About Cordon
Fully-built Notion client-approval portal for agencies - never launched, buy the
Cordon is a fully-built, tested client-approval portal that sits on top of Notion. Agencies invite clients to review and approve items in a Notion database (deliverables, content, invoices, whatever the workspace tracks) through a clean branded portal, without ever giving the client Notion access. Tech stack: SvelteKit, Cloudflare Workers (assets + queues), Postgres via Neon/Hyperdrive, Better-Auth, Paddle for billing (Merchant of Record - works globally, no Stripe account needed). Status: pre-revenue, never launched publicly. Built alongside a sibling product (Veneer, the Airtable version) as part of a small suite of ops tools for agencies; this one just never got its marketing push. Core flows (auth, Notion read/write proxy through a rate-limited token-bucket queue, billing, admin) are done and working, not a prototype. What you get: full source code, ready to deploy on your own Cloudflare account. No customers, no baggage, no technical debt to untangle - you're buying finished dev work and skipping the weeks it takes to build this from scratch. Good fit for: someone who wants to launch a Notion-adjacent SaaS fast, or an agency that wants to white-label a client-approval tool on top of the Notion workspaces they already run for clients.
Project details
Next step: <p>Launch it standalone, or white-label it as a client-approval add-on inside an existing agency/ops product. Extend the same proxy architecture to support other Notion object types, or pair it with Veneer for a combined Airtable + Notion offering.</p>
