A free, MIT-licensed Rust CLI for comparing database schemas. It supports PostgreSQL, MySQL/MariaDB and SQLite, plus SQL schema files. Inspect schema drift, export structured output and use a nonzero exit code in CI when schemas differ. dbdiff generates migration SQL with locking warnings for review; it does not execute migrations. The demo compares two synthetic SQL files.
A free, MIT-licensed Rust TUI for macOS and Linux. Find port conflicts, inspect the owning process and follow process-to-port-to-endpoint topology. Filter live connections or export JSON, CSV and NDJSON. Version 0.6.0 installs with Cargo or Homebrew. Process visibility depends on OS permissions; macOS uses lsof and Linux reads /proc.
A free, MIT-licensed canvas library for OHLCV charts. The TypeScript core supports candlesticks, lines, indicators and drawing tools, with React and Vue adapters. Try the hosted playground with generated candles and an SMA overlay. Your application supplies market data and transport; this is not an exchange feed.
