Unused integrations are gone

HubSpot, Cloudflare, customer Resend, Datadog, Amplitude, AWS, Railway, Neon and PlanetScale are no longer offered.

• HubSpot is no longer a connectable CRM. Contacts were never paying customers and never wrote billing metrics.
• Cloudflare is no longer a connectable CDN. Edge request volume was never unique visitors.
• Customer Resend is no longer a connectable email slot. Seiton still sends briefings with its own Resend key.
• Datadog, Amplitude, AWS, Railway, Neon and PlanetScale coming-soon tiles are gone. Hosting is Vercel; database is Supabase.
• Existing connections for those providers are disconnected when the matching migrations are applied.
