Built & maintained by a solo developer who answers their own email — and who's been on the Shopify ecosystem since 2018.
What it is, plainly
A simple way to save extra information about a shopper, right where Shopify already keeps it.
Shopify lets you store any custom data you want on customers, products, pages — they call these metafields. The problem is, nothing in your storefront helps you actually fill them in.
FieldsRaven does. Drop a small snippet into your theme. From any page — checkout, account, a quiz, a configurator — write directly to the customer's Shopify profile.
Everything that already reads metafields — your theme, your Klaviyo flows, your Airtable sync, your team in the admin — picks the data up automatically. No new database. No new app to maintain.

FAQ
The honest answers.
What does FieldsRaven actually do? +
It writes data from your storefront onto Shopify's native metafields. That data is then visible everywhere Shopify already shows metafields — your theme, your admin, your Klaviyo integration, your Airtable sync.
Do I need to write code? +
If you can paste a snippet into your Shopify theme, you can use it. Most stores wire up their first save in under 20 minutes. Anything more complex is a normal theme-customization task.
Will it slow down my storefront? +
No measurable impact on Largest Contentful Paint or Total Blocking Time. The kit is ~3KB gzipped and only fires on the actions you wire it to.
What if my developer wants to install it for me? +
Send them this page and the docs at docs.fieldsraven.app. The integration is small enough that most agency leads finish it in one sitting.
How is this signed / secure? +
Every write is signed by Shopify's app proxy with an HMAC. Only requests that come from your actual storefront can write to your store's metafields. There's no separate auth to manage and no token to leak.
What metafield types are supported? +
Text, integers, and JSON (single line or multi-line). That covers ~95% of real-world cases — birthdays as text, hide-page flags as integers, quiz answers as JSON.
What happens if I uninstall? +
Your data stays on your customer/product/page metafields — it's stored in Shopify, not in our database. We delete our copy of your shop record per Shopify's GDPR webhook on uninstall.
Can I export the saved data? +
The data is in Shopify, so you can use any tool that reads Shopify metafields — the Admin API, the bulk export, Matrixify, etc. There's no FieldsRaven-specific export to learn.
How do you handle Klaviyo? +
When you save a metafield to a customer, FieldsRaven also syncs the value to that customer's Klaviyo profile as a custom property — segmentable, flow-triggering, and available in templates immediately.
What about Airtable? +
Same idea — a save also appends a row to a base you configure, so a non-technical team member can see every save in a normal Airtable view.
Is there a free plan? +
No free tier, but every install gets a 14-day trial with no credit card required at signup. If it isn't useful to your store, uninstall before day 15 and you're never billed.
