Lesli Ecosystem
Lesli is designed to be modular. It uses standard Ruby on Rails engines (we call them modules) to extend and customize functionality, making it easy to build powerful, tailored applications on top of the Lesli framework.
The Lesli team maintains several production-ready engines, most of which are open source. These modules cover a wide range of common use cases and can be seamlessly integrated into your application to accelerate development.
Collections
A Collection is a group of modules organized by category or business industry. Collections help you quickly identify modules relevant to specific areas of your SaaS application.
Available Collections:
- Administration
- Sales & Marketing
- Productivity & Teamwork
- Finance
- Analytics
- Intelligence
- IT & Help Desk
- Security & Privacy
- Integrations
