Sirius 5 features
ViewForge 9 features
  • Open Source
    Sirius is an open-source platform, which means that it is freely available for developers to use, modify, and distribute. This openness promotes collaboration and innovation in the community.
  • Customizability
    As an open-source project, Sirius offers a high degree of customizability. Developers can tailor the system to meet specific needs and integrate it with other applications.
  • Cost Efficiency
    Being open-source, Sirius is cost-effective compared to proprietary solutions. There are no licensing fees, which makes it attractive for startups and small businesses.
  • Community Support

  • Flexibility
    Sirius allows for flexible deployment options, including on-premise, cloud-based, or hybrid deployments, to suit different organizational needs.

Possible disadvantages

  • Complexity
    Sirius can be complex to set up and configure, especially for users without extensive technical knowledge. This can result in a steep learning curve.
  • Limited Documentation
    While there is community support, the official documentation of Sirius may be limited or outdated, making it challenging for new users to find comprehensive guides and tutorials.
  • Maintenance Burden
    Being open-source, the responsibility for maintenance, updates, and security falls on the user or organization. This can be a significant burden if there's no dedicated in-house technical team.
  • Scalability Issues
    For very large deployments, Sirius might not scale as efficiently as some proprietary enterprise solutions that are optimized for scalability and high performance.
  • Integration Challenges
    Integrating Sirius with other systems can be challenging and may require significant development effort, whereas proprietary solutions often offer plug-and-play integration with popular services.

Questions & Answers

As answered by people managing Sirius 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
