Case study · Open-source project site · Worldwide
The website for PowerDNS-AuthAdmin, a free, open-source web interface for PowerDNS Authoritative DNS built by its community of contributors. NGN built the site: four pages that answer the searches DNS operators make, show the real product, and practise what the project preaches.
PowerDNS-AuthAdmin had a single hand-written landing page. DNS operators look for a PowerDNS web interface in a few predictable ways: "PowerDNS admin UI", "PowerDNS-Admin alternative", or a feature they need, such as single sign-on or role-based access.
The project's values had to show in the site itself: no telemetry, no CDN, fast, and simple for any contributor to build. Every claim had to come from the app's own README, docs or changelog, with the version number set in exactly one place.
The app has a built-in MCP server, so its audience already uses AI assistants. The site had to be easy for them to quote accurately.
The palette comes from the logo, a monospaced wordmark with blue braces and a green "Auth", and nothing else. A developer tool lives in terminals and dashboards, so the site is dark first, with a light theme that is a full equal.

Body text in the light theme Blue as text uses its own tones per theme (#6fa8ff on dark, #1d5fd6 on light) so links pass contrast in both, and contrast is checked in both themes.
Everything readable
Inter
Weights 400 to 800, subset to the glyphs the site uses: 28 KB. Preloaded, with a metric-matched Arial fallback so a late font can never reflow the big headings.
Code, commands, versions
JetBrains Mono
For the quickstart, version tags and the monospaced accents that echo the logo. Subset to 14 KB.
An early version measured a layout shift of 0.10 on the comparison page from a late-loading font. The metric-matched fallback is why it is now zero.
A release pill linking to the latest version, the headline, the MCP section, a feature grid, integrations, a screenshot showcase, the Docker Compose quickstart, a short FAQ and a closing call to action.
One long catalogue: access control, sign-in, zone editing, MCP, topologies, DNSSEC and TSIG, audit, operations and accessibility.
The PowerDNS-Admin page covers what to look for in a PowerDNS web UI, how to move across, and whether it is the right fit. It is not a hit piece.
Every screen captured in light and dark, on desktop and phone, as responsive WebP with fixed dimensions. The set that matches the visitor's theme is the one shown.
A tiny inline script, allowed by a CSP hash, sets the theme before first paint. It follows the operating system until the visitor chooses, and remembers the choice.
Showcase tabs with arrow-key navigation, a lightbox with keyboard and swipe, live labels on the theme toggle, and visible focus throughout.
Plain HTML, CSS and a little vanilla JavaScript, generated by a zero-dependency Node script. Any contributor can clone the repository and build it in seconds, and it serves from any static host.
Version, release date, licence, supported PowerDNS versions and links live in one file. A release updates the hero pill, the footer, the structured data, llms.txt and the security.txt expiry together.
The feature catalogue and FAQs are structured content, each item backed by the app's own documentation.
Fingerprinted assets with long-lived caching and pre-compression, subset fonts, and logos for the inactive theme loaded lazily.
A Content Security Policy on every page with hashed inline scripts. The only third-party request is analytics, which the footer discloses with an opt-out.
A static checker tests titles, descriptions, links, structured data and the security policy, plus HTML validation, on every push and before every deploy.
The website's own source is public alongside the app's, so everything on this page can be checked.
Each page targets a search DNS operators actually make, and the structured data describes the software precisely.
SoftwareApplication and SoftwareSourceCode on the home page carry the version, licence, repository and platform, updated with every release.
The comparison page is written for people searching for an alternative to PowerDNS-Admin, and titles across the site are built around "PowerDNS admin UI" searches.
Supported PowerDNS versions, install, databases, single sign-on, passkeys, per-customer zone access, clusters, the API, MCP and telemetry, each written to be quoted out of context.
What it is, the latest version, the PowerDNS versions tested, the MCP tools it exposes and "no telemetry, no CDN; works air-gapped", with robots.txt naming the AI crawlers.

}Lighthouse figures: mobile, live home page, measured 19 October 2026 (a single run; scores vary slightly between runs).
It is a small, content-led site, and plain HTML generated by a zero-dependency script gives contributors nothing to install and visitors almost nothing to download. The home page scores 100 in all four Lighthouse categories on mobile and transfers about 280 KB.
The version, release date and supported PowerDNS versions are set once. The hero pill, footer, structured data, llms.txt and security.txt all read from that value, so a release means changing one line, rebuilding and redeploying.
Many operators find the project by searching for an alternative to PowerDNS-Admin, so that page answers the question directly: what each does, what to look for in a PowerDNS web UI, and how to move across. It is written as a fair guide, so it is worth quoting.
Every screen was captured in both themes, and the site shows the set that matches the current theme, which is set before the page paints. The screenshots are served as responsive WebP with fixed dimensions, so switching theme or loading on a phone never shifts the layout.
NGN built the website. PowerDNS-AuthAdmin itself is an independent, MIT-licensed community project by The PowerDNS-AuthAdmin Contributors, and every claim on the website is taken from the app's own README, documentation and changelog.
Italian deli & cafe · Narraweena
A first website for Rose's Continental Deli, in Narraweena since 1995: its navy and gold logo redrawn as vectors, a map drawn from OpenStreetMap in the brand colours, live Google reviews, and one structured-data entity that matches its Google profile.
Wedding & event florist · Sydney
A photo-led single page for a Sydney wedding and event florist: an Instagram archive turned into a full-screen hero with phone-specific crops, collages that quietly swap photos, and a call-or-text dock in thumb reach.
Mobile detailing · Northern Rivers
A Squarespace site rebuilt from the ground up: every ranking URL kept, a night-sky design taken from the owner's emblem, customer videos self-hosted with transcripts, and a "text a photo" button that turns a phone into a quote request.
