What is it

Bismuth is an AI-powered agent designed to optimize software development workflows by scanning your codebase, reviewing changes, and delivering regression-tested pull requests (PRs). It focuses on turning tickets and issues into high-quality PRs that pass tests, fuzzing, and static analysis, helping teams ship more features while preventing bugs and security issues. Bismuth integrates with popular tools and supports custom extensions via its SDK, enabling tailored workflows for Go, Python, and JavaScript/TypeScript projects.

Features

    • Ensures changes are regression- and security-tested.

  • Smart Review Workflow

    • Reviews comments only on material issues where logic or security risks exist.
    • Reduces review fatigue by filtering out non-critical noise.

  • Integrated Tooling

    • Works with GitHub, Bitbucket, and GitLab for version control.
    • Connects with Jira, GitHub Issues, and Linear for issue tracking.

  • SDK and Custom Integrations

    • Extend Bismuth to fit unique workflows with a robust SDK.
    • Build custom integrations, automate complex processes, and embed Bismuth’s intelligence directly.
