Best Self Hosted Alternatives to BuiltWith

Daily Stars Explorer retrieves and visualizes the complete star history of GitHub repositories, overcoming the 40,000-star limitation of some APIs. It presents daily and cumulative star counts, comparison views, and exportable data for analysis.

Key Features

• Retrieve full star history for a repository (daily and cumulative counts) using GitHub GraphQL to bypass the 40k limit
• Export star history as CSV or JSON (daily and cumulative formats)
• Compare star trends for multiple repositories side-by-side
• Caching layer with a default seven-day cache and on-demand refresh to reduce API load
• Backend implemented in Go and a JavaScript-based frontend; distributed as a Docker image for easy self-hosting
• Aggregation and trend calculations to highlight growth patterns and daily deltas

Use Cases

• Monitor project popularity and growth trends over time for open-source projects
• Compare competing libraries or tools to inform technology selection or benchmarking
• Export historical star data for reporting, research, or further analysis in spreadsheets or external tools

Limitations and Considerations

• Retrieving a complete star history for very large repositories can be time-consuming; some large repos may take minutes to fetch
• GitHub API rate limits apply; a Personal Access Token with appropriate rate allowances is required and can limit throughput (quota per token)
• Error handling and UI polish are limited in some areas; users may encounter edge-case failures that require retries

Daily Stars Explorer is a focused tool for researchers, maintainers, and analysts who need granular historical star data. It is lightweight to deploy and provides exportable datasets for further analysis or reporting.
