Everything you need for secrets management

A complete platform, not just a key-value store.

KV Secrets

Versioned key-value store with TTL, metadata, and automatic rotation policies.

Dynamic Credentials

Generate short-lived database and cloud credentials on demand. Auto-revoke on expiry.

SSO Authentication

OIDC, SAML 2.0, and LDAP. Authenticate users via Okta, Azure AD, Google, and more.

RBAC

Fine-grained role-based access control. Policies, groups, and service accounts.

Audit Trail

Append-only, tamper-evident audit log. Every access, every change, every rotation.

TLS Everywhere

mTLS between nodes, auto-provisioned certificates, encrypted client connections.

Plugin System

12 official plugins. Write your own in 50 lines of Go. gRPC-based, hot-reloadable.

Secret Injection

Inject secrets into env vars, files, or Kubernetes pods. Zero code changes.

Declarative Config

Define policies, roles, and secrets as YAML. GitOps-native. Version everything.

Diagnostics

Built-in health checks, metrics endpoint, and arcan doctor for troubleshooting.

Encrypted at Rest

AES-256-GCM encryption. Seal/unseal workflow. Supports external KMS backends.

Multi-node

Raft consensus for HA. Automatic leader election, data replication, and failover.

PostgreSQL
MySQL
MongoDB
Redis
AWS
Azure
GCP
SSH
Kubernetes
RabbitMQ

LDAP

Active Directory, OpenLDAP, FreeIPA

Write a plugin in 50 lines of Go

The plugin SDK handles lifecycle, health checks, and gRPC transport. You write the logic.

plugin_redis.go
package main import ( "context" "github.com/redis/go-redis/v9" sdk "getarcan.dev/arcan/sdk/plugin" ) type RedisPlugin struct { client *redis.Client } func (p *RedisPlugin) GenerateCredentials(ctx context.Context, req *sdk.Request) (*sdk.Credentials, error) { // Create a short-lived Redis user with ACL rules username := sdk.RandomID("arcan-") password := sdk.RandomPassword(32) p.client.Do(ctx, "ACL", "SETUSER", username, "on", ">"+password, "~*", "+@all") return &sdk.Credentials{ Username: username, Password: password, TTL: req.TTL, }, nil } func main() { sdk.Serve(&RedisPlugin{ client: redis.NewClient(&redis.Options{Addr: "localhost:6379"}), }) }

Built for operators

Single binary. No JVM, no Node.js, no Python runtime. Just copy and run.

Single Binary

One binary, all platforms. Linux, macOS, Windows. amd64 and arm64. Under 30MB.

Zero Dependencies

Embedded SQLite for single-node. PostgreSQL optional for HA. No Redis, no Consul, no etcd.

Twelve-Factor Native

Configure via env vars, flags, or YAML. Runs in Docker, Kubernetes, systemd, or bare metal.

Built on Platform

Powered by opsplanetools/platform — 13 shared packages for config, crypto, logging, health, and more.
