It works through redirects. You get one permanent link that randomly shows version A or B (or more) to visitors. Tracks clicks and form submissions. No code installation needed.
Works with any platform that has shareable URLs like Linktree, Carrd, Notion pages, Tally forms, typeform, ...
Main use case I'm seeing:
testing ad with forms funnels (ads → form page → submit) to save ad spend, increase submits.
testing ad with landing page funnels (ads → landing page → product link clicked → shop) to save ad spend, increase clicks, increase revenue.
Can be used to test copy, design and layout, form provider A vs form provider B, ...
Uses minimal cookies for session consistency (eg: always shows A once you've seen A).
A little something I've not found on other tools so added in it: it provides swtchd hosted thank you page so people can use redirect on submit on form-builder to track and optimize provider-hosted forms in minutes.
Would love feedback on whether this solves a real problem or if I'm missing the point, and also if redirects seems fine to use for tracking purpose.
