Open Core & Licensing

Krewire is an open-source community based in Indonesia, operating under a transparent Open Core business model.

Our licensing framework guarantees complete freedom for builders while offering advanced operational, compliance, and enterprise features through commercial tiers.

1. The Four-Rung Tier Ladder

The ecosystem organizes modules into four distinct rungs:

┌──────────────────────────────────────────────┐
│  4. Enterprise (B2B, air-gapped, custom SLA)  │
├──────────────────────────────────────────────┤
│  3. Team (Multi-tenant governance, audits)   │
├──────────────────────────────────────────────┤
│  2. Pro (Advanced telemetry, high throughput)│
├──────────────────────────────────────────────┤
│  1. Free (Core libraries, CLI, full SDLC)    │
└──────────────────────────────────────────────┘
Tier License Model Pricing Target Audience
free Permissive Open Source (MIT) $0 Forever Individual developers, startups, open-source projects.
pro Commercial Source-Available Published Self-Serve Growing teams needing hardened drivers and metrics.
team Commercial License Published Organization Mid-market companies needing SSO, RBAC, and multi-tenant policies.
enterprise Negotiated B2B Contract Custom Quote Air-gapped deployments, custom compliance, and dedicated 24/7 SLAs.

2. Inviolable Architectural Rules

As documented in internal/docs/open-core.md, three rules protect the integrity of the open-source core:

Rule 1: Zero Runtime Lock-in

A project referencing only free packages must build, deploy, and run with zero license keys or cloud call-homes. There is never a trial expiration or hidden limit on the free tier.

Rule 2: Additive Wrapper Boundaries

Paid modules may wrap, harden, or optimize a free module, but a paid module must never be a prerequisite for a free module.

Rule 3: Strict Hierarchy Subsets

Each rung is a strict superset of the rung below it:

  • pro includes all of free.
  • team includes all of pro and free.
  • enterprise is negotiated per organization and is never a published fixed price.
