COSTNERVE INTEGRATION
Fly.io cost intelligence: coverage, cost model and roadmap.
The useful question is not only what Fly.io costs, but which workload created the change, whether the trend will persist and what the spend means for customer or product margin. CostNerve is designed around that chain of evidence.

Cost dimensions to understand
- organization
- app
- machine
- region
- volume
- egress
Where cost usually escapes control
always-on machines
Compare the Fly.io change with the previous baseline, deployment history and workload volume. Attribute economic impact before proposing a reversible action.
regional duplication
Compare the Fly.io change with the previous baseline, deployment history and workload volume. Attribute economic impact before proposing a reversible action.
volume growth
Measure growth, retention and access frequency in Fly.io. Separate active data from stale data before estimating deletion, tiering or retention-policy savings.
egress growth
Break Fly.io transfer cost down by source, destination and workload, then compare the change with traffic and deployment history before recommending a fix.
Turn provider spend into unit economics
- cost per app
- cost per customer
- cost per request
- cost per region
What to check in the provider dashboard
- Open the Fly.io usage and billing dashboard; this guide does not imply live CostNerve ingestion.
- Compare organization, app, machine over equal, complete periods.
- Keep usage, estimates and invoice amounts separate. Record the scope, currency and last update.
- Check integration coverage before connecting; use available connectors for supported evidence.
