Which to choose?
- Pick DummyJSON if…you want zero friction — no account, no key, just call the endpoint. Also good if dev-tools data without signup is a hard requirement.
- Pick JSONPlaceholder if…you want zero friction — no account, no key, just call the endpoint. Also good if dev-tools data without signup is a hard requirement.
- Use both if…one goes down — they serve the same dev-tools use case from different data sources, so you can implement a quick fallback.
