The Cemetech website also hosts tools for calculator programmers, including the SourceCoder TI-BASIC IDE and the jsTIfied TI-83+/84+ emulator.

Major software projects have included networking libraries for calculators and other low-resource devices, as well as the hardware and computer software to support internet-connected calculators, an extensive shell called Doors CS for these devices, and work on distributed computing and image processing projects by the founder and several staff members.

In November 2012, Cemetech became one of the primary news sources introducing TI's new TI-84 Plus C Silver Edition and Casio's fx-CP400 graphing calculators.

[29][30] In early 2011, Cemetech's members took a vocal stand against Texas Instruments' educational division for the TI-Nspire CX graphing calculator to be introduced in Spring 2011, calling on community members to "ignore the Nspire CX and get a [...] Prizm" from TI competitor Casio.

[31] While much of the hobbyist community agreed with the letter or spirit of the proclamation, a discussion between teachers and community members on a semi-official TI-Nspire discussion group prompted criticism of Cemetech's attitude as contrary to the purpose of TI's calculators, exemplified in "[o]ne thing that [...] is NOT wrong is TI's refusal to make the NSpire a platform for Doom or Quake or any other distraction that kids enjoy.
