Celld
Cloudflare's Durable Objects give developers a stateful primitive that always runs in exactly one place, useful for building things like live collaborative documents or chat rooms without hand-rolling distributed locking. That primitive is normally only available by building on Cloudflare's own platform. celld provides the same programming model, self-hosted and distributed across infrastructure the operator controls, rather than tied to a single vendor's cloud.
As of August 2026 the repository has 2,910 stars and 16 open issues.
This is placed in Assess. It offers a useful, well-understood programming model, stateful objects with single-location execution, without vendor lock-in to Cloudflare specifically. There is no first-person production use yet, which is the gate for Trial.
