DataFast alternative, self-hosted and open source
trckable vs DataFast: the same revenue-attribution idea (which channel brought paying customers), open source and self-hostable, with a smaller script. Sourced facts, and where DataFast is better.
DataFast is a hosted analytics tool built around one question: which marketing channel brought the revenue. trckable asks the same question. This page is for people choosing between a hosted product and one they can also run themselves.
Who each is for
- DataFast suits founders who want revenue attribution hosted for them, plus extras such as social-mention tracking.
- trckable suits founders who want the same attribution open source, on their own server if they like, with cookieless mode available.

Where DataFast is better
- Shopify is supported for revenue; trckable does not connect to Shopify.
- Extras around attribution: social mentions on X and Reddit, link attribution, and an MCP/CLI, on its Growth plan.
- Nothing to run: it is a hosted service, which some people prefer.
How to switch
- Add trckable's script next to DataFast's and run both for a week.
- Connect the same payment provider in Revenue; past payments come from the provider, not from DataFast.
- trckable has no importer for DataFast's data. If you have an export with one row per pageview, the general import may read it; totals will not import.
- Remove DataFast's script.
