Jitter Proxy is a lightweight, terminal-based reverse proxy designed for frontend developers and QA engineers. It allows you to simulate network latency (jitter) on any existing API or website to test how your application handles slow connections.
- TUI Dashboard: Real-time request logging (Method, Status, Duration, Path).
- Latency Injection: Toggle artificial delay on/off instantly.
- Smart Configuration: Remembers your settings and latency state between restarts.
- Cross-Platform: Works on macOS, Linux, and Windows.
- Ensure you have Go installed.
- Clone the repository:
git clone https://github.com/ellis3684/jitter.git cd jitter - Build the binary:
make build
Start the proxy by pointing it at a target URL:
# Proxy traffic to Google
./build/jitter --target google.com
# Proxy to local API with a custom 2-second (2000ms) delay
./build/jitter --target localhost:3000 --port 8080 --latency 2000
| Key | Action |
|---|---|
| L | Toggle Latency ON/OFF |
| Q | Quit the application |
| Flag | Default | Description |
|---|---|---|
--target |
https://www.google.com |
The upstream URL to proxy to. |
--port |
8080 |
The local port Jitter will listen on. |
--latency |
500 |
The added delay in milliseconds. |
Jitter automatically saves your settings to config.json on exit. You can also manually edit this file to set persistent defaults.
