# Feature Matrix — Stella Ops Suite
*(rev 5.1 · 16 Jan 2026)*

> **Looking for a quick read?** Check [`key-features.md`](key-features.md) for the short capability cards; this matrix keeps full tier-by-tier detail.

## Product Evolution

**Stella Ops Suite** is now a centralized, auditable release control plane for non-Kubernetes container estates. The platform combines release orchestration with security decisioning as a gate.

- **Release orchestration** — UI-driven promotion (Dev → Stage → Prod), approvals, policy gates, rollbacks
- **Security decisioning as a gate** — Scan on build, evaluate on release, re-evaluate on CVE updates
- **OCI-digest-first releases** — Immutable digest-based release identity
- **Evidence packets** — Every release decision is cryptographically signed and stored

---

## Pricing Model

**Principle:** Pay for scale, not for features or automation. No per-seat, per-project, or per-deployment taxes.

| Plan | Price | Environments | New Digests/Day | Deployments | Notes |
|------|-------|--------------|-----------------|-------------|-------|
| **Free** | $0/month | 3 | 333 | Unlimited (fair use) | Full features |
| **Pro** | $699/month | 33 | 3,333 | Unlimited (fair use) | Same features |
| **Enterprise** | $1,999/month | Unlimited | Unlimited | Unlimited | Fair use on mirroring/audit bandwidth |

**Key Principles:**
- All plans include all features (no feature gating)
- Limits are environments + new digests analyzed per day
- Unlimited deployments with fair use policy
