DAOhaus

Snapshot began as gasless off-chain governance for DAOs with flexible voting strategies and validation plugins, and the team later launched Snapshot X, a modular onchain voting stack that keeps execution trust-minimized while still minimizing gas through clever proving and cross-chain voting power accounting.

Aragon OSx is onchain DAO framework infrastructure for launching modular organizations that govern treasuries and protocol parameters with audited contract primitives.

Agora is an onchain governance application used by protocols including Optimism, ENS, and Uniswap to run delegate voting. It is a Next.js application a DAO deploys rather than a library a builder imports.
