cubic vs Ellipsis (2026)
cubic and Ellipsis are the young challengers in AI review, expanding in different directions. cubic invests in the reviewing human, with a desktop app, ordered diffs, and diagrams, plus nightly repository scans with automatic fix pull requests. Ellipsis invests in delegation, an assignable coding teammate and a YAML platform for governed background agents. Both are free for public repositories.
