Extended definition
Software philosophy that prioritizes data storage on the user's device, NOT on the provider's cloud. Advantages: privacy, offline, real ownership.
Context and application
Local-first isn’t just technique, it’s a philosophy chosen in trade-off with cloud-first. Advantages: zero infrastructure costs (you don’t need to scale), zero breach risk on your side (you don’t have client data), zero DPA with sub-processors (none exist), 100% offline operation. Costs: larger bundle size (Electron 150-180MB), multi-device sync isn’t free (requires manual implementation or opt-in cloud sync), update flow more complex than “refresh tab”. See our behind-the-build article for complete pro/con arguments of choosing local-first.
