Disclaimer: I work for Inngest (https://www.inngest.com), which works in the same area and released 2 years ago.
The restate API is extremely similar to ours, and because of the similarities both Restate and Inngest should work on Bun, Deno, or any runtime/cloud. We most definitely do, and have users in production on all TS runtimes in every cloud (GCP, Azure, AWS, Vercel, Netlify, Fly, Render, Railway, Cloudflare, etc).
