The Problem

Tired of Managing Too Many Extensions?

The average power user installs 8-12 extensions. Each one slows your browser, creates conflicts, and fragments your workflow.

Pomodoro Timer with Screen Dim

Focus sessions with auto screen-dimming, session tracking, and break scheduling. A complete replacement for Marinara or Forest extensions.

Notes with Slash Shortcuts

Create notes and trigger instant autocomplete in any text field with custom shortcuts. Like TextExpander built into your browser.

Clipboard History (100 Items)

Never lose a copied snippet. Search, filter by source domain, and reuse anything from your last 100 copy operations.

Habit Tracker

Build daily routines with one-tap check-offs, streak tracking, and progress visualization right in your browser.

Google Calendar Integration

OAuth-powered calendar sync with event notifications. View upcoming events without leaving your browser.

Bookmark Manager

Navigate, search, and organize your entire bookmark library from the side panel with breadcrumb folder navigation.

Combat sedentary work with scheduled standing reminders. Set intervals from 15 to 90 minutes.

Three scheduling modes — interval-based, fixed-time, and date-range — with website exclusion lists.

I replaced 8 extensions with OneBuddy. My browser is faster, cleaner, and I actually remember to drink water now.

The Pomodoro timer with screen dim is genius. Combined with the clipboard history, this is the only productivity tool I need.

Full-Stack Developer

Privacy blur alone is worth it. I can screen share without worrying about sensitive data. The ad blocker is a bonus.

Frequently Asked Questions

Everything you need to know about OneBuddy

Yes, 100% free with no premium tiers, no ads, and no hidden costs. Every feature is available from day one. We believe productivity and privacy tools should be accessible to everyone.

OneBuddy consolidates 10+ standalone extensions into one: Pomodoro timer, ad blocker, tracker blocker, clipboard manager, notes app, habit tracker, screen recorder, privacy blur, bookmark manager, browser lock, and health reminders.
No. OneBuddy is built on Chrome's Manifest V3 with a single lightweight service worker. It's actually faster than running multiple separate extensions because it eliminates inter-extension conflicts and duplicate processes.
Yes! OneBuddy includes separate toggles for YouTube video ads, YouTube banner ads, and general website ads. You can customize blocking per-site with a whitelist for trusted domains.
Privacy Blur lets you click or drag over any element on a webpage to blur it. It supports 5 blur styles (Gaussian, Pixelate, Blackout, Frost, Noise) and persists blurs — they re-apply automatically when you revisit the page.
Yes, all core features work offline. The Pomodoro timer, notes, clipboard history, habit tracker, privacy blur, and browser lock function without an internet connection. Only Google Calendar sync and messaging require connectivity.
Browser Lock overlays a password-protected lock screen across all tabs. It uses SHA-256 password hashing, has a 5-attempt lockout with cooldown, blocks developer tools while locked, and supports auto-lock after inactivity.
OneBuddy supports 40+ languages including English, Spanish, French, German, Japanese, Korean, Chinese, Arabic, Hindi, and many more. The interface automatically detects your browser language.
