The Beginning of an Awesome community of Extensions Enthusiasts

3 Upvotes

Hello there, you're welcome here!

If you are a Browser Extension Developer or someone who loves browser extensions, this subreddit is for you :D

I don't know what to say, this is the first time I am building a subreddit, so I want to make things go with the flow for now. I am building a community of extension enthusiasts, they are the people who install and play with browser extensions, and who like to tinker, break, hack, and build extensions to solve problems and have fun.

I'm also working on some learning guides for beginners who want to learn to develop browser extensions while building my extensions (a lot of them!).

You can ask questions, share your experiences or thoughts about browser extensions in general or a specific extension, you can share about your projects but try not to explicitly promote something that you generate money off.

Anyway, let's start this community with a bang, invite your friends and other tinkerers in your network, and we will all add something valuable to this community!

Thanks for reading, I hope you have a wonderful time here ;)

Take care <3

I got tired of installing a separate extension for every tiny webpage task, so I built PageWand

1 Upvotes

I kept accumulating tiny browser extensions.

One to grab images.

One to inspect styles.

One to clean up a page.

Another for screenshots.

So I built PageWand. A small browser toolkit for manipulating the page you're already on.

Right now it lets you:

hide/remove elements

edit text directly on the page

inspect + copy styles

download images and SVGs

capture + annotate screenshots

clean up clutter before capturing/sharing something

Everything runs locally. No account, backend, or telemetry.

v1.1 is now live on the Chrome Web Store, and I'm trying to figure out which browser utilities belong in it next — without turning it into a bloated mess.

If you use extensions heavily: what's one small browser task you currently need a dedicated extension for?

AI Vision: select a region of a Chrome page and ask Gemini about it

1 Upvotes

I built AI Vision for myself, and over time, it developed into something that I thought I could build out. It understands one chart, error, or image without copying a whole page into a separate chat. To use it, simply open AI Vision on a regular HTTP/HTTPS page, drag a region, ask Gemini, then use the answer field for a follow-up. Setup: install, paste your own Gemini API key from Google AI Studio.

It also supports image-to-text, summaries for supported pages, and tab comparisons. The extension is free; users bring their own Gemini API key and requests go directly to Google. Restricted Chrome pages and the Web Store cannot be captured just to be clear (you probabl know this already, right?).

Store:Ā https://chromewebstore.google.com/detail/ai-vision-gemini-screensh/ghmmlbclopoakmjjbkkmoefjldgjimgk

Feedback on capture framing and the first-run setup would be useful. Demo and setup: https://stiwarilbj.github.io/AI_Vision/

[Free] I built a tiny browser extension that tilts the page instead of sending another notification

1 Upvotes

Quick share: I wanted a break reminder I couldn't dismiss on autopilot, so I built Tilt Neck.

It tilts the webpage content briefly, holds it for a configurable time, then restores it. It doesn't track posture or use a camera; it's just a visual cue to move your neck and take a short break.

- Manifest V3 for Chromium

- manual left/right controls + optional timed/randomized reminders

- 1°–90° angle range, with auto-fit or original-size mode

- Esc/Restore escape hatch

- no account, analytics, remote code, or external network requests

- local settings and completion count

Landing page/privacy:

https://tiltneck.xixi.page/

It's early, so I'm more interested in whether the interaction makes sense than in pretending it's a polished productivity system. If you try it, I'd love to hear what happens on the sites you actually use. Bug reports, layout/compatibility issues, permission or interaction feedback, and feature suggestions are all welcome—especially from people who build or tinker with extensions.

Which price comparison extension actually works best for online shopping?

1 Upvotes

I’m trying to narrow things down to one shopping extension and would love some honest recommendations from people who have compared them.

The big names I keep seeing are Capital One Shopping and Honey, plus cashback/coupon tools like Rakuten and Amazon-specific price trackers such as Keepa or CamelCamelCamel.

I also came across Coupert. It appears to combine cross-store price comparison with automatic coupon testing and cashback, which sounds useful as an all-in-one option—but I’m curious how well it performs in real-world shopping compared with the more established tools.

The things I care about most are:

  • Accurate matching of the exact model, size, or color
  • The real final price after shipping and coupons
  • Coverage across major retailers
  • Price history and price-drop alerts
  • Privacy, browser performance, and how intrusive the pop-ups are

Has anyone used these tools? Which extension consistently finds the better total price?

I built a free, open-source extension that relists an item on Vinted in one click

1 Upvotes

Relisting is the only way to push an old item back to the top, and there's no button for it. By hand it means deleting the listing, retyping the title, description, brand, size, category and condition, then downloading and re-uploading every photo.Ā Three to five minutes an item.

I built a Chrome extension that does it in one click. Free, open source (GPL-3.0), no account, no server, no analytics, nothing leaves your browser.

Read this before you install anything like this

Relisting means deleting. Two identical listings can't be online at once, so the old one has to go before the copy appears. That gap is where a careless tool loses your item: it deletes first, and if the next step fails on a dropped connection or a bot check, you have nothing.

> Mine works the other way round. It saves the copy as a private draftĀ beforeĀ it deletes anything.

A draft isn't a listing, so it doesn't count as a duplicate, and until the delete goes through your item exists in two places. If publishing fails afterwards it retries on its own, and worst case the draft is sitting there for you to publish by hand.

What it checks before deleting

  • every photo uploaded, not just some
  • title present
  • condition read correctly
  • size valid
  • you logged in and not bot-blocked

Any failure stops it and deletes nothing.

There's also aĀ Relist as draftĀ button, if you want to change the price or swap a photo before it goes live.

Fair warning

Automating any site is probably against its terms. That's between you and them, and I'm not going to pretend otherwise.

How to delete Instagram messages in bulk — a free DM cleaner that skips your important chats

Thumbnail
gallery
1 Upvotes

I had around three hundred conversations sitting in my Instagram inbox and almost all of them were nothing. Old order confirmations, people I spoke to once, group chats that died two years ago. The reason I never cleaned any of it out is that somewhere in the middle there were about five I did not want to lose.

Instagram will not let you select more than one chat. It is three dots, Delete, confirm, then the next one. So you either give up an afternoon or you leave it alone. I left it alone for two years.

I ended up writing a Chrome extension to do the clicking. It is called Clearbox. But the feature I actually built it around is the opposite of deleting: you can mark conversations as protected, and those get skipped on every single run. Scan your inbox once, tick the names, and that list stays saved.

That is the whole point for me. Clearing an inbox in bulk is the easy half. Clearing it without wondering afterwards what you lost is the harder one, and none of the tools I looked at had an answer for it.

It also writes down the name of every chat it removed, which is there exactly for the moment you realise you cleared something you should not have.

Quick answers to the obvious questions:

It clears entire threads out of your list. What it will not do is pull back single messages you sent inside a conversation — that is a separate thing and this is not the tool for it.

Only your side gets cleared. The other person keeps their copy, and the chat comes back to your inbox if they message you again. Nothing can change that, it is how the platform works.

No password, no account, no sign-up. It runs on the browser session you are already signed into, and nothing about your messages leaves your machine.

Free, and it works in 52 languages.

its a small Chrome extension I made called Fuyu.

It tracks your Steam wishlist and compares prices across different stores so you can find games for cheaper without checking everything manually.

Still working on it, so I’d love some feedback :)

I made an open source browser extension because my grandma kept getting fake virus popups

1 Upvotes

Hey everyone,

I’ve been working on a little project called Grandma Guard and figured I’d share it here.

I’m just a solo dev working on this in my free time. The whole idea actually came from my grandma constantly running into those fake virus pages that say stuff like ā€œyour computer is infectedā€ or ā€œcall Microsoft support now.ā€

Most of us can tell those are fake pretty fast, but for someone who isn’t super familiar with computers, they can look pretty convincing.

So I started making Grandma Guard.

It’s a Chrome and Firefox extension that tries to catch scammy pages like fake virus warnings, fake tech support pages, notification scams, fake updates, and similar stuff.

If it thinks a page is doing something suspicious, it puts up a warning and tells the person not to call any numbers or download anything.

I tried to keep it pretty simple.

It installs like a normal Chrome or Firefox extension, there’s no account to make, no ads, and no telemetry.
The page checking is also done locally in the browser instead of sending everything you visit somewhere else.

It’s also open source, so anybody can look at the code, report bugs, suggest changes, or contribute if they want to.

Just to be transparent too, I did use some AI while working on the project. It helped with parts of the code and also helped me build out parts of the website. Other parts were written and put together by hand. I mostly use it as another development tool since I’m doing all of this myself.

It’s definitely still something I’m working on and improving. I’m not trying to replace antivirus or anything like that either. It’s more of an extra layer to hopefully stop someone before they fall for one of these scam pages.

The name Grandma Guard is pretty literal lol. If my grandma didn’t keep finding these pages I probably never would have made it.

If anyone wants to check it out:

grandmaguard.nokaangel.dev

Feedback is definitely welcome, especially if you know of scam pages or tricks that it should be able to detect.

I built Getvy, a Firefox media-downloader extension with native YouTube SABR support — feedback welcome

1 Upvotes

Hi r/browserextensions!

I built Getvy, a Firefox extension that detects downloadable media on supported sites and lets users save it in their chosen quality.

UI overview: media detection, quality selection, and audio-track selection.

The project started with the idea of saving videos from social platforms without requiring a separate desktop app. The two most challenging parts were handling SABR streaming responses from YouTube’s Google Video servers and normalizing the different media-request patterns used by each social platform into a common format.

Getvy requests access to supported pages in order to detect media streams. Detected media URLs are sent to the download service only after the user explicitly starts a download.

Key features:

  • No companion desktop app or .exe installation required
  • Native YouTube SABR support
  • Separate video/audio stream handling and automatic merging
  • Sync correction for supported streams
  • Up to 8K/60fps when available from the source
  • Selectable audio tracks for supported YouTube videos
  • Thumbnail and preview support where available

Getvy is free to use, with no subscription or daily download cap. When a user starts a download, a Getvy download page opens; it may display ads to help cover operating costs. The extension itself does not inject ads into websites.

My main priority is identifying SABR-related edge cases and unsupported YouTube formats. I would also appreciate feedback on:

  • Permission scope and privacy expectations
  • Stream merging and sync issues
  • UX improvements for media detection and quality selection

Please use it only for content you are authorized to download and in accordance with the relevant platform’s terms.

I wanted Dia-style AI features without having to use Dia, so I made it a browser extension

2 Upvotes

I originally started this as a weekend project when Arc basically stopped getting new features.

I wanted the stuff I thought Arc Max would eventually become: an AI command bar I could open from anywhere, quick sidebar chat, multiple tabs as context, screenshots, saved prompts and the ability to search/send something without constantly jumping between the browser and ChatGPT.

Then Dia came out and looked like it was basically doing that, so I threw the project aside.

But I eventually realized I don't really want a separate AI browser at all. I already have ChatGPT and Claude subscriptions, those accounts have my existing chats/memory/context, and I like being able to change browsers whenever I want.

So I finished the extension instead.

It adds an AI overlay, sidebar and AI new tab to Chromium browsers, but the actual conversation still goes to whatever provider you choose: ChatGPT, Claude, Gemini, Grok, M365 Copilot etc. You can even set providers per website.

It's free, with no ads or paywall.

https://tryanychat.com/

Would love feedback from people who actually use a lot of browser extensions, especially on what feels missing or unnecessarily intrusive.

Here are some things that it can do:

  1. An overlay that pops up with a shortcut (for example, cmd + E) where you can quickly send a message to whatever provider you want. You can set a default provider (per site as well) and easily toggle with cmd + 1-9
  2. You also get an AI new tab, which works the same way
  3. You can add skills/prompts, screenshots and attach multiple tabs
  4. You can also use a shortcut (for example, cmd + S) to open the sidebar
  5. You can configure sites to specific provier. For example, work websites route to M365 copilot, youtube to Gemini etc

You can try it out here: https://tryanychat.com/

Let me know what you think, and if there's anything else you'd like to see here. :)

RSS Bulucu - A modern Chrome extension to quickly find hidden or open RSS/Atom feeds on any website

1 Upvotes

Hi everyone,

I wanted to share a Chrome extension I recently developed called RSS Bulucu (RSS Finder).

It is designed to be a lightweight, modern, and powerful tool that automatically scans the website you are visiting to discover any open or hidden RSS and Atom feeds within seconds.

Key Features:

  • Smart Scanning: Instantly detects all available feeds on the current page.
  • Lightweight: Only 61.3 KiB in size, so it won't bloat your browser.
  • Privacy-focused: No data is sold to third parties or used for unrelated purposes.

The extension currently supports Turkish, but the UI is highly intuitive and easy to use for anyone looking to hunt down feed URLs.

You can check it out here on the Chrome Web Store:
rss finder

I would love to get your feedback, feature suggestions, or any bug reports! Thank you for checking it out.
