Flaggy vs LaunchDarkly: a feature flag comparison for teams who hate their invoice
An honest, up-to-date comparison of Flaggy and LaunchDarkly — usage-based MAU pricing vs flat $99/month, feature gates, and where each one wins.
Most teams don’t go looking for a LaunchDarkly alternative because the product is bad. They go looking because the invoice grew faster than the value did — the MAU meter kept running, the service-connection charges added up, and the renewal conversation started from a number nobody remembered agreeing to.
This is an honest, current comparison of Flaggy and LaunchDarkly. LaunchDarkly recently reworked its pricing, so the figures here reflect their published model as of mid-2026, not the old per-seat plans you may remember. (Weighing more than one option? See our roundup of the best LaunchDarkly alternatives.)
The short version
LaunchDarkly is a mature, broad experimentation platform that prices on usage — monthly active users and service connections — and reserves a lot of its governance features for the Enterprise tier. Flaggy is a focused feature flag platform with one flat price: $99/month for the Team plan, unlimited seats, no usage metering of any kind.
If you want feature flags that do their job without a bill that tracks your traffic, Flaggy is built for exactly that. If you need large-scale, statistically-rigorous experimentation with multivariate variants, LaunchDarkly does more — and the meter reflects it.
Pricing: the reason most people are reading this
This is almost always the real question, so let’s start here.
LaunchDarkly’s current plans are Developer (free), Foundation, Enterprise, and Guardian. Notably, they’ve dropped per-seat pricing — every tier now includes unlimited seats. The metering moved to usage instead:
- $8.33 per 1,000 client-side MAU / month — Monthly Active Users, counted by the contexts your client-side and edge SDKs encounter.
- $10 per service connection / month — for your server-side connections.
- Foundation is billed yearly, with custom pricing above it on Enterprise and Guardian.
Those are LaunchDarkly’s annual-commitment rates — the cheapest they publish. Month-to-month runs higher. We use the discounted figures here on purpose: even at LaunchDarkly’s best-case price, the comparison below holds.
The trap is the same one it’s always been, just relabeled: your bill tracks your usage, and usage isn’t fully under your control. The MAU count climbs every time your product succeeds. A viral week is supposed to be good news — but it also moves the meter.
Flaggy charges one number:
| Flaggy Team | LaunchDarkly Foundation | |
|---|---|---|
| Base price | $99/mo flat | Usage-based |
| MAU metering | None | $8.33 / 1,000 client-side MAU |
| Service-connection fees | None | $10 / connection |
| Seats | Unlimited | Unlimited |
| Bill grows with traffic | No | Yes |
| Predictable renewal | Yes | Depends on usage |
The seat war is over — both tools give you unlimited seats now, and that’s genuinely good for everyone. The difference that remains is the meter. At 100,000 client-side MAU, LaunchDarkly’s MAU charge alone is roughly $833/month (100 × $8.33) before service connections. Flaggy is $99 — at 100K MAU or 100M. You can run your own numbers on the pricing page, and there’s a deeper teardown in our LaunchDarkly pricing breakdown.
Why Flaggy can charge flat and LaunchDarkly meters MAU
This isn’t a generosity story — it’s an architecture story. MAU-based pricing was designed for an era when flag evaluation happened server-side: every flag check was an API call to the vendor, so charging per active user roughly tracked the vendor’s compute cost.
Modern SDKs don’t work that way. Flaggy’s SDK downloads your ruleset and evaluates flags locally, in your app’s memory — a dictionary lookup, no round trip. We never see individual evaluations, so there’s nothing to meter. Our costs scale with the rules we store and sync, not with your user count. That’s the whole reason we can hold the price flat. We wrote up the full reasoning behind flat pricing if you want it.
Feature comparison
| Feature | Flaggy | LaunchDarkly |
|---|---|---|
| Boolean flags | Yes | Yes |
| Multivariate flags | No | Yes (all tiers) |
| Percentage rollouts | Yes | Yes |
| Targeting segments | Yes | Yes |
| Experimentation / A/B | Boolean + rollout | Yes (all tiers) |
| Flag analytics | All plans | Yes |
| Audit log | Every plan | Enterprise only |
| Approval & scheduling workflows | Team plan | Enterprise only |
| Custom roles / SCIM | — | Enterprise only |
| Unlimited seats | Team plan | All tiers |
| JavaScript / TypeScript SDK | Yes | Yes |
| Self-serve signup | Yes | Yes |
The row worth dwelling on is governance. On LaunchDarkly, audit logs, approval workflows, custom roles, and SCIM are Enterprise features — which means the controls your security reviewer asks for arrive bundled with the most expensive, sales-negotiated contract. On Flaggy, audit logs are on every plan, including Free, and approval workflows come with Team. You get the accountability without buying the tier.
Where LaunchDarkly is the better choice
A comparison that only flatters one side isn’t useful, so here’s the honest part.
Flaggy is boolean-only. isEnabled() returns true or false. There are no multivariate flags or named variants. If your workflow depends on shipping four button colors or five copy variants behind a single flag key, LaunchDarkly supports that on every tier and Flaggy doesn’t.
For most teams this matters less than it sounds: the common A/B case is “does the new version beat the old one,” which is a boolean flag with a percentage rollout — half your users get it on, half get it off, and you compare a metric between the groups. But if you genuinely need many-armed variants managed in one place, that’s a real gap.
LaunchDarkly has a deeper experimentation surface and a generous free tier. Large-scale statistical experimentation and advanced experiment analysis are areas where LaunchDarkly has years of investment. Their free Developer plan is also genuinely capable — unlimited seats, unlimited flags, A/B tests — so for a small project that never grows its MAU, it’s a reasonable place to start. Flaggy is deliberately scoped to feature flag management: flags, segments, targeting, audit, analytics — not a full experimentation suite.
One honest note on flag propagation. Neither tool makes a dashboard toggle reach your users literally instantly — Flaggy’s SDK refreshes flags on a background poll (about a minute by default). The thing that’s genuinely fast is that flipping a flag is a dashboard action with no deploy. If you need sub-second push propagation as a hard requirement, evaluate that specifically rather than assuming any vendor’s marketing copy.
How to decide
Pick Flaggy if you want:
- A flat cost that doesn’t move when your traffic spikes
- Audit logs and approval workflows without an Enterprise contract
- A focused tool that does feature flags well and gets out of the way
Stick with or pick LaunchDarkly if you need:
- Multivariate flags with many named variants
- Large-scale, statistically-rigorous experimentation as a core workflow
- A wide enterprise surface bundled with the flag tool
Migrating off LaunchDarkly
For teams that decide to switch, migration is usually a day, not a quarter:
- Export your flags as JSON from the LaunchDarkly dashboard.
- Restructure them to Flaggy’s format — typically an hour or two of scripting.
- Run both SDKs in parallel during the transition: existing flags stay on LaunchDarkly, new ones go to Flaggy.
- Cut over fully once you’re confident.
The SDK swap is the same pattern as replacing any dependency. The cost is time, not complexity, and there’s no MAU clock running while you do it.
If you want the side-by-side feature grid and a cost calculator, the Flaggy vs LaunchDarkly page has both. Or just start free — no credit card, and the price you see is the price it stays.
