Browser / computer-use agentindependentVerified 2026-07-22

Agentic browser whose Deep Action engine plans multi step web and desktop tasks, shows the editable plan before executing, runs in a sandboxed shadow workspace, and remembers context via Agentic Memory; $160M raised at $530M valuation.

Fellou is an agentic browser whose Deep Action engine independently plans and executes complex web and desktop tasks across multiple apps: it generates a step by step action plan before acting, lets users review, edit, and approve each step, and allows live intervention mid run, with a Spark usage preview before every Deep Action for cost aware decisions. Tasks run in a sandboxed shadow workspace in parallel while the user keeps browsing, including deep parallel searches across public and logged in platforms. Agentic Memory connects browser history, chat history, page context, and a personal knowledge base for proactive personalized help, and users can create and share special purpose agents built in natural language on the open source Eko 2.0 framework. Fellou claims 80 percent completion on the Online-Mind2Web benchmark (vendor reported; the independent study's best agent scored 61.3 percent). An August 2025 security analysis documented a prompt injection vulnerability where malicious page content could hijack the agent. Freemium with premium tiers; $160M raised at a $530M valuation.

What is public

The freemium structure and Spark credit mechanics with per task cost previews are public; specific premium tier rates were not captured in retrieved materials.

Variable cost rationale

Subscription plus per task Spark credits means cost scales with agentic task volume, though the pre execution cost preview is the lane's most transparent variable cost control.

Overage / add-ons

Agentic tasks consume Spark credits; each Deep Action shows a Spark usage preview before execution for cost aware decisions.
