# denoland/celld

> Open-source daemon that runs Cloudflare Workers applications on your own machines: Workers, Durable Objects, KV, Queues, D1, R2, Workflows, Cron and static assets from your existing wrangler.json. State lives in your own S3-compatible bucket with no consensus service or serving control plane.

- Magnitude: 2.3 out of 10 — Cooling
- Stars: 6,048 total · +21 stars measured 2026-10-22, 00:41–11:30 UTC, ≈ 40 by evening
- Star trust: star growth looks organic

## Useful for

- Run an existing Workers project locally with celld dev without a cloud bucket
- Deploy a fleet of celld nodes on your own servers with state in an S3 bucket
- Move an app using Durable Objects and D1 off Cloudflare onto your own hosting

## Why it’s here

- Star-counter measurements on 2026-10-22 (UTC), 00:41–11:30: 6027 → 6048 stars (+21). This is the change over that interval.
- Estimated end-of-day forecast: about +40 stars, using observed gains and the previous day.
- Interest is fading: the two-day pace is 44% of the previous week and a half.
- Hacker News: “Deterministic Simulation Testing in Celld” — 37 points, 12 days ago.
- About 8 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 408
- Issues and pull requests: 165
- Watchers: 28
- Average over the last week: 54 per day
- Usual pace: 48 per day
- Latest release: v0.6.3 (2026-10-21)

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
