What is Octopus?

Octopus is an AI-powered code review tool that connects to GitHub, GitLab, and Bitbucket, indexes your codebase for deep context, and automatically reviews every pull request — posting findings as inline comments with severity levels.

How does the automated review work?

When a pull request is opened, Octopus fetches the diff, retrieves relevant context from your indexed codebase using vector search, and sends it to an LLM (Claude, OpenAI, or Google Gemini) for analysis. Findings are posted directly on the PR with severity ratings: Critical, Major, Minor, Suggestion, and Tip.

Which programming languages are supported?

Octopus is language-agnostic. It reviews any text-based code file — TypeScript, Python, Go, Rust, Java, C#, Ruby, PHP, Swift, Kotlin, and more. Since it uses LLMs for analysis, it understands the semantics and patterns of virtually any language.

Is my source code safe?

Yes. Your code is processed in-memory and never stored permanently. Only vector embeddings are persisted for search. You can also self-host Octopus on your own infrastructure so your code never leaves your servers.

Does Octopus replace human reviewers?

No. Octopus augments your team's review process. It catches bugs, security issues, and style inconsistencies so your human reviewers can focus on architecture, design decisions, and business logic.

Is Octopus free to use?

Yes. Octopus is source-available under a Modified MIT License and free to self-host. The cloud service includes free credits to get started, with a credit-based model for continued use. You can also bring your own API keys to use your existing AI provider billing.
