Overview

BrowserGap runs pages in a remote browser and streams their rendered pixels to a browser interface on the user’s device. Because the page’s HTML, CSS, and JavaScript stay off that device, this model suits workflows that need remote execution rather than local page rendering. It is also designed for automation, security, privacy, and CBII use cases.

Teams can self-host from source or use a Docker image, with a hybrid deployment model. That flexibility is useful for builders fitting browser isolation into an existing stack, but it also places deployment responsibility on the operator. Docker deployment has no sound, and the binary prerequisites require Windows, Mac OS, or Linux with Google Chrome installed.

Key features

Interactive remote browsing

BrowserGap supports tabs, form input, file uploads and downloads, modal dialogs, incognito tabs, and touch or pointer scrolling. Users can clear cache, history, and session cookies, which helps when a workflow needs session data removed between tasks. Adaptive image resampling adjusts to available bandwidth to help preserve responsiveness and image quality.

The controls do not amount to a fully complete browser experience: text selection, page zoom, multi-touch, WebGL, and fluid use of multiple windows are unimplemented or buggy. Those gaps matter for teams whose users depend on precise page interaction or graphics-heavy applications.

Automation and embedding

Developers can embed a BrowserView in another web application, connect Puppeteer to the browser service, and use the VF.openSecurely(url) API method. Automation visibility allows a person to observe a job and intervene when it needs input. This makes BrowserGap particularly relevant to assisted workflows, where automation and human review need to share a browser session.

Document handling

Secure document viewing with content disarm and reconstruction is supported. In the source-available edition, operators must set up the document viewer themselves, so this capability is not a turnkey document-security service.

Pricing

BrowserGap uses a freemium model. The Source-available community edition costs 0.00 USD per free under AGPL-3.0 and a custom exemption. Governments, researchers, journalists, and nonprofits may use it without purchase under stated in-house deployment conditions. This is the clearest fit for eligible organizations able to operate the software themselves; the license conditions should be considered before wider or commercial deployment.

The Managed session plan costs 3.81 USD per once for a session. Pro / license exemption has custom pricing, with flexible licenses, maintenance, deployment, delivery, and custom development options available by contacting the maker. Business inquiries go to Cris Stringfellow at cris@dosycorp.com.

Platforms

BrowserGap lists API, Linux, macOS, self-hosted, web, and Windows support. Its deployment prerequisites specify Windows, Mac OS, or Linux and an installed Google Chrome browser. The project is dual-licensed under AGPL-3.0 and a custom exemption, with commercial licensing available by contacting the maker.

Who it's for

BrowserGap is a good fit for developers and teams that want to embed isolated browsing, connect Puppeteer, or let people supervise automation jobs. It is also worth considering for eligible government, research, journalism, and nonprofit users who can meet the in-house deployment conditions. Teams seeking a hands-off managed service, or users who need the currently unimplemented browser interactions, should look elsewhere.

Pros and cons

Pros

Pixel streaming keeps page HTML, CSS, and JavaScript off the user’s device, fitting remote-isolation workflows.
Embedding, Puppeteer connectivity, and human intervention hooks connect browsing to application and automation flows.
Self-hosting and a free community edition give eligible operators deployment control without an upfront license charge.

Cons

Text selection, zoom, multi-touch, WebGL, and fluid multiple-window support are unimplemented or buggy, restricting some browsing tasks.
Operators must supply Google Chrome and manage deployment; the source-available document viewer also requires setup.
The one-time managed-session price does not establish session duration or other usage limits.

Alternatives

Browse browser isolation software to compare tools across the category. Kasm Workspaces is a freemium alternative with a free Community plan capped at five concurrent sessions and no commercial use; its Starter named-user plan is an option for buyers considering a paid named-user license.

Netskope One Private Access is a paid enterprise product with a free trial, suited to buyers evaluating an enterprise access offering rather than BrowserGap’s open-source deployment model. Authentic8 Silo is a paid option with a 30-day individual trial, limited egress nodes, and up to 10 Nexus AI prompts per day during the trial.

BrowserBox is a paid alternative whose evaluation license costs 20.00 USD per once per seat for 7 days and supports 1–10 concurrent sessions. Cisco Secure Access is a paid subscription with a free trial and tiered pricing based on covered-user count and subscription term.

Netzilo Enterprise Browser offers a free plan for up to five users and 100 devices, with community support only, and may suit teams whose requirements fit those caps. DefensX Remote Browser Isolation is a paid alternative with a free trial and plans that distinguish 30-day from 90-day log retention. Menlo Security Secure Cloud Browser uses custom quotes based on products and users.

Verdict

Choose BrowserGap if you need remote-rendered browsing that can be embedded in an application or paired with visible, human-supervised automation, and your team can handle deployment and license review. Look elsewhere if complete browser interactions, a self-contained document viewer, or a more turnkey service is central to the decision.
