About glunty
Small browser tools that load fast and stay out of your way.
What this is
glunty is a growing collection of browser-based utilities. Each tool does one thing well, loads instantly, and works offline where possible. There are no sign-ups, no popups, no paywalls, and no third-party trackers. The catalog grows as new tools ship; see all tools for the current set.
Why this exists
Most online utility tools are buried under modals, paywalls, and ad placements that block you from doing the thing you came to do. glunty was built because that pattern is exhausting. The constraints are simple: tools must work above the fold without sign-up, must not rely on third-party tracking, and must not interrupt your task with surprises.
Principles
- One thing, well. Each tool does a single specific job. If a tool would benefit from a different feature, it goes in a sibling tool, not the same page.
- Browser-first. The default is "everything runs in your browser." AI-augmented tools that need a server are clearly labeled and explain what gets sent and where.
- No accounts. Nothing requires an email, phone, or sign-up. AI-augmented tools have a generous per-IP daily limit; that is the only rate-limit you will encounter.
- No popups. No modal asks for your email. No "subscribe to use this tool." No "log in for the full version." If a tool exists on glunty, it works fully.
- No tracking. No third-party scripts, no behavioral profiling, no fingerprinting. The privacy policy lays out exactly what is collected (almost nothing).
- Plain language. Disclaimers, error messages, and editorial content are written to be read once. No marketing copy.
How tools come to be
Most tools are pure-client: the work happens entirely in your browser. A few AI-augmented tools (regex explainer, code explainer, alt text generator, and others) send your input to Anthropic for processing and return the response; nothing is stored on the glunty side beyond the request. Each AI-augmented tool has a free daily limit to keep the service available without requiring sign-up.
How the site is built
The site is statically generated with Astro and deployed on Cloudflare Workers with Static Assets. There is no JavaScript framework on the front-end; tool interactivity is plain client-side scripts. Pages are prerendered to HTML at build time so the tool works the moment HTML loads, before any JavaScript runs. The AI endpoints under /api/ are server functions that proxy to the Anthropic API and apply per-IP rate limiting via Cloudflare KV.
Suggesting a tool
Have an idea for a tool that fits the catalog? Send it to hello@glunty.com. The criteria are simple: the tool should do one thing well, work in a browser, and not require ongoing infrastructure beyond the kind glunty already runs (Cloudflare Workers + KV + occasional Anthropic API calls).
Embedding and citation
Every tool page has an "Embed this tool" section that produces a copy-paste iframe snippet so the tool can run on third-party sites. Every tool page also has a "Cite this tool" section with five standard reference formats (URL, Markdown, BibTeX, APA, MLA) so the tool can be referenced in academic, journalistic, or technical writing without friction.
Feeds and discoverability
The catalog is available as RSS and as a sitemap. AI crawlers that read llms.txt get a brief site description plus links to featured tools. The robots.txt explicitly allows the major AI-search and traditional crawlers.
Compliance and policy
See Privacy Policy for what is collected (almost nothing) and Terms of Service for the rules. Both are in plain language and take under a minute to read.
