Up to 10 × 10. Exact rational arithmetic; very large fractions switch to decimals. No eigenvalues. Everything is calculated in your browser; nothing you type is uploaded.
All operations use exact fractions on big integers, so inverses and determinants have no rounding error. RREF uses Gauss–Jordan elimination and reports the rank and pivot columns.
The determinant of [[2, 1, 0], [1, 3, 1], [0, 1, 4]] is 18 and its inverse starts with 11/18, −2/9, 1/18.
