Cody is free to use and doesn't strictly require Sourcegraph. It can make use of Sourcegraph APIs (e.g., code search, soon find refs) to improve its context fetching. We hope to integrate other dev tool APIs (e.g., monitoring, tracing, etc.) as well.

Sourcegraph is also free to use and downloadable as a local app (https://docs.sourcegraph.com/app) or you can use sourcegraph.com for open source. Our intention is to sell to teams/companies, while making tools for individual devs free to use. There have been a few cases in the past where we've misstepped and come across as selling to individual devs. If this ever happens, please flag to me (https://twitter.com/beyang) or sqs (https://twitter.com/sqs) directly and we'll correct it.
