STATUS AND CHANGELOG
What is running, and what shipped.
Latest in the changelog
- Accounts start with a demo call, then a 90-day free trialAccounts are set up by our team after a demo call: we email you a link to set your password. Each account starts with a 90-day free trial on the Pro plan's limits, with no card. When the trial ends, the dashboard locks and the SDK and the API refuse your keys until our team moves your account to a paid plan.
- Proxies named by timing, in the browserA proxy ends our connection, so our echoes travel on to the browser and back. When that leg is clearly longer than the connection allows, the answer names a proxy, including a residential one that no list covers.
- The line a proxied visit started fromWhen a proxied browser's own WebRTC address belongs to another network operator, the answer names that line's country beside the proxy verdict.
