Prefems VS git-sizer

• Tier lists (prefems)
  Rank anything with 2 to 12 tiers, using images or plain text. You name the tiers yourself.
• Rank anything with 2 to 12 tiers, using images or plain text. You name the tiers yourself.
  Other people re-rank your tier list (prefem) their own way, so you can see item by item where they agreed with you and where they did not.
• Global Hopinion
  Every ranking a subject has ever received, added up into one shared community ranking from S down to F.
• Opinion Explorer
  A permanent page for every subject, showing the community tier distribution with percentages and vote counts. Two subjects can be compared side by side.
• Controversiality score
  A 0 to 10 score per subject, so you can tell a settled opinion apart from a split one.
• Pros and cons
  Short notes written by the community on each subject, voted up or down by everyone else.
• Subject library
  A shared library of things to rank, or add something nobody has ranked before.
• Nests
  Communities built around one interest, each with its own tags, standards and moderators.
• Feeds
  Sort by trending, newest, or only the people, nests and subjects you follow.
• Comments
  Text, images and GIFs, with replies, mentions and pinned comments.
• Drafts
  Save a list and finish it later, or send one to someone else to complete.
• Levels and reputation
  Levels grow with what you post. Reputation reflects how other people vote on it.
• Account
  Free. Sign in with email, Google or Apple.

• 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.

• 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
