Sequoia seed.
SquareX raised its seed round from Sequoia to build a disposable browser. The pitch: cloud-rendered Chromium VMs for anyone who wanted a throwaway session.
For SquareX refugeesIndependent
SquareX is gone.Legba is still here.
The public SquareX Chrome Web Store listing is no longer available. On February 5, 2026, Zscaler announced the acquisition. If you installed a Chrome extension because you did not want to start with an enterprise platform, you do not have to now. Legba is still a Chrome extension. Still independent. Still $10 a month.
- Patented isolation
- $10 a month, flat

What happened
to SquareX.
We will keep this factual. SquareX users liked SquareX. The honest summary is more useful than any pitch.
Series A.
A Series A round brought institutional capital in and expanded SquareX's browser-security ambitions beyond the earliest consumer pitch.
Chrome listing pulled.
The public SquareX Chrome Web Store URL now resolves to an empty listing state. Whatever the exact removal date was, the self-serve install path is no longer live.
Zscaler acquisition.
Zscaler announced and closed the acquisition. Its public messaging focused on securing standard browsers with lightweight extensions rather than separate third-party browsers.

Three steps.
No data to export.
SquareX sessions were ephemeral by design, so there is nothing to export. That is actually the point. Migration is just install and toggle.
Uninstall SquareX.
If the old extension is still pinned, right click the icon and pick Remove from Chrome. If it is already gone from your extension list, skip this step. Chrome has already cleaned it up for you.
Install Legba.
Open the Chrome Web Store listing. Click Add to Chrome. Accept the extension permissions. The whole thing takes about twenty seconds on a normal connection.
Flip Ghost Mode on.
Click the Legba icon in the toolbar. Toggle Ghost Mode to on. You are now browsing through an isolated edge session. Close the tab, the session is destroyed. Open a new one, you get a fresh container.

What you keep. What you gain.
Keep — what does not change
- Your Chrome workflow. No separate app, no remote desktop stream.
- Disposable sessions that destroy themselves on tab close.
- Phishing, drive-by malware, and malicious script containment.
- A visible indicator of session state, so you always know if isolation is active.
- Per-session fingerprint isolation to frustrate cross-session tracking.
Gain — what gets better
- Edge-based latency that feels like normal Chrome browsing, not streamed video.
- AI prompt data protection built into the isolated session, not bolted on.
- A dedicated MSP tier with multi-tenant dashboards, bulk provisioning, and per-client policy.
- OpenClaw sandbox for running autonomous AI coding agents in full isolation.
- Geographic exit points in 15 plus countries without a separate VPN.
- An independent company roadmap that is not driven by enterprise platform integration.
Questions
SquareX users ask.
No. Legba and SquareX are separate products from separate companies, with different architectures. Both run as Chrome extensions and both offer disposable, isolated browsing sessions. The difference is that SquareX rendered a full browser VM in the cloud and streamed pixels back to your tab, while Legba isolates at the network edge and keeps the browsing experience native to Chrome. Legba is also an independent company, so the product is not bundled into an enterprise platform.
