Flowstar: Banners

Flowstar: Banners connects with Webflow to add promotional pop-ups and announcement banners to any published site.

Webflow does not include a native banner or pop-up system. Announcing a sale, displaying a site-wide promotion, or showing a floating call-to-action requires custom code or a third-party tool. That gap slows down campaign launches and creates a dependency on developers for time-sensitive updates.

Flowstar: Banners addresses this with a visual banner builder that installs from the Webflow App Marketplace. After a one-click install, you configure banners through a visual dashboard and publish them site-wide or as floating pop-ups. The app injects required scripts through the marketplace install flow, so the documented setup does not require manual code placement.

E-commerce teams running flash sales, agencies deploying client campaigns, and site owners who need promotional messaging without code all benefit from this integration. If you need implementation details beyond the marketplace workflow, public documentation for Flowstar: Banners is limited, so confirm them directly with Flowstar before relying on a custom setup.

How to integrate Flowstar: Banners with Webflow

What is Flowstar: Banners? Flowstar: Banners is a Webflow app that displays pop-ups, promotions, and offer banners on websites. It provides customizable layouts, colors, fonts, and images through a template-driven dashboard. The app supports banners embedded anywhere on a site or shown as floating pop-ups.

The documented way to connect Flowstar: Banners with your Webflow site is through the Webflow Marketplace app.

• The Flowstar: Banners marketplace app handles installation through Webflow with no-code setup  
• Public documentation for manual embed or custom-code installation is limited for this product

Choose the marketplace app for the supported, documented setup path. If you need anything more custom, verify availability and implementation details directly with Flowstar first.

Use the Flowstar: Banners app

The Flowstar: Banners app on the Webflow Marketplace requires the least setup to add banners to your site. After installing, you create and configure banners through a visual dashboard without writing any code. The app handles setup through the marketplace install flow, so you do not need to edit custom code settings or add Code Embed elements as part of the documented installation path.

• Find "Flowstar Banners" at webflow.com/apps and click Install app  
• Click Add to site and select which Webflow site receives the installation  
• Click Authorize app to grant the permissions requested during setup  
• Open the Flowstar dashboard from the Apps panel in Webflow to create banners and configure appearance  
• Publish your site to see banners

This is the fastest path for teams that want banner management inside Webflow without manual script placement.

One important limitation applies when testing banner implementations in Webflow: published output is the reliable place to test banner behavior. Use your staging subdomain (yoursite.webflow.io) to test before publishing to a live domain.

If you need implementation details beyond the marketplace app

Public documentation for Flowstar: Banners installation outside the marketplace flow is extremely limited. The app listing confirms no-code setup directly in Webflow, but it does not publicly document a separate manual embed workflow for this product.

If your team needs page-specific placement, custom loading behavior, or another nonstandard implementation, contact Flowstar at hi@flowstar.co before planning around custom code settings or Code Embed. Webflow supports those features in general, but availability for Flowstar: Banners should be confirmed with the vendor.

If Flowstar provides account-specific instructions, use Webflow’s built-in custom code tools only according to that guidance.

Webflow custom code can support site-wide scripts

Site-level custom code applies scripts to every page at once. In Webflow, you open Site settings (gear icon) > Custom Code tab and paste the script into the appropriate field.

• The Footer Code field places code before the closing </body> tag  
• The Head Code field places code inside <head>  
• Each section supports up to 50,000 characters  
• Click Save, then publish the site to see changes

These are Webflow capabilities, not publicly documented Flowstar: Banners setup steps.

Webflow Code Embed elements can support page-level placement

Code Embed elements let you place HTML or JavaScript at a specific location on a specific page. Open the Add panel (+), search for "Code Embed," and drag it onto the canvas where you want the code to appear. Double-click the element, paste the snippet, and click Save & Close.

• Do not include <html>, <body>, or <head> tags inside Code Embed elements  
• Each Code Embed element supports up to 50,000 characters  
• Code only executes on published sites, not in the Webflow canvas

Again, these are Webflow features. Whether Flowstar: Banners supports this kind of manual placement should be verified directly with Flowstar.

What you can build with the Flowstar: Banners Webflow integration

Integrating Flowstar: Banners with Webflow lets you deploy targeted promotional messaging across your site. You skip building custom banner components or writing display logic from scratch.

• Flash sale announcement pages: Add a floating promotional pop-up to an e-commerce store that announces a limited-time discount. The banner appears across the shopping experience and links directly to a sale collection page. Visitors get immediate context when they land on the site.  
• Event registration landing pages: Place an announcement banner on a conference or webinar landing page. The banner highlights early-bird pricing or remaining seats. It updates through the Flowstar dashboard without rebuilding the full page layout.  
• Product launch campaign sites: Deploy a promotional banner on a SaaS marketing site that announces a new feature release. The banner includes a call-to-action linking to feature documentation or signup pages.  
• Seasonal campaign storefronts: Run a holiday promotion across a Webflow e-commerce store with a branded pop-up that matches the site's design system. Customize colors, fonts, and images through the Flowstar dashboard to align with seasonal creative. Remove the banner when the campaign ends.

These examples show the main value of the integration: faster campaign launches inside Webflow without building custom banner systems from scratch.
