Omnitool — Web Developer Multi-tool

One launcher for the tools you keep reaching for while you build for the web. It all runs on your machine, and none of your browsing goes anywhere. Inspect - Tech stack: frameworks, CMS, analytics, server, CDN, and hosting for any page. Shows versions, flags outdated ones, infers the layers underneath, and can dump the raw signals it used. - SEO: meta tags, Open Graph, heading structure, links, and whether the page is indexable. - Fonts and colors: identify any font, pick any pixel. It keeps a history of your picks. - Request logger: watch the tab's requests as they happen. Modify - Header rules: add, rewrite, or strip request and response headers, per site. - Element zapper: click the junk on a page and it's gone. Custom CSS if you'd rather restyle the whole site. - Form filler: one click and the form is full of believable test data. - Video speed: hover controls and shortcuts on every video. Capture - Screenshots: full page or a selected area, with an editor for annotating before you export. - Screen recorder: tab recording with a webcam bubble and an auto-zoom camera that follows the action. Trim it, change speeds, add text. No watermark, nothing uploaded. Why you can trust it Omnitool was written from scratch after a popular extension turned out to be shipping malware. The ground rules: - No third-party code. Every line in the package was written for it. - No network calls. No analytics, no telemetry, no remote config. - Everything processes on your device. Captures and settings never leave it. - The privacy policy explains every permission in plain language. Free. No account, no upsell.
