I built FaceGate — World's first macOS app locker with on-device Face Unlock (Open Source)

If you hand your laptop to someone for a few minutes, they can still open Messages, Photos, Notes, Mail, WhatsApp, browsers, password managers, and other personal apps. I wanted a way to protect specific applications without constantly locking my entire Mac.

I looked around for solutions, but most were outdated, paid, abandoned, or didn't feel native to macOS.

So I built FaceGate.

FaceGate is a native macOS app that lets you lock individual applications and unlock them using Face Unlock, Touch ID, or a password.

A few things I focused on from day one:

  • Everything runs locally on your Mac
  • No cloud processing
  • No accounts
  • No telemetry
  • No subscriptions
  • Fully open source

Features:

• Face Unlock powered entirely on-device using Apple's Neural Engine - little impact on cpu and gpu resources.
• Fast authentication with very low memory and CPU usage
• Liveness detection to prevent photo and video spoofing attacks
• Touch ID and password fallback
• Per-app unlock timers
• Automatic re-lock on sleep, wake, or screen lock
• Custom schedules for automatic lock/unlock periods
• Tamper protection that prevents FaceGate from being quit, disabled, or uninstalled without authentication
• Runs quietly from the menu bar with minimal system impact.

The entire project is written in Swift and designed specifically for macOS.

This is still actively being developed, and I'd genuinely love feedback from Mac users.

Some questions:

  • Is app-level locking something you've wanted on macOS?
  • Which apps would you personally lock?
  • What security or privacy features would you like to see added?

Website: https://facegate-applocker.vercel.app/

GitHub: https://github.com/dweep-desai/FaceGate-Mac

If you think I did a good job, please feel free to leave a star on my github repo - means a lot to me.

Feedback, feature requests, bug reports, and contributions are all welcome. I'd love to hear what you think.

Built a task manager that adapts to fast moving teams

I’ve always hated how every hackathon or side project starts the same way: a new WhatsApp group, links buried in chat by day two, and one person updating a Google Sheet while everyone else ghosts. It’s not a huge problem - just one of those small, recurring annoyances that add up.

I spent 3 months testing why this keeps happening. Turns out, the friction isn’t just the tools; it’s the onboarding. Meta’s WhatsApp API, signups, workspaces, and inviting teammates? That’s a lot for a team that might only exist for a weekend. And honestly, we didn’t need Notion or Jira. We just needed a way to turn "update in chat" into "task on board" automatically. So, I built Euclis.dev - a real-time productivity platform for small teams that adapts to how you actually work. No forcing everyone into a new app. No friction. Core idea: 1:1 WhatsApp assistant per person that turns your messages into a shared kanban, plus a web dashboard for assets/whiteboard. No forcing everyone into a new app.

It’s still rough. I’ve been testing with a few teams and in general got the feedback that it is genuinely useful to people.

Would love feedback from people who run hackathons/side projects:

- What’s the dumbest thing about how teams collaborate right now?

- If you could wave a wand, what would make team coordination 10x easier for a 2-day sprint?

Happy to share what I built if anyone wants to poke holes in it!

I developed Weather World because I wanted a simpler, more helpful way to stay ahead of the forecast. I truly believe that a weather app should be a tool that makes your life easier, not a source of distraction with ads and confusing menus.

How it helps you: The core of the app is all about visual clarity. I’ve focused on creating intuitive graphs that let you see temperature shifts and precipitation trends at a single glance. Instead of reading through long lists of numbers, you can visualize exactly how your day will unfold. It’s minimalist, lightweight, and built for speed—perfect for anyone who values a clean Android experience.

I’d love your support! Please give it a try and see if it helps your daily routine. If you find it useful, please recommend it to your friends! As a solo developer, your support and word-of-mouth are what help me improve and grow.

In compliance with the community rules, I’ve shared the link via IndieAppCircle. Check it out there and let me know what you think!

After 3 failed startups, I finally understand what customer discovery actually means

Three startups. Three times I built something people said they wanted. Three times they didn't actually buy it.

The pattern was obvious. I was asking "would you use this?" and collecting yeses like they meant something. They didn't.

The problem is structural. When you ask someone if they'd use a product, they're predicting their future behavior. Humans are awful at this. We're biased toward yes because we don't want to be negative, and the cost of saying yes is zero, they're not actually committing to anything.

Contrast that with asking about behavior that already happened. "How do you handle this today?" Nobody can lie about what they're already doing. That's real, verifiable behavior.

These are the five questions I run through every customer discovery conversation now:

- How do you solve this today? → Your actual competition

- What's the most frustrating part? → Your positioning, in their words

- What does it cost you? → Whether there's a business here

- What have you already tried? → Active seekers vs. passive complainers

- What does ideal look like? → The outcome they want, not the feature they imagine

The third question is probably the most important. If someone can't tell you what the problem costs them, in real time or real dollars, it's probably not painful enough to pay to fix. That's the filter that saves you from building vitamins.

I now do a minimum of 25 conversations before writing a single line of Vibecode. At around conversation 15-20, you start hearing the same language. The same metaphors. The same workarounds. That's when you know you've found something real.

One thing that changed how I listen: I stopped pitching. Most founders do "discovery" where they pitch for 15 minutes and ask for feedback for 5. That's backwards. You should be quiet 80% of the time.

What's the question you've found most revealing in these conversations?

let's self promote, what are you working on this weekend

Working on FeedbackQueue, a free to use feedback-for-feedback platform for founders to get feedback and testers without, commenting, posting, DMing, SEO, ads, or doing any marketing bs. Not even looking for them.

958 founders already, building our way to 1000 users. (hopefully before Monday)

welcome to the queue, guys.

ConvertKit was 3 months from dying at $1,300/month. The founder sent 100 emails by hand and 10% converted. Here's why that number is insane.

This post is from the series of "How founders got their first 100 Customers"

Most founder including me would've quit in this situations, but Nathan Barry wrote emails.

Not templates or Not "Hey, loved your content." He made a list of every blogger he genuinely respected, actually read their stuff, and wrote 100 completely individual emails each one referencing specific posts, specific ideas. The kind of email where the person receiving it thinks "he actually read my work."

Then he made one offer that changed everything:

"I will personally migrate your entire email list from Mailchimp to ConvertKit. You don't have to touch anything."

Because the real reason people don't switch tools it's not price or features. It's the terror of moving 40,000 subscribers and breaking everything. Nathan said: that's my problem, not yours.

10 out of 100 said yes.

That's 10%. Cold email to paying customer industry average is 0.5-2%. He hit 5x the top of that range. Not because he had a better script. Because the emails weren't cold, they were researched, specific, and came with a concrete removal of the 1 reason to say no.

The growth after:

  • Start: $1,300 MRR
  • 6 months: $15,000 MRR
  • 12 months: $98,000 MRR
  • 24 months: $625,000 MRR
  • 2022: $30M+ ARR
  • VC raised through 2019: $0

this is the learning we all reddit founder should learn it, those 10 customers were bloggers. Bloggers with audiences of other bloggers. They wrote "I switched from Mailchimp to ConvertKit and here's why." Their readers trusted them. ConvertKit spread through creator communities without spending a dollar on ads.

The 10 customers was not just revenue. They become the distribution channel for the next 1,000 customers. most founders i have seen including me would have sent the 100 template emails, would have got 0 response and many of us may concluded that cold outreach doesn't work.

Nathan sent 100 personal emails and got 10 customers and a $30M company.

The channel (Nathan and we have) was the same. The effort per email was the entire difference.

What's the biggest lie in SaaS that everyone still pretends is true?

I've been building and hanging around SaaS for a while, and it feels like there are a lot of "accepted truths" that nobody questions anymore.

Some examples:

"Build in public." "Just solve your own problem." "You need Product Hunt." "Launch fast and iterate." "AI is replacing SaaS." "You need VC funding to win."

Some of these worked... years ago.

Today it feels like the game has changed. Distribution matters more than product. SEO is getting replaced by AI search. Everyone can build. Very few people can sell.

So here's my question:

What's one piece of SaaS advice that you think is complete BS in 2026?

Or what's a lesson you learned the hard way that nobody talks about?

I'm genuinely curious whether people are seeing the same shift or if I'm just spending too much time on Reddit.

What's the most expensive infrastructure lesson you've learned the hard way?

Learned this one the painful way.

Heroku rotates DATABASE_URL during certain maintenance events.

If you've hardcoded that value anywhere instead of reading it from the environment, your app can randomly stop talking to the database after maintenance.

Nothing's "broken."

Your code is.

It's one of those infrastructure gotchas you only learn after losing a few hours debugging.

What's the most expensive infrastructure lesson you've learned the hard way?

Mine was this.

What's yours?

Introducing LeakScope: A Security Scanner for Supabase Applications

Introducing LeakScope, again.

we've been updating it : )

LeakScope is a security scanner built for Supabase applications. Paste your app's public URL, and it checks what an attacker can learn from the outside—from exposed keys and public data access to weak RLS, leaked credentials, and insecure frontend configuration.

We've introduced two scanning modes:

Light Scan — Paste a public app URL to instantly check for exposed keys, public data exposure, leaked credentials, weak RLS, and risky frontend configuration. No account required.

Deep Scan — Authenticate to validate Row Level Security, test BOLA/IDOR, analyze JWT security, and generate detailed reports for real security validation.

Whether you're a solo founder, indie hacker, or vibe coder shipping MVPs at 2 AM, LeakScope gives you a fast way to see what your app is exposing before everyone else does.

1,936 websites scanned.
13,679 security findings identified.

I made an Android app to track and manage your 3D printing filament inventory using NFC (SpoolTap)

Hi everyone,

I wanted to share an Android-exclusive app I’ve been developing called SpoolTap. It’s designed specifically for 3D printing hobbyists who want a faster, more reliable way to manage their filament inventory without relying on messy spreadsheets or locked proprietary ecosystems.

💡 What is SpoolTap?

SpoolTap turns your Android phone into an NFC-based filament scanner. Instead of manually typing in weights and material types every time you swap a roll, you can log, update, and check your inventory with a single tap.

✨ Key Features & Benefits

  • NFC Scanning for Supported Spools: Directly read and log data from filament manufacturers that already embed NFC tags in their spools.
  • Custom NFC Tag Writing: If you use standard third-party spools, you can write and link your own inexpensive NTAG stickers to any spool in your digital inventory.
  • Comprehensive Inventory Management: Keep a clear overview of your materials (PLA, PETG, ABS, etc.), exact colors, remaining weights, and manufacturer details.
  • Native Android Experience: Built from the ground up to feel fast, modern, and intuitive on Android devices.

🎯 My Feedback Goals

As I continue to refine the app, I am looking for constructive feedback from the community on two specific areas:

  1. NFC Compatibility: If you use spools with built-in NFC tags, how does the reading experience feel, and are there specific manufacturer tags you'd like to see better supported?
  2. Workflow & UI: Is the process of adding a new spool and updating its remaining weight quick enough for your daily printing workflow?

🚀 Download

SpoolTap is available on the Google Play Store: 👉Get SpoolTap on Google Play

Thank you for reading, and I look forward to your thoughts and constructive feedback!

We really don't need to fundraise as startups anymore (i will not promote)

You're fundraising cuz u need resources to either launch or scale your startup.

But those same resources you're bending over backwards for, are actually all around you already (for the most part)

You just have to ask yourself, "do u have to own the resource, or do u just need access to it?"

Many many startups have fundraised to acquire the resources you need.

What if u could just access those instead?

Through collaborations.

And it gets better.

Rev-share collaborations.

Access them, and pay only with the revenue they help you generate.

Shall we call it "resource financing"?

I wanted to share this because I have 10 of these myself.

I have a platform, I own 100% equity, paying $0 upfront, and we're growing 67% per month thanks to these collaborations.

I have help with development, I have help with operations, and a lot of help in distribution.

It's really hard to set up, so I'll be happy to help anyone interested in exploring this strategy.

Happy Sunday everyone! What are you buidling today?

Hey all, hope you’re having a great weekend!

Just wanted to share a quick milestone: Our startup, NextIsOnMe (NIOM), officially crossed 500 real-world events hosted across 118 cities! 🌍

For context, NIOM is an offline social network operating in high-density metros. The hook is simple: a venue or host covers the bill to remove the financial friction of meeting new people in real life.

Our biggest takeaway getting to this point? Digital ads are a trap for early B2B onboarding. We stopped burning cash on digital acquisition and shifted entirely to a "concierge service", using boots-on-the-ground team members to physically walk into cafes, build trust, and manually onboard them. It completely unlocked our growth loop.

We’re staying lean, self-funded, and focused on clearing our tech backlog this week.

But enough about us, what are you working on today? Drop your project, a recent win, or a roadblock you're trying to smash through. Let's talk shop!

Building in public

Hey everyone!

I'm currently developing three different tools and I'd love to get your perspective on which one has the most potential.

  1. Trading Bot (Swing Trading)

I've built an automated swing trading bot and ran backtests on 2 years of historical data. Currently sitting at a 56% win rate on profitable trades. It's a solid foundation, but I'm wondering if there's real market demand or if it's too saturated.

  1. Automated Blog Generator (WordPress Plugin)

This one automatically creates blog content from sources you provide. It generates articles and publishes them completely autonomously—no manual input needed. I'm planning to adapt it as a WordPress plugin so users can implement it like any other plugin. Great for content creators and bloggers.

  1. Recipe & Shopping Assistant

The problem: I never know what to cook when I get home, and I always buy the wrong stuff at the grocery store. This tool solves that by creating a smart shopping list tied to actual recipes. It's solving a real pain point in my life.

My question: Which of these would YOU find most useful?

What's missing from the market?

Any feedback on viability, competition, or direction would be super helpful as I prioritize my time.

Building in public and grateful for your thoughts! 🙌
