MergeGuard
Policy-Driven PR Automation for GitHub

Turn Pull Request EnforcementInto a Smart Policy Engine

MergeGuard extends GitHub's native capabilities with conditional enforcement, dynamic approval rules, and context-aware required checks—reducing CI cost and keeping teams aligned without leaving GitHub.

Trusted by engineering teams worldwide

How It Works

MergeGuard transforms static branch protection into a flexible, repository-defined policy system

1

Define Policy Rules

Configure review and merge policies in a simple YAML file. Set conditional requirements based on paths changed, lines of code, PR labels, authors, or even semver levels for dependency updates. MergeGuard acts as a deterministic decision layer on top of GitHub.

  • Context-aware required checks
  • Conditional approval logic (AND, OR)
  • Path-based rule matching

2

Automatic Policy Evaluation

When a PR is opened or updated, MergeGuard evaluates your policies against the PR context—what changed, who changed it, and why. It determines exactly which checks and approvals are required, skipping unnecessary CI runs to reduce costs and noise.

  • Skip expensive tests for docs-only changes
  • Auto-approve patch-level Dependabot updates
  • Enforce stricter rules for critical paths
3

Merge Readiness & Enforcement

MergeGuard posts a dynamic checklist comment showing exactly what's needed for merge. GitHub Check Runs block merges until all policy conditions are met, preserving GitHub's native merge guarantees while adding intelligent context awareness.

  • Real-time status updates on PR changes
  • PR dependency management (stacked PRs)
  • Deterministic, auditable decisions
Merge Validation

Powerful Features

Everything you need to streamline code reviews and maintain high quality standards

Enforce Review Policies
Require reviewers based on custom rules—LOC changed, file paths, labels, authors, or semver levels for Dependabot. Support AND-logic for code owners requiring all listed reviewers to approve.
Merge Readiness Validation
Dynamic PR comments summarizing what's needed for merge. GitHub Check Runs block merges until conditions are met. Re-evaluates on updates, commits, or manual triggers.
Dependabot Auto-Approval
Optionally approve or auto-merge patch-level dependency updates from Dependabot. Fully configurable by update type, scope, or content to maintain security while reducing review overhead.
Context-Aware Required Checks
Required checks that only run when rules match PR context. Add GitHub-style path filtering to workflows—skip expensive tests for docs-only changes, reducing CI cost and noise.
PR Dependency Management
Automatic detection of PR dependencies using explicit syntax or base-branch inference for stacked PRs. Enforces merge order to prevent child PRs from merging before parent PRs.
Policy-Based Automation
Centralized, auditable policy engine that preserves GitHub's merge guarantees. Turns static branch protection into flexible, repository-defined rules without changing your workflow.
