Supabase Launches TanStack DB Adapter With Live Queries and Realtime Sync.

Supabase has released an alpha version of @supabase-labs/tanstack-db, a collection adapter that bridges TanStack DB with Supabase's real-time database infrastructure. The adapter introduces live queries, optimistic mutations, and automatic synchronization through Supabase Realtime, all with full TypeScript support.

The launch positions Supabase as a backend option for developers building with TanStack, a suite of JavaScript libraries for managing asynchronous state. By providing a first-party adapter, Supabase aims to simplify real-time data workflows for developers who already use TanStack's query and table libraries in their applications.

The adapter supports several features designed for real-time applications:

• Live queries that automatically refresh when underlying data changes
• Optimistic mutations for instant UI updates before server confirmation
• Automatic Realtime sync through Supabase's existing Realtime infrastructure
• Full TypeScript typing for type-safe database operations

Because the release is in alpha, Supabase is actively seeking developer feedback. The company has not yet published detailed documentation or migration guides, though developers can experiment with the adapter through the @supabase-labs npm scope.

The timing follows Supabase's recent $500 million Series F funding round at a $10 billion valuation, led by GIC. The company has been expanding its developer tooling, including recent work on CLI improvements for declarative schema management and integrations with platforms like Perplexity Computer.

Supabase has built its platform around Postgres, offering authentication, storage, and real-time subscriptions as managed services. The TanStack adapter extends this by letting developers use TanStack's familiar query patterns while Supabase handles the database layer and real-time updates.

For teams already using Bubble, WeWeb, or other no-code tools with Supabase backends, this adapter could provide a path to more complex client-side state management when scaling beyond form-based applications. Developers working in Cursor or Replit can test the integration directly in their existing Supabase projects.

The alpha status means breaking changes are likely as the team refines the API based on early adopter feedback. Developers interested in testing should expect to adjust their implementations as the adapter matures toward a stable release.

Supabase has not announced a timeline for moving the adapter out of alpha or whether it will remain under the @supabase-labs scope or graduate to the main @supabase npm organization. The company is collecting feedback through its GitHub repositories and community channels.
