Most SQL tools treat SQLite as a “flavor” of a generic SQL parser. They approximate the language, which means they break on SQLite-exclusive features like virtual tables, miss syntax like UPSERT, and ignore the 22 compile-time flags that change the syntax SQLite accepts. So I built syntaqlite: an open-source parser, formatter, validator, and LSP built directly on SQLite’s own Lemon-generated grammar. It sees SQL exactly how SQLite sees it, no matter which version of SQLite you’re using or which feature flags you compiled with. It ships as a CLI, VS Code extension, Claude Code LSP plugin, and C/Rust libraries. There’s also a web playground which you can try now: paste any SQLite SQL and see parsing, formatting, and validation live in the browser, no install needed. Full documentation is available here. Here’s syntaqlite in action: Formatting with the CLI > syntaqlite fmt -e "select u.name,u.email,count(e.id) as events from users u join events e on e.user_id=u.id where u.signed_up_at>=date('now','-30 days') group by u.name,u.email having count(e.id)>10 order by events desc" SELECT u.name, u.email, count(e.id) AS events FROM users AS u JOIN events AS e ON e.user_id = u.id WHERE u.signed_up_at >= date('now', '-30 days') GROUP BY u.name, u.email HAVING count(e.id) > 10 ORDER BY events DESC; Validation with the CLI
