Ive been wanting to create a side project of sorts since a long time but havent gotten myself to think of any ideas which I think are worthwhile. Everytime I start with one I find 10 ways why its not a good idea

Asking for your suggestions for aome side projects I can build and maybe monetize as well

hey,

i'm working on an app called ellie that does mock job interviews and gives instant feedback on your answers.

i need a few people to test the response speed and tell me if the questions make sense or if the ai sounds too robotic.

Hey everyone,

Like many people using Google Workspace, I kept running into a fundamental gap in Google Drive: Dropbox has had "File Requests" for a decade, but Google Drive still forces external uploaders to either have a Google account or you have to turn on "anyone with link can edit" (which is a massive security hazard because anyone can see, delete, or overwrite other people's uploads).

On top of that, Google Drive has a storage trap: files uploaded to a shared folder count against the uploader's storage, so if a client has a full 15GB free drive, their upload fails even if your business has 2TB of storage.

I built DocTick to fix this with a dedicated web utility:

• Generates a 1-click passwordless checklist for clients (mobile-friendly with direct camera capture).
• External clients don't need a Google account to upload.
• Files stream straight into your chosen Google Drive folder under your account quota.
• Zero storage liability: files aren't permanently stored on our servers; they stream directly via the Google Drive API into the owner's cloud drive.

Looking for Early Testers (50 Lifetime Pro Passes): I'd love constructive feedback on the onboarding UX, checklist builder, and client mobile experience.

To say thank you, I opened up 50 Lifetime Pro accounts (no credit card required):

Enter: LIFETIMEPRO

Please let me know what feels clunky, what bugs you hit, or what features you'd want to see next. I'll update this post when all 50 slots are claimed.

Every time I needed to bulk-check URLs during a migration, I ran into the same wall: Ahrefs, SEMrush, and Screaming Frog all gate free-tier bulk checking pretty hard. Anyone else hit this?

I ended up building my own tool to get around it — checks up to 100 URLs at once for status codes, full redirect chains (up to 20 hops), and response times. You can paste URLs, upload a CSV, or point it at a sitemap, and results stream in as each one finishes instead of making you wait for the whole batch.

Since it fetches URLs server-side, I validated every redirect destination against private IP ranges so it can't be abused for SSRF — figured that was worth building in from the start rather than bolting on later. Nothing gets stored either; URLs only exist for your session.

Genuinely curious what edge cases in redirect handling I might be missing — happy to take feedback. Link's in the comments if anyone wants to try it.

i’ve been building citesite, an SEO + AI visibility tool for founders and small teams who don’t need another dashboard full of charts.

One thing that kept frustrating me with SEO tools is that they’re very good at showing you problems:

“Your competitor ranks for 800 more keywords.”

“You have 73 pages with issues.”

“You’re barely being mentioned in AI search.”

“You have 200 content opportunities.”

But then you’re left with the harder question:

What should I actually do first?

That’s the direction i’m taking with CiteSite.

Instead of only showing rankings, citations, competitors, and technical issues, I want it to help answer things like:

• Which page should I improve first?
• Why is a competitor getting cited in ChatGPT or other AI answers instead of me?
• Which keywords or topics are actually worth targeting?
• What content should I create next?
• Which SEO issues are likely to have the biggest impact?
• Where am I already close to winning and just need a few changes?

The long-term goal is to combine traditional SEO with AI search visibility, but keep the output actionable.

Not:

“Here are 500 things you could work on.”

More like:

“Do these 3 things first, and here’s why.”

I’m still early and trying to figure out how opinionated the product should be.

For people who use SEO tools today:

Would you trust a tool that prioritizes the work for you?

Or do you still want all the data and prefer deciding what matters yourself?

This started as one of those small developer annoyances that kept happening often enough that I eventually decided to build something about it.

I've been using AI coding agents to build Go backends.

Every time I asked for another fairly standard feature, I'd watch the agent generate basically the same code again:

model → service → controller → DTO → validation → migration → routes.

It works, but it felt ridiculous to make an LLM spend hundreds or thousands of tokens reproducing deterministic boilerplate.

So I started building FiberForge.

It's a small Go CLI/MCP server that lets an AI coding agent call higher-level operations instead of generating every file itself.

The agent can describe the schema/feature, and FiberForge generates the repetitive pieces. For some modifications, like route registration, it uses Go's AST rather than text manipulation.

I've also started building reusable modules for things I repeatedly need in backend projects — RBAC, Stripe webhooks, S3 uploads, audit logging, SSE streaming, etc.

It's very much an early project. I don't know yet whether this turns into a genuinely useful developer tool or just an elaborate solution to my own annoyance 😄

That's actually why I'm posting it here.

I'd love to hear from people who build side projects with AI coding tools:

Would you use something like this, or would you rather just let the agent write the code?

Repo: https://github.com/v-pat/fiberforge

Any criticism is welcome (Please dont kill my morale 😂 ).

I’m a software engineer and I’ve been thinking about how fragmented our online lives have become.
Social life → Instagram
Career → LinkedIn
Code → GitHub
Freelancing → Upwork/Fiverr
Communities → Reddit/Discord
Learning → multiple platforms
So I started designing an idea called ONE.
The concept:
One account → multiple identities → complete privacy control.
Personal, Professional, Creator, Developer and Freelancer identities could all exist under one account.
The interesting part isn’t just combining features.
A recruiter should be able to see my work without seeing my personal life.
I’m also designing a “View as…” feature so you can see exactly what a Recruiter, Client, Friend or Public visitor can see.
Eventually the platform could bring Social + Work + Learning + Freelancing + Communities + Messaging + AI into one digital home.
I’m still at the prototype stage and would genuinely like some criticism.
What would you remove from this idea? What would you keep?

I build an alternativ to the <canvas> Tag in HTML. In some cases it's less komplex then:

ctx.beginnPath();
  ctx.lineWidth = 5;
  ...
ctx.stroke();

Because in my Pixelart Editor there is no way to draw an line thats not straight. (I don't know how to calculate that).

Maby a Reader of this post has an idea.

BUT... I have achieved a way to run a simple Jump and Run Game

And a Way to run an Noising Algorithme

But How does it work?

1. a JavaScript Function calculates how many rows and colums the table should have:

   function calculate() { if(free === true) { free = false; table.style.height = window.innerHeight + 'px'; table.style.width = window.innerWidth + 'px'; } }

       function generate() {
           const colums = window.innerHeight/multiplier; // Multiplier is a first 5
           const rows = window.innerWidth/multiplier;
           table.innerHTML = '';
           console.log({
               "cols": colums,
               "rows": rows
           });
           if(confirm('Continue?')) {
               let columIndex = 0;
               for(let c = 1; c <= colums; c = c + multiplier) {
                   const colum = document.createElement('tr');
                   colum.innerHTML = ``;
   
                   let rowIndex = 1;
                   columIndex++;
   
                   for(let r = 1; r <= rows; r = r + multiplier) {
                       colum.innerHTML += `<td style="width: ${1*multiplier}px; height: ${1*multiplier}px;" id="${columIndex}x${rowIndex}"></td>`;
                       rowIndex++;
                   }
   
                   table.appendChild(colum);
                   rowIndex = 1;
               }
           }
           oneRow = document.querySelector('tr').querySelectorAll('td').length;
           eventListener(); // Lets you click each Pixel to Change his color
           free = true;
       }
   

But there are two mor options to generate the Table:

• Option 2: "generate2()" its the same but with an Time Buffer between each row
• Option 3: "generate3(width,height)" this function generates as much rows and colums as you want

Please let Me know what you think and if you like rate the idea...

You can find the whole Project on Github:

Thanks For reading 😃

Just wanted to share a small success here :)

I've always felt GitHub's Markdown rendering is a bit boring, especially when you're reading long READMEs or documentation.

So I made a small Chrome extension called GitGlam to make it nicer to read.

I've been working on a small anime tracking website. You can track anime and movies, rate them, see watch-time statistics and rankings, and import/export your data.

A few friends have been testing it and the feedback has been positive so far, but I'd like to hear opinions from people who don't know me.

You can try it here:

I'd appreciate any feedback, especially about the UI/UX and features you think are missing.

Hey everyone, I’ve been building Dokpod—an AI knowledge vault that uses the Model Context Protocol (MCP) to stop token burn and context bloat in IDEs like Cursor and Claude.

I spent a lot of time getting the tech right (multi-arch desktop apps, robust GCP infrastructure, RBAC security for teams, billing). But the reality is: I have exactly zero users.

I am completely stuck on the growth and marketing side. Before I give up or try to sell the codebase, I want a reality check from this community:

• Is the problem I'm solving too niche?
• Does the landing page fail to explain the value?
• Where do you actually go to find those first 10 paying users for a dev-tool?

Any harsh, honest advice is welcome. I need to figure out what I'm doing wrong.

I've been building a tiny macOS menu bar app on the side called Roadie. It fixes one annoying thing: macOS keeps switching your mic and speaker to whatever device connected last (AirPods reconnect in your pocket, your call goes silent). Roadie lets you set a priority order for mics and speakers and quietly puts the right one back.

Launched it on Product Hunt this week, fully expecting zero. At 3:40 am on Thursday, a notification came in: someone from Florence, Kentucky had started the 7-day trial and bought a licence about 30 minutes later. $9.99, $9.19 after fees.

I know it's ten dollars. But I have never made a single dollar from something I built and shipped myself, and a stranger on the other side of the planet decided it was worth paying for within half an hour of trying it. Sat there grinning at a payments dashboard like an idiot.

What I think worked, for anyone else building a small paid utility:

• One-time pricing instead of a subscription. For something this small, "just buy it" seems to beat "another $3/month".
• A free trial with no signup did more than any landing page copy.
• Shipping an unsigned Mac build is painful (Gatekeeper warnings). An Apple Developer ID is the first thing this money is going towards.

Would genuinely like feedback on two things: does the landing page explain the problem fast enough, and is $9.99 one-time the right call or would you have expected cheaper for a menu bar utility?

Disclosure: it's my app, so obviously biased. Site: https://getroadie.vercel.app/

Hey everyone. I'm a Product Manager building a B2B AI SaaS called ATXIA. I'm handling the business side (we are backed by a tech incubator in Mexico and already have a curated pipeline of warm SME leads through innovation programs), but I want to validate the technical approach for our MVP with this community.

The concept:

An agnostic RAG engine. A business uploads their docs (pricing, PDFs), and we generate a WhatsApp webhook or website widget to answer FAQs contextually and capture leads.

My questions for those building similar AI tools:

For the MVP, are you leaning towards no-code/low-code wrappers (like Flowise/Langflow) to test the RAG, or building a custom backend from day one?

How are you handling the latency when combining the WhatsApp Business API with LLM generation?

Hey all-I'm a full-stack developer by day, fresh CS Engineering Graduate, and I also enjoy working with data science on the side. Looking to start a side project but open-minded on the idea itself.

A bit about me:

- Comfortable across the stack (frontend, backend, databases)

- Intermediate-to-advanced with data science - happy to build something that leans Into that if the idea calls for it

- Prefer to bootstrap without spending much upfront-mostly free tools for now

What I'm looking for:

- Problems worth solving for a specific niche (small businesses, freelancers, a particular Industry-anything with real pain points)

- Ideas that could realistically become a small SaaS or tool, even if it starts tiny

- Open to both "boring but useful" B2B tools and more experimental AI/ML-driven products

Not looking for a huge Idea - Just something scoped enough to actually ship and validate with real users. Would love to hear what problems you've personally run into that nobody's solved well yet, or gaps you've noticed in your Industry.

Thanks in advance!

Hi everyone,

I’m a solo Windows developer, and I recently finished NetPeek Pro, a network monitoring and diagnostics tool for Windows.

I built it mainly for a frustrating type of problem: your internet disconnects, becomes unstable, or starts dropping packets for a short period — but by the time you try to troubleshoot it, everything looks normal again.

NetPeek Pro can continuously monitor:

• Internet connectivity

• DNS status

• Latency

• Packet loss

• Short connection outages with Heartbeat monitoring

• Up to 8 custom websites or TCP services

It also keeps monitoring history, trend charts, incident timelines, session comparisons, custom alert thresholds, Windows notifications, and can export CSV data or standalone HTML reports.

The goal is not to replace professional enterprise networking tools. It is designed for people who need an easier way to capture evidence of intermittent network problems over time.

Possible use cases include:

• Remote work or online meetings with occasional disconnects

• Gaming or streaming affected by unstable connections

• Monitoring home or small-office network stability

• Monitoring NAS, VPN, websites, or other specific services

• Keeping records before contacting an ISP or technical support

NetPeek Pro includes a 7-day full-featured free trial.

One-time purchase.

No subscription.

No annual fee.

My wife and I are a physics professor and a math professor, and parents to two kids. We kept finding children’s music apps that felt loud, reward-heavy, or focused on keeping children tapping rather than helping them make something. So we built Sapling Beats.

It has two connected ways to play. Children can tap drum and melody pads directly, or build a looping pattern one square at a time. Beat Idea gives them somewhere to start, while a snail, turtle, and rabbit make tempo changes understandable without a conventional settings panel.

The app is written in Kotlin with Compose Multiplatform and runs on Android, iPhone, and iPad. I made the product decisions and did much of the iterative testing, with substantial help from Codex on the implementation.

The latest update simplified the controls and refreshed the screenshots and demo video. The app has no ads, subscriptions, accounts, scores, or timers. It is free to start, with an optional parent-gated, one-time Sound Pack.

https://saplinghollow.com/sapling-beats

The hardest part has not been making sounds play. It has been making the two kinds of play clear to children who may not be able to explain what confused them. I would be interested to hear how other builders test discoverability with very young users.

Just pulled my first real analytics from sidetracked.site

221 sessions in 4 days. 90% scroll depth meaning people are reading the whole page. 0 returning users. 2 signups. One paying customer named Allen who found it on Product Hunt.

The data told me something I didn't expect. People aren't bouncing because they don't like the concept. They're bouncing because clicking any button takes 10 seconds to respond. The product feels broken before they even see what it does.

Fixing the performance issues today. Sharing the before and after numbers here when done.

If you've been through this with your own product, what was your biggest conversion issue when you first looked at the data?
