Client portals powered by your Notion data

SlapPortal turns your Notion databases into client-facing portals. You configure what external users can see and edit - down to individual properties - and your portal is live. No interface to build, no data to duplicate. Your Notion workspace stays the source of truth.

No! Portal users get their own secure login - no Notion guest accounts needed. You manage them directly from a Notion contacts database.

Portal users log in with a one-time password sent to their email. No sign-up flow, no password to create, no password to remember. They enter their email, receive a code, and they’re in. Simple for them, secure for you.

Notion’s granular permissions are a great step forward but still limited for structured external sharing. With SlapPortal you get:

• Property-level control - Choose which properties each user can see or edit (Notion only allows page-level access).
• Automatic row-level filtering via relations - Show each user only what’s linked to them, their company, or any advanced condition.
• Flexible comments - Hide comments entirely from portal users, or show them and keep specific ones internal by starting them with #.
• A clean portal interface - Your clients don’t land in your Notion workspace. No sidebar, no confusion, no leaked mentions.
• Secure login - No Notion guest accounts needed.

In short: Notion’s permissions are built for internal collaboration. SlapPortal is built for external sharing.

You decide. For each database connected to the portal, you can either:

• Hide comments entirely - Portal users don’t see them, and your team keeps using Notion comments internally as usual.
• Show comments - Portal users can read and post comments, and everything syncs with Notion in real time. To keep some comments internal, just start them with # - they stay invisible to portal users.

Either way, you can tag teammates, have internal discussions, and centralize communication on the right Notion page.

You decide. For each database, you can choose whether portal users see the page body or not. If you show it, SlapPortal renders the full Notion page layout as you designed it - perfect for content approvals, reports, or any page your clients need to see exactly as it looks in Notion. If you hide it, only the properties you’ve made visible are shown.

Yes! You can connect multiple Notion databases and organize them as tabs in the same portal.

Yes! Every change syncs both ways, instantly. Update a property in Notion, your client sees it right away. Your client updates from the portal, you see it in Notion.

Yes! Pair SlapPortal with SlapMail and your clients can reply from the portal or from email - all communication stays synced on the right Notion page.

Security is core to how we build SlapPortal:

• Your Notion data is not permanently stored on our servers. It may be temporarily cached to improve portal performance, but it’s refreshed regularly and not used for anything else.
• Portal user profile data (email, name, picture) is stored securely on EU servers for authentication.
• We passed Google’s security review for SlapMail and apply the same security-first approach to SlapPortal.

Your data lives in Notion, not in Slap. If you stop using SlapPortal, everything stays intact in your Notion workspace - nothing to migrate, nothing to lose.

You’ll need:

• A Notion account
• A Notion database you want to share with external users

Softr and NotionApps are both no-code app builders you can connect to Notion, but they share the same core limitation: you have to rebuild your interface from scratch in their editor, creating a parallel system to maintain alongside Notion.

Softr isn’t Notion-specific. It connects to many data sources, so the Notion integration isn’t its focus. Comments don’t sync with Notion, and your Notion page layouts aren’t rendered.

NotionApps is built for Notion, but it still requires you to rebuild the interface. Data isn’t synced in real time, comments don’t sync with Notion, and page layouts aren’t rendered faithfully either.

SlapPortal takes a different approach. There’s no interface to build - your Notion page layout is preserved as-is, comments sync both ways in real time, and you just configure access rules on your existing data. No parallel system, no duplication.

• Setup takes minutes - no interface to build.
• No lock-in: your data stays in Notion.
• 14-day free trial, no credit card required.

SlapPortal pricing is based on monthly active users - not on the total number of contacts in your database. If you have 1000 users in your contacts database but only 100 actually log into the portal in a given month, you only pay for those 100. It feels fairer to us: you pay for real usage, not for a list.

Yes! Every plan comes with a 14-day free trial - no credit card required. Need more time to evaluate? Just reach out at hello@getslap.co and we’ll extend it.

Yes! You can cancel your subscription at any time from your account. Your data stays in your Notion workspace - nothing to migrate, nothing to lose.

SlapPortal works for any scenario where you need to share Notion data with external users in a controlled way. Common use cases include:

• Client support portals - Let clients view and update their support tickets.
• Agency project tracking - Share project status, deliverables, and timelines with clients.
• Content approvals - Send pages for review and get comments or approvals directly from the portal.
• Client onboarding - Guide new clients through checklists, documents, and next steps.
• Partner or vendor collaboration - Share specific databases, with each partner seeing only their own records.
• Public roadmaps - Let users vote on features or sponsor development.

If you manage it in Notion and need to share part of it externally, SlapPortal can probably handle it.
