How Katana compares

The dimensions below summarise where Katana sits versus the 3 alternatives on each axis that typically drives a switch decision.

Pricing posture: Every listed alternative is at Katana's price tier or above. Switching for cost alone won't help.
Open source coverage: Katana is commercial, every listed alternative is open source. Migration trades convenience for control.
Free entry tier: Every alternative offers a free or freemium tier. Each is testable without procurement.
JS rendering: Katana renders JavaScript; 2 alternatives skip it. The non-rendering options trade compatibility for cost and latency.
Structured output: Katana ships structured output; 3 alternatives do not. Migration means owning the parsing layer.
Self-hosting: Katana self-hosts and so does every alternative. Pick on ecosystem fit, not deployment model.
