The differences that decide it
Per-item fees or a flat plan
Customily charges US$49 a month plus a fee for every unique personalised item, starting at US$1 each, so 100 personalised items in a month adds US$100. Kastomise has no per-item or per-order fees: you pay for the number of product configs, however many orders you take.
Creative tools: Customily’s strength
Customily includes AI photo tools, thousands of clipart assets, ready-made designs, and maps, star maps and calendars. Kastomise has none of these; it focuses on placing the shopper’s own photos and text accurately on your print area.
Print files
Kastomise gives a CMYK PDF for each print area, with an embedded colour profile, at the resolution you set per product. Customily offers more formats, including EPS, AI and DXF, which suits engraving and laser cutting, with resolution and colour-mode settings.
A 3D view of the finished design
On Pro, Kastomise shows the shopper’s finished design on a 3D model of your product, with a colour picker for each area; Studio adds a 3D teaser in your gallery. Customily’s site and listing don’t mention 3D.
Logic, add-ons and print-on-demand
Customily has conditional logic, charges for options by adding a priced product to the cart, and connects to about a dozen print-on-demand partners. Kastomise has none of these; you price personalisation through a Shopify variant and print from the files.
Where each one works
Customily connects natively to Etsy, Amazon, WooCommerce and more, with a US$299 Standalone plan for other platforms. Kastomise runs on Shopify, and its hosted page, included in every plan, works with any other store through a design code.
Pricing compared
Customily is US$49 a month per platform, plus a fee for every unique personalised item: US$1 each for the first 100 in a month, falling to US$0.50, US$0.25 and US$0.10 as volume grows, with no percentage commission. So a month with 100 personalised items costs US$149. Its Standalone plan, for platforms such as BigCommerce, Wix and Squarespace, is US$299 a month plus the same item fees. Kastomise is free for one product config, then starts at A$69 a month (US$50 through Shopify) for 5 product configs, the same however many orders you take. Customily’s plan covers unlimited products, while Kastomise counts product configs (one config can be linked to as many products as you like), and Kastomise’s 3D view needs the Pro plan, from A$179 a month (US$127 through Shopify).
