Fortress

Tilion builds browser infrastructure for software agents. Its engine is a recompiled Chromium build that corrects the browser fingerprint in C++ rather than patching it from JavaScript, so automated sessions present as a coherent machine instead of an instrumented one. Each launch produces a different but internally consistent profile covering GPU, screen, fonts, time zone, canvas and audio, and the engine reproduces recorded human mouse motion and supports real Widevine DRM playback. It is built for developers running agents, crawlers and scrapers that need to reach pages ordinary automation cannot load. The vendor states the engine passes DataDome, Akamai, Cloudflare and the standard bot checks. Builds are published for Linux, Windows and macOS, and the project ships through Docker, pip and npm, with a server implementing the Model Context Protocol so an agent framework can drive it directly. The engine itself is open source, and the company is backed by Y Combinator. Pricing is published in two tiers. A Developer plan is free and includes the recompiled engine, the per launch fingerprint rotation, the human motion playback and DRM support, and the cross platform distributions. An Enterprise plan is $2,000 per month, billed monthly, and adds self hosting on the customer's own infrastructure, a signed production key for a fleet, and support through a shared Slack channel with a 24 hour response commitment. The site states that white glove setup and custom pricing are available through a booked call. Buyers should weigh the legal and contractual position of evading bot detection on sites they do not control, since the product is explicitly designed to defeat those controls.
