Every free feature flags tier that clears our bar in 2026: 5 offers meet the criteria and 3 offers are demoted with a named reason. Recorded changes and a published ranking method. We could not confirm today's terms for 2 of them: on 1 the page we cite did not answer, and on 1 our own read did not confirm them. Each row says why.

Best Free Feature Flags Tools

Every free feature flags tier that clears our bar today. Updated 2026-11-14.

5 offers meet our criteria for this category. Of those, 3 carry no recorded change to the terms we publish, 1 a recorded narrowing, and we publish no durability signal for 1. The Durability column below says which offer is in which group, and links the dated record behind every change. We withhold the class where the pricing page does not resolve or states no amount, tier or rate we can read, where we refused the last read, where the listing is gated, or where a narrowing in our records cites no source or no archived copy of the vendor's page has confirmed it. We do not rank these by how much you get, because the limits are not comparable without reading each vendor's page. They are listed in an order that rotates daily. Here is how that order is derived. There is no top slot here to sell.

Why trust this data? Every free tier is verified against the vendor's pricing page with dates tracked. We monitor 513 pricing changes and flag vendors that have reduced or removed free tiers. Rankings start every offer at zero and can only demote. There is no signal a vendor can acquire, lobby for, or buy — there is nothing to add. A record reaches a function page when its category names the function or when it carries a subtype label that names the function. Adding a label to a record publishes it here; removing one withdraws it. No page holds a list of vendors. See all 9 feature flags offers →

Demoted — and exactly why

These offers reach this page too and rank below the list above. Each one names the recorded fact behind it. A recorded limit reduction, pricing restructure or new restriction is shown on every surface where the offer appears, with its date and summary — but it does not move rank. We have change records for only 16% of vendors, and disproportionately for well-known ones, so ranking on them would demote the vendors we happen to watch most closely.

Abby

Free

Open-Source feature flags & A/B testing. Configuration as Code & Fully Typed Typescript SDKs. Strong integration with Frameworks such as Next.js & React. Free plan: 1,000 events/month, 3 feature flags/remote configs, 1 A/B test, 5 environments. We could not read the page we cite for this offer when we last looked, on 2026-11-11, so we cannot confirm these terms today.

−1 stale_verification We cannot confirm this offer: 1 consecutive re-check attempt has failed (most recently 2026-11-11 — timeout), never confirmed since it was indexed. This is our inability to verify, not a change by the vendor. (a limit of ours, not a change by the vendor)

−1 stale_verification Our last read of the vendor's pricing page, on 2026-10-30, found a change we then refused to record, because it named no figure that had moved. This is our confidence in the record, not a change by the vendor. (a limit of ours, not a change by the vendor)

This is our inability to verify, not a change by the vendor. (a limit of ours, not a change by the vendor)

Frequently Asked Questions

What is the best free feature flags tool in 2026?

We publish no ranking of these. Nothing we record measures popularity or generosity, so naming a best or a top few would be our preference rather than our data. We hold 5 free feature flags offers that clear our bar, each listed with the terms we publish and the date we last read them. Our ranking rule is published at /criteria.

Which of these free feature flags tiers have held their terms?

5 offers meet our criteria for this category. Of those, 3 carry no recorded change to the terms we publish, 1 a recorded narrowing, and we publish no durability signal for 1. The Durability column below says which offer is in which group, and links the dated record behind every change. We withhold the class where the pricing page does not resolve or states no amount, tier or rate we can read, where we refused the last read, where the listing is gated, or where a narrowing in our records cites no source or no archived copy of the vendor's page has confirmed it. We do not rank these by how much you get, because the limits are not comparable without reading each vendor's page.
