Start in two minutes.

Get a key, download the Mac sidecar, point Chrome at localhost. We activate the key after payment. Without a live lease the sidecar refuses traffic.

1.Get an account key

Create a key here, or we send you one after an invoice. A new key is unpaid until we activate it — the sidecar will answer 402 until then.

2.Download the sidecar

Mac first. Linux builds are here if you need them.

Download for this Mac macOS Intel Linux x64 Linux arm64

curl -fsSL https://HOST/install.sh | sh

3.Setup card

Make it executable and register. This starts the proxy on 127.0.0.1:9001 and the console on 127.0.0.1:9000.
```
chmod +x sidecar
./sidecar setup YOUR_ACCOUNT_KEY
```

Print the CA and SPKI hash:

./sidecar ca > sidecar-ca.pem
./sidecar ca -spki

Point a dedicated Chrome at the proxy and trust that CA (do not use your everyday profile):

open -na "Google Chrome" --args \
  --user-data-dir="$HOME/.filter-chrome" \
  --proxy-server=http://127.0.0.1:9001 \
  --proxy-bypass-list='<-loopback>' \
  --ignore-certificate-errors-spki-list=SPKI_HASH

Open the console at http://127.0.0.1:9000 to add rules. Optional paid upstream:
```
./sidecar setup YOUR_ACCOUNT_KEY --upstream host:port:user:password
```
