Modular open sources the Mojo language entirely under Apache 2.0
DynamicWebPaige · x · 2026-08-19
At the ModCon keynote, Modular announced that Mojo is now fully open source under Apache 2.0 (with LLVM exceptions). The Mojo compiler, tooling, and everything needed to build the language are now on their GitHub repo.
Key context:
- Mojo is a next-gen general-purpose language targeting GPUs, AI accelerators, and advanced compute, integrating recent compiler research.
- It had been developed with an open community but a closed compiler for four years; Mojo hit 1.0 (source stability) just last week.
- The open-sourcing was deliberate and staged: standard library first, then hundreds of thousands of lines of kernel code and tools, now the compiler.
- The team argues small tight-knit design teams (not committees) find a language's "soul," while broad community feedback avoids echo chambers.
Apache 2.0 plus LLVM exceptions allow freely building and distributing Mojo-compiled binaries.
