Sablier Labs has stopped active product development and entered maintenance mode for its token streaming platform. It plans to release its interface as an open-source public good for the community. The shutdown follows a sharp Q1 2026 downturn. Sablier cited customers postponing launches and AI-assisted coding enabling low-cost replications of Sablier's product.

Existing streams, vesting plans, and airdrops are unaffected. As of today, the interface stops accepting new vesting streams and airdrops ending after June 2028, and blocks open-ended streams entirely. Sablier will keep the interface and backend running for existing users through June 2028, then publish a stewardship and hosting plan.
