Independent app studio
Focused apps for Shopify merchants
One app, one job, done right. Every tool we ship solves a single merchant problem you can describe in one sentence — with minimal permissions and honest pricing.
Apps
The catalogue
Each app has one job, its own guides, its own privacy page, and a plan you can understand at a glance.
Solvi Barcode Labels
Print barcode labels right the first time: unique codes, true-size sheets, ready in minutes.
One entry, on purpose
We would rather ship one dependable tool than ten half-finished ones. A new app joins the catalogue only once it clears the same bar as this one: minimal Shopify scopes, GDPR webhooks wired and verified, and end-to-end tests passing before submission.
How we buildHow we build
Four rules every app follows
These are not marketing lines — they are constraints we apply before a single line of code is written, and they are verifiable in every app we publish.
One app, one job
Every app solves a single problem you can describe in one sentence. No suites, no feature creep — a tool you understand in the first minute.
Minimal permissions
Each app requests only the Shopify scopes it needs to do its job. If a feature would require broader access than it is worth, we do not build it.
What you see is what you get
Previews match the final output, plan limits mean what they say, and nothing important hides in fine print.
Quotas, not credits
Paid plans come with a monthly quota that resets on its own. You never buy credit packs and never watch a balance expire.
