I got tired of juggling six extensions + DevTools just to inspect a page, so I built one that does it all locally

I do a lot of web and SEO work, and my browser had turned into a graveyard of single-purpose extensions — one for fonts, one for color picking, an SEO checker, a contrast checker, a tech-stack detector — plus DevTools open on the side. And half of them wanted permissions I didn't love.

So I built the one I actually wanted: A1 Multitool. Open the popup, pick a mode, and it inspects the current tab — locally, and only after you click.

What's in it:

- Type: hover-highlight any element to read its computed font, size, weight, spacing, color; lists every font on the page

- Color: sample colors, copy HEX/RGB/HSL, view the palette, check contrast

- SEO: indexability, title/description lengths, canonical + robots, OG/Twitter tags, JSON-LD, headings

- Links: internal vs external, nofollow usage, external domains

- HTML: duplicate IDs, empty attributes, missing alt/lang/title

- Accessibility: unlabeled inputs, nameless buttons, missing alt, heading skips, landmarks

- Performance: load milestones, request count, transfer size, largest resources, third-party hosts

- Tech stack: frameworks, analytics, ad tech, consent tools, CDNs

- Overlay: outline elements or hover to measure pixel sizes

The part I care most about: it runs entirely on-device. No page content, reports, browsing history, or settings get sent anywhere. Every check runs locally, on the current tab, after you click.

It's early and I'd genuinely like feedback — what's missing, what's clunky, and what you'd actually reach for day to day.

@RepJackKimble I like how this tweet uses “should not be allowed” and “it’s for freedom” at the same time.

[Bob @bobjones]

4 days no Codex and then a fkn reset on the day of my weekly reset. Whooptidoo.

[Bob @bobjones]

@Howaboua @thsottiaux It’s almost as if they do it on purpose

[Bob @bobjones]

@thsottiaux @jxnlco Rate limits

[Bob @bobjones]

Why does it feel like my $20 Plus plan got more Codex usage than the $100 plan last few weeks? Are we getting baited and switched?

[Bob @bobjones]

I thought GPT 5.5 Extra High could do anything.

[Bob @bobjones]

@ajambrosino Could have been a beautiful rate limit counter bar.

[Bob @bobjones]

@thsottiaux Never ran into weekly rate limits but now I’m at 0% until Sunday even after the last reset. Kinda bummed.

[Bob @bobjones]

@thsottiaux But we just ordered catering for our Thursday Codex drop party 😭

@jayair McDonald’s.

[Bob @bobjones]

Can’t believe we had 2 resets this week and I’m still at 0% on Codex until Sunday.

[Bob @bobjones]

@testingcatalog Can’t setup billing in Australia though.

[Bob @bobjones]

Why can’t we setup billing on OpenAI Ads in Australia? What was the point of inviting us in the first place? @sama @OpenAI

[Bob @bobjones]

@WesRoth Except in Australia we can’t seem to set up billing so we can’t use the ad account.

[Bob @bobjones]

My Codex plan hitting rate limits before Claude is wild 😭 this was not on my bingo card for 2026

[Bob @bobjones]

@rezoundous This was me an hour ago. Now I’m in bed staring at the ceiling until Sunday.
