Overview

Look up exact Ruby gems by name or search RubyGems in bulk and get back clean, structured JSON for every gem: current version, all-time and per-version download counts, authors, description, licenses, runtime dependencies, and homepage, source, documentation and project links. Built for Ruby developers, dependency auditors and OSS analysts who need reliable, ready-to-use gem data. Export to JSON, CSV or Excel.

Features

🎯 Exact lookups — pass precise gem names like rails, sinatra or nokogiri and get one clean record each.
🔎 Bulk search — run a free-text query (http client, background jobs) and collect matching gems up to your limit.
📊 Download metrics — capture both all-time downloads and current versionDownloads for popularity and trend analysis.
🧾 Licenses & dependencies — every record includes licenses and the gem's runtime dependencies for fast auditing.
🔗 Ready-to-use links — homepageUri, sourceCodeUri, documentationUri and the canonical projectUri.
🧩 Integrations — plug the output straight into n8n, Make, Zapier and more.
⚙️ Reliable by design — retry-with-backoff and graceful handling of missing gems so runs finish cleanly.

What you get

Each gem becomes one clean JSON record.

FAQ

How many gems can I scrape per run? Add any number of exact gem names in the gems field and collect up to maxItems (5000) more from a search query — all in one run.

What's the output format? Structured JSON — one record per gem with fields such as version, downloads, versionDownloads, authors, info, licenses and dependencies. Export as JSON, CSV, Excel or via the API.

What happens to a gem name that doesn't exist? It's returned as a record with ok: false and an error, so a typo never breaks the run — every other gem is still scraped.

Can I use this with n8n? Yes. Run the actor from the Apify node for n8n and map the gem records straight into your workflow — enrich a dependency list, trigger alerts on new versions, or sync gem data into a database or spreadsheet.

Can I connect this Actor to other apps? The RubyGems Scraper works with almost any cloud service or web app thanks to integrations on the Apify platform: Make, Zapier, Slack, Google Drive and many more, plus the Apify API, JavaScript/Python clients and MCP. Or use webhooks to trigger an action whenever a run finishes.

Tracking packages across ecosystems? Pair this with our other developer-data scrapers:

Notes

This actor reads only publicly available gem data from RubyGems. It is an independent tool and is not affiliated with, endorsed by, or sponsored by RubyGems.org or Ruby Central; "RubyGems" and "Ruby" are trademarks of their respective owners. Original clean-room implementation.

Input

Field	Type	Description
`gems` Exact gem names	array	Look up specific Ruby gems by their exact name, e.g. "rails", "sinatra", "nokogiri". Combined with any search results in the same run.
`search` Search query	string	Free-text RubyGems search (matches gem name and description), e.g. "http client". Matching gems are collected up to Max items.
`maxItems` Max items (search)	integer	Maximum number of gems to collect from the search query. Exact gem names above are always fetched in addition to this. Default: `100`
