No way to visualize API response changes across different versions during development
When building APIs, I constantly need to compare how response structures change between versions. For example, v1 returns user data one way, v2 restructures it, and v3 adds new fields. The problem: There's no visual diff tool specifically for API responses. I'm manually copying JSON responses into text diff tools, but they're optimized for code, not nested data structures. Changes to deeply nested objects are nearly impossible to spot. What I'm trying to accomplish: Catch breaking changes before they hit production. Last week I shipped an API update that renamed "user_id" to "userId" in a nested object 4 levels deep. It broke 3 client applications because I didn't catch it in testing. Current workaround: I paste responses into VS Code's diff viewer or online JSON diff tools. Neither highlights the actual impact - like "this field moved" or "this array structure changed" in a developer-friendly way. Who else faces this: Any backend developer maintaining versioned APIs, especially when working with mobile apps that can't force-update immediately. Why existing solutions fail: - Generic diff tools show character changes, not semantic changes - Postman can compare, but only side-by-side text - No tool shows "Field X moved from here to there" or "This will break clients expecting array format" I need something like Git's diff view but understanding JSON structure, not just text. Should show moved fields, type changes (string→number), and flag potential breaking changes.
No simple tool for tracking client payments and sending automated reminders
I'm a freelance developer working with 8-12 clients at any given time. Each client has different payment schedules - some monthly, some per-project, some milestone-based. The problem: I'm constantly checking spreadsheets to see who hasn't paid, manually sending "friendly reminder" emails, and losing track of overdue invoices. Last month I forgot to follow up on a $3,200 invoice for almost 3 weeks. Current workaround: I use Google Sheets with color coding (green=paid, yellow=pending, red=overdue) and set manual calendar reminders to send emails. It's exhausting and error-prone. What I need: Something dead simple where I can log "Client X owes $Y by Date Z" and it automatically sends reminders at 7 days before, day of, and 3/7/14 days after. Just email reminders, not a full invoicing suite. Existing solutions don't work because: - FreshBooks/QuickBooks are overkill (I don't need accounting, just tracking) - They're expensive ($15-30/month for features I won't use) - Most require clients to create accounts or use their portal I just want a lightweight tracker that keeps me organized and reminds forgetful clients. Why doesn't this exist as a $5/month simple tool?
Figma has no built-in way to track design system component usage across files
I manage a design system used across 40+ Figma files by a team of 8 designers. We have 200+ components (buttons, cards, modals, etc.). The problem: I have no idea which components are actually being used and which are dead weight. Are designers using the new button variants or still creating custom ones? Is anyone using that complex table component I spent 2 weeks perfecting? What I'm trying to do: Clean up the design system and prioritize updates based on actual usage. But I can't make data-driven decisions because Figma doesn't show "this component is used in 47 instances across 12 files" vs "this component has never been used." Current workaround: Manually searching for component instances file by file. It's impossible with 40+ files. I've tried asking designers in Slack "do you use Component X?" but memories are unreliable. Why this matters: Our design system file is bloated. Loading times are slow. New designers are overwhelmed by 200+ components when maybe only 80 are actively used. I want to archive unused components and focus maintenance on what matters. Who else faces this: Any design team with a component library bigger than 50 components or used across multiple files/projects. Existing plugins don't solve this because they only work within a single file, not across an entire workspace. I need workspace-level analytics showing "Button/Primary is used 340 times across 23 files, Button/Ghost is used 4 times in 2 files." This should be a native Figma feature or at least a Figma plugin with workspace access.
Class notes end up scattered across too many apps and formats
During lectures, I take notes in different ways depending on the situation: handwritten notes, typed documents, photos of the board, or quick voice notes. Over time, these notes get scattered across multiple apps and folders. When exam time comes, it becomes hard to find all notes related to a single topic. Even when I know I wrote something down, I often don’t remember where or in what format. Existing note-taking apps are powerful but assume a single input method. There is no simple way to unify notes from different sources into one clear, searchable structure per course.
Important information in student group chats gets lost too easily
Group chats are widely used by students to share important information such as deadlines, exam details, and resources. However, these chats quickly become cluttered with unrelated messages, making it very difficult to find critical information later. Even when messages are pinned, they often lack context or are forgotten over time. New members joining the group usually have no idea where to start or what is important. There is no structured way to turn these conversations into organized, long-term information that everyone can easily access when needed.
Getting design feedback is chaotic and scattered
As a product designer, I share Figma prototypes with 10+ stakeholders. Feedback comes through: - Figma comments - Slack DMs - Email threads - Zoom call notes - WhatsApp messages I waste hours consolidating everything into one doc. By the time I'm done, people have already moved on. Existing tools like Loom or Marker.io are for bug reports, not design feedback. UserTesting is $100+/month overkill. I need: Share prototype link → Stakeholders click areas and leave comments → All feedback in one organized view with priorities.
Comparing similar apps is a nightmare
When I need to pick a new SaaS tool (project management, CRM, etc), I open 20+ tabs comparing features, pricing, and reviews across: - Product Hunt - G2 - Capterra - Reddit threads - Individual product websites Then I copy-paste everything into a Notion table. Takes 3-4 hours. Existing tools either: - Only compare 2-3 tools at once - Focus on one category (only CRMs, only email tools) - Don't include real user complaints from Reddit/HN I want: Paste 5 tool names → See side-by-side comparison with pricing, features, and aggregated reviews in one page.
Creating a realistic study plan that actually adapts over time is very difficult
As a student, I often try to create study plans at the beginning of a semester or before exams. At first, the plan looks perfect on paper, but as soon as real life happens — unexpected assignments, quizzes, or personal issues — the plan becomes outdated. Most study planners assume a fixed schedule and do not adapt when I fall behind or need to reprioritize topics. Updating the plan manually takes time and effort, so I usually abandon it altogether. What I need is a flexible system that adjusts based on progress, deadlines, and available time, instead of forcing me to constantly redesign my plan from scratch.
Studying progress tracking tool
During my IBDP years, this was one of the most frustrating problems I have faced. There was no automated way to track my progress when studying: I would solve some tests and questions, but it was hard to just chart how fast I was learning. Hence, I propose an app which shows you statistics of how much you’ve studided, what you’ve studied and your progress in each of the subjects. I think that would be great. I have seen some of them being done but either they’re quite expensive or they are some AI-based crap.
I capture ideas constantly but lose them when they matter most
I write down ideas, notes, and insights all the time. During classes, conversations, reading, or random moments of inspiration. Capturing information is easy, but making use of it later is the real problem. When I actually need an idea or a piece of information, I remember that I wrote it somewhere, but not where. Searching through notes becomes a frustrating guessing game. Most note-taking tools help with organization only if you are extremely disciplined. I want a system that helps me rediscover useful thoughts without needing perfect structure.
It is hard to keep track of unused subscriptions
Over time, I subscribe to many digital services and tools. I often forget about them until I notice repeated charges on my bank statement. Banking apps show transactions but do not explain what each subscription is for or whether I still use it. Reviewing everything manually is tedious. Most subscription management tools are either too complex or designed for heavy financial tracking. I need a simple overview that helps everyday users understand and manage recurring payments.
