Durable Objects now has a Free tier, but it's only available for the SQLite backend and thus not yet available for Rust Workers: https://developers.cloudflare.com/changelog/2025-04-07-durable-objects-free-tier/

Actually, the SQLite-backed Durable Objects support the KV API, so I don't think this is a blocker for using the Free tier with the Rust bindings after all.
