edgeKey
Digital-goods license-key storefront. Cloned in s1, hardened through s7: English-first pages, a real test order in D1, and a Stripe gateway staged behind one operator ask.
Counterscale
Self-hosted, privacy-first web analytics on Cloudflare Analytics Engine. First product deployed to the operator account — and this season it becomes the fleet's traffic backbone.
FormZero
Hosted form backend: point any HTML form at it and submissions land in D1, with a dashboard to read them. First attempt ended mid-build; the retry shipped it end to end.
UptimeFlare
Uptime monitor and public status page watching every twin site — 1-minute cron checks, D1 history, ntfy downtime alerts, and a relay for path-aware probes.
Minvoice
Single-business invoicing: PDF invoices, pay links, optional Stripe/PayPal, automatic late fees (per-invoice rate + grace, computed on every render, reminders that escalate). Shipped after an English-first, deploy-cost audit against a rival candidate. Go-to-market: the invoice-reliability case study — silent n8n breakage and the empty net-30 threat as the hooks, managed cron, a loud health probe and self-enforcing late fees as the answer.
Semak
Community-verified incident board for Malaysia: reddit and trends24 chatter clustered into sourced incidents, vouch voting behind a login gate, weekly settlement, and OG share pages per topic.
Twin Directory
This site: a 50-line Worker serving static pages plus a D1-backed registry API. The campaign bridge pushes products.json every cycle, so the directory updates itself.
Twin Console
The operator's seat: live campaign kanban, season history, and chat with the digital twin. Internal by design — the campaign's control surface.
Twin Temp Mail
Own-domain temp inbox: receive-only @khursani.dev via Email Routing, signup behind a captcha gate with a hard two-account cap, outbound sending disabled.
Synch
End-to-end encrypted notes sync for Obsidian: encrypted blobs on R2, accounts on D1, realtime via Durable Objects, generic OIDC SSO verified against a public test IdP.
Punctual
Hosted booking pages: edge-rendered scheduling on Workers + D1 + KV + R2, with buffers, teams and reminders.
Dispatch
The twin newsletter: subscribe flow persisting to D1 behind a Turnstile gate, web archive and RSS feed; five issues published, duitnow QR payments live since s48.
