Six LaunchDarkly alternatives, compared honestly

Including us, bias declared up front. Every price below was read from the vendor's own pricing page, and each entry says who should genuinely pick it.

Why people look for an alternative

LaunchDarkly is the category leader for a reason: a rich rule builder, a real experimentation suite, and enterprise compliance. Most teams that leave don’t leave because it’s bad; they leave because of how the bill grows. Foundation pricing is US$10 per service connection plus US$8.33 per thousand client-side monthly active users, so the invoice tracks your architecture and your traffic. At 10,000 MAU across six services that’s roughly US$143 a month; at 200,000 MAU it’s roughly US$1,726 a month, for feature flags. We’ve worked through the numbers in detail if you want to check them.

If that’s the problem you’re solving, the question isn’t “which tool is most like LaunchDarkly”; it’s “which meter am I trying to escape, and what am I willing to trade”. Every option below meters something different, or nothing at all. Here’s the honest map.

1. RocketFlag (that's us, bias declared)

Feature flags at one flat price. That's the product.

Price
A$79/month (about US$52) for unlimited seats, evaluations and flags
What's metered
None. The price on the page is the bill.
Choose it for
Teams that want release gating, canary rollouts and kill switches with a bill that never moves, with flag hygiene handled by Caretaker's AI-agent removal prompts.
Watch for
No experimentation suite, no self-hosting, environments cap at 7 per project. If you need those, one of the tools below is the honest pick.

2. Flagsmith

Full comparison →

Open-source flags with a metered cloud.

Price
US$45/month (Start-Up); cloud meters both requests and seats
What's metered
1M requests/month included, then US$50 per million. 3 seats, then US$50 per member on the next tier.
Choose it for
Teams that need self-hosting or an on-premise enterprise deal. Flagsmith is genuinely open source and you can run it yourself.
Watch for
The two cloud meters both point at growth: cross the request cap and hire two people in the same quarter and US$45 becomes several hundred.

3. Unleash

Full comparison →

Open-source flags with enterprise depth, priced per seat.

Price
US$75 per seat/month (Pay-As-You-Go)
What's metered
Every seat. Requests are barely metered (53M/month included), but a team of five is US$375/month.
Choose it for
Organisations that need self-hosting plus enterprise controls: SSO, RBAC, change requests, a 99.99% SLA.
Watch for
The seat meter counts everyone who touches a flag, PMs and support included. No free cloud tier.

4. ConfigCat

Full comparison →

Straightforward hosted flags with hard caps.

Price
US$110/month (Pro)
What's metered
100 flags, 3 projects, 3 environments, 25M downloads/month plus a 100GB traffic cap.
Choose it for
Teams that like rich targeting rules and a simple hosted product, comfortably inside the caps.
Watch for
The caps are real: the 100-flag limit arrives faster than teams expect, and the next tier up is a jump.

5. PostHog

Full comparison →

Flags bundled into an all-in-one product platform.

Price
Free to 1M flag requests/month, then ~US$0.0001/request, stepping down with volume
What's metered
Every flag request past the free million. ~US$235/month at 5M requests, ~US$710 at 20M.
Choose it for
Teams that want analytics, session replay, experiments and flags in one tool, or teams under a million requests a month, where it's genuinely free.
Watch for
Flags live on your hottest paths, so the flag bill tracks your traffic. The launch that triples your traffic triples this line item.

6. Featureflip

Their pricing →

Flat-price flags with seat and project caps.

Price
US$49/month (Pro)
What's metered
10 seats, 10 projects, 5 environments. Evaluation limits not published.
Choose it for
Small teams that want a cheap flat price and fit inside 10 seats.
Watch for
The flat price has edges: seat 11 means the next tier, and the evaluation policy isn't published, so ask before you commit.

RocketFlag was born out of a simple need: a better, more reliable way to manage feature flags without the complexity and cost of enterprise tools. I'm JK, the creator behind RocketFlag. When you use this service, you aren't just using a tool you're getting direct access to the person building it. Whether you have questions about implementation or want to discuss new features, I'm always happy to chat with fellow engineers. If you happen to be in Perth, the coffee is on me!
