WHEN DOES IT MAKE SENSE TO SWITCH FROM REX?

Four reasons people leave.

Decision triggers, not marketing. If two or more apply, your shortlist starts with the apps named below each card.

Pricing has outgrown your usage

If your usage of Rex has crossed a pricing-tier breakpoint, per-unit cost is usually where alternatives diverge most clearly. Some apps in the list above carry a free tier; others are paid from day one. Compare the published plans on each alternative's page against your current bill — the gap is the only number worth acting on, and it is specific to your usage.

You need a feature outside the focus

Each Salesforce category has a feature spectrum. The "Similar feature set" badge above marks alternatives whose feature signature most overlaps with Rex. The "Category leader" badge marks apps that may approach the same category from a different feature angle — useful if you want to widen rather than narrow your toolset.

Support response has slowed you down

Support quality is the hardest thing to read from a listing, and it is the most common reason a switch gets made. Read the most RECENT reviews on each alternative's profile rather than the lifetime average — recency is what tells you how the app is supported today, and trailing review velocity is the freshest signal AppRanks tracks.

Your scale has changed since you picked

An app chosen at small scale is not necessarily the one that survives growth. Once catalog size, API rate limits or data-sync volume start to matter, the higher-ranked apps above tend to be the longer-established ones, which is a proxy for how much scale they have already met — not a guarantee. Check each candidate's recent reviews for scale complaints before you commit.
