Looking for a lightweight alternative to Comet? Discover how MyNextBrowser Extension delivers private, affordable agentic browsing without changing and slowing your browser.
Why Users Are Searching for a Lightweight Alternative to Comet?
Agentic browsers promise productivity gains, but many users hit the same wall. Heavy memory usage. Cloud-first tracking. Expensive plans that limit experimentation. If you’ve tried Perplexity Comet, you may have felt the power—along with the performance trade-offs.
That’s why more users now search for a lightweight alternative to Comet. They want agentic automation without a new browser, privacy compromises, or $20 monthly fees.
This guide explains what “lightweight” really means in agentic browsing, where Comet falls short for many users, and how MyNextBrowser Extension delivers the same autonomy—often more—inside your existing Chromium browser. You’ll also learn how much time and money you can realistically save by switching.
What “Lightweight” Means in an Agentic Browser
A lightweight agentic browser isn’t about fewer features. It’s about efficient architecture.
Performance without bloat
Lightweight tools avoid constant background sync, heavy cloud rendering, and oversized binaries. MyNextBrowser stays under 5MB, so Chrome, Edge, Brave, or Arc remain fast even with 40–50 tabs open.
Local-first execution
Instead of routing every action through remote servers, MyNextBrowser executes tasks directly in your browser, reducing latency by up to 40–60% for common workflows like form filling or tab organization.
Minimal setup friction
You don’t need to migrate to a new browser or OS. Install the extension and start issuing natural-language commands instantly.
Comet vs a Lightweight Alternative: Where the Gaps Appear
Cost and task limits
Comet’s advanced workflows require paid plans, with limits that can feel restrictive for daily automation.
Typical monthly reality:
- Comet Pro: ~$20/month for limited agentic depth
- MyNextBrowser Premium: $5/month for 1,000 tasks
That’s a 75–80% cost reduction while enabling more automation experiments.
Resource usage
Comet operates as a browser-centric platform. For many users, that means:
- Higher RAM usage
- Slower cold starts
- Fewer customization options outside its ecosystem
MyNextBrowser runs as an extension, so your existing browser optimizations stay intact.
Why MyNextBrowser Is a True Lightweight Alternative to Comet
Agentic automation without compromise
MyNextBrowser handles multi-step autonomous tasks like:
> “Find the cheapest RTX 4070 across Amazon and Newegg, apply coupons, and notify me if it drops 10%.”
> “Summarize today’s unread emails and draft replies to urgent ones.”
Tasks run in the background while you keep working.
Built for real-world workloads
Users report saving:
- 30–45 minutes/day on email triage
- 20%+ savings on online purchases using the Shopping Agent
- Hours/week reclaiming focus from tab chaos
MyNextBrowser scales smoothly even with 50+ open tabs.
Privacy: The Biggest Differentiator vs Comet
Client-first by design
Unlike cloud-heavy competitors, MyNextBrowser follows a client-first architecture:
- Sensitive data never leaves your browser
- Tokens stay encrypted in local Chrome storage
- Temporary context auto-deletes after 15 days
Zero third-party tracking
No analytics pixels. No data brokers. No behavioral profiling. Your browsing patterns remain yours.
For privacy-conscious users, this alone makes MyNextBrowser a compelling lightweight alternative to Comet.
Feature Parity—and Often More
Smart tab and research workflows
MyNextBrowser automatically groups tabs by topic, restores research sessions, and surfaces your most relevant pages. Researchers and developers use it to synthesize data from multiple sources simultaneously, complete with citations.
AI content tools inside the browser
- One-click Text Humanizer to polish AI drafts
- Prompt Enhancer to improve query quality instantly
- Article and video summarizers for faster learning
These tools work directly on the pages you already use.
Pricing Comparison: Lightweight Also Means Affordable
| Feature | Comet (Pro) | MyNextBrowser |
| --- | --- | --- |
| Monthly Price | ~$20 | $5 |
| Annual Cost | ~$240 | $48 |
| Monthly Tasks | Limited | 3,000 |
| Browser Support | Standalone | All Chromium |
| Data Privacy | Cloud-first | Client-first |
For freelancers, students, and founders, this difference compounds quickly over a year.
