James Arthur @thruflo.com · 05/06/2025When you're vibe-coding, you don't want to think about infra. You want to stay in the zone, iterating and expressing yourself. That means having a database inside your sandbox. No glue, no friction, no external services, no free-tier limits. Forkable, disposable, unlimited and zero cost. 063
Reposted by James ArthurElectricSQL @electric.ax · 05/06/2025🧵 More play less infra => vibe coding with the database inside the sandbox. Apps built with AI app builders like @bolt.new usually need to connect to a database to actually work.
