, but I'm working on a new features + bug fixes.
