NotionLock vs Super.so vs Potion: the honest 2026 comparison

If you're searching for "Super.so vs NotionLock" or "Potion alternatives", you're probably asking the wrong question. Not because they aren't comparable, but because they do different things. This article is an honest comparison of who wins in which scenario, written by one of the three (NotionLock, yes) with the sincere intent of sending you to the right tool, even if it's not us.

The three tools in 30 seconds

• Super.so — historic leader for "Notion as a public website". Excellent for blogs, landings, documentation. Focus: SEO, performance, design tweaks. Price: $16-32/month.
• Potion.so — direct Super.so competitor, similar in scope. Same public features, slightly different pricing, limited free plan. Price: $0-40/month.
• NotionLock — does the opposite job: makes Notion pages private with passwords, paywall, branding. For client portals, paid courses, memberships. Price: $0-9/month.

Scenario 1: I want a Notion blog that ranks on Google

Winner: Super.so (just slightly above Potion). Both have done excellent work on Core Web Vitals, schema markup, sitemap, robots. For serious content marketing, pick them. NotionLock is NOT the choice — private content shouldn't be indexed by design.

Scenario 2: client portal for my agency

Winner: NotionLock, no contest. Neither Super.so nor Potion have native password protection. Super.so has a basic "site password" option but to manage 10+ distinct portals with different passwords and per-client branding, NotionLock is the only one purpose-built for it.

Scenario 3: selling a paid Notion mini-course

Winner: NotionLock + Stripe. No paywall on Super.so or Potion (their sites are public). On NotionLock you password-protect, enable email gate, sell via Stripe Payment Link, send credentials. ~$9/month all-in vs $119/month for Teachable.

Scenario 4: small SaaS documentation

Winner: Super.so or Potion. You want docs to be indexable, fast, with search. Super.so's Notion-doc specialization is very strong. NotionLock isn't the choice — docs need to be public.

Scenario 5: membership site for 50-200 members

Winner: NotionLock. Private hub in Notion, paywall via recurring Stripe, delivery email. $9/month stack vs Memberstack at $25/month or Patreon eating 10%.

Scenario 6: personal portfolio + blog

Winner: Super.so or Potion. You want Google to find you, you want clean design, you want performance. Both deliver. Try them, pick the one that clicks.

Scenario 7: internal knowledge base shared with some clients

Winner: NotionLock. A Notion page with all your product docs, password-protected, shared only with enterprise clients who deserve it. Nothing public, no user accounts to manage.

Can they coexist?

Yes — and it's the most sensible setup if you run a serious business. The recommended stack for a solopreneur or small agency:

• Super.so for the public side: homepage, blog, pricing page, documentation
• NotionLock for the private side: client portals, courses, membership, contracts

Combined cost: ~$25/month. Spend the same $25 on a single traditional tool (Webflow + Memberstack) and you cover much less.

Honest pricing comparison

Single public creator

• Super.so: $16/month
• Potion: $10/month (limited free plan)
• NotionLock: irrelevant, not the use case

Agency client portals (10 portals, branding)

• Super.so/Potion: they don't do this
• NotionLock Pro: $9/month flat
• ClientPortal.io / Service Provider Pro: $30-80/month

Membership of 100 members

• NotionLock + Stripe: $9/month + ~3% Stripe fees
• Memberstack: $25-99/month
• Patreon: 8-12% of revenue (on 100×$19 = $152-228/month)

Verdict

There's no "best". Super.so wins for public and SEO. NotionLock wins for private and paywall. Potion is a valid Super.so alternative. The right way to choose is looking at your actual use case, not comparing feature lists.

If you want to try NotionLock for a private case (portal, paywall, membership): start free here. If you want a public Notion landing: go to super.so or potion.so, they're the right tool.
