Flagsmith lets you manage features across web, mobile and server side applications. Flagsmith is Open Source. Host yourself or let us take care of the hosting.

The application consist of 3 components:

1. Server-Side REST API.
2. Front End Administration Web Interface.
3. Client Libraries.

To get up and running, you can either use https://flagsmith.com/ for 1 and 2 above, or you can self host the API and Front End. Once you have these components up and running, you can add the client libraries to your apps and start managing your features remotely.

Open Source vs SaaS vs Enterprise

You are free to run the Open Source version of Flagsmith however you see fit! There are some differences between the Open Source, SaaS hosted and Enterprise plans:

• The Open Source version has no API request or Identity limits - you can run as many API instances in a cluster as you wish
• The Open Source version has no Dashboard User limits - you can have as many team members as you wish
• The SaaS and Enterprise versions have Change Requests and Flag Scheduling
• The SaaS and Enterprise versions have Role-Based Access Controls
• The SaaS and Enterprise versions have additional Authentication Providers
