wrangler-ui

Prisma Studio for Cloudflare Workers — run npx wrangler-ui in any Workers project to inspect and manage KV, D1, R2, and Worker metadata through a local web UI.

Installation

npm install -g wrangler-ui
# or run without installing
npx wrangler-ui

Authentication

wrangler-ui needs a Cloudflare API token to read and write KV, D1, R2, and Worker data. It looks for credentials in this order:

1. CLOUDFLARE_API_TOKEN environment variable.
2. api_token or oauth_token in ~/.wrangler/config/default.toml (written by wrangler login).
3. CLOUDFLARE_API_KEY + CLOUDFLARE_EMAIL environment variables.

If wrangler login does not provide a token the SDK accepts, create an API token at https://dash.cloudflare.com/profile/api-tokens with at least Cloudflare Workers:Read and the resources you want to manage, then run:

set CLOUDFLARE_API_TOKEN=your_token_here
wrangler-ui

Usage

In a project with a wrangler.toml, wrangler.json, or wrangler.jsonc:

# Start the UI on an available port
wrangler-ui

# Specify port and environment
wrangler-ui --port 3000 --env staging

# Do not open the browser automatically
wrangler-ui --no-open

# Point to a different project directory
wrangler-ui --cwd ./apps/my-worker

The tool reads your Cloudflare API token from CLOUDFLARE_API_TOKEN or from ~/.wrangler/config/default.toml.

Features
