Outseta Webflow integration: the app, the head script and CMS sync

The Webflow app or a head script

Yes, Outseta works with Webflow two ways: through its Webflow app, which Outseta calls native, or through a head script, a few lines of code pasted into Webflow's custom code. The app is the plugin route; the head script is the manual one. Both need custom code, which a paid Site plan or a paid Workspace plan unlocks. Every Outseta plan lists authentication, protected content and Stripe payments.

Start is $47 a month billed monthly or $37 billed yearly, as read on October 23, 2026.

Installing the Outseta Webflow app

Start an Outseta account first, because the app asks for your Outseta account address. The trial lasts 14 days on Outseta's visible pages; the structured data (code for search engines that visitors do not see) behind its pricing page says 7 days and a switch to a paid plan unless you cancel, which Outseta pricing explains.

1. Connect Stripe in Outseta and add at least one plan for your members.
2. Install the app from the Webflow Apps marketplace and authorize it.
3. Enter your Outseta address, in the form yourdomain.outseta.com.
4. Copy the head script the app shows into Webflow's Site settings, Custom code.
5. Add sign-up and login forms from the Designer, then publish.

The head script and embeds by hand

By hand, you paste the Quick start head script, then add sign-up, login, profile and logout buttons or links. An embed is an Outseta form that opens as a pop-up or sits on a page. Each button's link setting takes a URL copied from Outseta, and Outseta shows or hides the buttons by login state.

Set the post-login page too; Outseta calls it the most important setting on that screen. Outseta's help center words some steps differently for v2 and v3; Webflow membership site says which to follow. For sign-in options see Webflow user authentication.

Gating pages and syncing CMS items

Content groups protect pages or folders by plan, and the data-o-plan-content attribute shows or hides one element. Outseta describes this gating as JavaScript-based. With the Webflow app, a new member's account-specific page can be published as a CMS item in a folder or collection you choose.

Webflow's free Starter plan has no custom code unless the Workspace is on a paid plan. Memberstack works through its own official Webflow app and data attributes. Pick Memberstack for that route; pick Outseta when billing, CRM and email should sit in one account. Outseta vs Memberstack compares them.
