Show HN: Free Browser-Based Tools Client Side Only, No Uploads, No Tracking

#1

Post by axyz7732 »

I got tired of juggling 20+ tabs for basic utilities (JSON formatting, PDF merging, regex testing, image resizing, fake document generators, etc.), so I built a single, fully client-side hub with over 200 tools that run entirely in the browser. Key points:

Everything processes locally—no server uploads, no data leaves your device, no sign-ups, no ads, no tracking. Works offline after the initial load (progressive web app vibes). Categories include: Developer Tools (JSON/YAML/CSV/Regex/Base64/Epoch/etc.), PDF Tools (merge/split/compress/convert/extract), Image Tools (resize/compress/watermark remover/background remover/OCR), Encoding & Security, SEO & Network utilities, AI-assisted tools (e.g., ATS resume checker/roaster), Finance calculators (GST/salary/tax), Document & Fake Generators (resumes/invoices/fake chats/tickets/etc.), and more niche ones.

Built with plain HTML/JS/Canvas/WebAssembly where needed—lightweight, fast, mobile-friendly. Live here: https://tools.geeksprep.com/ Why share now:

Started as a personal productivity fix for devs/designers/job seekers in India (Bengaluru-based side project). Grew to 200+ tools via user requests and iterative additions. Privacy angle is core: In a world of upload-heavy "free" tools, this keeps your data yours.

Would love honest feedback from HN:

Which tools are actually useful (or broken)? Missing must-haves in dev/productivity space? Performance/edge cases on large files or specific browsers? Suggestions for better UX or new categories?

It's open for iteration—happy to add/fix based on real input. Thanks for checking it out! (Part of the broader GeeksPrep career prep platform, but this tools subdomain is 100% free/independent.)

I’ve found many useful tools here. Privacy really matters these days. A lot of products send user data to their servers, and we don’t always know how that data might be used. So I genuinely appreciate the idea of keeping everything client-side.

That said, I noticed you’ve put quite a bit of effort into blocking source view or browser inspection. I’d suggest reconsidering that. If everything truly runs in the browser, it would actually build more trust to let people verify that. Anyone can open the network tab and confirm that no data is being sent to a server.

I understand the concern about people copying your work. But realistically, with vibe coding, most of these tools can be rebuilt fairly quickly anyway. Trying to prevent copying at the browser level usually doesn’t add much protection.

Instead of focusing on blocking inspection, I’d suggest focusing on growing your user base and competing on quality. If you’re worried about code copying, lightweight obfuscation is probably a more practical solution than trying to disable developer tools.
