Legba vs SquareX: Disposable Browsers Compared
SquareX runs a cloud-rendered disposable browser. Legba runs browser-native isolation through a Chrome extension. This comparison breaks down architecture, pricing, session handling, and who each product is built for.
You have decided that disposable browsing is the right approach. You do not want persistent cookies tracking you across sessions. You do not want a phishing page running JavaScript on your real machine. You want to close the tab and have everything disappear. Good. That decision is the hard part.
Now comes the next question: which product? If you are evaluating disposable browser tools in 2026, two names keep surfacing: Legba and SquareX. Both promise session isolation. Both destroy browsing data on close. Both position themselves as answers to the browser-level threats that VPNs and antivirus tools were never designed to stop.
But the resemblance is mostly surface-level. Under the hood, these products use different architectures, different deployment models, and different philosophies about where isolation should happen. If you are choosing between them, the architecture difference is the decision that matters most.
This comparison covers what both products do, where they diverge, and who each one is best suited for. We built Legba, so we are biased. We will be honest about that and about where SquareX has advantages.
What Both Products Do
Before the differences, the common ground. Both Legba and SquareX provide:
- Disposable browsing sessions. Open a session, browse, close it. Cookies, cache, session tokens, and browsing history are destroyed.
- Protection from browser-borne threats. Phishing kits, malicious JavaScript, and drive-by downloads are contained in the disposable environment rather than executing on your real machine.
- Fingerprint isolation. Each session presents a clean browser fingerprint, making cross-session tracking significantly harder.
- Chrome compatibility. Both products work within or alongside the Chrome browser ecosystem.
If you just want "some form of disposable browsing," either product delivers that. The differences only matter when you care about how the isolation works, what the latency implications are, and what additional capabilities each platform offers.
Architecture Differences: Where the Products Diverge
SquareX: Cloud-Rendered Disposable Browser
SquareX runs a full disposable browser instance in the cloud. When you open a session, a Chromium-based virtual machine spins up on SquareX's infrastructure. The web page renders entirely on their servers, and your local browser receives a visual stream of the rendered output.
This is classic Remote Browser Isolation (RBI) architecture. The local device never touches the raw web content. The isolation boundary is the cloud VM itself.
The tradeoff: every interaction (scroll, click, keystroke) requires a round trip to the cloud. Latency depends on the distance between you and the nearest SquareX server and the current load on their infrastructure.
Legba: Browser-Native Edge Isolation
Legba takes a different approach. Instead of spinning up a separate browser in the cloud, Legba works as a Chrome extension that routes browsing sessions through isolated environments at the network edge. The isolation happens close to the user, leveraging edge computing infrastructure to minimize latency.
Because Legba operates as a native Chrome extension, users stay inside their existing browser. There is no context switch to a separate application or a remote desktop stream. The browsing experience feels like normal Chrome usage with the isolation layer running underneath.
The tradeoff: the isolation model depends on the extension's ability to intercept and route traffic rather than running a fully separate browser instance.
Side-by-Side Comparison
| Dimension | Legba | SquareX |
|---|---|---|
| Architecture | Browser-native Chrome extension with edge isolation | Cloud-rendered disposable Chromium VM |
| Deployment | Install Chrome extension. No separate app. | Browser extension that launches cloud sessions |
| User experience | Browsing inside existing Chrome. No context switch. | Browsing in a remote browser streamed to your tab |
| Session model | Ephemeral. Destroyed on tab close. | Ephemeral. Destroyed on tab close. |
| Latency profile | Low. Edge-based processing near user. | Variable. Depends on cloud VM distance and load. |
| Geographic exit points | 15+ countries | Multiple regions (varies by plan) |
| Isolation state indicator | Ghost Mode (visible on/off state) | Session indicator in extension UI |
| MSP and team management | Yes. Multi-tenant MSP platform available. | Team plans available. No dedicated MSP tier. |
| AI agent sandbox | Yes. OpenClaw sandbox for isolated AI agent execution. | No dedicated AI agent sandbox. |
| Pricing | $10/month (individual) | Free tier available. Paid plans vary. |
| Primary target user | Individuals and small teams wanting instant isolation | Privacy-conscious users wanting a separate disposable browser |
Where SquareX Has an Edge
We built Legba, so we will be straightforward about where the competitor does well.
- Truly separate browser instance. Because SquareX runs a full Chromium VM in the cloud, the isolation boundary is as strong as it gets. The disposable browser is a completely separate process on separate infrastructure. There is no shared memory space with your local browser at all.
- File handling in isolation. Files downloaded in a SquareX session can be scanned or inspected within the cloud environment before they reach your local device. The full VM model makes this more straightforward.
- Free tier availability. SquareX offers a free tier that lets users test disposable browsing before committing to a paid plan. Legba does not offer a free tier.
- Established in the disposable browser category. SquareX has been positioning itself in this space and has built awareness among privacy-focused users who specifically want a cloud-rendered disposable browser experience.
Where Legba Has an Edge
- No context switching. Legba runs inside your existing Chrome browser. You do not open a separate application or interact with a streamed remote desktop. The browsing experience is native Chrome with isolation running underneath. For users who live in Chrome all day, this matters.
- Edge-based latency.Because isolation happens at the network edge rather than in a centralized cloud VM, Legba's latency profile is generally lower. Scrolling, clicking, and typing feel responsive because the processing is geographically close to the user.
- Ghost Mode. A clear, visible indicator that shows whether isolation is active or inactive. Users always know their session state without checking a settings panel.
- Simple pricing. $10 per month. No tiers to compare, no feature gating. The full product at a flat price.
- MSP platform. For managed service providers, Legba offers a multi-tenant dashboard for managing browser isolation across multiple client organizations. SquareX does not offer a dedicated MSP management layer.
- OpenClaw sandbox. Legba includes a sandboxed environment for running autonomous AI coding agents (like OpenClaw) in full isolation. This is a distinct product surface that SquareX does not offer.
- 15+ country exit points. Geographic routing is built into the product, which means you can shift your browsing location without needing a separate VPN or proxy.
Who Should Pick Which
Choose SquareX if:
- You want a fully separate cloud browser instance with the strongest possible isolation boundary
- You want to try disposable browsing for free before paying
- You are comfortable with the latency tradeoff of cloud-rendered browsing
- You do not need MSP management, AI agent sandboxing, or geographic exit point flexibility
Choose Legba if:
- You want isolation inside your existing Chrome workflow with no context switching
- Latency matters and you want edge-based processing close to your location
- You need geographic exit points built into the isolation product
- You manage security for multiple clients and need an MSP dashboard
- You run AI agents and want isolated sandbox environments for them
- You prefer simple, flat pricing with no feature tiers
Neither product is universally better. The right choice depends on your workflow, your latency tolerance, and which additional features matter for your use case.
The Bigger Picture
Legba and SquareX are two products in a rapidly expanding market. The remote browser isolation sector is growing at over 30% annually, and more Chrome-compatible isolation products are entering the space every quarter.
