Connect Any API
From Your No-Code App
Works in the Designer but fails when deployed? Fix CORS errors in Bubble, Webflow, Retool, and any no-code platform with one simple URL prefix.
"Works in Preview, Fails on Deploy"
No-code platforms run API calls from your browser. When the external API doesn't allow your domain, the browser blocks the request—even though it worked perfectly in the Designer preview.
Access to fetch at 'https://api.example.com' from origin 'https://yourapp.webflow.io' has been blocked by CORS policy
Designer previews often use proxies or development environments that bypass CORS. Your deployed site doesn't have that luxury.
B Bubble.io
"Attempt to make the call from the browser" option triggers CORS errors when the API doesn't whitelist your Bubble domain.
W Webflow
Webflow Logic runs client-side on deployed sites. External APIs must explicitly allow your domain—most don't.
R Retool
Workflow webhooks and external JavaScript libraries get blocked when they don't authorize Retool's domain.
Just Add a URL Prefix
Route your API calls through CORSPROXY. We add the headers the browser needs, and your request goes through.
Payment APIs
Connect to Stripe, PayPal, or payment processors from your no-code checkout flows.
Airtable & Notion
Fetch data from your Airtable bases or Notion databases into Webflow or Framer.
Chat & AI APIs
Add AI chatbots or integrate messaging APIs into your no-code apps.
Maps & Location
Integrate geocoding, address lookup, and mapping APIs into your apps.
Weather & Data
Pull weather data, stock prices, or any public API into your dashboards.
CRM & Email
Connect to HubSpot, Mailchimp, or any CRM API from your landing pages.
