Agentic Index
Asteroid vs Twin (2026)
Both score 9.5 of 14 running agents through interfaces with no usable API, and they scale differently. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Twin is an autonomous AI employee planning, choosing tools and executing across 50,000 applications and websites plus a proprietary browser agent for portals, triggered by email, call, schedule or webhook, with approval gates on irreversible actions, proven at scale through Qonto's invoice operator for more than 500,000 small businesses. Asteroid is supervised computer use for regulated back offices, compiling its own deterministic scripts and discovering private APIs, graph based and self healing, HIPAA ready. Twin for breadth and proven volume; Asteroid for regulated work where every run must be inspectable.
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Asteroid and Twin 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 Asteroid if
- Regulated back office work is the context and live supervision is required.
- Deterministic scripts compiled from exploration is what makes this auditable.
- HIPAA readiness is a hard requirement.
Choose Twin if
- Breadth across 50,000 applications is what your workflows actually touch.
- A proven deployment at 500,000 small businesses is the scale evidence you want.
- Trigger flexibility across email, call, schedule and webhook fits how work arrives.
