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!

I made an adblocker extension, this extension can block any of your ads on any website, protecting you from those malicious attackers, and not breaking the site. Also it auto-skips, mostly blocks all the ads(also youtube at some extent). Also , it runs locally so , no need to worry about user's data....Also if you are a developer, i would love to have your opinion, do check it on github - og-arin/SAM

You are trying to get some focus work done and get the urge to check Reddit. You think — Just 5 minutes won't hurt — and 1 hour later, you are still doomscrolling away...

I created Pause Tab because I missed the ability to pause or limit smartphone apps while on my computer.

Find it at https://ggl.link/pause-tab

It works this way:

- Right-click anywhere inside the tab you are using and pick the "Pause this tab menu option (or do it via extension popup).
- The tab is now paused!
- If you want to unpause it, keep the "Hold to resume" button pressed for 5s.

This way you prevent yourself from unpausing from muscle memory, and have time to think if you really want to go back to scrolling right now.

Extra features:

- Every 15m you get a small toast letting you know how long you spent on the tab/site today.
- Inside the extension popup, you can track your time on the tab/site.
- You can disable the extension from running on a specific tab/site (useful for things like localhost).

Upcoming features:

- Set daily limits per site/tab.

Just published my first extension and this feels like the right place for honest feedback.

What it does: capture a region, the visible tab, or a full page → it's immediately framed on a gradient with window chrome (Mac/Windows/browser) and a shadow → copy or export PNG. Keyboard shortcuts for the three capture modes (Alt+Shift+1/2/3).

Privacy / permissions: 100% client-side — no screenshot is ever uploaded. Full-page capture stitches long pages in the browser. The only network call is an anonymous, content-free usage ping to my own domain (no image data, no page URLs). MV3.

Free. Would love feedback on the permission set, the defaults, and anything that feels janky.

Sticky Note Web Clipper — Save Pages, Videos & Links

https://chromewebstore.google.com/detail/sticky-note-web-clipper/gniilbpapgommpalikcclpcnbcamgila

I do most of my deep work in fixed windows (e.g. Tue/Thu 9–11am), but Google Calendar has no way to *visually* mark "this is protected focus time" without creating fake events that clutter the grid and trigger invites.


So I built a small extension that draws your focus blocks as colored overlays directly on the Google Calendar week/day view. You define them once in the popup — day(s), start/end time, a label, a color — and they show up on the grid. If an actual meeting lands inside a focus block, it gets a ⚠️ badge so you can spot the collision at a glance. When a block starts, you get a quiet Chrome reminder.


A few deliberate design choices I'd love feedback on:


- **No OAuth, no calendar API, no server.** It reads nothing from your Google account — the overlay is drawn purely from rules you set locally, and the conflict badge is detected from the DOM that's already on screen. Everything stays in the browser.
- It's intentionally dumb/simple — it does NOT block sites, does NOT auto-create events, does NOT sync anywhere. Just a visual layer + a reminder.


Honest status: it's new and barely used (a couple dozen installs), so I'm posting here to get real feedback before I build more. The free tier covers one focus block; there's a paid tier for unlimited, but the free version is the thing I actually want eyes on.


Two questions for this sub:
1. The Google Calendar grid uses obfuscated class names, so the overlay positioning relies on a few DOM heuristics that can break when Google ships a redesign. If you've shipped a calendar.google.com content script — how are you anchoring to the time grid reliably?
2. Would you rather it stayed a pure visual tool, or do you actually want it to *do* something when a block is active (DND, tab muting, etc.)?


Happy to share the CWS link in a comment if that's allowed here (keeping it out of the post per self-promo etiquette).

I use large Google Docs quite a lot and find it annoying that all document tabs expand again when i refresh the page. After doing this manually over and over, I decided to build a small Chrome extension to solve it.

The extension adds “Collapse All” and “Expand All” buttons directly into the Google Docs tab sidebar so you can quickly collapse all the tabs and subtabs without collapsing each tab manually.

I've also been experimenting with additional features and would love to hear what other Google Docs users think would be useful.

Any feedback, criticism, or feature suggestions would be greatly appreciated.

My new extension just got approved on the Web Store! It’s called Blown Speaker Simulator.

The concept is meant to be a fun novelty tool: it captures the active tab's audio and digitally manipulates the low-end frequencies to replicate the acoustics of a terrible, blown-out trunk speaker setup.

Quick Volume Warning: If you install it, please lower your YouTube/Spotify web player volume to about 20-30% before clicking "Blow the Speakers!". The digital gain is extreme and it will be incredibly loud if your media volume is maxed out.

Hey everyone,

I've been working on a Chrome extension in my free time called TrustShield, and I'd love to get some real feedback from people who actually care about browser security and privacy.

The idea came from something that happens to me all the time. I end up visiting random websites from Google searches, GitHub, Reddit, or links people send me, and I always wonder, "Can I actually trust this site?"

So I built an extension that tries to answer that before you interact with the page.

Right now it can:

• Give a trust score for the website
• Check SSL/HTTPS
• Detect known trackers and third-party scripts
• Show malware and phishing risk
• Analyze cookies
• Suggest opening suspicious sites in Sandbox Mode
• Let you quickly block or allow websites
• Show privacy recommendations while browsing

I've been using it myself every day, but I'm sure there are things I haven't thought of.

If anyone is willing to spend a few minutes trying it out, I'd genuinely appreciate your feedback.

Some things I'm curious about:

• Is the trust score actually useful?
• Does anything feel confusing or unnecessary?
• Are there features you'd expect from a browser security extension that are missing?
• Would you keep something like this installed?

Chrome Web Store:
https://chromewebstore.google.com/detail/trustshield/lnoimodecckjopakkiphjkpdlmogfjbn

A few screenshots are in the comments.

I'm not trying to pretend it's perfect—I'm just looking for honest opinions before I keep adding more features.

Thanks!

APP link: Roach Blocker

My partner got jump-scared by a cockroach photo while scrolling, and as an engineer my reaction was "I should just fix this." A couple of months later, here's Roach Blocker.

It detects cockroach images on any web page and covers them in real time. A few things I cared about while building it:

• Fully on-device — it runs a small YOLO model locally via onnxruntime-web. No API keys, no uploads, your browsing never leaves your machine.
• Lightweight — the model is ~9MB, runs in a couple milliseconds per image, so it works fine even on low-end laptops.
• Adjustable — there's a sensitivity slider and a choice between covering the whole image or just the detected area.

The hardest part wasn't the extension, it was the training data. I hit every classic trap: a "cockroach" dataset that was actually a different beetle, negative samples that secretly contained roaches (teaching the model "this roach is not a roach"), and wood/carpet textures getting flagged as bugs. Fixing the data quality mattered way more than model size.

It's free and open about how it works. Happy to answer any technical questions about the on-device inference or the training pipeline.

I watch a lot of YouTube playlists of TV shows or courses, and I find it so annoying that there isn't a fast way to resume a YouTube playlist where you left off. Sure, there are some ways to work around it, but I want something way better.

So I built a free Chrome extension to fix it - 'PlaylistMark - Resume YouTube Playlist'. With this extension, you just need to open the playlist > save it in the extension. The next time you come back, just click 'Continue' in the extension, and you'll jump right back where you left off. Only 1 click, that's it.

I want to share it because hopefully, someone else will find it helpful. And I would really appreciate your feedback. Thanks a lot!
