JetBrains MPS

It uses projectional editing which allows users to overcome the limits of language parsers, and build DSL editors, such as ones with tables and diagrams.

MPS also provides many IDE services automatically: editor, code completion, find usages, etc.

[10] In April 2010, the Realaxy ActionScript Editor beta was released, the first commercial IDE based on the MPS platform.

GDF consists of domain-specific languages allowing for stepwise refinement of application definitions, from higher levels of abstraction towards implementation code to be run on a gamification engine.

[12] According to GDF's case study from Jetbrains,[13] MPS was chosen for three main reasons: the need to provide text-based DSLs, the availability of language extension mechanisms conveying consistency management between abstraction layers, and the provision of generators to automatically derive implementation code.
