App showcase
Three focused workflows, one launcher ecosystem.
Subchain starts with CardCrop as the public flagship, plus Instaflow and eSniper as private-access workflows that stay clearly scoped while they mature.
Purchases, accounts, license checks, and backend app installs are not wired into this website. Availability is shown plainly until real release channels exist.
Flagship workflow
CardCrop
CardCrop is the most public Subchain workflow: a focused desktop-first tool for cleaning up trading card photos and preparing sharper listing images, with an iPhone capture direction planned.
- Raw photo review
- Crop and cleanup
- Listing-ready export
Mac first, iPhone direction
CardCrop is planned as a free base workflow with separate one-time $1.99 Pro upgrades for desktop and mobile. The website does not process purchases.


Private-access workflow
Instaflow
Instaflow is a private-access creative workflow for owned short-form and social content preparation: organize media, build previews, prepare captions, and keep publishing decisions review-led.
- Prepare source media
- Preview the package
- Keep posting user-approved
Preparation, preview, posting
Instaflow remains private access while the owned-account workflow matures around preparation, preview, review, and publishing handoff.


Private-access workflow
eSniper
eSniper is a private-access auction workflow for tracking lots, rehearsing the final path, setting max-bid intent, and keeping user-controlled decisions at the center.
- Track auction state
- Set max-bid intent
- Keep decisions manual
User-controlled auction discipline
eSniper is framed around watchlists, timing, max-bid discipline, and user-controlled decisions. It stays private access.
