Your AI colleague that catches critical issues before they ship.

Bismuth works on Python and JavaScript (TypeScript) code bases. It periodically scans your code base and autonomously finds and fixes bugs. It also leaves review comments on pull requests when it finds critical bugs and then provides inline suggested fixes.

Our Benefits

Fix critical issues before they become a problem with an AI that understands your entire codebase

Catch issues before they're merged.

Bismuth can leave comments for critical issues with suggested fixes as they review your pull request.

Learn more

Works around the clock.

Bismuth periodically scans your code base for issues that are live in production. We then open pull requests that outline the issue and provide a fix.

Self-testing and verification

Every code change is tested against your existing test suite and build process. Bismuth verifies its own work before submitting changes.

Technical Capabilities

Bug fixing, quality, and security go hand in hand.

Bismuth acts as a second line of defense against bugs that can cause financial harm and reputational damage. We reduce the time your developers spend fixing bugs and let them keep their focus on features.

Bismuth goes beyond security critical bugs.

Bismuth not only detects bugs that effect scurity which can have direct financial implications, but also unintended logic bugs which could cause reputational harm and slow development.

Bismuth works on your entire codebase.

Bismuth analyzes your entire codebase when checking pull requests so we can detect issues surrounding changes not just the changes themselves.

You stay in control.

Review and approve all changes before they're committed. Bismuth creates clean, atomic commits as part of pull requests with detailed messages explaining what changed and why.

Integrated Into Common Workflows

Bismuth works directly on GitHub, it can review pull requests and open it's own just like any one on your team.

Reviews

Bismuth only steps in to comment on a review if there are clear logical or security concerns given the context of the work.

Scans

Bismuth is always checking your code base for new issues and will open pull requests to fix them when it finds them.

Communicates

Add Bismuth to slack and it will let you know it's found something you should take a look at.
