Forjet merges real, battle-tested GitHub repositories into production-ready projects using deterministic AST transformations. Not code generation — code composition. Describe your stack → Forjet discovers compatible repos → AST surgery merges them (renames imports, generates typed bridges, harmonizes APIs) → Firecracker sandbox validates it compiles and responds → download a ZIP that works with docker compose up. Same input, same output, every time. No hallucinations. Full provenance.
