Why these are free
Every tool here runs in your browser rather than on a server. That means no upload, no storage, no queue — and no per-user cost to us, which is why there is no paid tier and nothing is locked behind an account.
We are a software team that builds custom internal tools for companies. These are a working sample of that, kept genuinely useful rather than crippled into an advert.
Need a tool like this for your own workflow?
We built ShelfReady in-house. If your team is doing something repetitive by hand — image pipelines, catalogue prep, order admin — we build custom tools for it. Specs are $1,000; MVPs start at $3,000.
