When Simprosys is the right choice
If you only need Google Shopping, Meta, Microsoft, and Pinterest from a Shopify store — and you’re comfortable in the Shopify app ecosystem — Simprosys is well-built, well-supported, and cheaper. It’s a solid tool for what it does.
When to choose Trajekt instead
‣ You need ChatGPT Shopping as UK access rolls out in 2026
‣ You want TikTok Shop, Awin, Amazon, eBay, or OnBuy feeds
‣ You’re on WooCommerce, Magento, or BigCommerce (not Shopify)
‣ You want AI-powered description enrichment at scale
‣ You run multiple stores or manage feeds for multiple clients
‣ You want a UK-built tool with GBP pricing
Frequently asked questions
Simprosys is a popular Shopify app (4.9 stars, 5,000+ reviews) that manages product feeds for Google Shopping, Microsoft, Meta, and Pinterest from within Shopify. It's well-regarded for its Shopify integration and responsive support, with plans starting from $4.99/month for up to 500 products.
Simprosys is a Shopify-only app focused on Google, Microsoft, Meta, and Pinterest. Trajekt works with Shopify, WooCommerce, Magento, and BigCommerce; supports ChatGPT Shopping, TikTok Shop, Awin, Amazon, eBay, OnBuy, and all other major channels; has a no-code rules engine for feed optimisation; and includes AI description enrichment — all things Simprosys doesn't offer.
As of July 2026, ChatGPT Shopping (OpenAI JSONL/SFTP format) does not appear in Simprosys's documented supported channels. Trajekt generates OpenAI-compliant JSONL and delivers it via SFTP automatically — the only UK-focused feed tool to do so.
Simprosys pricing starts at $4.99/month for up to 500 products. Trajekt's equivalent Starter plan is £19/month for up to 500 products. For merchants who only need Google, Microsoft, Meta, and Pinterest from Shopify and don't need ChatGPT Shopping, Awin, TikTok, or AI enrichment, Simprosys is a cheaper option. For merchants who need more channels or ChatGPT Shopping, Trajekt provides more value.
Yes. Trajekt supports all four channels Simprosys supports (Google Shopping, Microsoft, Meta/Facebook, Pinterest) plus 8+ more. You can migrate from Simprosys to Trajekt and get all your existing feeds plus ChatGPT Shopping, TikTok, Awin, and more from one platform.
No — Trajekt uses Shopify's Admin GraphQL API via direct credentials, not a Shopify App Store listing. This avoids App Store fees and gives Trajekt deeper access to your Shopify data including metafields, collections, and SEO fields that App Store integrations typically can't access.
For small Shopify stores wanting just Google Shopping and Meta with minimal setup, Simprosys is a solid choice at lower cost. If you want ChatGPT Shopping access as UK rollout expands, or if you need Awin, TikTok, or a no-code rules engine, Trajekt's free plan (50 products) lets you test before committing.
