The record

Purpose: Gemstash is a cache for remote gem servers such as RubyGems.org and a private gem source.
Intended users: The project suggests Gemstash for teams using Bundler across machines, publishing private gems, or repeatedly bundling the same gems.
Upstream sources: Gemstash can fetch from multiple gem sources, and its default source can be changed in its configuration.
Bundler integration: Bundler can be configured to mirror gem sources through Gemstash, with the simpler mirror setup requiring Bundler 1.11.0 or later.
Private gems: Users can push, fetch, and yank private gems using API keys and the RubyGems command line.
Authentication caveat: Private gems and specs are accessible without authentication by default; protected fetching can be enabled in setup.
Access controls: Gemstash API keys can be given specific permissions for pushing, yanking, and fetching gems.
Caching: Gem files are cached indefinitely, while dependency metadata is cached for 30 minutes by default.
Storage and database: Gemstash stores files under ~/.gemstash by default, and supports SQLite, PostgreSQL, MySQL, and MySQL2 database adapters.
Caching backend: The default in-memory cache can be replaced with a Memcached server or cluster.
Server limitation: Gemstash uses Puma and Rack, and its server configuration is not customizable, although the bind address and Puma thread count can be configured.
Monitoring: Gemstash provides a /health endpoint that reports status for its heartbeat, storage, and database.
License: The project is available under the MIT License.
Maintainer: Gemstash is maintained by Ruby Central, which describes itself as a nonprofit supporting Ruby infrastructure.
