2015 Call for Grant Proposals


The Ruby Association is looking to give grants for development projects related to Ruby implementations, libraries and frameworks, including projects that improve existing software.

If you have a good idea, please submit a proposal. However, please note that we do not intend to fund development projects of Ruby applications for specific purposes because the aim of this grant is to improve Ruby and its environment.

Development Themes

  • Improving Ruby implementation (such as performance improvement and memory consumption reduction.)
  • Scientific libraries for mathematics, science & engineering.
  • Development support tools (such as debugger, profiler and static program analysis tools.)
  • Web (such as libraries for HTTP, HTML, etc., and web application frameworks.)
  • Tools for enterprise systems (such as reporting tools, batch processing tools, migration tools from the other languages to Ruby.)

Grant Size

JPY500,000 (fixed) for each proposal. 

Eligibility for applicants

Any individual or organization can submit one or more proposals.

Selection process

The grant committee will assess the proposals and will select up to a maximum of three projects.
