Cloudflare D1 Plugin for Tabularis

A Tabularis plugin that lets you browse and manage your Cloudflare D1 databases directly from the app.

Built in Rust. Communicates with the Cloudflare D1 REST API.

---

Features

• Browse all D1 databases in your Cloudflare account
• View tables, columns, indexes, foreign keys, and views
• Run SQL queries with pagination
• Insert, update, and delete rows
• Create and drop tables and indexes
• Create, alter, and drop views
• ER diagram support

Installation

Option A — Pre-built binary

Download the latest release ZIP for your platform from the Releases page, extract it, and place the folder in your Tabularis plugins directory:

OS	Path
Windows	%APPDATA%\debba\tabularis\data\plugins\
macOS	~/Library/Application Support/debba/tabularis/data/plugins/
Linux	~/.local/share/debba/tabularis/data/plugins/

Note: The path includes debba\tabularis\data — not just tabularis. This is how Tabularis resolves its data directory on all platforms.

The result should look like:

plugins/
└── cloudflare-d1/
    ├── manifest.json
    └── cloudflare-d1-plugin   (or .exe on Windows)

Restart Tabularis and the Cloudflare D1 driver will appear in the connection picker.

Option B — Build from source

Prerequisites: Rust (stable). On Windows, the build embeds the plugin icon into the .exe via winres, which requires rc.exe from the Windows SDK (already present if you have Visual Studio Build Tools installed).

git clone https://github.com/josejorge/tabularis_cloudflare_d1_plugin
cd tabularis_cloudflare_d1_plugin
cargo build --release

Copy target/release/cloudflare-d1-plugin[.exe] and manifest.json into a cloudflare-d1/ folder inside the plugins directory above.

Setup

When creating a new connection in Tabularis, select Cloudflare D1 and fill in:

Field	Value
Host	(leave blank)
Port	(leave blank)
Username	Your Cloudflare Account ID
Password	Your Cloudflare API Token
Database	The name of your D1 database

Getting your credentials

Account ID — Log in to the Cloudflare dashboard, open any domain or the main account page, and copy the Account ID from the right sidebar.

API Token — Go to My Profile → API Tokens → Create Token. Use the Edit Cloudflare Workers template or create a custom token with D1: Edit permission.

You can create one connection per D1 database, all sharing the same Account ID and token.

---

Limitations

• No ALTER COLUMN — SQLite does not support modifying existing columns. Recreate the table instead.
• No DROP FOREIGN KEY — Foreign keys are defined at CREATE TABLE time and cannot be dropped individually.
• No schemas — D1 uses a flat single-schema model.
• No stored procedures — D1/SQLite does not support them.

---

Releasing

Pushing a v* tag triggers .github/workflows/release.yml, which builds the win-x64 and linux-x64 binaries and attaches the packaged zips to a GitHub Release automatically.

Registry

This plugin is listed on Tabularium via the .tabularium manifest at the repo root. That file is separate from manifest.json: manifest.json ships inside the release zip and is read by Tabularis at runtime, while .tabularium lives in the repo and is read by the registry to list, validate, and surface the plugin.
