Manylabs is a nonprofit which makes open science tools for learning and research and is based in San Francisco. We build, document and deploy our tools in collaboration with other scientists, makers and formal and informal educators. We host a workspace, funded by the Moore Foundation, that brings together scientists and makers working on open tools for science. The three story building in San Francisco's SOMA neighborhood includes office space, a maker space and an exhibit hall. Participants apply for six-month periods in which they have free access to office space, workshop space, exhibition space, and community gatherings.
