I built a free PDF toolkit for internet cafés — need honest feedback

Samarth — Thu, 23 Apr 2026 09:32:36 +0000

Internet cafés handle a surprising amount of PDF work every day — merging documents, splitting files, converting formats, etc.

Most tools out there are either:

Paid
Too complex
Or not optimized for quick daily use

So I built a simple tool to solve this:
👉 https://pro-pdf-toolkit.onrender.com/

What it does:

Merge PDFs
Split PDFs
Convert files
Basic PDF utilities

Goal:
Keep it fast, simple, and actually useful for real café workflows.

I’m not here to promote it — I genuinely want feedback from people who might use something like this.

If you get a chance to try it, I’d love to know:

Does it actually help in real usage?
What feels missing or slow?
What would make it 10x better?

Your input will directly influence what I build next 🚀

🚀 Devs, would you actually use this?

We’re building a tool and need honest feedback 👇
💡 The Idea
Paste your website URL → get a complete performance breakdown:
⚡ Strengths (what you're doing right)
🐢 Weaknesses (what’s slowing you down)
🎯 Exact causes of performance issues
🛠️ Suggested fixes with code
🔥 Extra Features
🔍 Compare Mode → Your site vs competitor
🤖 Auto Suggestions → Where & what to improve
😈 Roast Mode → Brutally honest website feedback (for fun + insights)
❓ The Real Question

Would this actually help you as a developer?
Would you use something like this regularly?
What would make it 10x more useful?
Is “roast mode” useful or just gimmick?

🎯 Goal
We’re not building another generic audit tool.
We want something practical, dev-focused, and actually actionable.

Be brutally honest 👇
Your feedback will shape what we build.

LumosUI: Reducing Repetitive UI Work in Next.js Apps

Samarth — Tue, 21 Apr 2026 18:18:55 +0000

I built LumosUI out of frustration with the repetitive UI setup on every new project.

The library is built on Next.js + Framer Motion + Tailwind and includes ~20 advanced components (bento grids, spotlight cards, animated heroes, scroll-reveal primitives, magnetic interactions). Components are structured to be copied into existing projects without requiring LumosUI as an installed dependency.

The interesting part is the prompt system. The library ships with structured Claude AI prompts and skills designed to help developers scaffold landing pages and full frontends from a product description. The prompts are component-aware — they reference LumosUI components by name and generate layouts that map to the actual component API.

Technical stack: Next.js 14 App Router, Framer Motion 11, Tailwind CSS 3, TypeScript.

It's launching as a paid lifetime-access product ($25 for early users). I know some will object to paid developer tooling, so here's my reasoning: I want to keep it a focused, maintained library rather than an open-source project that gets 3 PRs and dies. Early adopters get all future components automatically.
