Fixheader
Metadata repair for serious link previews
Fixheader audits a page's <head>, exposes what breaks rich previews,
and generates corrected metadata you can deploy fast. Built for operators who care about
iMessage, OG tags, and pages that unfurl the way they should.
$ fixheader https://example.com
status=200
issues=4
builder=Webflow
- Missing OG tag: og:site_name
- Duplicate OG tag: og:title
- Ordering issue detected
- og:image is not HTTPS
Corrected head ready to deploy.Why it matters
When a link preview looks broken, the page feels broken. Fixheader cleans up the part most teams never inspect.
Built for lean product teams
CLI-first and automation-friendly
Focused on preview quality, not generic SEO fluff
Preview proof
This is the story the product needs to tell in seconds: a shared link looks generic, low-trust, and unfinished before the fix, then becomes branded, clear, and clickable after it.
Take a look at the new page:
example.com
No branded image. Generic title. Missing context. Easy to ignore.
Now it looks launch-ready:
www.fixheader.com
Clear headline. Branded OG image. Immediate trust and context.
Use this in advertising
The before-and-after preview is not just a website section. It should be the backbone of your ads, demos, outbound messages, and launch content because it makes the value obvious without asking people to understand metadata first.
What it does
See missing Open Graph tags, duplicate metadata, ordering problems, and image issues in one report instead of manually digging through raw HTML.
Get a corrected <head> block and a corrected full HTML page so you can
ship a fix instead of just reading a warning.
Detects common builder interference, handles redirects, and keeps metadata close to the top of the document where scrapers are most likely to catch it.
Workflow
Point Fixheader at a page and fetch the live head metadata with redirect awareness.
Review missing tags, builder interference, media validation, and ordering problems.
Use the corrected head or full page output to patch the live site or deployment pipeline.
Who it is for
Audit client pages quickly and prove what is broken before launch or handoff.
Catch metadata problems before a launch post, DM share, or press mention falls flat.
Use JSON output and corrected HTML in QA, CI, or repeatable site-fix workflows.
Built for real operations
Fixheader is built around a practical workflow: inspect a URL, see what is broken, and generate corrected output you can actually ship.
Early users get direct support, a growing FAQ base, and product updates shaped by real metadata and preview problems.
The launch setup includes formal onboarding, support workflows, and a plan for licensing, billing, and international sales.
FAQ
No. It audits your page and generates corrected output you can deploy through your existing stack.
No. iMessage is a strong use case, but the metadata checks are useful for rich previews more broadly.
Not deeply. The goal is to translate head metadata problems into a report and corrected output you can use.
Yes. The CLI already supports JSON output and quiet mode, which makes it easier to plug into tooling.
Early access
The product is being shaped around real preview failures, fast support loops, and a simple operator workflow. If you want in early, this is the place to start.
