Introducing Neon Labs

Neon has launched Neon Labs, an experimental platform for early Postgres tooling built around Lakebase Postgres, beginning with an Upgrade Assessment and Migration Assistant designed to help users prepare for major-version migrations. The read-only assessment analyzes a Neon project against version-specific rules to identify blockers, warnings, extension compatibility, schema issues, and logical-replication risks, while the assistant recommends migration approaches based on database size and downtime needs, including managed imports, pg_dump/pg_restore, and logical replication. For logical replication, the tool automates or monitors tasks such as schema setup, publication and subscription configuration, replication lag, sequence alignment, row-count checks, ANALYZE, rollback, and teardown, though users must still pause writes and change application connection settings during cutover. Neon emphasizes that the tools are experimental and should only be used with development or test workloads for now, while production users should follow established upgrade paths. The initiative addresses the complexity of Postgres upgrades, particularly as Postgres 19 approaches and Postgres 14 nears end of support, since Neon projects are tied to their original major version and require migration to a newly created target project. Neon Labs is built with Next.js, TypeScript, the Neon API, and direct catalog queries, does not store assessment data, separates assessments from migration actions, and is available both as a hosted service and an open-source local deployment.
