What is bugstack?

bugstack is an automated code repair platform that catches runtime errors in production via a lightweight SDK, writes surgical fixes (max 3 files, 30 lines changed, no new dependencies), runs them through your existing CI pipeline, and opens tested pull requests on GitHub. The full cycle from error to PR takes under 2 minutes.

How It Works

bugstack follows a three-step process every time a runtime error occurs in production:

1. Detect — The bugstack SDK captures the error, stack trace, and surrounding context from your running application and sends it to the bugstack platform.
2. Fix — bugstack analyzes the error, reads the relevant source files from your repository, and writes a minimal, targeted fix that resolves the root cause.
3. Ship — The fix is committed to a new branch, your CI pipeline runs against it, and a pull request is opened on GitHub for your team to review and merge.

What bugstack Fixes

bugstack targets clear-cut runtime errors that have a single, unambiguous fix:

• Null/nil reference errors — TypeError, NoneType, NoMethodError nil:NilClass, nil pointer dereference
• Missing or incorrect imports — ImportError, ModuleNotFoundError, wrong relative paths
• Type mismatches — calling methods on wrong types, unexpected argument types
• Unhandled async failures — missing await, unhandled promise rejections
• Key/index access errors — KeyError, index out of range, undefined property access
• Framework-specific errors — hydration mismatches, ActiveRecord::RecordNotFound, route handler crashes

What bugstack Does NOT Fix

bugstack is intentionally scoped. It does not attempt to fix:

• Silent logic errors — bugs that produce wrong results without throwing an exception
• Architecture changes — refactors that require restructuring multiple modules or services
• Dependency management — upgrading libraries, resolving version conflicts, or adding new packages
• Database migrations — schema changes, data backfills, or migration conflicts
• Business logic requiring domain knowledge — rules that only a human with context about the product can define

Getting Started

Setting up bugstack takes about 30 seconds:

1. Connect GitHub — Authorize bugstack and select the repositories you want monitored.
2. Install the SDK — Add the bugstack SDK to your application (available for JavaScript, Python, Ruby, and Go).
3. Deploy — Push your updated code to production. bugstack starts monitoring immediately.
