The Spec Kit community builds extensions, presets, bundles, walkthroughs, and companion projects that expand what you can do with Spec-Driven Development. All community contributions are independently created and maintained by their respective authors.
Note
Review community source code before installation and use it at your own discretion. A catalog listing is not an audit or endorsement.
Extensions add new capabilities to Spec Kit — domain-specific commands, external tool integrations, quality gates, and more. Over 130 community extensions are available from 70+ authors, covering everything from accessibility governance to multi-agent orchestration.
Presets customize how Spec Kit behaves — overriding templates, commands, and terminology without changing any tooling. Community presets range from language localizations to entirely different development methodologies.
Bundles compose extensions, presets, workflows, and steps into role or team stacks that can be installed together.
Workflow step types add reusable executable behavior that workflows can select
