Yes, Snapshot itself is free to use and does not charge any fees for setting up a space, creating proposals, casting votes, or executing decisions. However, to create a space, you need an ENS domain, which you must purchase from https://ens.domains. In addition, while Snapshot’s core features are offchain and do not inherently require gas fees, deploying a Snapshot X space may involve paying gas fee. If you decide to sponsor gas costs for users to submit proposals or cast their votes on Snapshot X, you will also need to cover those fees. Despite these extra costs arising from external factors, Snapshot itself remains free.
