A local proxy that drops the requests you do not need.
Create an account, download the sidecar, and point a browser at it. Each running sidecar uses one seat. We turn seats on after you pay.
1. Create an account
You will get a setup key on the account page. The sidecar stays quiet until a seat is assigned.
2. Download the sidecar
Mac first. Linux builds are on the same page after you sign in.
3. One process at a time
A sidecar accepts traffic from one local program. Chrome is fine, because its network process is that one program. A second app on the same port is refused. If the sidecar loses the server, it stops forwarding.
