Nguyen Anh Quynh announced the Keystone Engine Project, with an IndieGogo funding campaign to help them:
We are very excited to announce our IndieGogo campaign for Keystone Engine, the next-gen assembler framework! After Capstone & Unicorn, Keystone is the latest of our on-going effort to bring better tools to the reverse-engineering community. Now with the final missing piece Keystone, we complete the magical trilogy of disassembler – emulator – assembler. Come support us, and help to spread the news, so together we can solve the lingering problem of missing the assembler framework once, and for all! The Keystone name came from some private conversation with Felix “FX” Lindner. Thanks for such a great inspiration, FX!
