Mustache templating language renderer
Decision gist · record as of 2026-08-14
Yes, if you need a lightweight, spec-compliant Mustache renderer with no dependencies and your project does not require active maintenance. The package is stable and well-tested, but it is abandoned—no updates since 2021. Choose it for simple templating tasks where you control the template syntax and do not expect future feature requests or bug fixes. For active development or complex templating needs, consider a maintained alternative.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Installation is straightforward with no runtime dependencies.
- However, the project is abandoned—last release was 2021-01-02 and no commits since 2023-08-24.
- While the codebase is stable and spec-compliant, expect no maintenance or bug fixes going forward.

What it is and what it does
Chevron is a Python implementation of the Mustache templating language, a logic-less template syntax that separates presentation from data. It takes a template string (or file) containing Mustache syntax and a data dictionary, then renders the template by substituting variables, iterating over lists, and invoking partials and lambda functions.
The package is designed to be spec-compliant with the official Mustache specification and offers both a Python API and a command-line interface. It supports partials (template includes) loaded from dictionaries or the filesystem, custom delimiters, and lambda functions for conditional or computed template logic. With no runtime dependencies, it installs cleanly and runs as a pure Python module.
Use it for
- Generate HTML emails or documents from templates and dynamic data in web applications.
- Render configuration files or code templates from data structures in build or deployment scripts.
- Build command-line tools that produce formatted output using Mustache templates and JSON data.
- Create reusable template libraries with partials for consistent document or UI generation.
- Implement simple report or invoice generation by combining template files with structured data.
