Agentic Index
Fellou vs Opera Neon (2026)
Two agentic browsers, one from a startup and one from an established browser vendor, close on coverage at 9 and 8.5 of 14. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Fellou's Deep Action engine plans multi step web and desktop tasks, shows you the editable plan before executing, runs in a sandboxed shadow workspace and remembers context through Agentic Memory, on 160 million dollars raised at a 530 million valuation. Opera Neon executes cross page tasks with real time visibility and takeover controls, builds apps and reports in offline cloud virtual machines and runs sourced research, model agnostic at a published 19.90 dollars a month. The editable plan before execution is Fellou's strongest idea; the published price is Opera's.
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Fellou and Opera Neon are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 969 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
Choose Fellou if
- Seeing and editing the plan before the agent runs is the control you want.
- Desktop tasks alongside web tasks are in scope.
- A sandboxed shadow workspace is what makes you comfortable letting it run.
Choose Opera Neon if
- A published price at 19.90 a month means no sales conversation and no surprises.
- Buying from an established browser vendor lowers the risk on something you use all day.
- Model agnostic matters because you do not want the browser choosing your model.
