Not this one though, they are open source so someone else would start to offer new hosted instances: https://github.com/neondatabase/neon

Some Helm charts: https://github.com/neondatabase/helm-charts

It could potentially be one of their partners:

Vercel https://neon.tech/docs/guides/vercel

Hasura https://neon.tech/docs/guides/hasura

Neon CEO. We are certainly not going to sunset Neon any time soon. We are extremely well funded and also growing super quickly. Expect some exciting announcements soon!

Neon at least has open-sourced their core offering, which provides a migration path for folks who make bigger bets on their platform. So yeah, there's every possibility they'll go away at some point, but unlike a lot of SaaS offerings, it's all Postgres over the wire and under the hood, so you have plenty of migration options (OSS, another managed Postgres vendor, Aurora, Cloud SQL, etc.)
