ViewFinder review
A self-hosted, pixel-only isolation option for teams building browser security into their stack.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ViewFinder is a clientless remote browser-isolation product from Dosyago. It runs a virtualized browser inside a web browser and sends rendered pixels to the endpoint, rather than executing the remote page’s HTML, CSS, or JavaScript there. Its self-hosted deployment model suits open-source teams that want to run isolation on local machines, cloud infrastructure, or servers while retaining control over the browser environment. The web interface works across Windows, macOS, and Linux, and supports secure browsing, form input, multiple tabs, incognito tabs, browser history navigation, and file transfers.
Its strongest fit is for teams that need an embeddable remote browser rather than only a standalone browsing experience. BrowserView and a managed API support browser embedding and opening links in secure remote browser contexts. Docker deployment, Puppeteer connectivity, and Chrome DevTools Protocol integration also give engineering teams several ways to connect ViewFinder to an existing application or automation workflow. File upload and download support extends the product beyond page viewing, while the clientless interface avoids requiring a separate browser client at the endpoint.
ViewFinder is narrower than browser-isolation products that combine remote rendering with security operations controls. The published positioning does not include verified malware scanning, data loss prevention, or session recording, so teams requiring those capabilities should choose a product that provides them. It is a strong candidate for open-source development teams, internal tools, embedded secure browsing, and self-hosted deployments. Organizations seeking a fully managed service or a broader security control set should evaluate other options alongside ViewFinder.
