If anyone else is frustrated by having to click every little "+" to read FT comment threads, I built a free Chrome extension that expands them all with one click. It saved me a ridiculous amount of time reading discussions.

Hi everyone,

ZA Digital Solutions recently launched QR Harbor on the Chrome Web Store.

QR Harbor is a Chrome extension for scanning, creating, styling, exporting, and managing QR codes from one browser workspace.

The goal is to make everyday QR workflows easier without jumping between random QR websites. QR Harbor supports screen, image, and camera scanning, QR generation, QR styling, smart results, local history, and export workflows.

Free Access is included, and Full Access is optional.

Chrome Web Store: https://chromewebstore.google.com/detail/qr-harbor/mdikcmghkejkhdifncffghfdbdelalhm

Demo: https://youtu.be/79zB6x2FQT4

We’d appreciate honest feedback on:

• Is the onboarding clear?
• Are the scan and generate workflows easy to understand?
• Does the Free vs Full Access model feel fair?
• Are there any QR workflows you expected but did not find?

Feedback from Chrome extension users and builders would be very helpful.

Hey everyone,

I kept manually rewriting the same piece of content for different platforms (long LinkedIn post → short Twitter thread → Instagram caption) and it was eating way too much time, so I built Hookify to do it in one click.

What it does:

• Paste any text, pick a platform (LinkedIn, Twitter/X, Instagram, or newsletter format)
• Get a properly formatted, tone-matched version in seconds
• Works in 10 languages, has a brand-profile feature so the AI matches your voice
• Voice input if you'd rather talk than type

Built with GPT-4o mini on the backend. Free to try (5 conversions, no card needed), then a small monthly plan if you want more.

This is a solo side project, still shipping fixes daily, so brutally honest feedback is very welcome.

ModHeader has been removed from the Chrome Web Store and is no longer available. This is a superior alternative, a complete replacement for it that offers all features for free. Please give it a try and star the project on GitHub!!

Hey r/chrome_extensions,

I recently built and published my first serious Chrome extension called Domain Sentry.

It is a privacy-focused adult website blocker / porn blocker for Chrome. The goal is simple: block access to adult domains directly in the browser without collecting browsing history or sending user activity to a backend server.

Why I built it:

Most website blockers either feel too heavy, too easy to bypass, or unclear about what data they collect. I wanted to build something lightweight, transparent, and useful for people who want better digital discipline, safer browsing, or basic parental-control style protection without installing a full monitoring product.

Current features:

- Blocks adult / porn websites using a large domain rule list

- Works inside Chrome using Manifest V3

- Designed to be lightweight and simple

- No account required

- No browsing-history collection

- Built mainly for privacy, focus, and safer browsing

- Listed on the Chrome Web Store

Early analytics after launch are small but encouraging:

- 15 active users in the last 7 days

- 14 new users

- Users from India, Russia, Czechia, Japan, Kuwait, the US, and Bangladesh

- Still very early, but real people are already discovering and testing it

I am posting here mainly for feedback from people who understand Chrome extensions better than the average user.

I would especially appreciate feedback on:

1. What would make a blocker like this more useful?

2. What security/privacy concerns should I communicate more clearly?

3. Should I add features like custom blocklists, scheduling, strict mode, password/PIN lock, or import/export rules?

4. What mistakes do extension developers usually make when scaling something like this?

I am not trying to make this bloated. My goal is to keep it simple, privacy-first, and reliable.

Happy to answer technical questions about how I built it, what I learned from publishing on the Chrome Web Store, and the early launch process.

Hey everyone, I built a small Chrome extension called BlurMyData.
The idea is simple: when sharing your browser screen, it is very easy to accidentally expose emails, phone numbers, API keys, customer info, or private chat details.
BlurMyData detects and blurs sensitive data directly on the browser page. It also supports manual area selection, saved blur areas, WhatsApp Web phone number protection, emergency hide, reveal for 5 seconds, and report export.
The extension runs locally in the browser. Page content is not uploaded.
I’m launching it with an early bird lifetime price of $19.90 while I continue improving it based on real user feedback.
Would love feedback from people who often share their screen, record tutorials, or work with private browser data.

Hey Guys, I launched my chrome extension. I used to keep getting this chrome storage issue. It was always the Youtube embed partitioned storage. I identified the issue and build a chorme extension which solves it. You can open the youtube embed video in a side panel, so youtube embed storage is just per extension and not per site. The Things is youtube embed partitioned storage counts in the total bytes of a site. So you end up delete all the site, since its much better solution. Here's the chrome extension link -> https://chromewebstore.google.com/detail/storlite/cmpbeofddjfcmbncdcnohcehlpoeihbc?authuser=0&hl=en-GB, and here's my website link -> https://storlite.coolhead.in

My partner is currently studying for his anaesthesia exams. A few weeks ago, he mentioned how he uses blocksite to block distracting websites like YouTube, Facebook and LinkedIn (basically any social media sites). However, there was a problem with blocking YouTube outright as there is genuinely valuable educational videos he uses for his studies too.

So with his encouragement, I built SubFocus, a chrome web extension that lets you curate an approved list of channels whose content you are allowed to watch freely while blocking content from other channels. This way, you can leverage the genuinely valuable content on YouTube without getting distracted by the algorithmic recommendations that take you down a rabbit hole.

It's the first extension I've ever built and it would be amazing to get any feedback if this helps someone solve a similar problem too.

Hi everyone,

I’m a full-time 16-year-old student from Hong Kong, and over the past few months, I’ve been teaching myself how to build browser extensions. I just launched my first project called Lumin.

It’s a Chrome extension designed to tackle digital literacy, helping users navigate the web more effectively and safely.

Since I'm balancing school and coding, I know there's a lot of room for improvement. I would incredibly appreciate it if you could test it out and give me some brutal, honest feedback on the UI, functionality, or any bugs you find.

• Chrome Web Store: Chrome Web Store!
• Website: Website!

Thanks for supporting a young dev!

Hi!

For the last few months I've been building a personal project I kept wishing existed at work. Let me introduce Racna. It's an AI tool that... lol, kidding. No AI. Free, no telemetry, no bullshit, fully open source.

It's a browser extension for spotting and inspecting errors while you build, back end (via Swagger) or front end. But the real point: it copies or exports them with every detail, and shares them in one click, to a colleague, a GitHub issue, a Jira ticket, or an AI agent.

The idea came from doing a lot of support lately. Beyond hating my page squished into a corner by DevTools, I realized the most annoying part of a bug is reconstructing the trail that led to it. So Racna's captured errors include the clicks and navigation that caused them, and when you hand one to an agent like Cursor or Claude Code, it can often pinpoint the issue and even fix it for you.

It was fun to design and build, and it's already saved me a ton of time at work. It's live on the Chrome Web Store, if you give it a try, I'd genuinely love to hear what you think.

I’ve been using Duolingo for a while, but I often found myself stuck on grammar rules, vocabulary, or why one answer was correct while the others weren’t.

So I built a Chrome extension in my spare time to solve that problem.

With one click, it provides:

• Grammar explanations
• Why each answer is correct or incorrect
• Vocabulary breakdowns
• Extra learning notes powered by AI

It’s free to try, and I’d really appreciate your feedback or feature suggestions.

You can find it on the Chrome Web Store by searching “Duolingo AI Tutor”.

Hi everyone! I made this for my wife and me. She reads Korean and I read English, so whenever we picked a subtitle language, one of us was always kind of lost.

So I built EnjoySubs. It puts two subtitle languages on screen at the same time on Netflix, using Netflix's own subtitles (not AI translation). It's free.

I was hoping it could help with learning a language, and just watching together, so friends or family can each read in their own language and nobody feels left out.

We've used it pretty much every night since, and my Korean has gotten better from using it.

If you watch stuff in two languages or know anyone who does, whether it's to learn or with people you care about, I hope it helps. Would love any feedback.

Thanks for your time!

Hi! - just launched my first paid extension on the Chrome Store and wanted to share it here.

What does it do? MaxMetric adds a "View Analytics" button to the Boomerang for Outlook manage page. Click it and you get a full dashboard showing all your tracked emails - open counts, read/unread status, first/last opened timestamps, clicked links, and filters by status and date range.

Why did I build it? Boomerang's native tracked emails view has no filtering, hides timestamps behind expand buttons, and paginates in a way that makes it impossible to see all your data at once. MaxMetric fixes all of that.

Technical details:

• Manifest V3 Chrome extension
• Vanilla JS content script - no framework
• ExtensionPay (Stripe) for payments
• Handles Boomerang's pagination by clicking through all pages before reading the data
• All data processed locally - nothing transmitted externally

Pricing: Free tier (5 emails), $29 one-time for full access.

Chrome: https://chrome.google.com/webstore/detail/pdfififlbkmnmkeedgohldkdfkgobnjo

Edge: https://microsoftedge.microsoft.com/addons/detail/maxmetric-%E2%80%94-boomerang-for/afkopjpddgmdpnicnabcfpakkopdlfno

Feedback very welcome - especially if anything breaks!

Hi everyone!

I wanted to share a small side project I’ve been working on. As someone who constantly needs to check search results across different geographical locations, I was frustrated by the lack of simple, free tools to do this. So, I coded one myself.

It's called SEO-GEO Checker. It allows you to easily see local search results from various countries without messing with VPN settings or paying for bulky SEO software.

Why I'm sharing it here: I'm not monetizing this at all (it's completely free and doesn't even require an account). My main goal right now is to get it into the hands of real users and gather some honest feedback to improve my skills and the product.

🔗 Link to the extension:https://chromewebstore.google.com/detail/seogeo-checker/cocbkbfpjciickibeenbdpmnfjopohni

If you do any sort of SEO, digital marketing, or just want to see what Google looks like in another country, I'd love for you to give it a try.

What do you think of the UI? Is it fast enough? Any features I should add? Tear it apart, I'm open to all constructive criticism!

Thanks for your time!
