Static code analysis tool for T-SQL scripts and SSDT projects

PostgreSQL migration linter. Blocks unsafe migrations before merge: 112 rules, the real Postgres parser, lock analysis, auto-fix. CLI, GitHub Action, MCP.

SQL Server / T-SQL migration linter: validates and explains DDL before it runs — locking (Sch-M), table rewrite vs metadata-only, reversibility, idempotency, failure risk. Deterministic static analysis, offline, CI-ready with SARIF and a GitHub Action. No LLM.

MCP server and CLI for sqlike: deterministic SQL analysis and query-equivalence checking. Tokenizes locally, so your real table names and values never leave your machine.

T-SQL static code analysis lib

A tool for linting/fixing SQL code within Python strings using SQLFluff

Integrate sql-lint in github action to check .sql file.

Local SQL analyzer for CLI and GitHub Actions with deterministic rules, annotations and PostgreSQL EXPLAIN tools.

Visual configurator for SQLFluff Configure SQL linting rules through a clean GUI. Dialect, indentation, layout and hundreds of rules — see the result live.

A SQL Linter in D Programming Language

126× faster sqlglot in C++. Parses, transpiles and optimises 40+ SQL dialects. Supports stored procedures. Python bindings available.

SQL Query Auditor & Optimizer -- analyze SQL for performance, security, and best practices

CI gate for analytical SQL: captures DuckDB execution plans and runtime distributions for a whole query corpus, then fails the pull request when a query regresses and names the operator that changed. Rank test anchored to a measured noise floor, plus a sqlglot anti-pattern linter and Snowflake transpilation.

Production-safe SQL query analyzer for Go — detects slow queries, N+1, and dangerous SQL patterns at runtime and in CI. Like golangci-lint, but for SQL.
