Cosmos DB Explorer

Read your Azure Cosmos DB documents without leaving the editor.

Pick a database, pick a container, press Run. That's it.

Columns come from the fields your documents actually have. Select a row to read the whole document. The request charge in RU is shown for every query.

Why this one

The usual way to look at a Cosmos document is the Data Explorer in the Azure portal: another browser tab, another sign-in, and a scroll through system fields before you reach your own data. The usual alternative is a toolkit that reaches out to every subscription the moment the editor starts.

• Nothing happens until you press Connect. No network call is made at startup, so it cannot slow your editor down or throttle your account.
• No third-party libraries at all. It speaks the Cosmos DB REST API directly using the Node runtime that ships with VS Code. Nothing to conflict with, and nothing extra to load.
• Read-only by design. It reads databases, containers and documents. It never writes, never deletes, and never changes throughput.

What it does

• Browse databases and containers in the sidebar
• Run a Cosmos DB NoSQL query and read the results as a table
• Columns are built from the fields your documents actually have, not a fixed list
• _rid, _self, _etag, _attachments and _ts are hidden by default, and one setting brings them back
• Select a row to read the whole document as indented JSON
• Results arrive one page at a time, so a large container does not freeze the editor
• The request charge in RU is shown for every query, because that is what it costs you
• Works against the local Cosmos DB emulator as well as a real account

Trial and price

Every feature is open for 14 days. No card is needed, and nothing is charged automatically. The trial is a date on your own machine. This extension never asks for payment details and never could charge you.

After 14 days, browsing stays free:

A licence is USD 3 a month, or 30 a year, the same as the JetBrains edition of this tool.

Get a licence — no account to create, no card stored with us. The key goes in with Cosmos DB: Enter Licence Key.

If the licence check cannot reach our server, the extension stays unlocked. Being offline is not a reason to stop someone who paid.

Your key

The account key is kept in the editor's own secret storage, never in a project file that could reach version control. A read-only key is enough. The extension talks to Cosmos DB directly from your machine, and nothing is uploaded anywhere.
