Heya, it's Shiichan! Today I've got news that makes local development on Cloudflare Workers so much nicer. So exciting!

Cloudflare Changelog developers.cloudflare.com

What was announced?

Over on the Cloudflare Changelog, meet "Local Explorer". It's a tool that lets you peek at and edit the data your local Workers have stored, straight from a browser interface and a REST API.

The story so far

Until now, when you wanted to know what data lived locally, you had to write throwaway scripts or dig through .wrangler/state by hand. A bit of a chore, right?

What changes

Start a local development session and press e in your terminal, or open /cdn-cgi/explorer on your local dev server. From there you can view and edit your data, and it works even when multiple Workers are running at once.

Dive Deep

It supports five resource types:

  • KV — browse keys, view values and metadata, and create, update, and delete key-value pairs.
  • R2 — list objects, view metadata, upload files, and delete objects, with directory views and multi-select.
  • D1 — browse tables and rows, run arbitrary SQL, and edit schemas in a full data studio.
  • Durable Objects (SQLite storage) — browse each object's SQLite tables, run SQL, and edit schemas.
  • Workflows — list instances, view status and step history, trigger new runs, and pause, resume, restart, or terminate instances.

There's also a REST API at /cdn-cgi/explorer/api, and hitting the root endpoint returns an OpenAPI specification. Just point an AI coding agent at it and it can work with your local resources with no manual setup. That means an agent can populate test data in KV or D1, inspect Durable Object state, or trigger Workflow runs as part of an iterative loop.

It's available in Wrangler 4.82.1+ and the Cloudflare Vite plugin 1.32.0+. For more, check the Local Explorer documentation.

Wrap-up

  • Local Explorer is a browser UI and REST API for viewing and editing your local resource data.
  • It supports five types: KV, R2, D1, Durable Objects, and Workflows.
  • Launch it with the e key or /cdn-cgi/explorer; needs Wrangler 4.82.1+ / Vite plugin 1.32.0+.
  • The REST API ships with an OpenAPI spec, so it fits nicely into AI-agent development loops.
  • Perfect for anyone building Workers while poking at their data locally!
