Bootstrapware Importer VS git-sizer

• Browser-side processing
  Parsing, mapping, validation, and normalization run on the customer’s device. Spreadsheet contents are not uploaded to Bootstrapware.
• Column mapping
  Automatically maps headers using aliases. Users can manually remap columns, and preview remains blocked until all required fields are mapped.
• Typed validation
  Supports string, number, date, email, enum, boolean, URL, required, and field-level unique validation.
• File format support
  Supports CSV, XLSX, TSV, semicolon-delimited, and pipe-delimited files with automatic delimiter detection.
• Multi-sheet Excel
  Excel workbooks include a sheet picker so users can select the correct worksheet before mapping.
• Preview
  Displays counts for the complete file and previews the first 100 rows so users can identify problems before submission.
• Duplicate detection
  Detects case-insensitive duplicates using a configured duplicate key or fields marked as unique.
• Failed-row export
  Exports import-errors.csv with the original field columns and an Errors column for correction and re-upload.
• Localization
  Supports US and EU number formats, MDY or DMY dates, and left-to-right or right-to-left interfaces.
• Configuration revisions
  Teams can edit a draft without affecting live clients, then publish the new configuration when ready.
• Operational webhooks
  Sends HMAC-signed import.completed webhooks containing operational metadata, never spreadsheet contents.
• Downloadable templates
  Generates a template CSV in the browser using the configured schema and field examples.

• 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
