Memberstack Alternatives for SaaS: Top 5 Platforms

Before we compare alternatives, let's clarify what Memberstack does:

Memberstack is a membership platform that lets you add login and payment processing to any website. You can use it on Webflow, WordPress, or custom HTML. It handles:

• User authentication (login/signup)

• Payment processing (subscriptions and one-time purchases)

• Member-only content gating

• Account dashboards

• Basic email integrations

It's popular with creators, agencies, and Webflow designers because it's purpose-built for building membership sites on headless/no-code platforms.

The catch: Memberstack alone doesn't include email marketing, CRM, or analytics. You're connecting it to other tools. And it can get expensive fast if you need advanced features.

That's why people search for alternatives.

The Problems People Run Into

1. Pricing Doesn't Scale Well Memberstack charges per member after your first 500. If you grow to 5,000 members, costs add up quickly. At that point, some alternatives are cheaper.

2. Limited Feature Depth Memberstack is good at the basics (auth + payments). But it doesn't include email marketing, CRM, or advanced analytics. You're gluing together 3-4 tools anyway.

3. WordPress Developers Want Native Solutions If you're building on WordPress, you want a tool built for WordPress (not Webflow). Native integrations matter.

4. You Need an All-in-One Some founders just want one dashboard for everything: auth, billing, CRM, email. Memberstack is only 2 of those 4.

5. You Want Open-Source Flexibility Memberstack is proprietary. If you want to self-host or maintain control of the codebase, it's not an option.

If any of these resonate, keep reading. One of these five alternatives is probably better for you.

1. Outseta — Best All-in-One Alternative

Best for: SaaS founders who want auth + billing + CRM + email in one platform

What it is: A complete membership and billing platform built specifically for SaaS. Outseta is what you get if you combine Memberstack + Stripe + email marketing + CRM into one product.

How It Compares to Memberstack

Why You'd Choose Outseta

• One dashboard for everything. No tool-jumping. Everything talks to everything.

• Cheaper at scale. Memberstack's per-member pricing gets expensive. Outseta is flat-rate until you hit revenue thresholds.

• Built for SaaS revenue models. Handles subscriptions, trials, dunning, and seat-based pricing natively.

• Customer success tools included. NPS surveys, customer data, email campaigns—all built in.

Why You'd Stick with Memberstack

• Webflow is your home base. Memberstack is purpose-built for Webflow. Outseta requires hosting your app elsewhere.

• You want maximum design control. Memberstack lets you customize every HTML element. Outseta is more opinionated.

• You're building a custom web app. Memberstack plays nicely with any frontend. Outseta is full-stack.

Pricing

• Memberstack: Free up to 500 members, then $0.10 per member/month (so 1,000 members = $50/mo minimum)

• Outseta: $37/mo, scales with revenue (stays $37 until ~$50K MRR, then percentage-based)

Verdict: If you want a drop-in replacement for Memberstack that costs less and does more, Outseta wins. If you're married to Webflow or need extreme design control, Memberstack stays better.

2. Stripe Billing + Clerk — Best for Developers

Best for: Engineers who want maximum flexibility and control

What it is: Two separate tools that work together beautifully:

• Clerk handles authentication (login/signup, SSO, multi-factor auth)

• Stripe Billing handles subscriptions, invoicing, and dunning

Together, they cover everything Memberstack does—but with more power and customization.

How It Compares to Memberstack

Why You'd Choose Stripe + Clerk

• Unlimited customization. You control the entire UX. Clerk and Stripe are just APIs.

• Better developer experience. Both have first-class SDKs. Build exactly what you want.

• Cheaper at massive scale. Stripe charges a percentage (2.9% + $0.30). Clerk is free. No per-member tax.

• Best-in-class payment handling. Stripe Billing is the gold standard for subscription management.

• Works with any frontend. React, Vue, custom HTML—whatever you're building.

Why You'd Stick with Memberstack

• Faster to launch. Memberstack has a UI you can configure. Stripe + Clerk requires code.

• No engineer required. Non-technical founders can build with Memberstack alone.

• Content gating is built-in. Memberstack has native content-gating widgets. With Stripe + Clerk, you build it.

Pricing

• Memberstack: $0.10 per member/month (after 500 free members)

• Stripe + Clerk: Stripe: 2.9% + $0.30 per transaction. Clerk: Free tier covers 10K monthly active users.

Verdict: If you have an engineer and want the best-in-class tools, this combo is unbeatable. If you're non-technical, Memberstack is faster.

3. Supabase Auth + Stripe — Best for Custom Builds

Best for: Founders who want open-source, self-hosted options

What it is: An open-source PostgreSQL backend with built-in authentication, combined with Stripe for payments.

Supabase is like Firebase but open-source. You get a SQL database, auth system, and API layer. Add Stripe for payments, and you have everything Memberstack does—but you own the code.

How It Compares to Memberstack

Why You'd Choose Supabase + Stripe

• You own the code. No vendor lock-in. Self-host if you want.

• Extremely cheap. At small scale, this is 1/3 the cost of Memberstack.

• Open-source community. Bugs get fixed faster. Security audits are transparent.

• SQL database included. You're not limited to what Memberstack lets you store. Build whatever you want.

• Self-hosted option. Run on your own infrastructure if regulatory requirements demand it.

Why You'd Stick with Memberstack

• Memberstack is managed. Supabase requires you to manage your own backend.

• Faster to launch. Memberstack: point-and-click. Supabase: requires backend code.

• Content gating is easy. Memberstack handles this. With Supabase, you build it.

• No DevOps headaches. Supabase requires database management, backups, scaling decisions.

Pricing

• Memberstack: $0.10 per member/month

• Supabase + Stripe: Supabase: Free tier or $25/month for managed. Stripe: 2.9% + $0.30.

Verdict: If you're a developer, value control, and want to keep costs low, this is the cheapest option. If you want managed infrastructure, Memberstack requires less work.

4. Kajabi — Best for Creators

Best for: Course creators, membership communities, and digital product sellers

What it is: An all-in-one platform for creators that bundles memberships, courses, email marketing, and affiliate programs.

Kajabi is to creators what Outseta is to SaaS founders. If you're selling courses or digital products with memberships, Kajabi is purpose-built for that.

How It Compares to Memberstack

Why You'd Choose Kajabi

• Built for creators. If you're selling digital products or memberships, Kajabi is purpose-designed for this exact use case.

• Everything included. Memberships, courses, email, affiliate management, community forums—all in one platform.

• Content dripping is built-in. Release lessons over time automatically.

• Community features. Members can interact with each other. Kajabi handles moderation.

• Affiliate system included. Let members refer others and earn commissions.

Why You'd Stick with Memberstack

• Kajabi is expensive. Starts at $149/month. Memberstack is $40-50/month at similar scale.

• You don't need all the features. If you're just doing memberships (not courses or community), Kajabi is overkill.

• Webflow + Memberstack is lighter. If you're building a custom site, Memberstack is more flexible.

Pricing

• Memberstack: $0.10 per member/month

• Kajabi: Starts at $149/month (covers unlimited members, courses, email, community)

Verdict: If you're a creator selling digital products with communities, Kajabi pays for itself. If you just need membership payments, Memberstack is cheaper.

5. MemberPress — Best for WordPress

Best for: WordPress site owners who want a native membership solution

What it is: A WordPress plugin that adds membership functionality directly to WordPress. No external platform needed—everything lives on your site.

If Memberstack is for Webflow, MemberPress is for WordPress. It's a native WordPress solution.

How It Compares to Memberstack

Why You'd Choose MemberPress

• WordPress is your home. If you're already on WordPress, MemberPress is a plugin. No new platform.

• Native content gating. Restrict posts, pages, and downloads directly in WordPress.

• Cheaper than Memberstack. One-time purchase (~$100-200) plus Stripe processing.

• Easy to customize. Modify the plugin code or use WordPress plugins to extend it.

• No vendor lock-in. Everything lives on your server.

Why You'd Stick with Memberstack

• Memberstack handles Webflow. If you're on Webflow, you can't use MemberPress (it's WordPress-only).

• MemberPress has limits. As your membership grows, you'll outgrow the plugin.

• WordPress plugin fatigue. You'll need multiple plugins for email, CRM, and analytics.

Pricing

• Memberstack: $0.10 per member/month (after 500 free)

• MemberPress: One-time license (~$150-300) plus Stripe processing (2.9% + $0.30)

Verdict: If you're on WordPress and want simplicity, MemberPress wins. If you want modern SaaS features, Memberstack is better.

When Memberstack is actually the best choice:

• You're on Webflow and love it

• You need extreme design control

• Your membership model is simple (flat pricing)

• You have under 5,000 members (costs are reasonable)

• You don't mind connecting external tools for email/CRM

Memberstack isn't perfect, but it's genuinely good at what it does. It's the best Webflow membership platform. If that describes you, stop searching—you've already found the answer.

Sometimes the alternative is... the original.

If you've been using Memberstack and want to switch, here's the migration path:

Step 1: Export Your Data

• Export members and payment history from Memberstack

• Memberstack provides CSV exports of your customer list

Step 2: Set Up Authentication in New Platform

• Create accounts in your new platform (Outseta, Kajabi, etc.)

• Test login flows before migration

Step 3: Migrate Payment Processing

• Set up Stripe in your new platform

• Decide: new customers on new platform, existing customers stay on old platform (cleanest option)

Step 4: Update Your Content Gating

• If staying on Webflow: use new platform's auth codes in Webflow

• If leaving Webflow: port content to new platform or use embedded dashboard

Step 5: Communicate with Members

• Email members about the change

• Provide transition period (30 days minimum)

• Test edge cases (password resets, failed payments, etc.)

Timeline: 2-4 weeks for a proper migration. Don't rush this.

You should migrate away if:

• Costs are crushing you (>$1,000/mo on Memberstack while similar product costs $100-200 elsewhere)

• You need features Memberstack doesn't have (CRM, email marketing, etc.)

• You're scaling beyond Webflow (moving to custom code)

• You want to self-host or avoid vendor lock-in

You should stay with Memberstack if:

• You love Webflow and want native integration

• Your membership model is simple and costs are reasonable

• You're not ready for another migration project right now

• You have under 1,000 members and costs are <$200/mo

There's no shame in staying. Tool migrations are painful. If Memberstack is working, it's not broken.

Q: Is Outseta cheaper than Memberstack?

A: At small scale (100 members), they're similar (~$37-50/mo). At large scale (5,000+ members), Memberstack gets more expensive (per-member costs add up), while Outseta stays flat-rate until you hit revenue thresholds. Memberstack: ~$500/mo for 5,000 members. Outseta: still ~$37-50/mo.

Q: Can I use Stripe + Clerk without an engineer?

A: No. You need backend engineering to wire these together. Both are API-first tools designed for developers.

Q: Is Kajabi worth $149/month for just memberships?

A: No. If you just need memberships and payments, Memberstack or Outseta are better. Kajabi pays for itself when you're also selling courses or running a community.

Q: Can I self-host Memberstack?

A: No, it's proprietary SaaS only. If self-hosting matters, look at MemberPress or Supabase.

Q: Will migrating break my member data?

A: Not if you plan it right. Export your data, test the new platform thoroughly, and do a parallel run (keep old system live while testing new system). Most migrations take 2-4 weeks.

Memberstack is good at one thing: being the best Webflow membership platform. For that specific use case, it's hard to beat.

But if you're outgrowing Webflow, managing costs, or need features beyond membership auth and payments, the alternatives above are worth evaluating.

Here's our hierarchy:

1. 1. Using Webflow? → Stick with Memberstack or try MemberPress on WordPress

2. 2. Building SaaS? → Outseta (simpler) or Stripe + Clerk (more control)

3. 3. Selling digital products? → Kajabi (includes everything you need)

4. 4. Want to self-host? → Supabase + Stripe (most control, cheapest long-term)

Each has a place. The best platform is the one that matches your specific situation.

If you're on Memberstack today and thinking about alternatives, run the numbers on your actual use case. We bet one of these five will save you money or solve a problem Memberstack can't.
