It is similar to the Network tab in Chrome Developer Tools but works for any API: mobile apps, webhooks, frontend etc. After I shared it with a close circle of friends, they found it incredibly useful and even found new use cases, I never imagined. Been a long time lurker here and…

    Hey HN I’m Daniel, a fullstack developer from Sydney Australia and founder at Saas Ninja (https://saasninja.io/).
