Arc Browser changed how people think about browsing. Its Peek feature — a quick preview that slides in from the right when you hover a link — is genuinely clever. It feels native, it looks beautiful, and it solves the same problem GoPeek does: stop opening tabs for every curiosity click.
But Arc Peek has a ceiling. It is built for Arc's specific design philosophy — minimal, opinionated, and locked to one browser. GoPeek takes a different approach: maximum flexibility, cross-browser support, and features that Arc simply does not offer.
If you are an Arc user wondering whether to stick with Peek or switch to GoPeek, this comparison is for you. We will look at what each tool does well, where each falls short, and which one actually fits your workflow.
What Is Arc Browser Peek?
Arc Peek is a native feature of Arc Browser (macOS and Windows). When you hover over a link in Arc, a small preview panel slides in from the right edge of the window. It shows the linked page in a constrained, read-only view. You can scroll, but you cannot interact deeply. It is designed for quick glances — not for actual browsing.
How it works:
- Hover over any link in Arc
- A preview panel slides in from the right
- Scroll to read, move mouse away to dismiss
- Click to open the page fully in a new tab
Arc's design philosophy:
- Minimal by default: Peek is intentionally limited — no navigation, no interaction
- Locked to Arc: Only works in Arc Browser. No Firefox, no Edge, no Chrome
- Read-only previews: You cannot click links inside a Peek, fill forms, or use interactive elements
- No persistence: Peek disappears the moment you move your mouse
What Is GoPeek?
GoPeek is a browser extension that opens links in fully interactive mini-browser windows. Unlike Arc Peek, GoPeek windows are live, navigable, and persistent. You can click links inside them, fill forms, watch videos, and even minimize them into floating bubbles for later.
How it works:
- Hold Shift (customizable) and hover over any link
- A live, interactive browser window opens on your current page
- Browse naturally — click links, scroll, interact with the page
- Double-click the header to collapse into a floating bubble
- Drag to sidebar mode for split-screen research
- Open multiple Peeks side-by-side with Multi-Peek
GoPeek's design philosophy:
- Fully interactive: Peek windows are real browser instances, not read-only previews
- Cross-browser: Works in Firefox, Edge, and soon Chrome — not locked to one browser
- Persistent: Peeks stay open until you close them. Minimize into bubbles. Resume anytime
- Flexible layout: Free-floating, sidebar split-screen, or bubble mode — your choice

Where Arc Peek Wins
Arc Peek is not without merit. In fact, it excels in specific scenarios:
1. Zero-Friction Glances
If you just want to see the headline and first paragraph of a link before deciding to open it, Arc Peek is faster. No modifier key, no deliberate action. Just hover and glance. This is perfect for Twitter, Reddit, and news aggregators where 90% of links are not worth opening.
2. Native Aesthetic
Arc Peek looks like it belongs in Arc. The animation is smooth, the panel matches Arc's design language, and it feels like a native feature rather than an add-on. If you value visual polish and consistency, Arc Peek delivers.
3. No Setup Required
Peek works out of the box in Arc. No installation, no configuration, no learning curve. For casual users who do not want to think about their tools, this is a genuine advantage.
Where GoPeek Wins
GoPeek wins wherever Arc Peek's limitations become friction:
1. Actual Browsing Inside Previews
Arc Peek is read-only. GoPeek is a real browser window. You can click links, fill search boxes, navigate menus, and interact with the page fully. This matters when you are researching — you do not just want to see a paper, you want to use it.
2. Cross-Browser Freedom
Arc is Mac-only (with a Windows beta). GoPeek works in Firefox, Edge, and soon Chrome — on Windows, macOS, and Linux. If you use multiple browsers, switch OSes, or work on shared machines, GoPeek follows you. Arc Peek does not.
3. Persistent Previews
Arc Peek vanishes when you move your mouse. GoPeek stays open. You can minimize it into a bubble, switch tabs, come back, and resume exactly where you left off. This is critical for multi-step research where you need to reference multiple sources over time.
4. Multi-Peek for Comparison
Arc Peek shows one preview at a time. GoPeek lets you open multiple previews side-by-side. Compare two papers, a dataset and a methodology, a product and a review — all without a single new tab. This is impossible in Arc.
5. Sidebar Split-Screen
Arc Peek is a fixed right panel. GoPeek's sidebar mode is draggable, resizable, and can be positioned anywhere. Snap it to the left while writing in Google Docs. Expand it for deep reading. Collapse it when you need space. Arc Peek offers none of this flexibility.
The "Arc Peek Paradox"
Here is the paradox of Arc Peek: it is designed to help you avoid opening tabs, but it is so limited that you often end up opening the tab anyway.
You hover a link. Peek shows you the first paragraph. You want to scroll down, click a citation, or check a figure. Peek does not let you. So you click to open the full page. Now you have a new tab. The exact thing Peek was supposed to prevent.
GoPeek breaks this cycle. Because the preview is fully interactive, you can do your entire research session inside Peeks. Scroll, click, navigate, compare. Only when you are done do you decide whether to open the page in a proper tab. Most of the time, you do not need to.
Who Should Use What
Neither tool is universally better. They serve different users:
| You are... | Use Arc Peek if... | Use GoPeek if... |
|---|---|---|
| A casual browser | You just want quick glances at links on social media and news sites | You want to actually interact with previewed content |
| A researcher | You only use Arc and your research is light ( occasional reference checks) | You need persistent, interactive previews for deep research |
| A multi-browser user | You live entirely in Arc and never switch | You use Firefox, Edge, or Chrome at work and Arc at home |
| A developer | You want minimal distraction and do not need to interact with docs | You need to browse docs, GitHub repos, and Stack Overflow without tab chaos |
| A student | You write papers in Arc's native tools and rarely need external sources | You juggle Google Docs, JSTOR, Wikipedia, and lecture notes simultaneously |
The Portability Problem
There is one more factor Arc users rarely consider until it is too late: what happens when you leave Arc?
Arc is a venture-backed startup. It has raised $17M+ in funding. It is beautiful, innovative, and beloved by its users. But it is also a single product from a single company. If Arc changes direction, sunsets features, or shifts business models, Peek could change or disappear overnight.
GoPeek is an extension. It works in standard browsers that have existed for decades. Your workflow is not tied to one company's roadmap. If you switch from Edge to Firefox to Chrome, GoPeek comes with you. Your muscle memory, your settings, your habits — all portable.
The Bottom Line
Arc Peek is elegant, minimal, and perfectly suited to Arc's design philosophy. If you live entirely in Arc and your browsing is light — social media, news, occasional reference checks — Peek is enough.
But if you research, develop, write, or work across multiple browsers, GoPeek is the fuller solution. It is interactive where Peek is read-only. It is persistent where Peek is fleeting. It is flexible where Peek is fixed. And it is portable where Peek is locked to one browser.
The best preview tool is the one that actually lets you work without opening tabs. Not just glance. Not just peek. Actually work.
