Calixo Calculators — VS Code Extension

A quick calculation without alt-tabbing to a browser — run Calixo: Open Calculator and every calculator opens in a panel right next to your code. Runs entirely inside VS Code; nothing is sent to a server.

Download the extension (.vsix)

Install it

Not on the VS Code Marketplace yet, so installing takes one extra step via a local .vsix file — this is a standard, first-class way to install any VS Code extension:

  1. Download the .vsix file (don't unzip it — VS Code opens it directly).
  2. Open VS Code, go to the Extensions view (Ctrl+Shift+X / Cmd+Shift+X).
  3. Click the … menu at the top of the Extensions view → Install from VSIX…
  4. Select the downloaded file.
  5. Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P) and run Calixo: Open Calculator.

What data does it use?

None of your input ever leaves your editor. The extension bundles the same calculation engine that runs calixo.cloud, so every result computes locally and instantly, with no network request and no account.

FAQ

Is a .vsix file safe to install?

Yes — "Install from VSIX" is a built-in VS Code feature for exactly this. It's the same install mechanism VS Code uses internally once an extension passes Marketplace review; this one just skips that queue for now.

Will it stay up to date?

Re-download and reinstall the .vsix whenever a new calculator is added. A Marketplace listing (with automatic updates) is planned.

Does it work in Cursor or other VS Code forks?

Yes — any VS Code-compatible editor that supports "Install from VSIX" works the same way.
