Yes, if you need lightweight command-line template rendering and don't mind a dormant project. The package is stable, has low install friction, no vulnerabilities, and a small dependency footprint. GPLv3 licensing is a consideration if you're building proprietary tools. The lack of recent maintenance is not a blocker for simple use cases, but don't expect bug fixes or new features.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with a pure Python wheel.
- The package is dormant (last release 2021-12-25, last commit 2023-11-13) but has no known vulnerabilities and depends on stable, widely-used libraries.

What it is and what it does
jinja-cli is a thin command-line wrapper around Jinja2 that lets you render templates without writing Python code. You provide a template file (or stdin), data in one of several formats (JSON, YAML, XML, INI), and the tool outputs the rendered result to stdout or a file. Data can come from a file, environment variables, command-line key-value pairs, or regex-matched environment variables, with clear precedence rules for how sources are merged.
It's useful for scripting, build pipelines, and configuration generation where you want template rendering without a full application framework. The tool is small and straightforward—it depends on Jinja2, PyYAML, xmltodict, and argparse-ext. It has not been actively maintained since late 2021, though the codebase is stable and has no known security issues.
Use it for
- Generate configuration files from templates and environment variables in CI/CD pipelines
- Render HTML or text templates with data from JSON or YAML files in shell scripts
- Populate template-based code generators or scaffolding tools from command-line arguments
- Transform XML or INI data into formatted output using Jinja2 syntax
- Build static site generators or documentation tools that need template rendering without a framework
