RubyGems: common questions

Is RubyGems free to use?

Yes — RubyGems is a free developer tools API. Free tier: Free — limits not published. Whether the free tier allows commercial use is unclear — check the provider docs.

Does RubyGems need an API key?

No — RubyGems needs no API key or signup. You can call it straight away; rate limits still apply (Unpublished).

Can I call RubyGems from the browser?

Yes — RubyGems returns CORS headers over HTTPS, so front-end code can fetch it directly with no backend proxy. Use the fetch snippet on this page, or hit "Run live" to try it now.

Is RubyGems up right now?

RubyGems is catalogued but not yet on our probe schedule, so we don't publish a live status for it. Check the provider's own status page or docs for its current state.
