Stop breaking changes
before they ship
BreakGuard analyzes your code changes to show what will break, where it breaks, and how to fix it — before commit.
Built for modern development workflows

The ProblemBreaking changes happen in the dark
Most teams discover breaking changes too late—after the PR is merged, the pipeline fails, or production breaks.
Compiler errors don't show full impact
You fix the immediate error, but hidden dependencies break silently downstream.
CI feedback is late and expensive
Waiting 20+ minutes for a failed pipeline wastes time and context switching kills flow.
AI-generated changes increase breakage
Copilot and AI tools don't understand your codebase's dependency graph.
Everything you need for safer releases
BreakGuard integrates seamlessly into your editor, giving you instant feedback on the impact of every change.
Detects breaking API changes
Automatically identifies changes to functions, types, and exports that could break downstream code.
Traces real downstream usage
Maps actual usage across your entire workspace, not just direct imports.
Surfaces impacted files
See exactly which files and components will be affected before you commit.
Run only affected tests
Identifies which tests cover impacted code and runs them using your existing test runner—Jest, Vitest, or any other.
How BreakGuard works
Watch how BreakGuard catches a breaking change, traces its impact, and runs only the affected tests.
