About
Ellipsis is an AI developer teammate designed to make software engineers more productive through automated code reviews, async code generation, and intelligent Q&A — all within GitHub. Installed in over 67,000 repositories, Ellipsis reviews every commit of every pull request, surfacing logical mistakes, anti-patterns, and style guide violations before they reach production. Beyond reviews, Ellipsis supports asynchronous code generation: tag it in a GitHub comment with a task, and it returns working, tested code in minutes. Teams can also use @ellipsis-dev to ask questions about their codebase directly in pull request comments. Its 'Style Guide-as-Code' feature lets teams write style rules in plain language, which Ellipsis then enforces automatically. Ellipsis learns from team feedback over time, customizing the type of review comments it surfaces to match each team's preferences. It also generates weekly changelogs summarizing what changed in a codebase and why. Security-conscious teams will appreciate its SOC 2 Type 1 certification, zero source code retention policy, and strict no-rogue-commit guarantee — it never commits code without explicit permission. Pricing is $20 per developer per month with unlimited usage, and the tool is completely free for public GitHub repositories. It supports all programming languages and installs in two clicks, making it accessible to startups and enterprises alike.
Key Features
- Automated Pull Request Reviews: Catches logical bugs, anti-patterns, and style guide violations on every commit of every pull request across all supported programming languages.
- Async Code Generation: Assign coding tasks to Ellipsis via GitHub comments and receive working, tested code back in minutes — no context switching required.
- Style Guide-as-Code: Define your team's style rules in natural language; Ellipsis enforces them automatically and flags violations on every review.
- In-Comment Q&A: Tag @ellipsis-dev in any GitHub comment to ask questions about the codebase, get explanations, or request clarifications instantly.
- Automated Changelogs: Generates weekly summaries of what changed across the codebase and why, reducing the manual burden of writing release notes.
Use Cases
- Automatically reviewing every pull request for logical errors, security issues, and style violations before human review.
- Assigning minor bug fixes or feature tasks to Ellipsis via GitHub comments to get working code without interrupting the team.
- Enforcing a team's custom style guide at scale across all repositories without manual enforcement overhead.
- Generating weekly changelogs and release notes to keep stakeholders informed about codebase changes.
- Reducing the need for synchronous code review cycles by using Ellipsis Q&A to answer questions directly in pull request threads.
Pros
- Installs in 2 Clicks: Seamlessly integrates with GitHub with minimal setup, making adoption fast and frictionless for any team.
- Security-First Architecture: SOC 2 Type 1 certified, zero source code retention, and a strict policy of never committing code without explicit developer approval.
- Learns from Feedback: Adapts review comment style over time based on team preferences, reducing noise and surfacing only the most relevant issues.
- Free for Public Repositories: Open-source maintainers and public project contributors get full access at no cost.
Cons
- GitHub-Only Integration: Currently limited to GitHub repositories, which excludes teams using GitLab, Bitbucket, or other version control platforms.
- Per-Seat Pricing Can Add Up: At $20 per developer per month, costs can scale quickly for larger engineering teams compared to flat-rate tools.
- AI Review Accuracy Varies: As with all AI tools, review quality depends on context; Ellipsis may occasionally surface false positives or miss nuanced issues.
Frequently Asked Questions
How does Ellipsis integrate with my codebase?
Ellipsis installs as a GitHub app in just two clicks. Once installed, it automatically reviews every commit on every pull request across all repositories you authorize.
Is Ellipsis free to use?
Yes — Ellipsis is completely free for public GitHub repositories. For private repositories, pricing is $20 per developer per month with a free 7-day trial.
Does Ellipsis store my source code?
No. Ellipsis does not persist your source code anywhere. It is only processed temporarily on private AWS VPC servers while a job is running, then discarded.
Can Ellipsis generate and commit code automatically?
Ellipsis can generate working, tested code when assigned a task via GitHub comments, but it will never commit code without your explicit permission. It raises a side-PR so changes are always visible and reviewable.
What programming languages does Ellipsis support?
Ellipsis supports all major programming languages, making it suitable for polyglot teams and projects with diverse tech stacks.
