asyncpg-trek
A simple migrations system for asyncpg
Decision gist · record as of 2026-08-14
Yes, if you use asyncpg and prefer raw SQL migrations without the overhead of SQLAlchemy/Alembic. The low install friction, permissive license, and straightforward API make it a reasonable choice for projects that fit its design. However, the Alpha status and lack of updates since July 2024 mean you should verify that it handles your specific migration patterns and be prepared to maintain it yourself if issues arise.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later and an existing asyncpg connection to a PostgreSQL database.
- Low install friction with a single runtime dependency (typing_extensions).
- The package is in Alpha status and has not been updated since July 2024, though the repository remains active.

What it is and what it does
asyncpg-trek is a lightweight migration tool for developers using asyncpg who want to write migrations as raw SQL or Python rather than adopting a heavier framework. It scans a folder you designate for migration files, tracks which ones have been applied to your database, and executes the necessary migrations to reach a target version—either upgrading, downgrading, or doing nothing if already at the target.
The library is API-centric rather than CLI-driven: you write the code that calls it, controlling how the database connection is created and when migrations run. This makes it straightforward to integrate into tests, Docker entrypoints, admin endpoints, or application startup routines. It requires Python 3.8 or later and depends only on typing_extensions at runtime.
Use it for
- Running migrations on application startup by specifying a hardcoded target revision for simple deployments.
- Wrapping migrations in a custom CLI or admin HTTP endpoint to manage schema changes in complex systems.
- Executing migrations in test fixtures to ensure a clean, versioned schema for each test run.
- Downgrading to a previous schema version when rolling back a deployment.
- Integrating migrations into a Docker image entrypoint for containerized applications.
