Not in the ranking
We could not measure these products with our method, so they are listed here instead of being scored. This says something about our method, not about the vendor.
- Adobe Target – We found no product-specific domain: adobe.com is the group front page for its whole product range.
- Firebase Remote Config – We found no product-specific domain: firebase.google.com covers the whole Firebase platform at once.
Narrow it down
Each of these lists the Feature flags and experimentation vendors that meet one condition, with the source for each, and appears only where at least 8 of them meet it.
- Feature flags and experimentation vendors with public pricing 18
- Feature flags and experimentation vendors with a status page with history 9
- Feature flags and experimentation vendors with a named privacy contact 13
