rTeX

Deployed example here

Minimal LaTeX rendering server.

Requirements:

• Python 3.5.2
• The libraries in requirements.txt
• An installation of LaTeX, of some description.
  • MikTeX and TeXLive both work decently.
• A command called convert. I think it's part of imagemagik but I'm not sure.

Security Concerns

The following settings should be applied to your texmf.cnf file in order to prevent security breaches:

shell_escape = f
parse_first_line = f
openout_any = p
openin_any = p
