SoftwareSilo and Webkul both show downloadable files in Magento, but their starting points differ. SoftwareSilo builds a customer document library and can also place files on products. Webkul builds product and category attachments, then carries product context into order history and email.
The core difference
| Question | SoftwareSilo | Webkul |
|---|---|---|
| What owns the document? | Customer, customer group, product, or linked sales document | Product or category |
| Main customer location | My Documents | Product and category pages |
| Customer-group restriction | Yes | Yes |
| Categories and reports | Document categories, tags, download report | Category attachments, view reports by customer group and period |
| Password, validity, maximum downloads | Yes | Not stated on the reviewed page |
| Order context | Links to orders, invoices, shipments, and credit memos | Product attachments in order history and order email |
| GraphQL | Separate add-on | Published as included |
| Hyva | Separate add-on | Selectable support option on product page |
Choose SoftwareSilo for account-owned files
A contract, project certificate, individual price sheet, or service report belongs to a customer relationship. SoftwareSilo lets administrators assign customers and groups, set validity and download limits, add passwords, publish selected files publicly, and organize the library with categories and tags.
Product assignment is available, but it is one placement among several. Documents can also appear alongside sales documents. Separate add-ons cover REST/SOAP, GraphQL, CSV import/export, and Hyva.
Choose Webkul for catalog-owned files
Webkul's product page describes attaching files to products and categories through several admin entry points. Merchants can restrict previews by customer group, manage file icons, show attachments in product overview, report views, and carry attachments into order history and order email. The vendor publishes REST and GraphQL work in its changelog and current feature list.
This model suits a catalog where every buyer of the same product should see the same manual, certificate, license, or specification. Category attachments also help when a file applies to an entire product family.
Where both may be needed
A manufacturer might use product attachments for public data sheets and a customer library for account-specific calibration certificates. Combining two products can be reasonable when the ownership rules are genuinely different. Avoid publishing the same file in two places unless one system remains the clear source and updates both consistently.
