Sablier Labs is Entering Maintenance Mode

Sablier Labs has stopped active product development and entered maintenance mode, with funded maintenance of its interface running through June 2028 while the protocol's smart contracts continue operating onchain. The company cites weak Q1 2026 usage and revenue, customer launch delays tied to deteriorating crypto markets, and AI-assisted coding making its products cheaper to replicate. Starting July 13, 2026, the official interface stops accepting vesting streams and airdrops with end times after June 2028, and open-ended payment streams are fully blocked. The Sablier EVM contracts' license has also moved up from BUSL 1.1 to GPL, effective July 13, 2026, and the interface is expected to become an open-source public good. Co-founder and CEO Paul Razvan Berg wrote the announcement.
