What is Flagon
Flagon is a self-hostable developer platform. Instead of stitching together a separate vendor for every capability, each with its own login, billing, and model of your world, Flagon puts the products you'd otherwise buy or build on one foundation: one organization, one login, one set of environments and teams.
The Catalog is the centerpiece the platform is built around: a live map of your services, their owners, and the products attached to them. Feature Flags is available on the foundation today, with more products shipping shortly. Because they share the platform, a concept you learn once, like an environment or a team role, carries across everything you add.
The foundation
Every product is built on the same handful of primitives. Learn these and you understand how the whole platform fits together.
An organization is your workspace: its members, their roles, and the billing boundary. People you invite become members with a role.
Will group the work for one system or team, so a large organization isn't one flat list of every resource. Not available yet: flags are org-global today.
Production, Preview, and Development keep your stages separate. Configuration is set per environment, so nothing leaks between them.
Sign in to the console, and authenticate automation with access tokens. Products issue their own scoped credentials, like SDK keys for evaluation.
One REST API under /v1, organization-scoped, documented with OpenAPI.
Everything the console does, you can script.
The centerpiece the platform is built around, bringing services, ownership, and products together. Coming soon.
Principles
Three commitments shape how Flagon is built, and they're worth knowing because they show up everywhere in these docs.
- Standards, not lock-in. Where an open standard exists, Flagon speaks it. Feature-flag evaluation is OpenFeature over its remote protocol (OFREP), so you use standard SDKs and could point them elsewhere. You're never trapped.
- Usage, never seats. Pricing is about what you use, not how many teammates you add, so inviting your whole team is free.
- Always self-hostable. Flagon is source-available and runs entirely on your own infrastructure. See Run Flagon.
