Pricing
Purple8 Graph is available across six tiers — from a free desktop app to a fully managed enterprise cluster. Each tier is a meaningful step up in scale, capability, and deployment model.
Tier overview
| Tier | Deployment | Who it's for | Price |
|---|---|---|---|
| Desktop Free | Local macOS / Windows app | Developers, experimenters | Free forever |
| Desktop Pro | Local macOS / Windows app | Power users, consultants | $49 / mo |
| Pro Cloud | Managed cloud (shared) | Startups, small teams | $199 / mo |
| Cloud Plus | Managed cloud (dedicated) | Scale-ups, production SaaS | $499 / mo |
| Self-Hosted Server | Your infra (any cloud or bare metal) | Engineering teams, ISVs | $799 / mo |
| Server Enterprise | Internal cloud, on-prem, VPC | Enterprise, regulated industries | Custom |
Pricing reflects the jump in capability. Desktop tiers are local and single-user. Cloud tiers add managed infrastructure, SLAs, and multi-tenant access. Self-Hosted Server unlocks unlimited scale, Raft HA, and the full analytics engine — deployed on your own infrastructure. Enterprise adds sharding, federation, RBAC, SSO, and compliance packs.

Overage pricing
Desktop tiers enforce hard caps — no overage is possible. Cloud tiers can burst beyond their included limits; overage is billed monthly in arrears.
| Tier | Extra nodes | Extra queries | Extra storage |
|---|---|---|---|
| Desktop Free | Hard cap — upgrade required | N/A | N/A |
| Desktop Pro | Hard cap — upgrade required | N/A | N/A |
| Pro Cloud | $10 / 1M nodes | $5 / 100K queries | $0.25 / GB |
| Cloud Plus | $7 / 1M nodes | $3 / 100K queries | $0.18 / GB |
| Self-Hosted Server | Not metered (hardware-bound) | Not metered | Not metered |
| Enterprise | Negotiated in contract | Negotiated | Negotiated |
Overage alerts
Pro Cloud and Cloud Plus subscriptions include configurable usage alerts via email and webhook. Set a threshold at 80% of your node or query limit to avoid surprise charges.
