File Viewer family — 13 fast, single-file, offline viewers: PDF, Word, Excel/ODS, PowerPoint, Publisher, EPUB, Markdown, HTML, data (JSON/YAML/CSV/XML/TOML), logs,
.emlemail, X.509 certificates, and images (down to TIFF, QOI & farbfeld). No build step, nothing uploaded — ever. Repos: file-viewer.us is the hub; each viewer lives in its own repo (pdf · docx · sheets · image · cert · …) -
TextWizard — browser-local text & code tools: case converters, diff, analyzers, and more. MIT, zero dependencies, nothing leaves the tab. Repo: textwizard-tools
-
Wizard apps & extensions — ResizeWizard (anchored browser-window resizing, live on the Chrome Web Store), CopyWizard (smart form mapper — copy form fields across sites with reusable profiles), and UploadWizard (white-label client file-upload SaaS: multi-tenant Astro SSR, custom domains, passwordless auth). Free + Pro tiers via Stripe.
-
IP Cow — privacy-first IP, DNS & email diagnostics, running since 2005. Rebuilt in 2026 as an Astro site + API on dedicated Hetzner hosts, with separate IPv4-only and IPv6-only probe endpoints. The reusable core is MIT: ipcow.com-tools (
@ipcow/tools-core+ipcow-probe). -
MyKK — a single-file browser start page with 10+ widgets (weather, stocks, RSS, calendar, bookmarks, ambient sounds, more). Vanilla JS, zero deps, Pro tier via Chrome extension + Stripe. Joined by favorites.mykk.us, a KV-backed speed-dial on Cloudflare Workers — free forever, with cross-device sync as Favorites Pro ($3/yr, 30-day trial) sold at favoritespage.us via Stripe + a better-auth license portal. Repos: mykk.us-dashboard · mykk.us · favorites.mykk.us
-
tgwab-web — pnpm + Astro 5 monorepo powering the identity fleet (hub, blog, dev portfolio, family, ham radio) from one shared design system (
@tgwab/design-tokens+@tgwab/ui). Cloudflare Pages, no Google Fonts. -
The estate — the ops layer behind all of the above: Cloudflare Workers and scheduled jobs for job-liveness alerting, uptime probes, notification relay (Discord + email, DMARC/TLS-RPT ingestion), and transactional mail, governed by a shared standards repo. Mostly private by design; the mail Worker is public: mailer.
