Features and specs

What each product offers, as listed by its team.

Ktor 5 features
ViewForge 9 features
  • Asynchronous and Non-blocking
    Ktor is built on top of Kotlin coroutines, which allows it to handle high concurrency with ease through non-blocking I/O operations, providing better performance under load compared to traditional blocking frameworks.
  • Kotlin-first
    Being designed specifically for Kotlin, Ktor fully leverages Kotlin's language features like DSLs and coroutines, providing a concise and readable syntax that is well integrated with Kotlin's ecosystem.
  • Flexible and Modular Architecture
    Ktor offers a highly modular architecture, allowing developers to include only the components they need, which can help reduce the application's footprint and tailor the application to specific use cases.
  • Multi-platform Capabilities
    Ktor can be used to develop applications that target different platforms, such as JVM, Android, and native, making it a suitable choice for multi-platform projects.
  • Strong Community and Active Development
    With JetBrains backing and a growing community, Ktor benefits from active development, continuous improvements, and a wealth of community-contributed plugins and resources.

Possible disadvantages

  • Relatively Young Framework
    Being a newer framework compared to some established ones like Spring, Ktor might have fewer resources, tutorials, and community-driven content available, which could present a learning curve for new users.
  • Less Mature Ecosystem
    Due to its relative youth, Ktor's ecosystem might not be as mature or extensive as more established frameworks, potentially requiring extra effort when integrating with third-party tools and services.
  • Limited Built-in Features
    While Ktor's modularity is a strength, it also means that some features available out-of-the-box in bulkier frameworks may require additional configuration or setup, potentially increasing development time for some projects.
  • Documentation Gaps
    Though improving, Ktor's documentation may not be as comprehensive as that of older frameworks, which can cause challenges when developers seek guidance on implementing specific features or troubleshooting issues.
  • Requires Kotlin Expertise
    Given that Ktor is designed specifically for Kotlin, developers without prior Kotlin experience may face a steeper learning curve when working with this framework compared to more language-agnostic tools.
  • Fitment Information
    Cascading Year/Make/Model fitment search, up to four levels
  • Vertical integration nobody else has
    8 built-in vertical templates, plus custom templates on paid tiers
  • Shopify Metaobjects
    Fitment stored as native Shopify metaobjects — your data survives uninstall
  • Smart Data Processing
    Smart Parse: extract fitment from existing product titles and descriptions, with confidence scoring
  • CSV Import/Export
    CSV import with fuzzy matching and a coverage dashboard
  • ACES / PIES
    ACES / PIES import and NHTSA VIN decoding
  • My Garage
    Saved-vehicle garage, compatibility table, and product-page fit notice
  • Context Aware Fitment Search
    Collection-level fitment assignment
  • No Obligations
    Free tier with no expiry, up to 50 products

Questions & Answers

As answered by people managing Ktor and ViewForge.

What makes your product unique?

ViewForge's answer:

Three things. (1) Data ownership: ViewForge writes fitment as Shopify metaobjects native to your store — most competitors store fitment in their own database. (2) 8 verticals out of the box: auto, motorcycle, tractor, marine, power equipment, bicycle, printer, electronics — most competitors are automotive-only. (3) Smart Parse: extract fitment automatically from your existing product titles and descriptions instead of re-typing everything.

Why should a person choose your product over its competitors?

ViewForge's answer:

Data ownership. Fitment lives in your Shopify metaobjects, so uninstalling does not take your compatibility data with it. Convermax, EasySearch and PartFinder all keep it in their own databases, and getting it back depends on their export tooling on the day you cancel.

Cost at the low end. The search widget, the compatibility table on the product page and the saved-vehicle garage are all on the free tier, up to 50 products, with no expiry. EasySearch puts the table and the garage behind its $75/month Premium plan. Convermax starts at $250/month.

Automotive and non-automotive coverage. Eight built-in templates, and fully custom templates from $19/month, for catalogs that do not decompose into Year/Make/Model at all.

How would you describe the primary audience of your product?

ViewForge's answer:

Shopify merchants whose customers need to know whether a part fits before they will buy it — and who do not have an engineer on staff to build that themselves.

Concretely: auto and truck parts retailers, powersports and motorcycle dealers, tractor and agricultural parts sellers, marine and outboard suppliers, small-engine and power equipment stores, bicycle and e-bike component shops, printer supply merchants, and electronics accessory sellers.

Catalog sizes run from a few dozen products on the free tier up into the tens of thousands; it is running in production on a catalog of roughly 40,000 SKUs. The common thread is not the industry — it is that "does this fit my thing" is the question deciding the sale.

What's the story behind your product?

ViewForge's answer:

ViewForge came out of agency work. Normal View was building for a parts retailer running roughly 12,000 SKUs who needed fitment search, and every app we evaluated stored the merchant's compatibility data in the vendor's own database.

That is a strange trade when you look at it directly. Fitment data is genuinely expensive to produce — it is weeks of work — and the merchant would not own the result. It would belong to whichever app happened to be installed that year.

Shopify metaobjects made a different answer possible: write fitment as native structured data inside the merchant's own store. The theme reads it, the Storefront API queries it, Admin GraphQL exports it, and it is still there after an uninstall. That decision is what the rest of the app is built around.

Everything else came from real catalogs rather than a roadmap. Eight verticals exist because a tractor catalog is not Year/Make/Model. Smart Parse exists because that retailer had already written fitment into 12,000 product titles, and nobody was ever going to retype them.

Which are the primary technologies used for building your product?

ViewForge's answer:

  • TypeScript
  • Shopify metaobjects, as the fitment data store
  • Shopify theme app extensions for the storefront components: fitment search, saved-vehicle garage, compatibility table, product-page fit notice
  • Shopify Storefront API, for querying fitment from the theme
  • Shopify Admin GraphQL API, for writing and exporting fitment records
  • NHTSA vehicle database, for VIN decoding
  • ACES and PIES XML parsing, for automotive catalog import
