	<!--
	NOTE: The sections below are reserved for more deployment platforms not listed above.
	Feel free to submit a PR that adds a new section with a link to your platform's
	deployment guide, as long as it meets these criteria:
	1. Users should be able to deploy their site for free.
	2. Free tier offerings should host the site indefinitely and are not time-bound.
	Offering a limited number of computation resource or site counts in exchange is fine.
	3. The linked guides should not contain any malicious content.
	The Vite team may change the criteria and audit the current list from time to time.
	If a section is removed, we will ping the original PR authors before doing so.
	-->

The new links need to meet the criteria described above. That said, based on my understanding of the document, I don’t think it meets the criteria. The free tier offering appears to be time-limited.
