Memberstack vs MemberSpace: price, fees and Webflow fit

A free test mode or unlimited members

Memberstack Basic costs $25 a month billed yearly, with a 4% fee and up to 1,000 live members (free and paying members on the live site). MemberSpace Starter costs $24 a month billed annually, with a 5% fee and unlimited members. Pick Memberstack for a Webflow build that wants a free test mode and the lower fee at entry. Pick MemberSpace for any site that wants unlimited members on one annual price. Prices are as read on October 23, 2026.

The table covers MemberSpace vs Memberstack too, and it sits on the yearly view for both. Memberstack also prints monthly billing, at $29 for Basic and $49 for Professional. MemberSpace's pricing page prints annual-billed figures and a Pay monthly instead link, so compare MemberSpace with Memberstack's yearly-billed prices.

Fees and member limits

Both vendors say their fees do not include Stripe's processing fees, so Stripe's card fee comes on top. MemberSpace alternatives compares four tools by fee.

Memberstack's fee falls by plan: 4% on Basic, 2% on Professional, 0.9% on Business and zero on Established. It applies when a member pays, so a site with only free members pays none. MemberSpace charges 5% on Starter and 2% on Growth, and a lower fee comes through a booked call.

The member limits differ in kind. Memberstack caps Basic at 1,000 live members and Professional at 5,000, then upgrades either plan to the next tier automatically at 100%. MemberSpace has no member cap, but Starter installs on one website and Growth on three.

Setup on a Webflow site

Memberstack runs on its own data attributes and an official Webflow app. Its install guide says the Webflow site must allow custom code, and the script goes in the Head code section. MemberSpace asks for one pasted snippet in the header section of the Webflow site, and it describes its own setup as needing no code.

Webflow's memberships directory lists both tools. MemberSpace says it works with any website. Neither vendor's pages name Framer.

Trials, test mode and refunds

Memberstack has no free plan, but its pricing page says every feature is free to try on a test site, with no credit card, for an unlimited time. Its docs put that free sandbox at up to 50 test members, and you pay when the site goes live. Its pricing page lists a 30-day guarantee, and its terms leave refunds to its discretion. Memberstack alternatives sets the two statements side by side.

MemberSpace gives a 7-day free trial. Its terms say billing information may be required to sign up for the trial, and refund requests may be considered case by case.

Where Outseta fits as a third option

Outseta Start costs $37 a month billed yearly, or $47 billed monthly, for up to 1,000 contacts, with a 2% fee, as read on October 23, 2026. Its pricing page does not define a contact, so the count is not the same as Memberstack's live members.

Every Outseta plan lists a CRM, email and a help desk beside authentication and Stripe payments, and Memberstack's comparison page says it works with the CRM an owner already uses. Pick Outseta over either tool when the members area also needs a CRM and a help desk in the same account. Outseta vs Memberstack compares Outseta with Memberstack plan by plan. Outseta's visible pages describe a 14-day free trial, while the structured data (code for search engines that visitors do not see) behind its pricing page says 7 days.
