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
- An active internet connection.
How to Use
Open a .tex
file in VS Code.
Press Cmd + K
(Mac) or Ctrl + K
(Windows/Linux).
This opens the login page for KeplerTeX.
Once logged in, your LaTeX document will compile automatically and the first PDF preview will appear.
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.
Features
- Zero local setup – start compiling without installing TeXLive or other LaTeX distributions.
- Seamless workflow – edit, compile, and preview without leaving VS Code.
- Fast PDF rendering – preview your LaTeX output in seconds.
Usage Limits and Plans
- Free Tier: Each user has a limit of 150 compilations per day.
- Pro Tier (coming soon): For heavy users, a paid plan will increase daily compilation limits (for example, up to 500 per day) and may include additional benefits such as faster queue priority.
These limits help us manage infrastructure costs while keeping KeplerTeX accessible to everyone.
