How Seltz compares

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

Pricing posture: Every listed alternative is at Seltz's price tier or above. Switching for cost alone won't help.
Open source coverage: Seltz and all listed alternatives are commercial hosted services. Self-hosting requires moving to the open-source frameworks category.
Free entry tier: Every alternative offers a free or freemium tier. Each is testable without procurement.
JS rendering: Seltz and the alternatives all skip JavaScript rendering. None will work on JS-heavy SPAs without pairing with a headless browser.
Structured output: Seltz and every alternative emit structured output. The differences are schema flexibility and post-processing cost.
Self-hosting: Neither Seltz nor any alternative self-hosts. All run as managed services with their own data paths.
