Sound:  The primary difference between a keyboard and a piano is the sound they produce. A piano produces sound by striking strings with hammers, while a keyboard produces sound by electronic means.

Touch and feel:  A piano has weighted keys that are responsive to touch, providing a tactile feel that mimics that of a real acoustic piano. Keyboards, on the other hand, often have lightweight keys that lack the same level of responsiveness.

Maintenance:  Pianos require regular tuning and maintenance to keep them in optimal playing condition. Keyboards, on the other hand, require minimal maintenance and can often be repaired easily.

Cost:  Pianos are generally more expensive than keyboards due to their size, weight, and complexity. Keyboards are more affordable and accessible to a wider range of musicians.

Versatility:  Keyboards are more versatile than pianos in terms of the range of sounds and effects they can produce. Keyboards often include a range of presets and sound effects that can be easily customized to the musician's preference.

Portability:  Keyboards are more portable than pianos and can be easily transported to gigs or rehearsals. Pianos, on the other hand, are not as portable and require a dedicated space for storage and use.

Learning curve:  Pianos require more skill and training to play than keyboards, due to the weighted keys and the need for proper technique. Keyboards are generally easier to play and can be learned quickly.

Recording:  Keyboards often have built-in recording capabilities, allowing musicians to easily record and produce their music. Pianos, on the other hand, require external equipment for recording.

Aesthetics:  Pianos are often seen as a symbol of elegance and sophistication and can be a statement piece in a room. Keyboards are generally more functional than decorative and do not have the same aesthetic appeal as a grand piano.
