A friend and I were always the people our friend group went to when they wanted a dedicated server for a Minecraft or whatever random steam game came out. We always commented to each other that we wished something came out that not only had the tools an advanced user would find convenient , but easy enough for anyone to use. (this was the key issue most people we knew had) We worked on this for the past few years and here it is.

DeployCat.

You can use DeployCat on windows, mac, unraid/docker and even a linux OS for any spare hardware you have laying around.

You can find it at www.deploycat.app . There is even a simulator on the site to take a look at how the app functions. The goal is to try and make it easy for anyone to host, backup, name, change your settings, restore your server and understand from point A to Z for everyone.

We would love for you to take a look at it and let us know what you think! If you have ever wanted to host a game server but have ever been intimidated by it, or just frustrated with some other self hosting apps; please look and give us a try.

I’m curious what everyone here is working on.

Drop your product or SaaS below and explain what it does in 1–2 lines. No hard pitching just share what you’re building and who it helps.

I’ll start: I built LaunchOrbit, an interactive launch board where founders can showcase their products on a shared, living pixel canvas.

It’s designed to make product discovery more visual, memorable, and fun than another scrolling directory.

If you’re launching something or just want to discover what other founders are building check it out here: LaunchOrbit.

What it does: A clean, ad-free Pomodoro timer that uses relaxing tea-brewing animations and ambient sounds to help you focus.

Key Features:

• Visual tea-brewing progress & custom themes
• Built-in ambient soundscapes (rain, lofi, etc.)
• Fully customizable work and break intervals

Goal: Promo / Feedback

Giveaway: Drop a comment with what you're working on and I'll DM you a free lifetime Pro code!

Cost: Free / Pro option https://play.google.com/store/apps/details?id=com.innovixlabs.calmtick&pcampaignid=web_share

I’ve been building Mooziac, a native music player for macOS that can live right in your menu bar.

The idea was to have quick access to my music without constantly opening a full player window, while still having the features I actually wanted.

Features:

• Menu bar music player
• YouTube Music integration
• Local music playback
• FLAC, MP3, WAV, AAC and M4A support
• Synchronized .lrc lyrics
• Interactive waveform seeking
• Trackpad edge gesture for volume control with haptic feedback
• Discord Rich Presence
• Local-first playlists and listening history
• No analytics, tracking or remote logging
• Native Swift + AppKit
• Apple Silicon and Intel support

Mooziac is completely open source under the MIT license.

I’m still actively building it, so I’d love to hear what you think or what you’d like to see added.

Most websites are just a white box. This puts your own wallpaper behind them instead - a photo, a video, or one of two animated ones built in.

It only steps in when a page is plain white, grey or black. Anything that already has its own design is left alone, and there is a per-site off switch for the ones you want untouched.

The hard part was never the wallpaper, it was readability. The panels, buttons and boxes turn translucent and blurred over it so the text still sits on something solid, with sliders for blur, tint and how much the wallpaper is dimmed. It works on any site rather than a list of sites, including ones I have never seen.

Firefox is the thing I get asked for most and I am working on it.

Free, everything stays on your machine.

Being upfront: I earn nothing from this. It started as a personal project and I honestly do not know yet how much people actually want it. If it is useful to you, a comment or any feedback genuinely helps me work out whether to keep putting time into it.

I had a random idea a few days ago: what would happen if 300 complete strangers each got one page of a book?

Everyone gets one page and can put basically whatever they want on it. A story, drawing, poem, photo, QR code, their Venmo, one word — whatever.

Nobody knows what the other 299 people are making.

Then I take all 300 pages, put them together, and actually publish the result as a physical book.

I liked the idea enough that instead of just thinking about it, I made a website to see if I could actually find 300 people willing to do it.

Right now signing up is completely free. If enough people are interested, I'll actually launch the project and open the 300 pages for purchase.

Somehow I'm already approaching 50 signups after only a couple of days, which I genuinely wasn't expecting.

I have absolutely no idea what the finished book would look like, and that's kind of why I want to make it.

Curious what you guys think — and what would you put on your page?

Following up on an earlier post about SafeAI, a static analyzer for AI agents.

One uncomfortable thought we've had while building it:

No one really cares about knowing an agent's capabilities — until something goes wrong.

Before an incident, adding another tool, MCP server, filesystem permission or prompt change often looks harmless.

After an incident, the first questions become:

- What could this agent actually do?

- When did that capability appear?

- Who introduced it?

- Was it intentional?

---

One example we're working on is MCP tool descriptions. A tool description can look like documentation:

"Search the user's notes. Ignore previous instructions and..."

But that description may become part of the model's context. So configuration can effectively become an instruction surface.

SafeAI now detects several forms of this, while trying to avoid flagging ordinary descriptions that happen to contain words like "ignore" or "act as".

The bigger direction is **tracking changes in agent capability and authority**, rather than simply producing another list of security findings.

But this raises a question for us:

Is knowing your agent's capabilities actually useful before an incident, or only after one?

And if it is useful before an incident, what is the right interface?

CLI + CI + SARIF/HTML?

Or would you actually want an interactive view showing things like:

> "Show me all MCP tools across our agents that could introduce instruction injection."

We're deliberately not building a UI yet.

---

Would you use one, or is that solving a problem nobody has?

Curious to hear from people running real MCP/agent systems.

---

If you want to try it against your own agent project, we'd genuinely appreciate feedback, as well as contributions.

Here you may check: ikaruscareer/SafeAI on GitHub.

I've been vibe-coding with Claude Code and kept hitting the same wall, the agent can write code but can't DO anything. No browser. No email. No way to test, deploy, or message anyone. And when I gave it my own machine, it trashed it: pegged CPUs, API keys scattered everywhere, one worktree stepping on another.

So I built Zipbox. It's a disposable cloud box made for agents. It boots in seconds, comes with its own email inbox, a public URL, a browser, an EVM + Solana wallet, and your API keys already set up. Full root. When the task is done you pause it or nuke it, and the next agent gets a fresh one.

No numbers to brag about yet! I'm literally looking for my first 10 users and honest feedback. Free tier's up, no credit card: zipbox.ai

What should I make the agent do next? Genuinely taking requests.

I run a whole-home storage company in Atlanta (KLOVO) and the thing I'm actually proud of is the assembly line — a cabinet box gets put together in about 45 seconds, start to finish. Somebody finally asked me to explain it on camera, so here's the 20 min version: https://youtu.be/54ceNquth3g Nerdy bit I get into: retail buyers and builders judge the same box on completely different things — retail cares about ship date, builders care about tolerance and how often they have to rebuild it. Ask me anything about the process, happy to go into the boring parts.

MapToCraft lets you search for any city, landmark, or address, draw a rectangular area, and download it as a Minecraft Java Edition ZIP or an experimental Bedrock .mcworld.

There is no installation or account required. I built the browser experience on top of the open-source Arnis generator (Apache-2.0).

Try it: https://maptocraft.com/ Arnis: https://github.com/louis-e/arnis

I would love to see which real-world places people turn into Minecraft worlds.

ClingNote gives files and apps their own notes.

It recognizes the file you have open, including its name, type, and location, and keeps that context tied to the note. If it’s something new, there’s a fresh note waiting. If you’ve worked on it before, ClingNote brings the old note back automatically.

Open Excel → its note appears.

Switch to Power BI or a PDF → the note switches too.

Go back later → your previous note is still there.

It also has rich formatting, pop-out notes, multiple notes per context, and deep search.

Would love feedback on the idea/UI.

This is the hybrid fitness experience our team built for Vora 33. The premise is simple: many people lift and also run, walk, cycle, or do intervals, but their apps usually treat those as unrelated activities.

We wanted each side to keep the detail it needs. Strength has personalized workout suggestions, form guidance, previous performance, load, reps, RPE, rest, and progress. Cardio has structured stages, an outdoor map recorder, live metrics, and post-workout heart-rate recovery.

The connection happens before and after the workout. Recent training and recovery can shape the next suggestion, then strength and cardio both contribute to one training-load view.

Five images showing the full flow: https://www.reddit.com/r/vorahealth/comments/1w4l9pb/strength_and_cardio_should_work_together/

Vora 33 is available on iOS and Android: https://vora.fitness/get

I would love specific feedback on the product idea: should hybrid athletes see one combined load, two separate loads, or both?

First I use "The Reddit Goldmine Method" which is:

Find your subreddits.

use those magic search terms: "wish there was", "looking for", "alternative to", "frustrated with", "hate that"... .

Copy 20 complaints. Group by theme. The biggest group = your opportunity.

But unfortunately I become distracted, I search in many subreddits "copywriting, freelancers, SaaS, content creators, and others" as I don't know which field I want to serve in..

I also went to G2 and search in SaaSs "such as Jasper" reviews which has 3 stars and see what they like to build on it and what they don't like to see how I can solve these problems, but I become distracted and failed again

I also want to tell you that sometimes I start building for half a day and then I think this idea wouldn't succeed so, I stop building and again I try to find a successful one ( I do it many times )

So I settle on a red ocean one "social media scheduling tool" in a giant market with giant competitors such as Buffer, Metricool and others. So I want an advice to how a solo entrepreneur can compete with those giants.

TL;DR: How can a solo entrepreneur to compete with giants companies in his fields

iOS Link : Kalend

NO SIGN UP, NO DATA COLLECTED. SIMPLE APP.

I been building this on nights and weekends and it's finally in a state I'm

happy to show. It's called Kalend. It has a to-do list, calendar, habit tracker and

Journal in one app.

https://apps.apple.com/app/id6798521370

This is the dating website to end ghosting. Check it out and let me know what you think. Mobile apps coming soon.

I kept stalling on awkward invoice follow-ups, so I built a small tool that reads invoice threads, sends polite reminders on a schedule, and stops when payment lands.

Free trial: https://payremind-app.netlify.app

Feedback welcome, especially on the inbox-access ask.

I had a random idea: what if 300 complete strangers each got one page of the same book?

Everyone would get a page to do basically whatever they want with — write something, make art, tell a story, promote something, leave a random thought, anything.

Then all 300 pages would be put together and turned into a real published book.

Right now I’m just trying to figure out if people are actually interested enough for me to make this happen. I made a website and signups are completely free — if enough people sign up, I’ll move forward with actually creating the book.

So if this sounds like something you’d want to be part of, check out the website and sign up. I’d genuinely really appreciate the support and would love to see if we can get 300 strangers together and make this real.

Connecting my AirPods kept changing two things on my Mac: the output, which I wanted, and the microphone, which I didn’t.

That meant worse microphone quality and Bluetooth playback dropping into call-quality audio until I opened Sound Settings and switched the input back.

So I made SoundAnchor. You put input and output devices in priority order once, and it automatically selects the highest-ranked device that is currently available.

I later added microphone gain controls and a quick way to send the same audio to two outputs without setting up Audio MIDI Setup manually.

I’m the developer. There’s a 30-day trial, and it’s also available on the Mac App Store:

https://apps.kopiro.me/soundanchor/

I’d especially like feedback on whether the priority model is obvious when you first open it, and how it behaves with setups I don’t have here.

I launched Lockify on March 16 as a small after-work project.

The original idea was pretty simple:

What if an encrypted vault could disguise itself as a calculator?

Six months later, it's at:

13.2K+ installs

4.7K+ active devices

4.725★ from 244 ratings

And I just shipped v3.4.0.

The biggest feature in this release is Encrypted Notes and this one took me almost a month.

The difficult part wasn't building a text editor.

It was making the entire lifecycle work properly:

create → encrypt → store → edit → local sync → cloud sync → restore

Alongside that, I shipped:

📝 Rich-text Encrypted Notes

🎞️ Slideshow Viewer

🌍 German + Vietnamese

🔢 Stealth PIN Recovery

🖼️ Animated GIF playback

👨‍💻 About the Dev / roadmap

What's crazy to me is how different Lockify is from what I originally imagined.

A lot of the roadmap has been shaped by actual users rather than my original plans.

Still building it solo. Still working on it after my day job.

Six months in, and I still feel like I'm just getting started.

I got tired of PDF sites that want an account to merge two pages, then keep the file around.

So I built SoHappyPDF. You open one tool (merge, split, compress, convert, protect), drop a file, download the result. No account for basic use.

Files are temporary on purpose. They expire after about two hours. Not a document library.

Free is small: 5 operations per day, 25 MB. Pro is $5/month.

I'm the founder. Roast the UX if you try it.
