Both tools help you track where leads come from. But they take very different approaches. Here is an honest, side-by-side comparison to help you choose.
Attributer.io is a lightweight script that captures marketing attribution data and populates hidden form fields. It does one thing and does it well -- it gets attribution data into your CRM via form submissions.
SourceStream does the same form field population, but also includes a real-time attribution dashboard, webhook integrations, and a dedicated analytics platform. It is a more complete solution at a lower price point.

Attributer focuses purely on populating hidden form fields with attribution data. It does not provide a dashboard or analytics interface. This means you rely entirely on your CRM's reporting to analyze attribution data. For teams that live in their CRM, this can work well.
SourceStream does everything Attributer does (form field population, UTM capture, channel categorization) plus gives you a dedicated real-time dashboard to analyze your attribution data. You also get webhook integrations for sending data to other tools like Zapier, Make, and n8n.
Both tools solve the same core problem: getting attribution data into your CRM. Attributer is a solid, focused tool that has been around since 2016. But SourceStream gives you more features at a significantly lower price. If you want attribution data in your CRM and a dashboard to visualize that data, SourceStream is the better value.
