Klaxon

Klaxon enables reporters and editors to monitor scores of sites and files on the web for newsworthy changes. Get email and Slack notifications when something changes.

Get emailed when a website changes

Klaxon is a free, quick to set up and easy to use robot that checks websites regularly so you don't have to. You list websites you want monitored and Klaxon will visit them and, if they change, email you what's different. It saves you having to reload dozens of links yourself every day. It's perfect for monitoring website changes you might miss, like freedom of information disclosure logs, court records, and anything related to Donald Trump. And it can even send notifications to your Slack channel.

Alerting journalists to changes on the web

Built and refined in the newsroom of The Marshall Project, Klaxon has provided our journalists with many news tips, giving us early warnings and valuable time to pursue stories. Klaxon has been used and tested by journalists at The Marshall Project, The New York Times, the Texas Tribune, the Associated Press and elsewhere. The public release of this free and open source software was supported by Knight-Mozilla OpenNews.
