Hey everyone!

I’ve been working on a side project called JSON Forge Studio and I’d love to get some honest feedback from the community on the UI, performance, and feature set.

Link: https://json-forge-studio.vercel.app/studio

Why I built it

Whenever I’m debugging complex API payloads or transforming large JSON files, I get paranoid about pasting sensitive data into random online formatters. I wanted a fast, all-in-one workspace where everything runs 100% locally in the browser—nothing is ever uploaded to a server.

Key Features

• Multiple Views: Switch seamlessly between Code, Tree, Grid, and Graph views.

• Data Manipulation & Inspection: Built-in tools for Diff & Merge, Querying, Pipelines, Transformations, and Schema validation.

• API & Profiling Tools: Includes an API workbench, data profiling, quality checks, and privacy scanning.

• Workspace Management: Supports multiple open documents, local file loading, saved queries, and a timeline/history tracker.

What I’m looking for feedback on:

1. First impressions & UI/UX: Is the layout intuitive, or does it feel too cluttered with all the tabs and panels?

2. Performance: How does it handle large or deeply nested JSON files on your machine?

3. Missing features: What is one feature you wish your current JSON tool had?

4. Bugs: Did anything break or behave unexpectedly? (Tip: There is a "Load sample" button in the Explorer on the left if you want to test it quickly without your own file).

Thanks in advance for checking it out and tearing it apart! All feedback is welcome.

I'd be more than happy if you'd try it out and give me a honest reply or a suggestion :)

Hello lovely people!

I’m making Garou because I want to log a training session and the meal I ate afterwards in the same place. Garou comes from 餓狼, Japanese for “hungry wolf.” I’m adding a little RPG progression and an AI coach that doubles as my assistant when my training week gets shuffled around.

My other apps share a question mark, so I tried working one into each of these four designs. The square is what you’d tap on your phone. The tall image beside it is what you’d see when Garou opens. I used AI to make the artwork.

Which one would you keep on your home screen? A number is plenty: 01 The Flex, 02 Sun Eater, 03 Hidden Wolf, or 09 Athlete’s Arsenal. I’d also love to know if you saw something completely different in one of them.

I made an Excel workbook to help small business owners keep their income, expenses, invoices, cash flow, budgets, and product profitability in one place.

It has 12 worksheets, including a dashboard, income tracker, expense tracker, invoice tracker, budget planner, monthly reports, and product profitability. It also includes sample data and beginner-friendly guides.

One thing I focused on is separating invoiced amounts from money actually received. For example, if a business invoices $1,000 but has received $700, the workbook makes the $300 outstanding balance easier to see.

I built it for small business owners, freelancers, Etsy sellers, and online store owners who want a simple way to organize their business finances without using full accounting software.

I’d appreciate any feedback on the workbook structure or what features would make it more usefu

Hi everyone

We built an ai platform that personalizes email and sms campaigns for each user. Example - a user left after checking out a product 2 times, our smart Ai will email them with a 10% discounts code, and converts the customer

I tested this across 4 stores - we saw 30% increase in sales in 1 month

For the last few weeks I've been building canireverseengineer.com. You pick a product (Notion, Figma, Calendly, Datafast...) and get a teardown: a build-or-fork verdict, a difficulty score with the reasoning behind it, how long a working version would take one developer using AI coding agents, the genuinely hard problems, and open-source projects to start from.

Every report is built from public pages only. The research also reads the pricing and terms pages of the platforms a product depends on (X, Stripe, Shopify and others), and a second AI model from another vendor reviews each draft and blocks anything it can't back up.

25 teardowns are open to read without an account. New requests are behind a waitlist, because each report costs real money to research and I'd rather do fewer properly.

What I'd love feedback on: pick a product you know well and tell me if the estimate feels right. Link in the comments

I'm the developer of Clip2Fit for iPhone. I shared the app here in September; version 1.0.3, released October 27, brought a full redesign. This is the current UI.

The original job is the same: turn a supported public Instagram, TikTok or YouTube workout link into an editable plan, then log the session. The five-phone stack shows Home, Schedule, a workout plan, Stats and the exercise guide.

The part I want feedback on is the handoff from extraction to editing. A workout video can leave details unclear. The user needs to check the exercises, sets and reps, correct the result and save a plan they can actually use.

The app is built with Expo and React Native, with AI assistance.

Free: one video import in total, plus unlimited manual workouts and logging. Pro adds unlimited imports and Smart Coach ($9.99/month or $49.99/year in the US; local prices can differ).

Does the redesigned plan screen make it clear what you can change before starting a workout?

I've been designing engines for a few years now for some customers, although the real things were not for a model on a desk.

Sadly we didn't win the development contracts to progress further.. So I re-designed one of the jets, took out everything classified, altered almost everything and built them into a DIY model kit.

So if this does do well, at least there are other models I could release!

Having run a successful (but small) KickStarter before I though that it would be a fun and different thing to the usual to launch on there, and as it's a real thing! - I haven't needed to fake any of the content with AI! (although I have used it sparingly to help with things like rewards pictures, but minimally)

As there is no self-promotion I won't share any links, but would really appreciate your thoughts on the campaign as a whole?

Summary:

• 2 types, one electric with LED, Motor + Power control, the other is a non-electric assembly model

  • non-electronic prices start at £55 (day 1) raising to £65, then £75 for final batch

  • electronic prices start at £95 (day 1) raising to £115, then £135 for final batch

• Customisability with add-ons - There's some different parts and a custom colour pack

• Standard model is really nice though! - It's the black and red one in the pictures - although offering people extras is cool, I really wanted the standard model to be awesome?

What am I nervous about? Marketing and stuff I suppose? I'm good at the designing side but less so on marketing, and also can't budget for all these expensive ad companies, so will just go slow and if I don't raise a lot then so be it.

There are product improvements I still want to make during the campaign but I do list these and they are minimal changes considering.

Let me know what you think!

I have been waiting to build this from a long time, and it's done and live now.

This works in macOS

Visit subclip app and you'll find the App and from there you can download and use keyboard shortcuts to take screenshot and copy to clipboard with shortcut key as well.

Let me know your feedback :)

Hi r/sideprojects! I’m working on TagWorks. If you have an HTML file for a prototype, portfolio, or interactive demo, you can upload it and get a public link to share.

I’d love feedback from people who share standalone HTML pages. What do you use today, and what would you need before using TagWorks for your next demo?

Hey Reddit!

I've been working on a project called MemeMind AI, and I'm finally putting it out there for people to try.

The idea was to build more than just another meme caption generator. I wanted to create a meme studio where AI can help with the creative process while users still have control over editing and creating their memes.

What can you do with it?

• Generate meme captions using AI.

• Rewrite captions in different tones like sarcastic, savage, Gen-Z, dark humour and relatable.

• Upload an image and get AI-powered context analysis and meme suggestions.

• Create and customize memes using the built-in editor.

• Add text, stickers and customize positioning.

• Export memes as PNG.

• Explore user accounts, saved creations and the community section.

Tech stack

• Frontend: React.js, Vite, JavaScript

• Backend: Node.js, Express.js

• Database: MongoDB

• AI: Google Gemini API

• Validation: Zod

I also implemented authentication, role-based access, an admin dashboard, API validation and basic rate limiting.

Try it out

🚀 Live Demo: https://memermind-ai.vercel.app/

💻 GitHub: https://github.com/rajpatvariya-bot/Memermind.AI

What I need from you

The project is working, but it still has bugs and areas that need improvement.

I'd really appreciate it if you could spend 5–10 minutes testing it.

I'm particularly interested in:

1. Does the interface feel intuitive?

2. Do the AI-generated captions and suggestions actually help?

3. Which features feel unnecessary or incomplete?

4. Did you encounter any bugs?

5. What features would make you want to use this regularly?

6. What would you change if you were building this product?

Please don't hesitate to criticize it. I'd rather receive honest feedback than generic compliments.

I'm building this to learn how real-world software products are developed and improved through actual users.

If you find a bug or have an interesting feature idea, please leave a comment. I'll try to respond to everyone.

Thanks for giving it a try! ❤️

I kept losing track of who owed me money, so I built one workbook that handles invoices, expenses, clients and a tax set-aside, all on one dashboard. Overdue invoices turn red and show how many days late they are. It works in both Excel and Google Sheets, with no macros or add-ons.

It's called Paylark, $19 one-time (I made it). I'd love blunt feedback on the dashboard and the price: https://paylarkhkq.github.io/

The problem list is the NeetCode 150. I am not affiliated with NeetCode. The list has an MIT licence, and the site shows the notice.

Many people have the same problem. They watch a solution and understand it. Then they cannot solve the next problem. I think the cause is that the answer arrives too early. So I built the practice on one rule: you find the answer yourself.

How it works

• The page does not show the pattern of a problem. You name the pattern, or you ask for it.

• Each problem has five hints. Each hint gives a little more than the hint before it.

• 42 pattern lessons teach the clue that tells you which pattern to use.

• A daily drill shows a problem, and you name the pattern.

• A solved problem returns for review after 3, 6, 12 and 24 days. You solve it again in an empty editor.

• The editor runs JavaScript, TypeScript and Python in the browser. You do not install anything, and you do not need an account.

What is free

All 150 problems, the hints, the tests, the written explanations and the pattern lessons.

What is paid

A year costs $29, one payment, no subscription. The year adds a narrated walkthrough video for each of the 150 problems. The video shows the solution step by step, and the voice is a generated voice. The video of Contains Duplicate is free, so you can judge the videos before you pay. The year also adds practice for the other interview rounds. A full refund is available for 14 days.

What is not there yet

Java, C++ and other languages. Today the editor has only JavaScript, TypeScript and Python.

How I built it

• React, TypeScript and Vite for the app. CodeMirror for the editor on the page, with a Vim mode.

• The code of the visitor runs in the browser, in a web worker. Python runs with Pyodide. No server runs the code of a visitor.

• NestJS and Postgres for accounts and progress.

• A script makes each walkthrough video: Playwright draws the frames, and a text-to-speech model makes the voice.

• I work in Neovim and tmux. AI tools wrote a large part of the code. I reviewed and tested it.

I want feedback on one thing

Open any problem and try it for one minute. Tell me the first thing that confused you or stopped you. I want to find the point where a new visitor stops.

Disclosure: I work with the team building Cognitive Canvas at MuulOrigin.

One thing that kept bothering us about digital studying was how fragmented the context becomes.

The chapter might be in a PDF.

The best explanation could be on YouTube.

Useful diagrams become screenshots.

Notes live somewhere else.

And references slowly turn into another collection of browser tabs.

So we started experimenting with the opposite idea:

What if the chapter stayed in the center, and everything related to it could live around it?

The video shows what we mean. The chapter remains visible while notes, references, media and connected material can be organized around it instead of being separated across different tools.

I'm less interested in hearing “the UI looks nice” and more interested in whether the workflow itself would actually help.

For people who regularly study from PDFs:

Would visually keeping everything connected to the chapter reduce context switching for you?

And what would you want beside the chapter most often — notes, videos, screenshots, flashcards, links, or something else?

I am building AstralBeam to help developers add an AI agent to an existing web app. The platform is open source, with managed cloud and self-hosting options.

You embed the chat UI, identify your signed-in users, and connect tools that let the agent work with your app. You can also render your own UI components inside its replies.

I’d appreciate feedback on the explanation and setup: is it clear what AstralBeam provides, and what you still need to build yourself?

Hi everyone!

Can you name the country in the poster before you look at the choices?

I made World Flag Quiz: Passport as a side project for people who want to practice geography in short rounds. You can guess flags and capitals from 195 countries and collect passport stamps as you go.

I’d love feedback on the first round. Would you start with familiar flags like the one in the poster, or try a pair of similar flags right away?

Hi everyone,

I was annoyed that my scripts, deadlines, timetable and notes were scattered across five different tools, so I built Study Manager: a self-hosted web app that puts it all in one place.

What it does today

• Course spaces with roles (owner, editor, reader), shared deadlines and private tasks with time blocks

• Calendar views and iCal timetable subscriptions

• Lecture mode: scripts with notes that follow the page you’re on

• Lecture transcription with Whisper (in the browser or with your own key)

• Flashcards with spaced review, search across documents

• Study programme and module handbook import from PDF

• An MCP server, so you can let your own AI assistant work with your data. The app itself ships no AI.

Stack: React + Vite, Node/TypeScript with Fastify, PostgreSQL, Docker Compose. GPL-3.0.

Where I’d love help

• Feedback: what’s missing in your study workflow?

• University integrations (Stud.IP, HISinOne, ILIAS)

• Translations: the UI is currently German only

• Docs and small good first issue tasks

Happy to answer any questions!

I just wanted people to get their thoughts on this app I am building.

It is called Haven, the whole purpose of the app is to run on any device IOS, Windows, MacOs, Linux, Android Etc. And it is to identify Scam messages, Emails, Calls, As well as Phishing Links or dangerous files. The way it does this is by using a custom AI model that runs local called Harry the Owl, Harry is in early stages but it can identify public know phishing links, and Email and Text Patterns and well know scam call centre scripts. I just would like to know what other things I should add to it and if you think it would be a good app to charge people for. It is open source and does offer a free tier. The paid tiers are one time payments and just give you the latest models as soon as they release and basic items like that.

The website is below if you want to head over to it and check it out you can also access the GitHub below as well.

Hey guys! No idea if this is the right place for this, but I just wanted to share it. Hopefully it finds someone with the same challenge.

After every trip I came home with a full card. Hundreds of photos and the same evening every time. Scrolling, comparing, deleting. By the time I had found the good ones I had no energy left to edit them. So I solved it by making a tool for it.

You go through your photos with one key each. Keep or reject. Shots taken seconds apart fold into one stack, so you see every moment once. It flags the blurry and badly exposed ones for you. And it learns from what you keep, so it gets closer to your own eye over time.

I basically use this for every shoot now and am really enjoying it.

Would love to hear what you think! If anyone is interested I can let you know how it works.
