Six disposable browsers compared in 2026

A one-off link arrives in chat. You need the rendered page, but you do not want the visit attached to your everyday browser. Opening it locally turns a temporary job into browser state that can outlive the check.

A disposable browser answers with a separate session. It should start clean, run the real page, and make session destruction the default. The important question is not whether the product has a cloud dashboard. It is what survives close.

We start with Legba because it is our product. Read its profile with our interest in mind. The other five are real alternatives. We state each documented fit. This order is not a product ranking.

What counts as a disposable browser

Our category definition uses a strict test. A disposable browser creates a temporary, isolated session for one job. The browser starts without your everyday state. When you close it, that session does not return.

Temporary browser and temp browser signal one-job intent. The term guide separates temporary, burner, and throwaway uses. This comparison covers products for that job.

That definition covers several delivery models. A vendor can stream a remote browser into a web page. A team can host containerized browsers on its own infrastructure. An enterprise can run remote browser isolation inside an existing security deployment. The model matters less than the lifecycle.

We excluded anti-detect tools built around reusable profiles. Their central job is keeping separate identities available across visits. That can be useful, but persistence is the opposite of disposal. Our disposable browser versus anti-detect browser comparison handles that category decision directly.

We also excluded developer-only headless browser APIs. A headless endpoint can automate a page. This comparison requires an interactive browser surface. The product must support a person opening a link. It may also serve code or agents.

Disposable and temporary browser comparison

The six products solve different versions of one problem. This table shows those differences before each product profile. Vendor facts were checked against first-party pages on September 2, 2026. We did not run comparative product tests.

Legba: routing and off-device isolation

Shield opens a page in an isolated browser off your device. Each session starts for one job and ends when you close it.

• Shield: opens the page in an isolated browser off your device.
• Ghost: gives your browser a private route.
• Clear ending: Shield destroys the session when you close the tab.

Documented fit: people who want routing and isolation in one extension. $10 a month, or $100 a year.

Main tradeoff: Legba has no persistent profiles by design. Sessions do not survive close. If your work requires returning to the same saved identity, that limit is intentional and real.

Browserling: quick link checks

Browserling runs real browsers remotely. It streams them into the current web page. Its Live API also supports iframe embedding. The Browserling site provides the interactive entry point.

Its clearest advantage is immediacy. You can check a link in a browser without installing a local product. The free tier makes that useful when the job is brief and occasional.

• Real browsers: the session runs remotely rather than emulating a page.
• No installation: the browser streams into the current web page.
• Free sandbox: ten monthly sessions last three minutes each.
• Broader workflows: browser extensions and a Live API are published.

Documented fit: quick, one-off link checks without installation.

Main tradeoff: the free cybersecurity sandbox allows ten monthly sessions. Each session lasts three minutes. Extensions and the Live API need separate evaluation.

Kasm Workspaces: self-hosted infrastructure

Kasm Workspaces streams containerized browsers and desktops. It is self-hostable and open-core. That combination gives teams direct control over where their disposable browsing environment runs.

Kasm stands apart from the hosted options here. The browser is one workload within a broader container-streaming model. Teams can operate the environment on infrastructure they control instead of sending every session to a vendor-hosted service.

• Self-hostable: the team chooses and controls the infrastructure.
• Broader workspace model: browsers and desktops use the same container-streaming approach.
• Open-core: teams can evaluate the model without treating it as a closed service.

Documented fit: teams that want disposable browsing on infrastructure they operate.

Main tradeoff: you operate that infrastructure. The control Kasm provides comes with ownership of the deployment and its ongoing operation.

Cloudflare Browser Isolation: Zero Trust deployments

Cloudflare Browser Isolation runs remote browser isolation inside Cloudflare Zero Trust. It belongs to an enterprise access and security deployment, not a standalone personal browsing tool.

That positioning is its strength. A company already using Cloudflare Access or Gateway can evaluate browser isolation inside the environment it already operates. The buying decision stays attached to the wider Zero Trust deployment.

• Remote execution: browsing runs through Cloudflare Browser Isolation.
• Zero Trust placement: the product sits inside Cloudflare's enterprise security offering.
• Existing-stack fit: Access and Gateway teams have the clearest reason to consider it.

Documented fit: enterprises already using Cloudflare Access or Gateway. They can extend that deployment into browser isolation.

Main tradeoff: this is an enterprise Zero Trust deployment. It is not a personal disposable browser you pick up for occasional link checks.

Browser.lol: free casual sessions

Browser.lol provides free virtual browser sessions in the cloud. Its place here is simple. It offers a zero-cost casual check away from your regular browser.

That narrow promise is useful. Not every unknown link justifies a subscription, an enterprise rollout, or infrastructure work. Browser.lol gives occasional users a separate cloud session for the task.

• Free access: the public entry path is ad-supported.
• Cloud session: the virtual browser runs away from the user's regular session.
• Upgrade path: lifetime Premium costs $89.
• Team path: Business workspaces support unlimited members.
• API surface: public documentation and API v7 are linked.

Documented fit: casual checks with Premium, workspace, and API upgrade paths.

Main tradeoff: the free session quota is dynamic. Active sessions can last up to two hours. They time out after two idle minutes.

Tempbrowser: short temporary sessions

Tempbrowser calls itself a throwaway cloud browser. The vendor says each session runs on a temporary virtual computer. Its homepage says sessions auto-destroy after fifteen minutes.

That lifecycle matches this comparison's category definition. The vendor also documents manual session ending. It states that no persistent profile, cookie jar, or history survives destruction.

• Homepage claim: sessions auto-destroy after fifteen minutes.
• Manual ending: users can end a session sooner.
• Temporary state: the vendor documents no persistent profile or history.
• Published plans: Free allows three-minute sessions. Pro allows sixty-minute sessions.

Documented fit: short checks after confirming the current live limit.

Main tradeoff: the vendor pages conflict. The homepage says fifteen minutes. Pricing lists three minutes on Free. It lists sixty minutes on Pro. Verify the live limit before relying on it.

How we compared these browsers

This is a documentation-based category comparison. It is not a product trial. We examined the path from one-off work to a browser session. That session should not become tomorrow's browser state.

1. Real browser: the session should render and behave like an interactive browser, not a screenshot service or developer-only headless endpoint.
2. Session destruction: closing the session should end its lifecycle. Reusable profiles fall outside strict disposal use cases.
3. Setup path: direct use and managed deployments serve different jobs. Infrastructure control may justify added setup.
4. Job fit: compare direct use, team deployment, and infrastructure ownership.

We did not assume that every reader wants the same delivery model. Kasm's operational work is a tradeoff for a casual user and the point for a self-hosting team. Cloudflare's enterprise scope is excessive for one person and sensible inside an existing Zero Trust deployment.

Pricing moves faster than comparison pages. $10 a month, or $100 a year. Check every vendor's current page before buying.

Pick the session model that matches the job

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. Choose Shield when the page should run off your device.

Choose Browserling for a direct check without installation. Choose Kasm when your team wants to own the infrastructure. Choose Cloudflare Browser Isolation when Cloudflare Zero Trust already defines the deployment.

Choose Browser.lol when free access and upgrade paths matter. Consider Tempbrowser when its current live limits fit the job. Its public pages disagree, so verify first.

If your priority is a session that ends completely, review Legba pricing and start with the extension. Pick the model that matches the work. Then verify what close actually destroys.
