A look at every Toolumen tool that’s live today, the ones in active development, and the ideas we’re still weighing. Requests move things up the list — tell us what you need.
Tools you can open and use right now — most run entirely in your browser.
Paste a URL, get a graded report on title, meta, canonical, OG, JSON-LD, h1, robots, sitemap, and llms.txt.
Open tool LiveSee your link the way Slack, iMessage, Twitter, LinkedIn, Discord, and Google would render it.
Open tool LiveForm-driven schema.org markup for Organization, LocalBusiness, Article, Product, FAQ, and Breadcrumb — copy-paste ready.
Open tool LivePull every JSON-LD block from a page and check each entity against schema.org and Google rich-result rules.

Open tool LiveGrade a URL’s HSTS, CSP, X-Frame-Options, Referrer-Policy and more, with the exact fix for each gap.

Generate crawler files pre-wired with GPTBot, ClaudeBot, PerplexityBot, and Google-Extended allow rules.
Trace redirect chains, catch loops and 404s, and flag mixed content across a URL.
Ideas we are weighing. Nothing here is committed — order and scope will shift as requests come in.
Fill a form, get the full head snippet with a live search + social preview — the inverse of OG Preview.
Responsive typography from a min/max size and viewport range — copy-paste CSS clamp().
Build tagged campaign URLs with saved presets — all client-side, nothing stored.
Encode and decode text to Base64 and inline data-URIs — all client-side, nothing uploaded.
We build the utilities Stacklumen reaches for on real client work first — that’s why the shipped tools lean SEO, accessibility, and Webflow. Everything else is shaped by what you ask for. A tool that several people request jumps the queue, and an exploratory idea nobody needs quietly drops off it.
Want to nudge something up the list? Send a request — it’s the single biggest signal we use.
Tell us what you’re missing. The best ideas come straight from people building on the web — and requests are how things move from “exploring” to “live.”
