Cloudflare Durable Objects client for wrangler dev

Planche is a free GUI for the SQLite storage of Cloudflare Durable Objects running locally in wrangler dev. Each object is a separate SQLite database, so it appears as a separate database in the tree. This is local development only. Deployed Durable Objects are not supported.

Features

Named objects appear as <namespaceId>/<object>, such as do-probe-Counter/probe-one; objects from newUniqueId() use their 64-character hex id
One profile sees the wrangler development registry, including objects from other wrangler dev sessions running at the same time
SQLite-aware editor and sqlite_master/PRAGMA schema tree for tables, views, triggers, columns and indexes
Editable grid for single-table SELECTs, CREATE TABLE DDL and an ERD built from foreign keys
Shows _cf_KV, where ctx.storage.put() data lives, while hiding miniflare’s internal __miniflare_do_name table
Requests auto-commit; BEGIN, COMMIT and ROLLBACK are unavailable

How it connects

Run npx planche and wrangler dev on the same machine, choose Cloudflare DO (wrangler dev), and enter the dev server URL (default http://localhost:8787). There is no account id, API token, password or SSH setup. Planche reads <devUrl>/cdn-cgi/local/explorer/api; no Worker-side component is installed or deployed.

Only loopback URLs are accepted, because allowing other hosts would turn the local agent into an HTTP proxy to arbitrary destinations.

Deployed objects cannot be queried through a documented Cloudflare SQL API. The dashboard’s Data Studio (Beta) uses an undocumented endpoint, and the only token permission that unlocks it is Workers Scripts Edit, which can deploy and modify every Worker in the account. Planche does not request that access. For deployed objects, use Data Studio or expose your own Worker endpoint.

Also available: SQLite viewer, MySQL client, MariaDB client, PostgreSQL client, SQL Server client, Oracle client, Neon client, Supabase client, Cloudflare D1 client, Redis client, Elasticsearch client and OpenSearch client.

Free to use

Planche has a free tier that needs no account and uploads none of your data — connection profiles live only in your browser. A few advanced features need Pro; see pricing.
