VibeHeader Pause Copy link Share headers like you share a doc
Three steps. No account, no files to send around.
Set up your headers
Add them in the popup. Toggle on or off anytime.
Send a link
One click copies a link that carries your whole setup.
They click “Use Now”
They preview the headers and apply them in one click.
Your headers are your business
VibeHeader is built so we couldn’t peek even if we wanted to.
Everything stays on your device
No servers. Your headers live in your browser — even share links are read on your side.
No ads, no tracking
Nothing watches you, nothing phones home. A tool, not a billboard.
Open source, so you don’t have to trust us
The code is public on GitHub — check the promises yourself.
Sources: RFC 3986 §3.5 — URI fragments · MDN — URI fragment (“The fragment is not sent to the server when the URI is requested”)

Why people switch
“It quietly replaced ModHeader for me. I copy a share link, drop it in Slack, and the PM has my exact setup — no more ‘can you screenshot your headers?’”
Fnng · Full-stack Engineer
“Engineers made me install ModHeader just to sign off on tests, and it kept popping ads at me. VibeHeader does one job, does it quietly, and stays out of my way.”

Familiar workflows. Most people finish in about five minutes.
Common questions
Is it free?
Yes — free, no paid tier, no ads. It’s open source, so it stays that way.
Can you see my headers or my browsing?
No. Everything stays in your browser — no servers, no analytics.
Are share links safe to send?
Yes. Links are read only on the receiver’s device, and sensitive values are masked in the preview. The config travels after the # in the URL — a part browsers never send to any server.
I’m switching from ModHeader — is it hard?
No — the basics work the same. Five minutes with the migration guide.
Is VibeHeader a good ModHeader alternative?
That’s what it was built to be — the core workflows feel familiar, minus the ads and tracking. See the side-by-side comparison.
Is VibeHeader open source?
Yes — MIT-licensed, with the full source on GitHub.
Which browsers does VibeHeader support?
Chrome and Edge — any Chromium-based browser. Built on Manifest V3.
Do I need an account?
No. There’s nothing to sign up for — install it and start.
