Legba vs SquareX after the Zscaler acquisition
SquareX is now part of Zscaler. Compare that current path with Legba's independent Chrome extension, two browser modes, and published price.
The market changed. Zscaler acquired SquareX in February 2026. Its public Chrome Web Store listing is no longer available. That means this is not a current choice between two independent self-serve extensions.
Legba is the product we build. We are biased. This comparison keeps that bias visible and avoids assigning current features or prices to SquareX that its new owner has not published.
The short answer
| Question | Legba | SquareX |
|---|---|---|
| Current status | Independent Chrome extension | Acquired by Zscaler |
| Buyer path | Chrome Web Store | Review current Zscaler products |
| Published price | $10 a month, or $100 a year. | No current self-serve price verified here |
| Browser job | Ghost routes. Shield isolates. | Use current Zscaler documentation |
| Agent path | Ready skill for browser routing and isolation | No current claim made here |
What Legba currently does
Legba is a Chrome extension with two modes. Ghost gives you a private browser route. Shield opens a page in an isolated browser off your device.
Ghost changes the browser route. It does not isolate page execution. Shield opens the page in an isolated browser off your device. Its session is destroyed when the tab closes.
Agent builders can call the same routing and isolation through a ready skill. That skill covers the browser step. It does not host the whole agent or isolate every connected tool.
What not to infer
- Closing a session does not revoke data already submitted to a site.
- A private route does not make signed-in activity anonymous.
- Browser isolation does not replace endpoint, identity, or download controls.
- This page does not claim an independently benchmarked latency advantage.
- Historical SquareX features may not describe Zscaler's current offer.
Which path should you choose?
Choose Legba when you want the currently published Chrome extension, its two clear modes, and a direct self-serve price. Choose the Zscaler path when your decision is already part of a broader Zscaler evaluation. Confirm capabilities and commercial terms with current Zscaler material.
