Supabase Releases Iceberg-JS v1.0.0, Marking Stable Milestone.

Supabase has released iceberg-js v1.0.0, marking the first stable version of its JavaScript library for working with Apache Iceberg table formats. The v1.0.0 designation signals that the project has moved beyond experimental status and is now considered production-ready.

Announced on LinkedIn, the release represents a significant milestone for developers building data applications that need to interact with Iceberg tables directly from JavaScript environments. Apache Iceberg is an open table format designed for large analytic datasets, offering features like schema evolution, hidden partitioning, and time travel queries.

The library provides JavaScript developers with native access to Iceberg table metadata and operations without requiring a separate query engine or data processing framework. This matters for teams building applications that need to read Iceberg table structures, query metadata, or integrate Iceberg-based data lakes into Node.js or browser-based workflows.

Iceberg has gained traction as a standard for managing massive datasets in cloud data lakes, supported by platforms including AWS, Snowflake, and Databricks. JavaScript tooling for Iceberg has historically lagged behind Python and Java ecosystems. A stable v1.0.0 library lowers the barrier for web developers and Node.js engineers to work with these datasets.

While Supabase is best known for its Postgres-based backend platform, the company has expanded its tooling ecosystem to support broader data infrastructure patterns. The move to v1.0.0 suggests Supabase sees demand from users working with both transactional Postgres databases and analytical data lakes built on Iceberg.

Reaching v1.0.0 typically indicates that the API surface is stable, breaking changes will be avoided in future minor releases, and the library has undergone sufficient testing to support production workloads. For teams evaluating whether to adopt iceberg-js, this version milestone provides a clearer signal of maturity than pre-release tags.

The release follows Supabase's broader pattern of investing in developer tooling around open source data infrastructure. The company recently added binary payload support to Realtime Broadcast, expanded CLI capabilities for schema management, and raised a $500 million Series F at a $10 billion valuation in early June 2026.

Developers interested in using iceberg-js can find the library on GitHub and npm. The v1.0.0 release makes it easier to build JavaScript-based data applications that interact with Iceberg tables, whether for metadata inspection, catalog integration, or building lightweight query interfaces without a full data warehouse stack.
