Its UI/UX is really good, the ways to filter an audience to recruit is quite complete.

Lyssna is very easy to use and affordable

Lyssna's mix-and-match study builder is its main asset. You can easily combine different methods, task types, etc. in a fairly flexible way. The builder UI is intuitive (easy to navigate with keyboard, supports bulk pasting to build response trees, functional Figma integration), and data export is rich (although occasionally plagued with special character issues). It is very good for quick, single-purpose studies with rapid recruitment and flexible screening tools. I often don't need to write custom screeners because they collect a lot of demographic data you can use when building your sample - for example, if I want to survey homeowners, I can select that attribute rather than writing a screener question (for which they charge extra...).
