MarsX

Open-source dev platform uniting AI, no-code, code and micro-apps

About MarsX

MarsX is a development platform that combines AI assistance, no-code building, traditional coding, and reusable full-stack micro-apps in one workspace. Teams assemble products from pre-built modules that bundle interface, backend logic, database schemas, and admin panels for features like authentication, payments, and chat, then drop into a JavaScript IDE when custom logic is needed. The core Mars engine is open source under Apache 2.0, and finished applications can be exported and self-hosted without vendor lock-in.
