6 ranked · nothing here paid to be listed

  1. 1

    OrcaSlicer

    Free and open source, and the most actively developed slicer of 2026.

  2. 2

    PrusaSlicer

    Free and open source. Slower to change, harder to break.

  3. 3

    Cura

    Free and open source, with the widest printer support of any of them.

  4. 4

    Bambu Studio

    Free, but only worth running if you own the hardware it was written for.

  5. 5

    Kiri:Moto

    Free and browser based. Nothing to install and nothing to license.

  6. 6

    Chitubox

    Free tier is enough to start in resin. The support tools you will eventually want are not in it.
