I use Liberapay and have been pretty happy with it. Have found quite a few of the people and projects to which I would like to donate, but not all.
This looks really cool! Didn't know anything like it existed
Open collective let's you do this I think.
Non profits might be good candidates, in particular the software in the public interest is governed by a board elected by open source contributors. From it's website:
Donations to SPI that are not marked for a particular project will be distributed to the projects that are currently affiliated with SPI as needed, and/or used for SPI's own expenses.
Definitely Open Collective.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
