I Built a Suite of Privacy-First Browser Extensions β Here's Why

Hey devs π
Iβm Arun, an indie maker and software engineer from India. Over the past few weeks, Iβve been building something called HashPal Labs β a growing collection of free, open-source, privacy-respecting browser extensions.
π§© Why I built HashPal Labs
As a developer, I often needed quick tools: a JSON formatter, a voice recorder, a to-do list, or a metadata inspector. But most of the tools I found were either:
Bloated with ads or trackers
Hidden behind paywalls
Required logins for simple tasks
I thought: What if these tools were lightweight, offline-first, and just worked?
So, I started building them β one by one.
π§° What's inside HashPal Labs?
Here are some of the extensions currently available:
π Web Detective β View a siteβs tech stack, meta tags, headers, and more
π JSON Formatter β Cleanly format and collapse JSON for easier reading
β Email Validator β Instantly check if an email address is valid
π Scribbler β A simple, offline-friendly note-taker
π Voice Recorder β Record voice and save it locally
βοΈ To-Do List β A lightweight task manager with no sync, no login
π§ Email Capture β Extract all visible emails from the current page
π Spreadsheet Viewer β Load and view spreadsheet files right in the browser
β¦and more are in the pipeline!
π‘ Core values
Zero Tracking: I donβt log anything. All tools run locally in the browser.
Open Source: Every tool is on GitHub. PRs welcome!
No Ads. No BS. Just simple tools that do their job well.

π Whatβs next?
I plan to keep growing HashPal Labs with community input. Got an idea for a simple browser tool? Drop it in the comments! π‘
Thanks for reading β and if any of these tools help streamline your dev workflow or daily browsing, Iβd love to hear about it.
Cheers,
Arun
