Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Fireworks AI
- Reserved and enterprise-tier pricing is not published and requires sales contact.
- Model catalog is curated to ~30 models, smaller than DeepInfra's 100+ model library.
- On-demand GPU rates are scheduled to increase from September 1, adding cost unpredictability for locked-in workloads.
Pulumi
- The free Individual plan allows one user and one concurrent stack update
- The Team plan is $40 per month base including 40 credits, and caps the organisation at 10 users
- SAML/SSO, RBAC, audit logs and drift detection require the Enterprise plan at $400 per month base
- The per-resource rate rises from $0.1825 per resource per month on Team to $0.365 on Enterprise, so upgrading raises the unit price as well as the base fee
- Managed secrets are billed separately at $0.50 per secret per month on Team and $0.75 on Enterprise
- Self-hosting, SCIM user sync, audit log export and 24x7 support are only in Business Critical, which is custom priced with no published rate
- Team includes up to 500 resources and Enterprise up to 2,000, with everything beyond billed on demand as credits
