QueryPilot
Akhilesh Vangala
Self-hosted natural-language-to-SQL copilot over a lens-manufacturing PostgreSQL star schema, with a FastAPI backend and React UI. It returns generated SQL, applies read-only guardrails, and includes a small execution-result golden evaluation.
Verified 2026-09-03. Repository was created the same day and had 0 stars/0 forks and no tagged releases. Guardrail source restricts execution to one SELECT/WITH statement, blocks DDL/DML and reads of application tables, and caps broad queries at 500 rows. The built-in golden set contains 12 cases including a required DROP refusal; README claims 12/12 with its deterministic StubLLM, not an externally benchmarked LLM result. Demo credentials and default JWT secret are explicitly local-only.
