PAGE FAQ
Common questions about SaaS
Can a SaaS company also use Hotline?
Absolutely. Expose input → output capabilities from your SaaS as Hotlines on the Marketplace — an additional agent channel without affecting the main product.
Does Hotline mean there is no UI at all?
No. Consoles still matter for discovery, approvals, operations, and operator workflows. The difference is that the callable capability is the primary product unit.
Why compare Hotline to SaaS?
Because many people try to map the concept to familiar software categories. The comparison clarifies that they serve different supplier populations and product shapes, and can coexist.
