Why Atlas

Database Schemas as Code

Define database schemas in declarative code. Use HCL, SQL or any ORM or language.

Supports all popular ORMs, such as GORM, Sequelize, Django, SQLAlchemy, Hibernate, and more.

Test your schemas and migrations using the Atlas testing framework.

Automatic Migration Planning

Define the desired state of your schema, and let Atlas automatically plan the SQL migrations. Like Terraform, but for databases.

Standardize schema changes using policies, regardless of the database or the ORM used.

Works with existing migration tools like Flyway, Liquibase, or migrate.

Planning Quick start

Verify Migration Safety in CI

Prevent destructive and backward-incompatible changes, or migrations that might fail or lock the database before they reach production.

Automate and customize reviews and approvals using policies.

2 reports were found in analysis

Blocking column changes detected

Changing column "c1" from "smallint" to "integer" alters storage

size from 2 to 4 bytes and requires a rewrite of the table (PG301)

Concurrent index violations detected

Adding a PRIMARY KEY on "users" not concurrently acquires an

ACCESS EXCLUSIVE lock, blocking all access to the table (PG104)

Deploy to production with modern tooling

Atlas seamlessly integrates with modern deployment tools like Kubernetes and Terraform to make it easy to deploy your migrations to production as part of your existing CD process.
