VulpineOS Launch

VulpineOS is an operator system for browser agents.

It is built for stealth-aware, hardened, self-hostable AI browser agents that need to survive the real web.

The stack is based on Firefox / Camoufox and is open-source under MPL 2.0.

The core idea is simple: browsers were built for humans, not agents.

When agents use the web, they run into problems that normal browser automation was not designed to handle:

- Prompt injection from hidden DOM

- Pages changing between reading and acting

- Token waste from huge accessibility trees

- Detection from weak or inconsistent browser fingerprints

VulpineOS gives teams the infrastructure to run browser agents that can:

- Hold consistent browser identities

- Warm trust before target workflows

- Rotate through BYO proxy pools

- Geo-sync fingerprint, timezone, locale, and WebRTC IP

- Run in fleets from your own infrastructure

- Operate through a web panel or SSH-friendly TUI

- Connect to 30+ LLM providers

- Use 36 MCP browser tools

- Self-host with Docker / Vulpine-Box

- Work with budgets, approvals, webhooks, and auditability

Some current runtime numbers:

- 93.1% smaller DOM snapshots vs compact Chrome AX tree

- 74.6% smaller than Playwright ariaSnapshot

- 39.9M input tokens avoided per 1,000 snapshots

- Around ~200 active agents on a 32GB / 16-core workstation

- 36 MCP tools

- 30+ LLM providers

- Built on Camoufox 146.0.1 / Firefox 146

We are opening private operator access for teams building with browser agents.

VulpineOS is especially relevant for:

- Agent builders

- Data teams

- Infra owners
