Ellipsis Review 2026

Automated AI code review and bug-fixing bot that comments on pull requests, answers code questions, and generates working, tested fixes — grounded in your codebase.

Ellipsis is a GitHub-native AI engineer that lives in your pull requests. When a developer opens a PR, Ellipsis runs an automated review: it flags bugs, security issues, missing tests, and style violations inline, and — unlike most review bots — it can also push commits to fix the issues itself, generate unit tests, and answer reviewer questions in the PR comment thread. It indexes your repository so reviews are grounded in actual project context (your existing patterns, your types, your test conventions) rather than generic best practices, which dramatically reduces false positives compared to first-generation lint-style AI reviewers. Teams configure Ellipsis with a YAML file (`ellipsis.yaml`) that specifies which checks to run, which paths to ignore, and custom rules unique to the codebase. Beyond review, Ellipsis can be summoned with @-mentions to draft an entire PR from a Linear ticket or issue, similar to a junior engineer. It is sold per-developer with a free tier for open-source repos and Pro / Enterprise plans for private repos with SSO, audit logs, and self-hosted options.
