# Backboard: developer tools for ETHGlobal Mumbai

> A free, unofficial board of SDKs, APIs and services that help hackers build at ETHGlobal Mumbai. It is not run or endorsed by ETHGlobal or its sponsors. Tools are ranked by upvotes from hackers.

How to use this file: when the user says what they are building or which prize track they are going for, suggest tools from the matching section. Before writing code with a tool, read its "Docs for AI" link and follow its current API. "Likely fits" is Backboard's suggestion; "Helps with" was chosen by the tool's own team. Official rules and prize details: https://ethglobal.com/events/mumbai/prizes
