SQL Linter by SqlInt review
A free browser SQL linter with live diagnostics across seven dialects.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SQL Linter by SqlInt is a free, browser-based tool for reviewing queries as they are written. It is aimed at developers, analysts, and SQL learners who want immediate feedback on anti-patterns, ambiguous references, style issues, and risky constructs without creating an account. The tool covers Standard SQL (ANSI), PostgreSQL, MySQL, SQLite, BigQuery, Snowflake, and SQL Server (T-SQL), making it suitable for common SQL environments and multi-dialect work.
Its main strength is the depth of its live diagnostics. Results identify severity, rule code, explanation, and line-column position, while clickable findings jump to the relevant location in the query. Rules detect issues such as SELECT * usage, implicit comma joins, missing WHERE clauses, and ambiguous references. Selected formatting, casing, and alias issues can also receive one-click fixes. Local browser processing means pasted SQL is analyzed without uploading it, which fits quick reviews of queries that should remain in the browser.
The Free plan costs 0, requires no signup, and has no usage limits. Because the product is delivered through the web, it works well as a focused, low-friction review utility rather than as a connected development workflow. It is a good choice for individual SQL review, learning, and fast pre-commit checks performed manually in a browser. Teams seeking editor integration, CI automation, integrations, or custom rules should choose a SQL linting tool built around those workflow requirements instead.
