All the Features - Without Vendor Lock-In
Don’t overpay for LaunchDarkly.
We guarantee you get a world-class feature flagging solution without vendor lock-in or LaunchDarkly prices.

Release with confidence; manage feature flags across web, mobile, and server-side applications.


SaaS LaunchDarkly Alternative
Get everything dev teams need out of a robust feature flagging solution and then go beyond that!
Take the advantage of the world’s best latency with our Edge API.
Your requests are automatically routed to the closest of our 8 data centers around the globe, minimizing the latency of every request you make.
We aim to serve 99% of requests within under 100ms, and in many cases, it’s much less.
Are you tired of LaunchDarkly pricing? If you’re looking at scalable and less expensive LaunchDarkly competitors - you definitely need to check Flagsmith out.
Integrations
If this sort of pricing is important to you - please get in touch. We are happy to accommodate longer agreements and work with your legal/security teams to get up and running.
Don't worry; we'll carry on serving your flags to your users. We realize that this is important to your application. If this does happen, we'll be in touch to discuss upgrading you to a new plan.
Yes! We believe that enabling engineering teams to run feature flags how they want is fundamental to a great feature management platform. You can run Flagsmith on-prem with your own infrastructure, you can use our Global Edge API and if that isn't enough, we'll even set up a private cloud infrastructure just for your team.
Our mission is to empower development teams to ship faster and continuously improve their products. That applies to the largest enterprise or a small startup; so we have features and pricing plans to meet the needs of any team.
See what features you need, or reach out and talk to us to learn more. We love helping you ship features faster and with more confidence!
Flagsmith ships with SDKs for a bunch of different programming languages. We also have a REST API that you can use if you want to consume the API directly.
Don't feel locked into a vendor or stuck with LaunchDarkly SDKs.
