Instant joins OpenAI after 17,000 users

InstantDB says its team is joining OpenAI after serving more than 17,000 users, whose 400,000 apps processed about 2.5 billion transactions, according to Instant’s announcement. New signups are closed, existing cloud users have 12 months to migrate, and hosted apps shut down on August 31, 2027, with backups available for another year. Builders using agent-generated apps should treat backend ownership as part of continuity planning, much as the archive’s analysis of hosted Codex apps treats the runtime as part of the product.
