Keep Tabs on What's Happening in Your Product
Get notified about signups, cancellations, payments, and critical moments. Stop spamming Slack. Built for developers who want to stay in the loop without the noise.
Know what's happening. When it happens.
Get notified about critical events in real-time. Trigger webhooks for automation. No more refreshing dashboards or wondering what's going on.
Push Notifications
Get instant browser notifications when critical events happen. Stay aware without constantly checking dashboards.
Mobile App (PWA)
Install on iOS or Android. Get real-time notifications on your phone. Stay updated wherever you are.
Webhook Triggers
Fire webhooks to trigger automations, send Slack messages, or kick off workflows when events occur.
Organized Channels
Group events into channels like signups, cancellations, payments. Just like Slack, but for your product.
Not analytics. Just awareness.
We don't track every click or page view. Just the critical moments you need to know about—signups, cancellations, payments, errors.
Focus on What Matters
Not every click. Not every page view. Just the critical moments that impact your business—signups, cancellations, payments, errors.
Awareness, Not Analysis
Analytics platforms help you understand trends. EmitKit helps you stay aware of what's happening right now.
