Flexify builds your Meta product feed: it manages categories, titles, images and fields, adds languages and currencies, and turns collections into Meta product sets. Rabbot watches what Meta does with it. It connects to Google Merchant Center and Meta, notifies you when a product is disapproved or rejected, and on paid plans cross-checks the feed against your live storefront every day. SEO apps edit. Feed apps build. Rabbot watches both. If you need a tool to build and shape the Meta catalog, Flexify is the closer fit. If you need to know the day a price, a stock level or a missing GTIN puts a product at risk, Rabbot is. Most stores selling through Meta run both.
What Flexify does
The App Store listing is titled “Flexify: Facebook Product Feed”. On 2026-09-29 it showed a 4.4 rating from 154 reviews, a launch date of November 4, 2015, and the Built for Shopify badge (listing).
Its headline reads: “Customize your Meta product feed. Build enhanced catalogs. Create unique Facebook & Instagram ads.” It says Flexify “integrates with Shopify’s Facebook & Instagram Sales Channel, or can be configured as your primary integration”. The bullets include “Manage your product categories, titles, images, and all other fields”, “Add multiple languages and currencies”, and “Create flexible product segments. Shopify collections or tags → Meta product set”.
The listing’s feature tags include error validation and GTIN management; its description text does not describe either.
Pricing as listed, in USD: a Free-Forever tier (up to 1,000 products, sync every 24h); Premium - SMALL $29 / month (2,000 products, 500 free image optimizations per month); Premium - MEDIUM $49 / month (5,000 products); Premium - LARGE $79 / month (9,000 products). Hourly sync is +$20. Paid plans have a 30-day free trial.
What Rabbot does
Rabbot monitors your live storefront and your channel verdicts. It does not build a catalog.
For feeds, on paid plans, it connects to Google Merchant Center and Meta and notifies you when a product is disapproved or rejected (Meta channel, Google channel). On paid plans it cross-checks the feed against the live storefront every day: price, availability, GTIN, brand and missing data. Mismatches are reported as disapproval risk (feed monitoring, feed alerts). TikTok catalog verdicts are TikTok (Beta): it connects the same way, and Beta means the channel is still being polished.
It also checks the pages that earn your money: canonical tags, structured data, redirects, noindex, 404s, titles and descriptions, headings, hreflang, the password page and a missing add-to-cart. One alert per problem, and nothing closes until a live recheck confirms the fix. A weekly digest is on every plan, Slack alerts on paid plans.
Rabbot asks Shopify for three read permissions (read_products, read_content, read_themes) and takes no customer or order data. Plans: Free $0 (20 URLs, no card), Starter $19/mo (1,000 URLs, one feed channel), Growth $39/mo (5,000 URLs, up to three channels), Pro $79/mo (15,000 URLs, all channels).
Rabbot does not build, map, optimise or submit a feed, runs no campaigns, and has no reviews yet.

Where Flexify is the better pick
If the Meta catalog is the problem, Flexify does the work and Rabbot does not. It edits categories, titles, images and every other field, builds language and currency feeds, segments products into Meta product sets, optimizes images and syncs the result. It has a Free-Forever tier for up to 1,000 products. Rabbot builds nothing, maps nothing and submits nothing. It runs no campaigns.
Its free tier covers up to 1,000 products in the Meta feed. Rabbot’s free plan watches 20 URLs and connects no channel. Flexify has 154 App Store reviews (2026-09-29). Rabbot has none yet.
Where Rabbot is the better pick
Rabbot is built for the part after the catalog syncs: what Meta or Google decided and whether your storefront still matches what you sent. It also covers Google Merchant Center, so one app watches both channels. Starter is $19 a month against $29 for Premium - SMALL, and Free watches 20 pages with no card.
The feed side
On paid plans Rabbot connects to Google Merchant Center and Meta and notifies you when a product is disapproved or rejected. On paid plans it cross-checks the feed against the live storefront every day, price, availability, GTIN, brand and missing data, and flags the mismatch as disapproval risk. TikTok (Beta) catalog diagnostics are read daily on paid plans.
The Flexify listing tags error validation and GTIN management. It does not describe alerts after submission (checked 2026-09-29).
Can you run both?
Yes. Flexify builds the catalog and syncs it. Rabbot reads the live storefront and the Meta and Google verdicts after it goes out. If a product page price drifts from the price in the catalog, or Meta rejects a product, Rabbot reports it.
FAQ
Do I still need a feed app if I install Rabbot? Yes. Rabbot does not build, map, optimise or submit a feed. A feed app produces the catalog. Rabbot watches the live storefront and the channels after it is sent.
Is Flexify free? The listing shows a Free-Forever tier with up to 1,000 products and a 24-hour sync. Premium - SMALL is $29 per month, with hourly sync at +$20 (2026-09-29).
Does Flexify tell me when Meta rejects a product? The listing does not describe alerts after submission (checked 2026-09-29). Rabbot notifies you when Meta or Google Merchant Center disapproves or rejects a product.
How do I find products rejected from my Meta catalog? Meta reports review results per product. On paid plans Rabbot connects to Meta, pulls those verdicts daily and notifies you of rejections (Meta channel).
Does Rabbot work with a catalog built in Flexify? On paid plans Rabbot reads your Meta results and your live storefront, so it does not matter which app built the catalog. The Google Shopping feed apps comparison covers Flexify beside five other feed apps.
