Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Mako is an open-source template library for Python teams that want application templates to use Python expressions and control structures. It compiles templates into Python modules and can process text such as HTML, XML, and email content. Its logic-based syntax will suit developers who want template logic close to Python; teams seeking templates without embedded code may prefer a more restricted syntax model.

The feature set centers on composition and reuse. Templates can inherit from other templates through blocks and inheritance chains, define reusable blocks, and include other templates while passing arguments. Expressions support configurable filters, including HTML, XML, and URL escaping, and filtering can be configured across a template. The built-in default filter stringifies expressions, so HTML escaping is not automatic by default; teams rendering HTML need to account for that behavior in their filtering choices. Template and lookup caching are also supported.

Mako is MIT-licensed, open source, and listed for Linux, macOS, and Windows, with self-hosted deployment. It has no AI features. The published product information describes an open-source model and a free plan, rather than paid tiers. That makes it a fit for teams comfortable managing a Python library in their own environment, from solo projects through enterprise use. Choose Mako when Python-based template logic, inheritance, and reusable definitions are priorities; consider an alternative if automatic HTML escaping or a syntax that separates presentation from Python logic is a requirement.

Mako pros and cons

  • Where it wins
    • Compiles templates into Python modules.
    • Supports Python expressions, control structures, and reusable definitions.
    • Provides inheritance, includes, configurable filters, and caching.
  • Where it doesn't
    • HTML escaping is available but is not applied automatically by default.
    • Templates can contain Python logic, which may not suit teams seeking a restricted syntax.
    • Self-hosted deployment puts operation within the team's environment.
