Billing Model
Overview
RushDB uses a Knowledge Units (KU) billing model. You pay for the structured knowledge RushDB creates and maintains from your data — not for infrastructure, nodes, edges, storage, or compute.
Total KU consumed in billing period × price per KU = your bill
This model aligns cost with value: you pay more only when RushDB is doing more work to organize and serve your data.
Monthly Billing Cycle
KU consumption resets at the start of each billing period. Your plan includes a base KU allowance. Consumption above the included allowance is billed as overage (Pro and above).
Bill = included KU (flat rate) + overage KU × overage rate

One Metric
KU is the only number that matters for billing. RAM, CPU, storage, node counts, edge counts, and query time are infrastructure concerns — RushDB absorbs them. Your bill reflects the knowledge work done, nothing else.
Soft and Hard Limits
- Soft limit: RushDB sends an alert when you reach 80% of your monthly KU allowance.
- Hard limit: Write operations are blocked when your allowance is exhausted. Read operations continue unaffected.
- You can configure alerts and caps from the KU Usage page in your dashboard.
Self-Hosted Billing
Self-hosted deployments (RUSHDB_SELF_HOSTED=true) have no KU limits and no billing. The OSS engine runs entirely without quota enforcement.
For teams that need the full platform (dashboard, projects, API key management, team members) without usage caps, contact us about an Enterprise platform license.
Changes to Limits Mid-Period
- Upgrading your plan: new KU limit takes effect immediately.
- Downgrading your plan: new KU limit takes effect at the start of the next billing period.
- Cancelling: your current allowance remains active until the end of the paid period.
KU Usage Dashboard
Your KU consumption is visible in real-time on the KU Usage page in your workspace dashboard:
- Total KU consumed this month
- Remaining KU
- Estimated end-of-month cost
- Daily consumption trend chart
- Ingestion and query spike timeline
