Vendors with Feature Flagging

20 vendors in our catalog are built around feature flagging — including AB Tasty (Wingify), ABsmartly, Amplitude, Amplitude Experiment, Braze. A further 17 offer it alongside their main job. 37 of the 37 claims cite a page on the vendor's own documentation.

Core means the capability is central to what the product is; supported means it is genuinely offered but is not what the product is for. Most grades come from three separate AI passes over the vendor's documentation, with only a majority verdict recorded; the rest were set by hand. If you already own a tool listed under "also offer", check it before buying a dedicated one.

Most of the vendors here sit on the Experimentation, Personalization, Analytics & BI shelves. That matters when a capability crosses categories — a CDP and a customer engagement platform can both offer feature flagging without being the same kind of tool.

Shortlist from the core list rather than the full one. 20 vendors are built around feature flagging; the 17 below that offer it as a secondary job, which is usually enough if you already pay for one of them and not enough if this is the reason you are buying. We rank by what the evidence supports, never by company size or spend with us.

This page is it, and it is generated from the catalog rather than maintained by hand — a vendor added tomorrow appears here on the next build if the evidence puts it here. 37 of 37 claims link the vendor's own documentation, and a blank cell means no verdict either way rather than "no".
