Maintainer activity

50 people did triage or write work on this repository in the last 12 months.

Counts unlabeled, assigned, unassigned, milestoned, demilestoned, locked, unlocked over the last 12 months. These are issue and pull request events that require triage or write permission. Commits and code review are not counted. labeled and renamed are excluded because GitHub issue forms record the issue author as the actor. Figures from October 18, 2026. This count is not comparable across projects: each project's automation decides which of these events a person emits. How this is counted.

How this project is maintained

About 4% of issues opened in the past year have never received a reply. 97% of open issues come from outside the core team, so the backlog reflects real-world use rather than internal planning. Work labelled "package:wrangler" is answered fastest, typically in under an hour, while "pages" waits about 11 months. 24% of tracked open issues have had no activity in three months. 69% of issues opened in the past year have been closed, leaving a working backlog.

Detailed Description

The cloudflare/workers-sdk repository is the home of Wrangler, a command-line interface tool for developing, testing, and deploying Cloudflare Workers serverless applications. Written primarily in TypeScript, this monorepo contains multiple interconnected packages that together form a comprehensive development toolkit for building and managing edge computing applications on Cloudflare's global network.

The repository's core package, wrangler, serves as the primary CLI for building Cloudflare Workers. Beyond wrangler, the SDK includes create-cloudflare (C3), a CLI tool for scaffolding and deploying new applications to Cloudflare's platform. The miniflare package provides a local simulator for developing and testing Workers code before deployment, powered by workerd. Additional packages include chrome-devtools-patches, which is Cloudflare's fork of Chrome DevTools for inspecting both local and remote Workers, and pages-shared, an internal package containing shared code between Wrangler and Cloudflare Pages.

The repository's scope extends across multiple technology domains including serverless computing, edge computing, cloud platform infrastructure, JavaScript and TypeScript development, deployment automation, developer tooling, API integration, web development, and runtime environments. This breadth reflects the comprehensive nature of the SDK, which must support developers across various use cases and skill levels.

The SDK supports beta releases generated automatically on every commit to the main branch through the pkg.pr.new tool, allowing developers to test unreleased features and fixes without waiting for stable npm releases. The repository maintains active community engagement through Discord, GitHub discussions, and a public project board, with clear contribution guidelines documented in the CONTRIBUTING.md file. The official documentation is hosted at developers.cloudflare.com/workers, providing comprehensive guides on getting started, understanding how Workers operates, using the Wrangler CLI, observability features, and platform capabilities.
