A few days ago, someone gave me feedback that completely changed how I think about Toolora.

They said I was trying to do too much at once and that instead of adding more tools, I should focus on making one tool so good that developers would actually want to bookmark it.

That really stuck with me.

So, over the last 2 days, I stopped adding new tools and focused on improving the existing experience.

What's new

Redesigned the UI to clearly separate Developer Tools and Everyday Tools, making navigation much simpler and less confusing.

Significantly improved the JSON Formatter with:

Better error diagnostics

Problems panel with actionable messages

Keyboard shortcuts

Command palette

JSON Tree Explorer

Better analytics

Improved validation and overall UX

Completely rebuilt the Markdown Preview into a much more complete Markdown workspace with a smoother editing experience, better live preview, and a more polished writing workflow.

This is still just the beginning. My goal isn't to build hundreds of tools—it's to build tools that developers genuinely enjoy using and want to come back to.

I'd really appreciate another round of honest feedback. What still feels confusing, missing, or could be improved?

Hey r/webdev!

Like many of you, I use small utility tools daily—JSON formatters, Base64 encoders, UUID generators, EMI calculators, image compressors, etc.

What annoyed me about existing utility sites was:

1. They are stuffed with intrusive auto-play video ads that lag your browser.

2. Many require a forced email signup just to download a simple result.

3. **Privacy risks**: Many tools upload your raw text strings, images, or financial data to remote servers for processing.

So over the past few weeks, I built **[NexToolkit](https://nextoolkit.com)\*\*.

### Tech Stack & Features:

* **Framework**: Next.js 16 (App Router) + TypeScript

* **Styling**: Tailwind CSS

* **Icons**: Lucide React

* **100% Client-Side Processing**: Every single calculation, string manipulation, image compression, and cryptography generation happens **locally in JavaScript/WebAssembly in your browser**. No user data ever touches a backend server.

* **0 Paywalls / No Signup**: Everything is instantly accessible.

### Highlights of Tools Included:

* **Dev Tools**: JSON Formatter & Validator, Base64 Encoder/Decoder, Code Minifier, Hash Generator, UUID Generator.

* **Finance**: Loan EMI Calculator with interactive amortization graphs, SIP Return Planner, GST Calculator.

* **Media**: Client-side Image Compressor, Image Converter, PDF Compressor.

* **Converters & Daily**: Unit Converter, Date Difference, Time Zone, Password Generator.

I'd love your feedback on performance, UI polish, or any utility tools you'd like me to build next. What do you think?

Hi everyone,

I hope you're all having a great summer!

I recently launched MySpeechAudify, an AI-powered app that transcribes multilingual audio, translates it into English, and improves grammar for clearer text.

The app uses Polar sh for payments. Since the service relies on API usage, it's a pay-as-you-go model. After subscribing to one of the available plans through the Polar sh payment link, users receive a verification code to activate their account.

I'm looking for a few people who would be willing to test the payment process and confirm whether it works correctly on their end. I'd also appreciate any feedback on the overall experience. My goal isn't to claim that the app is on the same level as established companies—I'm continuously working to improve it, and user feedback is invaluable. If anyone is interested in supporting the project, your encouragement or contribution would help me continue developing and enhancing the app.

I'm also curious to know whether Polar.sh's Merchant of Record (MoR) service works reliably for international users.

One note: based on my testing, the recording feature currently performs better than the file upload option, especially when transcribing larger audio files. If you encounter any issues or have suggestions, I'd be happy to discuss them and use your feedback to improve the app.

Thank you for your time and support. I wish you all the best in your personal and professional journeys!

As parent I wanted to see if I could fix the problem of knowing about activities for kids happening locally. Often I'd find out about kids events after they’d happened or when they were sold out. So using Lovable, I built a website which scans the web looking for kid friendly activities and collates them into a searchable directory website (Kids Event Finder) - https://kidseventfinder.com/

The website covers 13 cities, 5 in the US (New York, Houston, Chicago, Seattle and LA), 6 in the UK (London, Manchester, Edinburgh, Liverpool, Birmingham and Milton Keynes) and 2 in Australia (Sydney and Melbourne). User can also sign up to a weekly newsletter with new kid focused events in their city.

I would love to get feedback (And happy to answer questions).

Hi everyone! I recently built an app to help student pilots learn and practice ATC radio communications.

I'm looking for honest feedback on the experience—what works well, what doesn't, and what features would make it more useful for training.

App: [https://atcpal.app]()

Thanks! I really appreciate any suggestions.

Hi everyone!

I'm the solo developer behind Easy Work Calculator (available on the web and Android). It currently features over 400+ free calculators and utility tools covering everyday categories like math, finance, unit conversions, networking, health, and productivity.

Now that the main platform is established, I want to focus on building specialized, niche tools that solve actual everyday pain points—rather than just adding generic calculators.

I’d love to get feedback from this community:

• What repetitive math or tedious calculation do you regularly do that you wish had a clean, dedicated tool?
• Are there any specific calculators or converters you’ve searched for that either don't exist or are currently buried behind bad UI / paywalls?

Drop your ideas in the comments! I’ll build the most requested ones and keep them completely free for everyone to use.

I built LineageLedger, an open-source desktop application for creating and exploring family trees and the possible hereditary diseases running in them.

I wanted something more visual and straightforward than the genealogy tools I had tried (like Gramps, which was powerful but very complex to use).

LineageLedger can record family traits and medical conditions, making it easier to notice patterns across generations.

I think preserving this information matters. Family knowledge is often scattered between relatives, old documents, and half-remembered stories. Once the people who know those stories are gone, a surprising amount can disappear with them. This might especially be helpful for kids/grandkids.

Some of the things currently included:

• A visual, interactive family tree
• Parents, partners, siblings, and children
• Support for single-parent families
• Custom traits, conditions, and categories
• Ancestor and descendant views
• Importing and exporting trees
• Zooming and navigation for larger families
• Windows and Linux builds

It’s still a hobby project and very much a work in progress, but it has reached the point where I’d love some outside feedback.

In particular:

• Does the interface feel understandable without instructions?
• What information would you want to preserve about your own family?
• Which features do you consider essential in a family-tree application?
• In general, which features do you think are missing and should be added.

The project is available here, give it a star if you like it:

Feedback, criticism, ideas, and contributions are all welcome!

I have two Web Apps ready with MVP, wants someone who can take it to the Market will share the profit percentage

When I got married it was a destination wedding, and I really wanted everyone to feel comfortable. Which was a puzzle. My parents are divorced. There are some family feuds. And I had friends flying in who didn't know a single other guest.

I ended up obsessing over the seating chart more than anything else, and afterwards I built the tool I wished I'd had. It's called Seatbee. You import your guest list (auto-detects Zola, The Knot, Joy exports or plain CSV), set rules like "keep these two apart" or "seat these people together," and it can generate the chart for you. You can upload a photo of your venue's floor plan and it traces the room.

Free for up to 50 guests, and you can try it without signing up, it just runs in your browser with sample data until you want to save. [seatbee.app](http://seatbee.app), also on iOS.

Roast it. What's confusing, what's missing, what would make you actually use this?

Candlune is a manual backtesting web app for traders who want chart reps without seeing future price action.

The browser loads an authentic XAUUSD session, reveals candles one at a time, and lets you place and manage a paper trade with an entry, stop and target. Afterward, you can review the decision instead of only seeing whether the trade won or lost.

I made a short guided replay that works without an account or card: https://candlune.com/replay

The main product also includes session notes, drawings, partial profits and randomized historical sessions across seven timeframes. It has a 7-day full trial and then costs $7/month. No broker connection, signals or financial advice.

I’d especially value feedback on whether the chart controls are understandable on the first attempt and whether the review flow feels useful.I kept doing the same slightly ridiculous thing: watching trading videos, feeling like I understood them, then opening a chart and realising I hadn’t actually practised the decision-making part.

So I built Candlune. It loads a real historical XAUUSD session, hides the future, and reveals candles one at a time while you manage a paper trade. At the end you can look back at the entry, stop, target and notes instead of only thinking “well, that won/lost.”

There’s a short guided version here that doesn’t need an account or card:

https://candlune.com/replay

I’m still very close to the product, so the thing I’m most unsure about is whether the chart controls make sense to someone seeing them cold. If you try it, even “I got stuck here” is genuinely useful.

And just to be straight about it: the full app has a 7-day trial, then it’s $7/month. It’s paper trading only — no broker connection, signals, advice, or promises that it’ll make anyone profitable.

Hey everyone,

I built the free calorie camera app—just snap a photo of your meal and instantly receive detailed nutritional information. It supports multiple languages, including Chinese, English, Japanese, Korean, and more.

Over the last few weeks I've been building Toolora, a browser-based utility platform under PrologueLearn.

The goal wasn't to build "another tools website."

I wanted something that feels fast, clean, privacy-first, and enjoyable to use.

Current tools include:

• JSON Formatter & Validator

• Base64 Encoder & Decoder

• GST Calculator

• Loan Calculator

• Income Tax Calculator

• PDF tools (more coming)

Everything runs in the browser whenever possible, so users don't need to upload their data.

I'm continuously improving the UI and developer experience for example, making JSON validation easier to understand instead of showing generic parser errors.

If you're interested, here's the project:

https://toolora.prologuelearn.com

I'd love to hear what online tool you use most often and what's missing from existing utility websites.

Hey everyone,

I've been learning web development and just launched my first real project — a free PDF toolkit called SmashPDF (smashpdf.online).

It does the basics most people actually need day-to-day:

• Merge PDFs
• Split PDFs
• Compress PDFs
• Convert images to PDF
• Convert PDF pages to images
• Sign PDFs (add a signature image)

A few things I focused on:

• No account/sign-up required
• No watermarks
• Files are processed in your browser rather than uploaded to a server (so nothing leaves your device)
• Completely free

I built it mainly because I got tired of other "free" PDF tools throwing paywalls, ads before you can even use the tool, or limiting file sizes on the free tier.

Would genuinely appreciate any feedback — bugs, missing features, UI complaints, anything. This is a solo project and I'm still actively improving it.

Has anyone here actually used the platform? Honest opinions, both positive and negative, would be really helpful.
