1Deploy Kaiten

terminal

git clone https://github.com/kaiten-hq/kaiten.git
cd kaiten
docker compose --profile full up -d

# Console:    http://localhost:5173
# API:        http://localhost/api
# API docs:   http://localhost/api/docs

git clone https://github.com/kaiten-hq/kaiten.git
cd kaiten
docker compose --profile full up -d

# Console:    http://localhost:5173
# API:        http://localhost/api
# API docs:   http://localhost/api/docs

2Create your first resources

curl

# Create a customer
curl -X POST http://localhost/api/customers \
  -H "Authorization: Bearer $TOKEN" \
  -d '{ "name": "Acme Corp", "slug": "acme-corp" }'

# Create an entitlement
curl -X POST http://localhost/api/entitlements \
  -d '{ "name": "Advanced Analytics", "type": "BOOLEAN" }'

# Create a license & bind entitlement
curl -X POST http://localhost/api/licenses \
  -d '{ "name": "Enterprise", "type": "PAID" }'

# Create a customer
curl -X POST http://localhost/api/customers \
  -H "Authorization: Bearer $TOKEN" \
  -d '{ "name": "Acme Corp", "slug": "acme-corp" }'

# Create an entitlement
curl -X POST http://localhost/api/entitlements \
  -d '{ "name": "Advanced Analytics", "type": "BOOLEAN" }'

# Create a license & bind entitlement
curl -X POST http://localhost/api/licenses \
  -d '{ "name": "Enterprise", "type": "PAID" }'

3Evaluate a feature flag (OpenFeature)

provider := ofrep.NewProvider("http://localhost/api",
  ofrep.WithHeaders(map[string]string{
    "Authorization": "Bearer ksh_your_api_token",
  }))
openfeature.SetProvider(provider)
client := openfeature.NewClient("my-service")

enabled, _ := client.BooleanValue(ctx,
  "advanced-analytics", false, openfeature.EvaluationContext{})

provider := ofrep.NewProvider("http://localhost/api",
  ofrep.WithHeaders(map[string]string{
    "Authorization": "Bearer ksh_your_api_token",
  }))
openfeature.SetProvider(provider)
client := openfeature.NewClient("my-service")

enabled, _ := client.BooleanValue(ctx,
  "advanced-analytics", false, openfeature.EvaluationContext{})

Three APIs. One control plane.

REST API

Bearer token auth · ksh_* tokens

Full CRUD on all resources. Auto-generated OpenAPI spec served via Scalar at /api/docs.

GraphQL API

Endpoint: /api/graphql

Complex queries joining multiple entities. Batch queries for Console data fetching.

OFREP

Endpoint: /api/ofrep/v1/evaluate

OpenFeature Remote Evaluation Protocol. Standard feature flag evaluation from any OpenFeature SDK.

Type-safe clients. Generated from the spec.

Always in sync with the API. Full type safety. Every endpoint covered.
