I'm Pal, the creator of an open source form/survey platform. It's written in Rust and Svelte and it's all on GitHub: https://github.com/palform/palform.My aim is to do something similar to how Proton encrypted emails: keep it simple and user-friendly, so that basically everyone can switch to it from Google/Typeform.Of course, there's some compromises. You can't really do integrations, since the...
It has all the same features plus many more: advanced conditional branching, webhooks, thorough design customisation, better question types (e.g. address autocomplete), etc.
I've bootstrapped it into a (very) small startup. The idea is to maintain an ethics- and privacy-driven form builder that people don't have to trust, since nobody can see your responses. It also makes GDPR way easier for you!
You can try it for free: https://palform.app
To start with, you get pretty graphs to summarise each question, with the exact graphic depending on the question type (e.g. a heatmap for the "address" input). This is a quick, simple summary and anyone can understand these. They're also easy to download and share.
Then there's correlation analysis, showing which pairs of questions have the most strongly related answers. We summarise this using plain English to ensure people without stats degrees can understand it! You can also view the regression graph for each question pair, which can help determine other patterns.
Despite the complexity, we've done some initial benchmarking (which we're hoping to formalise and publish soon) that shows these analyses perform very well at scale, hardly exhibiting lag even with tens of thousands of responses. Overall, it's a great groundwork that'll be nice to build upon in the future as we add more sophisticated analysis without compromising on the simplicity aspect.
Hope that helps, and thanks for your question :)
Palform addresses my personal concerns with commercial form builders; it places a core focus on privacy by end-to-end encrypting all responses. It doesn't compromise on functionality, containing basically all the features you'd expect from competing tools. It's priced very reasonably with a fairly generous free tier. I'd love some feedback on what you think of the idea/execution!
