What Deployment Options Does Flagsmith Provide?
Flagsmith offers both self-hosted and managed deployment paths: an open-source version you can run on your own infrastructure (on-premise), a private cloud option, and a hosted cloud service. The right choice depends on how much control you need over where flag data and configuration live, and how much operational work you want to take on yourself.
The deployment options at a glance
Flagsmith describes its deployment model as "flexible deployment options," with on-premise and private cloud hosting called out as ways to "stay secure." In practice that maps to three broad choices:
| Option | Who runs it | Best fit when |
|---|---|---|
| Open source / self-hosted (on-premise) | Your team, on your own infrastructure | You need full control of the environment, want to keep flag data inside your own network, or already run your own services |
| Private cloud | Flagsmith, in an isolated environment | You want managed operations but can't use a shared multi-tenant service |
| Hosted cloud | Flagsmith | You want the fastest start and don't have infrastructure constraints |
The open-source route is the one most clearly documented on the site: the homepage presents "Start for Free" and "Explore Open Source" side by side, and the product is positioned as an open-source feature flag service. That means the self-hosted path is a first-class option rather than an afterthought.
What "on-premise" actually gets you
Self-hosting matters most for teams with data-residency, network-isolation, or procurement rules that rule out a shared SaaS endpoint. Running Flagsmith yourself means:
- Flag definitions, segment rules, and remote config values live in infrastructure you control.
- You decide the upgrade cadence and can pin a version.
- You own backups, availability, and scaling.
The trade-off is the mirror image: you also own the operational work. If nobody on the team wants to run and monitor another service, the hosted option removes that burden.
How this connects to what Flagsmith does
Deployment choice isn't separate from the product's core behavior — it determines where that behavior runs. Flagsmith's feature flags work across web, mobile, and server-side applications, and the same flags can carry remote config values so you can change functional or visual behavior without a code deploy or app store approval. Segmentation rules let you target individual users, user segments, or a percentage of users, which is what makes canary deployments and A/B or multivariate tests practical.
The homepage example shows the client-side shape of this:
import flagsmith from 'flagsmith';
flagsmith.init({
environmentID: 'QjgYur4LQTwe5HpvbvhpzK',
});
const App = () => (
<Layout
darkMode={flagsmith.hasFeature("dark_mode")}
designV2={flagsmith.hasFeature("design_v2")}>
{flagsmith.hasFeature("chat") && <ChatWidget />}
</Layout>
);
Where that environmentID points — your own instance or a hosted one — is exactly what the deployment decision controls.
Choosing between them
- Pick self-hosted / on-premise if flag data can't leave your network, you have compliance or residency requirements, or you want to avoid a third-party dependency in your release path and have the capacity to run it.
- Pick private cloud if you need isolation but not the operational overhead of running the service yourself.
- Pick hosted cloud if speed of setup matters more than infrastructure control and there's no rule against an external service.
One caveat worth stating plainly: the site confirms these options exist and points to a pricing page, but it doesn't publish the specific resource requirements, supported deployment targets, or plan-level feature differences in the material available here. Before committing, check the official documentation and pricing page for the current details on each option — particularly if your decision hinges on a specific hosting environment or support tier.
