LaunchDarkly alternatives: what a flat-priced flag service can and cannot do

If you are here because of seat pricing, the premise is out of date. LaunchDarkly's pricing page says it plainly: “No per-seat pricing. Invite your whole team; pricing is based on usage.” Seats are free on every tier, the free one included.

The bill is driven by client-side monthly active users, service connections and AI runs instead. This is worth stating first because most pages ranking for this query still open with the seat argument, and a buyer who clicks through to the pricing page stops believing the rest of the article.

So the question is not whether you pay per person. It is whether you want a meter at all, and whether you want a platform or a switch.

Figures checked against launchdarkly.com/pricing on 8 September 2026. Usage pricing moves, so check it yourself before you quote it anywhere that matters.

A comparison that skips past LaunchDarkly's free tier is selling you something. Unlimited flags and unlimited seats with no time limit is a real offer. If your flags are evaluated server-side and never reach a browser, the 1,000 client-side MAU ceiling may never bind at all, and you can sit on Developer indefinitely.

If you are evaluating flag tools with no budget, start there. Three things eventually push people off it:

• Browser traffic crosses 1,000 monthly users and the meter starts.
• You need more than five service connections.
• You realise you are administering a delivery platform to get one if statement.

A meter is not worse than a flat price. It is worse when your usage is large and your need is small. Client-side MAU counts the people your browser SDK sees, so a marketing site or a consumer app accumulates them whether or not a flag is doing anything interesting.

Ten thousand monthly browser users is $83.30 a month at Foundation's rate, before service connections. If those ten thousand exist so that one kill switch can be flipped twice a year, you are paying for traffic rather than for value.

The reverse holds just as firmly. If you are running experiments across those same users and reading significance tests off them, that is what the platform is for, and the meter is fair.

LaunchFlag is priced the other way: Pro at $12 a month, Launch at $29, flat, per account. No per-seat charge, no client-side MAU meter, no per-evaluation charge.

It can be flat because flags are evaluated inside your own process. The SDK holds the rule set and answers locally, so your traffic never reaches us and there is nothing to meter.

import { flag } from "launchflag";

if (await flag("checkout_v2", user.id)) return newCheckout(cart);
return oldCheckout(cart);

That is the entire pricing argument, and it wins in exactly one direction: predictable and small. It loses the moment you need something off the platform list.

• You need experimentation with significance testing, not just traffic splitting.
• You need approvals before a production flag changes, scheduled changes, custom roles or SCIM.
• You want automatic rollback driven by guardrail metrics.
• Your flags are wired to segments built from user attributes LaunchDarkly stores. That data does not travel.
• You are on the free Developer tier, under 1K client-side MAU, and nothing hurts. Change nothing.

• What you wanted was a switch, and the flags you care about are kill switches and dark launches.
• You want one number on the bill that does not move when traffic does.
• You want setup to be one command and one if statement.
• You want to flip production from your phone at 2am without opening a platform.
• You ship fast, often with a coding agent, and want the last change to be reversible without a deploy.

If that is you, the free plan is one person and one project, forever, with no card.

A boolean flag ports in one edit. Keep the key name, swap the import and the call, and the branch in your code does not change at all.

What does not port is anything depending on data LaunchDarkly holds: experiments, segments built from stored user attributes, prerequisite flags, approval workflows. Move the kill switches first, because those are the flags that need to be fast and do not need a metric. Leave the platform features where they are, and expect to run both for a while if you genuinely use both kinds.

LaunchDarkly pricing, launchdarkly.com/pricing, checked 8 September 2026. Every LaunchDarkly figure and the seat quote above come from that page. Usage pricing changes without notice, so treat these as of that date and check the source before relying on them.

LaunchFlag prices and limits are on our own pricing page, and the SDK behaviour described here is in the docs. The install command is npx launchflag@latest init, and https://launchflag.dev is the base URL the SDK talks to.
