KeplerTeX

KeplerTeX lets you compile LaTeX documents directly inside VS Code — no local TeX installation required. Simply log in, write your LaTeX code, and compile instantly.

Requirement

• vscode version : ^1.100.0

How to Use

1. Open a .tex file in VS Code.

2. Press Cmd + K (Mac) or Ctrl + K (Windows/Linux).
   This opens the login page for KeplerTeX.

3. Once logged in, your LaTeX document will compile automatically and the first PDF preview will appear.

4. After the initial login and compile, use:

   • Cmd + S (Mac) or Ctrl + S (Windows/Linux)
     to trigger subsequent compiles and update the preview.
   • Cmd + K (Mac) or Ctrl + K (Windows/Linux)
     to pause the compiler. Press again to unpause and resume compiling.

Tip: Keep your .tex file open while editing. Each save updates the preview without additional setup.

Try It Out – Hello World Example

Create a file named hello.tex and paste the following code:

\documentclass{article}
\usepackage{amsmath}

\begin{document}
Hello, World!  

This is your first document compiled with KeplerTeX.  

Here is a simple equation:

\[
E = mc^2
\]

\end{document}

Log in with KeplerTeX (Cmd + K)(Mac)/(Ctrl + K)(Windows/Linux)

Save your (Cmd + S)(Mac)/(Ctrl + S)(Windows/Linux) .tex file. Your first PDF will render instantly.

Usage Limits and Plans

• Free Tier: Each user has a limit of 1000 compilations per day.
