StepZen (acquired by IBM) auto-generates GraphQL APIs from REST endpoints, databases, and other sources. Declarative approach to API composition.
Reviewer scorecard
“The best open-source alternative to Claude Code. Model-agnostic, configurable, and the git integration is solid. Perfect if you want control over your tools.”
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“Free, open-source, and surprisingly capable. The trade-off vs Cursor/Claude Code is polish — it works but requires more setup and CLI comfort.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“Aider proves that AI coding doesn't need to be locked into a proprietary IDE. The model-agnostic approach means it gets better as every LLM improves.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
