Summary

Agent Relay Desktop ships Windows builds now, but the site had no download page, so Windows visitors had nowhere to get the app. This adds /download and detects the visitor's platform on the server so Windows users see the Windows build immediately.

What it does

  • Detects platform and architecture from the request's User-Agent plus the Sec-CH-UA-Platform / Sec-CH-UA-Arch client hints, in the server component, so the correct CTA is in the first response instead of swapping after hydration.
  • Skips phones, tablets, and ChromeOS; falls back to a plain "choose the download for your computer" state when the platform is ambiguous.
  • Links Windows x64/arm64 to AgentRelay-Windows-{x64,arm64}-Setup.exe, the per-user installer the v2026.10.55 release notes recommend. The portable .zip builds for both architectures sit beside it as the alternative.
  • Adds a first-run SmartScreen note for the unsigned Windows installer.
  • Lists macOS (dmg), Windows (exe, with portable zips), and Linux (deb, with tarball alternatives) under the recommendation, with the detected choice highlighted.
  • Adds /download to the sitemap, desktop/mobile nav, and the footer Products column.

All links use the releases/latest/download/ asset names from relay-desktop's release workflow, so new releases are served without a site deploy.

Architecture detection follows the machine, not the browser's emulation: Windows on Arm gets the Arm64 build, x64 Windows gets x64.

Testing

  • npm --workspace web run test -- lib/test/desktop-downloads.test.ts — 6/6 passing (detection precedence, mobile exclusion, installer/portable URL construction).
  • npx tsc --noEmit clean.
  • npm --workspace web run build succeeds; /download is a dynamic route.
  • Verified against next start:
    • Windows x64 UA → Download for Windows (x64) → AgentRelay-Windows-x64-Setup.exe
    • Windows x64 UA + Sec-CH-UA-Arch: "arm" → AgentRelay-Windows-arm64-Setup.exe
    • Mac UA → Download for macOS (Apple silicon) → dmg
    • Reduced UA with Sec-CH-UA-Platform: "Windows" → Windows CTA

Notes

  • Full npm run test still has pre-existing POSIX-shell/git failures on Windows; unrelated to this change and untouched.

Agent Relay Desktop ships Windows builds now, but the site had no
download page. This adds /download and detects the visitor's platform
from the request (User-Agent plus Sec-CH-UA-* hints) so Windows visitors
get the Windows build in the first response rather than after hydration.

Windows links point at the release zips, since the workflow publishes
AgentRelay-Windows-{x64,arm64}.zip rather than a standalone installer.
Windows users are told to unpack and run agent-relay.exe and warned
about the unsigned-binary SmartScreen prompt.

Also lists macOS and Linux options, adds tarball alternatives for Linux,
links to release checksums, and adds the route to the sitemap, nav, and
footer.

📝 Walkthrough

The change adds a responsive desktop download page for macOS, Windows, and Linux. It detects platforms and architectures from request headers, recommends a matching asset when possible, and adds navigation, footer, and sitemap links to the page.

Changes: Desktop downloads

Layer / File(s) Summary
Download catalog and detection
web/lib/desktop-downloads.ts, web/lib/test/desktop-downloads.test.ts
Adds download metadata and helpers for selecting assets by platform and architecture. Detection uses user-agent and client-hint data, with platform-specific defaults. Tests cover supported platforms, architecture selection, and unrecognized or mobile user agents.
Download page and presentation
web/app/download/page.tsx, web/app/download/download.module.css
Adds a request-aware page that recommends a detected download or prompts visitors to choose. The page shows platform assets, installation notes, Linux tarball alternatives, release information, and a Windows warning. Styles cover platform cards and responsive layouts.
Download page links
web/components/SiteNav.tsx, web/components/SiteFooter.tsx, web/app/sitemap.ts
Adds /download to desktop and mobile navigation, the Products footer column, and the static sitemap.

The page is broadly mergeable, but its Windows guidance should not recommend disabling system protection unless the installer is actually blocked.

A rabbit checks the headers bright,
Then finds the fitting file just right.
For Mac or Windows, Linux too,
A download waits with notes to view.
The page links shine across the site,
And cards resize to fit just right.

P2 Badge Request architecture hints before relying on them

For Chrome or Edge visitors on Intel Macs, this header will normally be absent: Sec-CH-UA-Arch requires server opt-in through Accept-CH, but neither the Next configuration nor the router requests it. Consequently, the Mac user agent falls through to the Apple-silicon default, making the primary CTA download a binary that cannot run on that computer; Windows Arm visitors similarly receive the x64 build. The tests supplying the header manually do not exercise this browser behavior. Request the architecture hint and use Critical-CH to obtain it on initial navigation, or avoid presenting an inferred architecture as detected. Microsoft’s client-hint documentation describes the required negotiation.

v2026.10.55 publishes AgentRelay-Windows-{x64,arm64}-Setup.exe, the
per-user installer the release notes recommend, so point the primary
Windows download at it. The zips stay as the portable alternative, matched
by the existing tarball treatment on the Linux card.

Make the Smart App Control instruction conditional.

The Windows note renders before any installer action and for every /download response. State what to do only if Smart App Control blocks the installer, and explain that disabling it reduces protection.
