–Costs rise quickly as contact lists grow

–Full potential requires clean, well-structured customer data

–Large feature surface has a learning curve for small teams

Solarch

Draw the architecture; Solarch writes the code that matches it

Live node/edge canvas

Model the whole backend — controllers, services, repositories, tables, DTOs and queues — on one surface with 16 semantic edge types across 8 families.

Default-deny rules engine

An illegal connection such as wiring a controller straight to a table is rejected the instant you draw it, based on 7 anti-patterns and 3 conditional checks.

Hybrid code engine

Stage one compiles the graph deterministically into skeletons with zero tokens; stage two uses surgical AI to fill only the empty function bodies.

GraphRAG grounding

A LangGraph-powered architect grounds every plan in a vector-indexed library of canonical patterns instead of autocompleting from scratch.

Strengths & Pros

+Architecture is validated before any code is written, so drift is structurally prevented
+Deterministic stage-one generation keeps token costs low
+Writes commit only when the graph passes the rules, not just when the model feels confident
+Same diff engine across editor, CLI and AI agent

Limitations

–Requires willingness to model the system as a graph before coding
–Deterministic generation is currently deepest for NestJS-style backends
–The full codebase tier is a serious monthly commitment for individuals
