It provides a command-line interface and programmatic API to generate, version, and apply database schema changes. The tool detects model changes, generates migration files with timestamped versions, and can upgrade or downgrade the database schema. It also includes an inspectdb command to reverse-engineer existing database tables into TortoiseORM model definitions.\n\nThe package depends on tortoise-orm (the ORM it targets), dictdiffer (for comparing model states), asyncclick (for CLI), and anyio (for async compatibility). It's actively maintained and supports modern Python versions (3.10 through 3.14). However, the project's own documentation warns that tortoise-orm>=1.0.0 includes built-in migration support as an alternative, so users should verify whether Aerich or the built-in solution better fits their needs.","worth_installing":"Yes, if you are using TortoiseORM and need structured database migrations. The package is actively maintained, has no known vulnerabilities, and low install friction. However, check whether tortoise-orm>=1.0.0's built-in migration support meets your needs first, as the project itself recommends it as an alternative for newer versions."},"id":"aerich","links":{"html":"https://skillfed.io/packages/aerich","md":"https://skillfed.io/packages/aerich.md","pypi":"https://pypi.org/project/aerich/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-05","license_spdx":null,"license_treatment":"permissive","name":"aerich","python_support":"supports_current","summary":"A database migrations tool for Tortoise ORM."},"popularity":{"monthly_downloads":274337,"position":8192,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.10.0"}
