How it got here
2013 · Ecto API expansion and tooling
This period focused on expanding Ecto's capabilities with support for window functions, a new query API, and advanced ordering options. The team also introduced dedicated Mix tasks and generators for database management and repository scaffolding, while significantly increasing test coverage for core components and tasks.

2014–2015 · Ecto modularization and test expansion
This period focused on refactoring Ecto's internal architecture by splitting large modules like Ecto.Adapter and Ecto.Query.Builder into specialized, modular components. The team simultaneously expanded test coverage across query building, repository operations, and association handling to ensure the new structure was robust and correct.

2016–2023 · Ecto API and example modernization
This period focused on modernizing the Ecto codebase by introducing dedicated modules for schema loading and metadata management, replacing ad-hoc structures with robust, typed structs. Concurrently, the Friends example application was refactored to align with current Elixir and Ecto best practices, while new reference guides were added to document associations and CRUD operations.

elixir-ecto/ecto was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point the surveyor at a repository you know and see whether you agree with it.
About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 5 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit 6c0c457be6 — the exact code this score is about.
- Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
