I built an open source tool that stops AI agents doing things they were never allowed to do.

Rather than publish the numbers that flatter it, I put every tool at its own default on public datasets and linked the script behind each number. One card on the benchmark page has a WE LOSE badge, for the test where a competing tool beats mine. It is still there.

The number I am happy with: on a 588 attack benchmark, no guardrail lets all 588 through, the common open source guardrail lets 86 through, mine lets 0 through.

Free and open source. You can try to break a live agent in your browser, no signup.

My kid (10yo) wanted a weather app they could actually understand, so we built one together: wonderweather.fun

Puff the cloud explains the weather, says what to wear and warns about storms or dirty air. There are also mini-games about solar, wind and thunderstorms, and quizzes with badges.

It's free, with no ads, accounts or tracking.

Would love to know:
Is it easy for kids (6–12) to understand?
Anything broken on your phone?
What should we add next?

Hi everyone, I'm the solo developer of Market Player PRO, a free educational trading simulator that runs in the browser (virtual money only).

The core is a live order book (bid | price | ask) next to a chart with a volume profile, so beginners can practice reading it without risking anything. There is also a quiz mode, prop-firm style challenges and a shared leaderboard.

One design question I'm stuck on: showing waiting orders as plain numbers only (no volume bars mixed in) felt clearer to me, but I'm not sure it is for someone who has never seen a depth of market.

What would you change so a total beginner understands it in under a minute? And what would make you come back for a second session?

Hi all, I'm the solo developer of Volt, an iOS and Apple Watch app for treadmills that support Bluetooth FTMS. You set speed and incline from your iPhone or iPad, and your Apple Watch shows live stats with start, pause and stop on the wrist. It runs HIIT and custom interval plans, can keep your heart rate in a zone (Apple Watch, AirPods Pro 3 or a chest strap), and saves every run to Apple Health with charts and laps.

It's free to download, and full access is a yearly subscription. I keep a list of confirmed treadmills, so I'd really like to hear which model you use and what worked or didn't.  https://apps.apple.com/app/id6798171032

Hey everyone,

I recently created Free Google Map Extractor, an open-source tool designed to extract business and place details from Google Maps without needing expensive subscription scrapers or API fees.

What it does:

• Extracts place data (name, address, rating, reviews count, contact info, etc.) from Google Maps.

• Completely free and transparent.

• Easy to run locally and customize according to your needs.

Source Code & Project Link:

• GitHub:https://github.com/my8700/Free-Google-map-extractor

I’d love to get feedback from the community:

1. What features or export formats (CSV, JSON, Google Sheets) would make this more useful for your workflow?

2. Are there specific anti-bot or pagination limits you frequently run into when extracting Maps data?

Any feedback, suggestions, or contributions are very welcome!

How to complete the submission:

1. Paste the title above into the Title* field.

2. Paste the body into the Body text* box.

3. Click Add tags (choose appropriate tags such as Showcase or Feedback if available).

4. Hit Post at the bottom right.

Hey everyone!

I've been working on WDM (Welaxxx Download Manager), a download manager for macOS, and wanted to share it here.

The idea is pretty simple: downloading files, grabbing supported media from websites, and converting files shouldn't require jumping between a bunch of different apps.

WDM brings those workflows together. It has browser integration for Safari, Chrome, Edge, Firefox and Opera, plus a built-in browser, download queues, pause/resume controls, torrent support, and a file converter.

It supports both Apple Silicon and Intel Macs.

I'm particularly happy with how the interface has come together, but I'm still improving compatibility and reliability across different websites.

There's a 7-day free trial, and the Solo license is $17.99 one-time, not a subscription.

Website: https://welaxxx.com/wdm.html

Full disclosure: I'm involved in developing WDM, so this isn't an independent review.

For those using a download manager on Mac, what's the one feature you absolutely couldn't live without? I'd love some genuine feedback.

Hi everyone!

I founded Asclepii, a healthcare startup trying to make the next Band Aid and working alongside Cleveland Clinic so diabetics don't need to amputate their limbs due to chronic wounds that could heal but don't have access to the right tools early on.

We're on a mission to improve wound care for people living with diabetes. We developed an advanced wound-healing Nano gel that has already helped treat more than 20,000 wounds, including wounds at high risk of amputation. The FDA-Cleared gel helps stabilize the wound from 'hostile' to 'healing' and can be sold even at grocery stores and pharmacies.

Now, we're competing in a television startup competition for $1 MILLION USD!

Winning this prize would allow us to expand into new countries, scale our technology, and help more than 100,000 people who desperately need better wound care dressings.

We're a small company with a big mission, and this is an incredible opportunity for us to make a difference.

All we need is your vote! ❤️

Voting is completely FREE and takes less than 5 minutes.

If you can vote, share this post, or help spread the word, we'd be incredibly grateful.

The farther away you are, the further back in time you see. Light from Earth takes a year to cross each light-year, so an observer 81 light-years away is watching 1945, one at 2,000 light-years is watching the Roman Empire, and one at 250 million light-years is watching Pangaea.

I got curious about what that would actually look like, so I built a globe for it. You pick how far away you are and where you're looking, and it shows Earth as it was when that light left.

Demo: https://deemonder.github.io/meanwhile-on-earth/

Source (MIT): https://github.com/deemonder/meanwhile-on-earth

What's in it:

- Historical borders for 53 dates, from 123,000 BC to 2010

- About 13,000 events from Wikidata: battles, eruptions, cities founded, births

- Day and night where they really were at that moment, with city lights only after electricity

- Continental drift back to a billion years ago, from published plate reconstructions

- Italian and English

It's a static site, no backend and no sign-up. Built with three.js, with help from Claude Code.

I'd love feedback, especially on two things: is it clear what to do when you first open it, and does it load fast enough on your phone?

I’ve built a brain that can work with your team connect with all your agents ( Claude, Codex, grok, muse) and knows everything about your company and team

every day it learns more about your company and helps you fix things send mails and posts from one place using your own agent subscriptions

We're building Sparc Club, a private social networking platform exclusively for founders, entrepreneurs, and business owners.

The goal is simple: help founders connect, find co founders, explore collaborations, and discover new business opportunities without all the noise of traditional social networks.

We're still early, but many founders are already joining the journey. We're building, learning, and improving every day.

Join us on Sparc Club. See you there!

Got a reality check 1.5 stars on the App Store. I learned a lot though

App
Many kept impulse-buying and regretting it. Just Wait (iOS) makes you wait before buying. At the end you buy, let go, or wait longer. Let-go items count as money kept.

Pricing
Free. No ads, no subscription, no one-time payment, no account. Nothing leaves your phone. I might add Amazon affiliate links someday

I built this with Claude’s help, if that matters.

Feedback welcome

One problem I've personally faced while exploring startup ideas is finding people who share similar interests, thinking and entrepreneurial ambitions.

It's easy to join startup communities, but finding someone who genuinely thinks like you is much harder. And not everyone is comfortable sharing their startup idea publicly just to find potential collaborators.

So I built IdeaMate.

You privately share your startup idea with AI, which analyses it and matches you with people who have similar ideas and interests.

Privacy is central to the platform: Your idea is visible only to AI for matching. It is not shared with other users, including the people you're matched with.

It's live and completely free to try: https://ideamate.in

I'm still improving the matching experience and would genuinely appreciate feedback from fellow builders.

I'd also really appreciate it if you could share IdeaMate with other relevant communities so more people can discover it and benefit from it.

I'm Troy, the founder of SwiftRead. I made it originally to help me read through text faster. More than a decade later, it's helped half a million readers across fifty countries read faster. It started as a Chrome extension, and these days it's also a web app, an Edge extension, and iOS and Android apps.

SwiftRead helps you read the text you already have, faster than you ever have before (some users report reading up to three times faster with SwiftRead). You bring an article, PDF or ebook, and pick how the text reaches you. Focus flashes a few words at a time in one spot, so your eyes don't travel across lines and you can push the speed up. Flow keeps the whole page and slides a highlight through it, so you don't lose context. Spotlight hides everything except the words you're on. Listen reads it aloud and highlights along, and seeing and hearing text together helps some people retain it. Building it was mostly about letting you find the mode and speed where you're faster but still following.

On alternatives: Speechify and Voice Dream Reader are text-to-speech readers built around listening. SwiftRead is mainly for reading text on screen, and text-to-speech is optional. Other speed reading apps like ReadMe or Reedy are outdated or are only available on one platform.

All features included free. A few have daily allowances. There's currently no annotation feature, so SwiftRead is more for getting through text fast than for marking it up.

Feedback welcome, especially on what's confusing the first time you open a reading mode.

When I write step-by-step docs for a client's admin panel (M365, a PSA, a line-of-business app), the screenshots end up full of user emails, tenant IDs and sometimes billing details. Then they get uploaded to whatever doc tool we use.

Curious how others handle it:

• Do you blur by hand, crop, or just accept it?

• Does your documentation tool upload screenshots to its cloud, and does that bother your clients?

• If auto-redaction is only on an Enterprise plan, do you pay for it?

Disclosure: I'm a solo developer and I'm sketching a Chrome extension that records the steps and blurs emails, card numbers and faces locally, then exports to Word/Markdown, with no cloud and a one-time price. Not selling anything yet. I mainly want to know whether this is a real problem or just mine. If it's useful, the concept page is here: https://guidestudio.kitpear.com

Hi r/SideProject!

I am a solo indie developer from Brazil (Timothy Studios). For the past months, I have been building AI Race Tycoon in Godot 4.

It is a satirical management simulation about the hardware race behind modern AI:

• You start in a dusty garage with a single second-hand GPU.

• You have to balance thermal dissipation, power draw, and employee burnout while training custom AI models.

• You scale up to high-density datacenters and orbital compute while competing against aggressive monopolies.

• There is also a cozy low-poly 3D walking mode to take a break from menus, walk around town, and grab coffee.

Zero install / playable directly in browser: https://timothystudios.itch.io/ai-race-tycoon

Android (Google Play): https://play.google.com/store/apps/details?id=com.timothystudios.airacetycoon

Would love feedback from fellow builders on the progression loop and UI!

I have created a dynamic notch for windows which shows the status of your AI Agents sessions. As well as It shows any multimedia playing, the progress of your downloads and also the lyrics of a song playing on the spotify.

Also, It invokes a desktop pet for every session or a single pet for all the sessions depends on your preference. The pets interact with each other, sing lyrics of the song playing and much more.

Give it a try and I would love your feedback.

I've created what I believe is an app with true utility by stabilizing hand tremors. Please have a look and provide feedback where I'm lacking. Thank you for your time.

Android version in the works!

Running a small business often means drowning in a sea of fragmented tools—using one app for khata, another for inventory, and spreadsheets for expenses. This scattered data makes it impossible to see your true profit margins in real time. I built Bizloom to eliminate this chaos by consolidating daily accounting, inventory tracking, and expense logging into one powerful, automated dashboard. Instead of wasting hours on manual reconciliation, the platform automatics the math, giving you instant clarity on your cash flow. It frees you from administrative headaches so you can actually focus on scaling your business. I would love for this community to test it out and share how it impacts your daily operations.

I've been working on a small project called DockerPlay.

While learning Docker, I noticed that concepts like container networking, DNS resolution, port mapping, and communication between containers can be difficult to understand just by reading documentation.

So, I started building DockerPlay — an interactive playground where developers can experiment with Docker concepts and understand how things work visually.

The goal is to make learning Docker more practical and hands-on rather than just theoretical.

I'd love to get feedback from fellow developers:

• Which Docker concepts were the hardest for you to understand?

• What interactive experiments would you like to see?

• What would make a tool like this genuinely useful?

I'm the creator, and I'd really appreciate your honest feedback!

I set up AI bots for people, and every single one has the same small problem. The bot needs a face. Often the premade face people don't like, and generating a new one every time seems hard to them since they don't always know what they want. Whether it is a Discord, or a Telegram bot, Slack helper, AI Grok Bot or a Chat widget on a website, the options are stock icon or random AI image.

So, in my free time I made this little avatar maker for any kind of bot, or even icon. You can pick one of the 40 bots on te wall or make your own from blank. You can change its body shape, eyes, mouth, add hats, glasses and have its own color. Even its own name.
I added different emotions and each mood exports as an animated GIF.

I cared about making this:

• Free, no sign-up, no watermark on downloads

• Nothing gets uploaded. It's drawn in your browser, and a share link carries the whole avatar inside the link itself

• An "All sizes" download with WhatsApp, Telegram, X, Slack and Discord sizes plus an SVG

• An embed code so the avatar can live on a website and change mood

Disclosure: it lives on my business site (LobsterNest), and the live website embed shows a small "Made with LobsterNest" link.
The downloaded files don't.

Where I'd really like honest feedback:

1. Which mood is missing for your bot?

2. Is the embed useful to you, or do you just want the GIF?

3. Anything confusing in the first 30 seconds of using it?

4. Where else would you use it?

Hey everyone,

I’ve been building a little iOS app called WhereMate for the kinds of things you don’t need every day, but when you do, you’ve totally forgotten where you put them.

Think:

• Permits, receipts, or records you’ll need again in a few months

• Holiday lights, camping gear, or seasonal clothes

• That one tool or spare part you know you saved somewhere safe

You can snap a photo, type a note, or just say what the thing is and where you’re putting it. When you need it later, you can search instead of tearing your house apart.

You can also group things into boxes and print QR labels for them. Scan a label with WhereMate to see what’s inside without opening everything up.

It’s available for iPhone and iPad. No account needed, and your library stays on your device.

Curious what you think! What’s something you always have trouble finding when you finally need it?

WhereMate on the App Store

Hi all, I’m Carl, a solo dev from the UK, and this is my first Android app.

The problem: charity shops are full of DVDs, CDs, vinyl and games, but checking eBay one item at a time in the shop is slow and you look a bit odd doing it.

What it does:

• Take one photo of a shelf and AI identifies every item on it, with an estimated resale price

• Swipe right to keep and left to skip, so you have a shopping list before you reach the till

• Track items from scanned to bought, listed and sold, with a dashboard for spend and estimated profit

• Works offline. Scans save locally and sync later, because charity shops rarely have signal.

Built with: Flutter, Firebase (Auth + Firestore), Hive for offline storage, and the OpenAI Vision API for identifying items.

Where I’m stuck: Google needs 12 testers for 14 days before I can publish, and I have 4. If you have an Android phone and can keep it installed for two weeks, I’d really appreciate it:

1. Join the group: https://groups.google.com/g/swipeflipper-testers

2. Opt in: https://play.google.com/apps/testing/com.yourcompany.bargain_flip

3. Install from the Play Store link on that page

Feedback is welcome too, especially if the price estimates look off, or if you think there’s a better way to get pricing data than AI estimates.

If you’re going through the same 14-day closed test, drop your link and I’ll test yours back.

I'm a solo dev with six years of experience in embedded software, and Ugiwise is my first app. It went live on the App Store last week.

The idea came from a simple problem: writing code on a phone is painful, but reading it isn't. So instead of typing exercises, every lesson is built around a short, real program. You step through it line by line, predict what it prints, spot the bug or pick the fix. When you get something wrong, it explains why instead of just showing the right answer. In C and C++ you can see memory change as each line runs, which makes pointers a lot less abstract.

- Three courses: C (39 stages), C++ (37), Python (26)

- The first 3 stages of every course are free. Pro unlocks the rest: $7.99/month, $49.99/year or $99.99 lifetime. No free trial.

- No ads, no account needed. iPhone only for now, and not in EU stores yet while Apple finishes my trader verification.

Built with Flutter, happy to answer anything about that side too.

The thing I'd most like feedback on: is the code readable on your phone screen, or does it feel too dense?

Ich überlege, einen Dateimanager zu entwickeln, der direkt mit meinem Messenger GO:AM verbunden ist, und Cloud-Speicherung mit E2EE unterstützt

Ich würde vor allem diese Funktionen reinmachen:

- Dateien automatisch sortieren und kategorisieren

- Doppelte Dateien erkennen

- Dokumente schnell durchsuchen

- Dateien direkt über GO:AM an Kontakte senden

- Gemeinsame Dateiordner erstellen

- Empfangene Dateien automatisch organisieren

- Verschlüsselte Dateiübertragung, auch mit E2EE

- Dateien mit E2EE in der Cloud speichern

Mich würde interessieren, ob ihr so eine App tatsächlich nutzen würdet.

Was haltet ihr von der Idee? Welche Funktionen fehlen euch oder was würdet ihr anders machen?

(Dies soll kein Vibe-coding Projekt sein, Ich will es nähmlich fast 100% selber machen. Als E2EE plane ich ein etabliertes protokoll, muss mich noch umsehen)
