Do you know a product as pleasant to use as Netlify?

Vercel is similar. Somewhat better pricing, and if you use Next.js, there are "magic" features like image transformations or incremental static regeneration that are zero-conf on Vercel but require additional hacking to get working on other jamstack hosts, to varying degrees of success.

Next.js is technically open-source, but unfortunately a lot of more powerful features depend on Vercel (who owns it)... it's actually bad enough that I'm worried about vendor lock-in, and wish I had done more due diligence upfront. It's only getting worse too, with features like Next.js Live collaboration (think GDocs for websites) being built around Vercel infrastructure.

Gatsby is another competitor, though way too complicated (requiring a transformation step to GraphQL, I think) and pricy/slow. Github Pages for similar sites.

For the CMS part of a jamstack, I really like DatoCMS for its editor-friendly features & GraphCMS for its dev-friendly features. Both are better IMO than the industry leader, Contentful (which is insanely overpriced).

Outside of serverless hosts, I love Datadog's synthetic tests for simulating & testing user journeys across pages.

have you tried Supabase as the backend complement to Netlify?
