       Show HN: We built a permissions layer for Notion
        
       My agency was bleeding $1,800/year on contractor Notion seats. The
       problem: I needed to give contractors access to specific data (CRM,
       project tracker) but couldn't let them see pricing, margins, or
       other clients' information.  Notion's native solution doesn't work:
       Row-level filtering exists but it's view-only (contractors can't
       edit)  Column hiding doesn't exist  Guest sharing is read-only  So
       you either pay $15/mo per seat or duplicate databases (maintenance
       nightmare)  I built a permissions layer using Notion's OAuth API.
       It lets contractors see only specific rows and columns, edit data,
       all without expensive seats.  How it works:  Connect Notion via
       OAuth  Define roles: "Sales reps see only leads where owner = them,
       hide pricing column"  Contractors access a clean portal  They
       view/edit data in real-time (syncs every 5 minutes)  You pay $59/mo
       flat for unlimited users  The math:  5 contractors x $15/mo =
       $900/year wasted  20 contractors x $15/mo = $3,600/year wasted  50
       contractors x $15/mo = $9,000/year wasted  With this: all of them =
       $59/mo flat.  Technical:  Frontend: React + TypeScript  Backend:
       Supabase + PostgreSQL (RLS)  Auth: Notion OAuth 2.0  Current state:
       50 beta testers. First 20 customers get $49/month locked-in
       (launching at $79 after January).  Limitations:  Only Notion
       databases (not pages)  5-minute sync (not instant)  Requires role
       definition  No team permissions yet (roadmap)  The ask: If this
       solves a problem you have, we'd love feedback. Are there permission
       use cases we're missing? What's your price sensitivity?  Free
