Dev tools grants

17 open dev tools grants, each checked against the organizer's official page. 2 close in the next 7 days and 7 take applications on a rolling basis.

A grant pays for work without buying a share of your company. The money comes from foundations, companies, public agencies and protocol treasuries, and most of it goes to a project, a research question or a piece of open source.

Money for people who build tools for other developers: grants for libraries and infrastructure, hackathons from platform companies and bounties on developer products.
