CADENCE — Landing Page Copy (draft for the marketing site)

Ready-to-edit copy for the v1 marketing site (a launch-checklist item in gtm-plan.md). Positioning + numbers come from market-research.md / gtm-plan.md. This is copy, not a commitment — pricing/claims are plans until launch.

Hero

Headline: Know when to upgrade — before it breaks production.

Subhead: CADENCE is curated upgrade judgment for self-hosted Proxmox, Ceph, and Nextcloud. Not "an update exists" — "hold this one," "wait for the patch," "upgrade Ceph to Squid before PVE 9." Delivered as a signed feed your own appliance verifies locally. Your inventory never leaves your network.

The problem (three lines)

pve8to9 tells you if your config will break. Nextcloud’s updater tells you an update exists. Neither tells you whether the release itself is wise to install yet. So you find out from a forum thread — at 2am, after the cluster is already down, or after a point release silently disabled Calendar for 200 users.

How it works (3 steps)

  1. We curate. An expert tracks Proxmox/Ceph/Nextcloud releases and writes conditional advisories — holds, wait-for-patch, EOL, and cross-product ordering — into a signed feed.

  2. You pull + verify. Your appliance pulls the feed (or mirrors it air-gapped) and verifies the ed25519 signature against one shipped public key. Nothing proprietary runs in your infra, so the appliance is source-available.

  3. You get verdicts. It reads your local inventory (Proxmox API, Nextcloud occ, NetBox, SSH/apt), evaluates the advisories against it, and shows per-asset verdicts + reminders, and notifies you by email or webhook. Advice only — it never changes your systems.

Why not just use what’s free? (the wedge)

CADENCE is the layer none of them provide: curated, conditional, inventory-aware verdicts — including cross-product ordering ("Ceph must reach Squid 19 before PVE 9") evaluated against your cluster — plus an auditable record of why you held an upgrade.

Features

  • Conditional verdicts — install / install-urgent / hold / wait-for-patch / eol / blocked, gated on your installed apps and other products' versions.

  • Cross-product ordering — the Ceph-before-PVE9 class of mistakes, caught before you make them.

  • Service reminders — "cluster upgrade review overdue," "test-restore a backup."

  • CVE highlighting against your installed versions.

  • Signed + air-gap mirrorable — sync the feed to an internal server and run fully offline.

  • No phone-home — your inventory, topology, and versions stay on your network. Always.

  • Audit trail — a timestamped, reasoned "we held for X" record for NIS2/CRA change management.

One prevented bad Proxmox/Ceph upgrade pays for a year. Start free; upgrade when a second stack or same-day verdicts matter.

Trust & security

  • The appliance is source-available — read every line you run.

  • Feeds are ed25519-signed; the client verifies before trusting anything and fails closed.

  • One-way data flow: the client only ever pulls. It has no path to send your data out.

  • Verify the feed yourself with the published signing-key fingerprint.

FAQ

Does my data leave my network? No. The client pulls a signed feed and evaluates locally. There is no outbound channel for your inventory.

Will it upgrade things for me? No — v1 is advice only. No write-back to your systems.

Can I run it air-gapped? Yes. Mirror the signed feed to an internal server, exactly like a Linux package repo.

Which stacks? Proxmox VE + Ceph and Nextcloud at launch; more self-hosted stacks follow as feed modules — no client changes needed.

What do I actually pay for? The curated feed subscription. The appliance is free and open.
