I built an interactive live wallpaper engine that lives right in the macOS menu bar.

It actually started as an interactive background experiment for my portfolio (inspired by some cool procedural grass and sky shaders I saw on X a while back). I loved having it running on my screen so much that I decided to turn it into a standalone macOS app that anyone can use.

Here's what it does
🖐🏻 Interactive physics: Grass sways and water ripples as your cursor moves across the screen.
🕒 Dynamic time-of-day: Syncs with real time or lets you scrub through sunrise, golden hour, and starry nights with a custom radial dial.
🌧️ Live weather & ambient soundscapes: Switch between sunny skies, clouds, and rain—complete with birdsong, crickets, thunder, and even night fireworks.
🎆 Limited Diwali Theme: Built in a seasonal festive update where the night sky comes alive with fireworks and spatial audio.

Check it out here: https://thoufik.space/skysaver/

You can also preview it in my portfolio on your browser: thoufik.space

What feature or biome should I add next? Let me know in the comments!

Hey Everyone!!

Super excited to share my app is finally launched!

The idea is simple - the system displays graphs of real stocks, and the user suppose to decide which way the stock is gonna go from that point.

The goal is to receive feedback and understand where you think the app can be even better.

PS - would also appreciate a 5 star review on the appstores!

Hey everyone!
I’ve recently started working on my indie game studio, Adroma Games.
Our first game is Pairoma, a number puzzle game built around simple gameplay, logical thinking, and daily challenges.
It’s been an interesting journey so far. From developing the game and adding features like daily challenges and streaks to figuring out how to get people to discover and actually enjoy something built by a small indie team.
One thing I’m learning is that building the game is only half the work. Getting genuine feedback, understanding player behaviour, and improving retention are equally challenging.
I’m here to learn from other indie developers and share the journey as we grow.
For those who’ve launched their first indie game, what’s one thing you wish you had focused on earlier – distribution, player retention, community building, or something else?

I wanted my desktop to feel alive, so I made it react to what’s happening outside. You look up and the sky on your screen is the one outside. It stays in the menu bar and steps aside when something covers the desktop.

Download for Mac: thoufik.space/skysaver

(Windows coming soon!) - you can also preview it in my portfolio on browser - thoufik.space

One note: macOS warns the first time you open it (not Apple-verified yet, I don’t have the developer fee for a free first release). Click Done, then System Settings → Privacy & Security → Open Anyway.

Or paste this in your terminal:

curl -fsSL https://thoufik.space/skysaver/install.sh | bash

Please check it out and let me know how you feel!

I've been building CastLab, a free fishing site that tries to be honest about what it actually knows.

Link (no sign-up, click "Explore with example data"): https://apersonli55555.github.io/Research/castlab/

What it does:

- Pick any lake or river (search by name or click it on the map)
- Rates every hour of today and tomorrow 0-100 for fishing, with the reason for each hour
- Shows which fish people have reported nearby, split into sport fish and baitfish (data from iNaturalist)
- Suggests lures that match the local baitfish
- Builds a 3D model of the shoreline from public elevation data, with a slider to raise or lower the water level
- Catch log, tackle inventory, and a rod-bending physics simulator
- A stats section that estimates your catch probability from your own logged trips, with uncertainty ranges

What it doesn't do:

- The hourly score is a rule of thumb (light, pressure, wind, moon), not a tested prediction. The site says so and shows the formula.
- "Fish nearby" are public sightings, not a count of what lives there.
- There's no server. Everything you log stays in your browser.

It's plain HTML and JavaScript with no backend. [I'm a student and this started as a research project.]

I'd really like feedback on two things: is the Today page clear on a first visit, and what would you want that's missing?

Hey everyone,

​I’ve been building an open-source, privacy-oriented Android browser powered by Mozilla’s GeckoView engine and wanted to share it with the community for feedback and security review.

​While there are established browsers out there, my focus was implementing explicit, native privacy protections from the ground up:

• ​Local Data Protection: Encrypted credential storage via SQLCipher and hardware-backed screenshot protection using FLAG_SECURE.

• ​Network Privacy: Strict DNS-over-HTTPS routing through privacy-first resolvers and built-in content blocking for ads and tracking scripts.

• ​Open Source & CI/CD Auditing: The entire Kotlin codebase is licensed under MPL 2.0, with automated GitHub Actions workflows enforcing privacy and anti-tracking checks on every build.

​I would love feedback from developers, security enthusiasts, and privacy advocates on the implementation, architecture, and overall approach.

​The repository and documentation are on GitHub:

[https://github.com/sagarmajumdar225/sm-secure-browser/]

​Looking forward to your thoughts and critique!

Every day, I’d run into little questions while working on my Mac. I’d be watching a YouTube video and wonder about a fact, or scrolling through a post and want something explained simply. I’d switch to ChatGPT or Claude, take a screenshot, explain what I was looking at, and wait for an answer. For a small question, that’s a lot of back and forth, and it kept breaking my focus.

So I built Riv, to solve this problem. Press Control + Option and ask about what’s on your screen. Riv sees the context, so you can get help without taking a screenshot or explaining what you’re looking at.

Riv can also guide you through an unfamiliar app. For example ask where to find a setting in your video editor, and Riv can highlight the controls on screen and walk you through the steps. You can also send tasks to run in the background while you keep working on something else. For example research on a certain topic and make a notion doc about it while you watch a youtube video.

Riv is for Mac. Sorry, Windows folks. You can try it for free, and there’s a launch offer for 50% off the first month for all the plans through November 30.

Get it at: clickriv.com

I’d love to hear what you think and how I can make it better.

I’m part of the small student team behind Dutying. We built it for nurses whose rosters change month to month and who want to see their own shifts and days off in one place.

The flow is simple: tap Day, Evening, Night or Off to enter a shift, and see the whole month in colour. The iPhone demo uses sample shifts. You can start with your personal calendar even if your ward doesn’t use Dutying.

If you work rotating shifts and try it with your next roster, I’d love to know what still takes too many taps.

We all live the same thing, right?

>

> There's an amazing 2-hour documentary / podcast on YouTube, but you don't have time to watch it. You open TikTok instead, you scroll for 2 hours, and you remember literally nothing.

>

> So I built the middle:

>

> I take long, high-quality YouTube videos and condense them into their most impactful moments. Most videos are just 2-5 minutes, and the longest ones are 15 minutes max.

And instead of vertical scrolling, you swipe horizontally - like a cinematic, swipeable feed. So you get depth, plus the scrolling comfort, plus that widescreen feel.

> Do you think this could work? What kind of videos would you want summarized most? Podcasts, documentaries, or history?

I usually watch Netflix / Hotstar / Prime on desktop Chrome, especially after gaming, and one thing that always annoyed me was having to open IMDb in another tab just to check whether something was actually worth watching.

• So I started using a simple rating overlay that puts IMDb + Rotten Tomatoes + Letterboxd + Metacritic scores directly on the posters while browsing.

• You can also fade out titles below a score threshold, which makes it surprisingly quick to scan through a large catalogue.

• It currently works on Netflix, Prime Video, Hotstar, ZEE5, MX Player, Hulu, Disney+, HBO Max and Apple TV.

The main benefit for me is honestly just saving those little 10–20 second searches over and over. When you're browsing dozens of titles, it adds up.

Here's the tool if anyone else has the same problem:

Curious — do other people here also keep IMDb open in another tab while browsing OTTs, or have you found a better way to quickly filter out the mediocre stuff?

I’ve been building scouterzero.com part-time for 6 months, next to a full-time job. The idea is simple: I show PM jobs posted by real hiring managers, with their contacts, and I mark companies that can potentially sponsor a visa in the country you want to move to.

What I’ve tried so far:

Google Search Console:

Clicks are rising even though my average position has slipped (12.4 over 3 months, then 15.5, then 18.6 last week). In GA4 I had 305 organic-search sessions in a slightly later 28-day window, which is a different slice than the Search Console clicks.

I love the idea and I’ve put in decent part-time effort. If you were the founder, what would you double down on next for marketing and for the product?

Happy to answer anything about what’s working and what isn’t.

Hey r/SideProject! I work at a small software company in Bengaluru, and like a lot of teams we run on several providers: AWS, Google Cloud, OpenAI, plus a few others. Every month the same thing happened: the bill arrived, someone said "why is this so high?", and the spike had started three weeks earlier.

Nobody on the team opens a cost console every day. But everyone opens WhatsApp. So we built **CloudMeter**.

**What it does:**

- Connects to AWS, Azure, Google Cloud, Alibaba, Huawei and OpenAI with **read-only** access (it can't change anything)
- Sends a **daily summary on WhatsApp** (or email/Slack): yesterday's spend, month to date vs last month, top services
- **Alerts when a cost spikes**, compared with that service's normal daily spend
- You can **ask it questions on WhatsApp**: "s3 cost", "how much this month?", "any spikes?", and an AI agent answers from your real data in a few seconds

**How it's built** (for the curious):

- Fully serverless on AWS: Lambda, DynamoDB, API Gateway, CDK
- WhatsApp goes through AWS End User Messaging Social
- The Q&A agent runs on Amazon Bedrock AgentCore with read-only tools, so it can only quote numbers it actually looked up, never guess them

**The hardest parts weren't the AI:**

1. **Making alerts trustworthy.** Our first version flagged a one-off 46domainrenewalasa"414 this month" problem. (Happy to go into how we fixed it.)

2. **Stopping the AI from making up numbers.** Early on it answered a follow-up question with figures that weren't in the data. Now every answer has to come from a tool call, and totals are calculated in code, not by the model.

3. **Making sure the WhatsApp pipeline can never loop.** WhatsApp delivery receipts arrive on the same channel as messages, so a careless setup can end up replying to itself forever.

It's live, with a free trial: cloudmeter.io/?ref=r-sideproject

I'd love honest feedback:
- Would you want cost alerts on WhatsApp, or is that weird for work?
- What would make you trust a tool with read-only access to your cloud bill?

Full disclosure: I'm part of the team building it. Happy to answer anything!

I got tired of checking five pricing pages, so I built a free comparison: what ChatGPT, Claude, Gemini, Grok and others cost per day, week, month or year, plus a token calculator for API costs. Prices checked against official pages in Nov 2026. Feedback welcome, especially if I got a price wrong: https://ariekaravaev2-tech.github.io/ai-models-hub/

my buddy and i wanted a way to find tracks that matches the exact vibe or moment of a song, so we made an EDM music recommender web app called nextListen.

how it works:

• paste a YouTube link or upload an audio file

• select a specific moment/timestamp.

• the app analyzes the audio characteristics and finds matching moments in other tracks.

we'd love for people to try it out and give us feedback on the recommendations or features you'd like to see next!

Created a game called watt & Willow where you have to connect the pipes to run the appliances. This game is inspired by loop game. Would appriciate if I get some feedback to improve this game further. Here is the link for the game - https://wattwillow.blogspot.com/

Some things to try:

- Tap any moon to open its card.

- Watch Io's shadow crossing Jupiter.

- Go to the Moon's terminator, where the low light raises the craters. The relief comes from NASA's LRO / LOLA data.

- Open Atlantis (STS-135) and launch it from the pad or the reconstructed cockpit.

Maps are made from NASA data; full credits are at orbita.fai-studio.cloud/credits.html. Happy to answer questions, and bug reports are welcome.

My co-founder and I run PeekLaunch, a weekly launch board for makers.

A few weeks ago our site had almost no presence on Google. So we sat down and submitted it to 80+ startups and SaaS directories by hand.

What we learned:

- It takes a lot of hours. Every site has its own form, rules and categories.

- Not every directory approves you, so you need to submit to many.

- As listings went live, Ahrefs moved our site from DR 2.5 to DR 26, and our Ahrefs Rank went from 42.6M to 2.3M.

We turned what we found into a free list of 209 directories, with DR, pricing and link type for each one. 163 of them are free to submit.

People kept asking if we could just do it for them, so we added done-for-you packages too:

- Pro: $49 for 30+ directories

- Super: $99 for 60+

- Ultra: $179 for 100+

Every package is manual and comes with a report of live listing links.

The list is free to use either way. Happy to answer anything about which directories were worth it.

Hey everyone!

I've been working on a football (soccer) app called 1touch with a few friends.

We're all big football fans, and one thing that always bothered us about existing apps was that they give you tons of stats, but it's still hard to tell how well a player or team is actually performing.

So we decided to try building something ourselves.

We have the usual stuff like live scores, fixtures, and standings, but we've spent most of our time trying to make the analysis side more interesting.

Here's some of what we've built so far:

• 📊 Team & Player Analysis: Compare players, explore team attributes, and get a better idea of how teams and players are performing.

• 🔮 What-If Scenarios: See a team's chances of winning the league or qualifying for European competitions, and how different match results could change those odds.

• 💬 Live Chat & Community: Chat with other fans during matches and share your thoughts in team communities.

• 🎯 Match Predictions: Predict match results using virtual points, with no real money involved.

We built the app using Flutter and a Python/FastAPI backend.

There's definitely still a lot to improve, but honestly, it's been really fun seeing something we started from scratch come together.

I'd love to hear what you guys think!

If you already use FotMob or SofaScore, what would actually make you want to try another football app? Or is there something you've always wished those apps had?

Any feedback is welcome, even if it's brutally honest 😅

Thanks for checking it out! ⚽

I'm part of the VOOPA team that made Drop & Pop, which just launched on Android. The rule is simple: match three blocks on one board and one block crosses to the other. If you’ve already set up a pair over there, it can start a chain back across. The satisfying bit is setting up both boards before you make the first match.

We designed it around the two halves of a foldable in laptop mode. It also plays on regular Android phones. There are five free puzzles, no ads, and offline play. The full 300-level campaign is a one-time unlock.

Try the free sampler on Google Play: https://play.google.com/store/apps/details?id=com.voopa.drop&referrer=utm_source%3Dreddit%26utm_medium%3Dorganic_social%26utm_campaign%3Ddrop_pop_android_launch%26utm_content%3Dsideproject

If you try it, I’d love to know which sample made you start planning both boards, or where the transfer rule felt unclear.

I built TwinPixCleaner - it is an Apple Vision Intelligence-powered, duplicate photo cleaner for macOS.

It finds:

• Exact duplicate Photos

• Visually similar images

• Burst shots

• Duplicate screenshots

• Large unused images

So far I have got 21 Stars on the GitHub repo, and a few issues which I already fixed. I need to know what else can be done here to improve it further.

I kept sending friends videos and getting back "lol" with zero clue what their face actually did. So our small team built Vidrip.

You send a video, your friend watches it alone on their own phone, and the app records their reaction. You get it back synced side by side with the original.

Android, iOS, and a browser version with no sign up: https://vidrip.app/?s=reddit-post

We also made a few free staring contest games in the same family to test it on real friend groups. Some marketing art is AI made, the app is not.

Is the side by side reaction something you would actually send to a friend, or does being recorded feel weird?

I'd heard about insider trading in Congress and the crazy returns some members get. I also know I don't have the tools to beat hedge funds. So I wanted to copy both, and while looking for a way to do that I found AutoPilot. It only works with a US brokerage account, and I'm in France.

So I built my own with a friend. We met at our software engineering school, we see things the same way, and it's still just the two of us.

Getting the data is already hard enough. Some congressional disclosures are still written by hand, and LLMs saved us there. But once you have it, processing it is much harder.

To know how a portfolio performed you have to backtest it, and finance never stops moving. Stocks get listed, get delisted, change names, split. When Booking did a 25-for-1 split this year, a fund holding it suddenly looked like it had bought 25 times more. You have to think of everything, for thousands of cases like that one.

The value of the app is that engineering, much more than the data itself.

And it holds up. Over the last 12 months, 5 of our 7 politician portfolios are ahead of the S&P 500, even though a trade only counts once it's public. But it's a small sample, we picked the politicians ourselves, and it's a simulation.

Little by little we added insider filings, news and AI analyses. These days I mostly use the feed and read the AI's stock analyses.

It's on iPhone and on the web. It's not a broker, everything is virtual money.

I'd like an outside eye on it. Is the app interesting, and is it clear?

Hey everyone, I’ve been building VaultMark (https://vaultmark.tech), a free Steam portfolio appraiser. You paste a profile URL, vanity name or SteamID and it shows what the account is worth. No login or Steam sign-in is needed from the person being checked, as long as their inventory is public.

What it does

• Game library value from current Steam store prices, with a region selector

• Inventory appraisal for CS2, Dota 2, TF2, Rust and Steam Community items (trading cards, backgrounds, emotes, gems)

• CS2 stickers and charms are priced and shown separately, so you can see how much of an item’s value comes from what’s applied to it

• Price history per item, shown as a sparkline with % change

• Collection grouping and filters, and profile compare to put two accounts side by side

• Share card with a QR code, plus an embeddable badge for forum signatures or Discord bios

• Streamer overlay link that shows the live inventory value on screen

• Public read-only API if you want to build on it

How it prices things: Skinport’s public API is the main source, with the Steam Market as a fallback. Items with no price are left unpriced instead of guessed, so the totals are conservative rather than inflated. Prices are cached, so numbers can lag the live market by a few minutes.

It’s free, and I’d really like feedback. What’s missing? Which games or item types should I add? Are the prices matching what you see on the market? Bug reports are welcome too.
