What are the main differences between Agile and Scrum?

Agile is a philosophy and a set of values for software development, while Scrum is one of the frameworks (methodologies) for implementing Agile.

Characteristic	Agile	Scrum
Type	Philosophy / Methodology	Framework / Methodology
Flexibility	High	High
Iterativity	Yes	Yes (Sprints)
Values	Individuals and interactions are more important than processes and tools; working product is more important than comprehensive documentation; customer collaboration is more important than contractual negotiations; readiness to change is more important than following the initial plan.	Transparency, Inspection, Adaptation.
Roles	Does not prescribe specific roles	Product Owner, Scrum Master, Development Team.
Events	Does not prescribe specific events	Daily Scrum, Sprint Planning, Sprint Review, Sprint Retrospective.
Artifacts	Does not prescribe specific artifacts	Product Backlog, Sprint Backlog, Increment.
Application	Can be implemented with different frameworks (Scrum, Kanban, XP, etc.)	A specific way of applying Agile, with clear rules and roles.

In simple words: Agile is a general "how we should work," and Scrum is a specific "recipe" or structure for how to do it.
