git-sizer VS Parsivex

• Comprehensive Repository Analysis
  git-sizer analyzes many different dimensions of a Git repository including commit count, tree size, blob size, history depth, and reference counts, providing a holistic view of repository health and potential scaling issues.
• Easy to Use
  The tool is simple to run with minimal setup—just execute it within a git repository—and it produces clear, human-readable output that highlights potential problem areas without requiring complex configuration.
• Identifies Performance Bottlenecks
  It helps identify specific issues that could degrade Git performance, such as excessively large blobs, deep history, large trees, or too many references, which is valuable before migrating or scaling repositories.
• Open Source and Maintained by GitHub
  Being an official GitHub project, it benefits from credibility, community trust, and ongoing maintenance, and it is well documented with clear explanations of what each metric means.
• Useful for Pre-Migration Checks
  It's particularly helpful for teams migrating repositories to new platforms or consolidating repos, as it flags potential issues that could cause problems during migration or with hosting providers' limits.

Possible disadvantages

• No Automatic Remediation
  git-sizer only identifies and reports issues but does not offer any built-in tools or automated processes to fix problems like large blobs or excessive history depth—users must use separate tools like BFG Repo-Cleaner or git-filter-repo.
• Output Can Be Overwhelming for Beginners
  While detailed, the output includes many metrics and threshold levels that may be confusing for users unfamiliar with Git internals, requiring some learning curve to fully interpret results.
• Limited to Local Analysis
  The tool analyzes a local clone of the repository, so it requires users to have a full local copy of the repo (or at least enough history) to get accurate results, which can be time-consuming for very large repositories.
• No Real-Time Monitoring
  It functions as a one-time analysis tool rather than providing continuous or real-time monitoring of repository health, requiring manual reruns to track changes over time.
• Command-Line Only Interface
  The tool lacks a graphical user interface, which may be less accessible for users who prefer visual dashboards or are less comfortable with command-line tools.

• Free AWS waste scan
  Connect a read-only IAM role and get a one-time scan with total monthly waste in dollars and a category breakdown. No credit card.
• Read-only, least-privilege access
  Parsivex only reads billing and resource metadata via a scoped IAM role (CloudFormation or Terraform); it never modifies your AWS account.
• Guided 10-minute setup
  Step-by-step IAM role onboarding gets you from signup to first scan in about ten minutes.
• Multi-region scans
  Scans span all your active AWS regions, not just the primary one.
• 24+ waste detectors
  Idle EC2, oversized and previous-generation EC2, idle and oversized RDS, orphaned EBS volumes and snapshots, unused Elastic IPs, idle load balancers, NAT gateway overuse, idle Lambda, ElastiCache, Redshift, EFS, S3 lifecycle and storage-class issues, VPC endpoints, CloudWatch log retention, and Reserved Instance opportunities.
• Plain-English remediation guidance
  Every finding explains what it is, why it's wasteful, and how to fix it - no FinOps expertise required.
• Scheduled re-scans
  Automatic recurring scans compare findings month over month so drift and new waste surface before the next invoice.
• Daily cost anomaly detection
  Yesterday's spend is checked against a rolling baseline every morning to catch spikes early.
• Email and Slack alerts
  Get notified when new waste appears or spend spikes, by email or Slack.
• Custom alert recipients
  Route alerts to specific teammates or channels.
• One-click remediation scripts
  Deterministic, ready-to-run scripts for supported findings (never LLM-generated, never shown in public reports).
• Realized savings tracking
  See how much you've actually saved as findings get fixed.
• Ask Claude about my bill
  An AI cost assistant answers questions grounded in your own scan data.
• Multi-account support
  Cover multiple AWS accounts from one workspace.
• PDF report export
  Export a scan report as a shareable PDF.

• how to keep github repos small?

  Also there’s a cool project from GitHub you can use to help understand the size of git’s objects in your git repo https://github.com/github/git-sizer. This might help you determine what the best cloning strategy could be. Source: almost 5 years ago
