The studio
How we build
A smithy, not a factory. Fewer things, made properly.
Craft over volume
One app finished properly beats five shipped half-done. Every screen, empty state, and error message gets designed.
Reliability is a feature
Merchants run their businesses on these tools. Monitoring, retries, and failure states are part of the product, not an afterthought.
Privacy by default
Customer data is encrypted at rest, deletion flows are built in, and there's no ad-tech anywhere. The policies published on this site are the ones the apps follow.
A human answers
No chatbots, no outsourced tiers. Open a request in the support portal — or email support@cartsmith.dev — and it's the people who wrote the code who reply, usually within a business day.
