WunderGraph Cosmo vs Grafbase
SEPT 2026 auditA comparison of WunderGraph Cosmo and Grafbase built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
Choose WunderGraph Cosmo if…
Teams who would rather buy a ceiling than a meter: $499 a month covers two federated graphs and 250 million requests, with the router self-hosted and nothing counted per query.
Editorial · Palash Bagchi · approved
Choose Grafbase if…
Running the whole platform yourself. The gateway is open source under what Grafbase describes as no feature gating, it is written in Rust, and the enterprise tier is explicitly fully self-hostable rather than a managed service you rent.

Consider something else if…
- WunderGraph Cosmo: You run one small graph, or you need SSO and RBAC. The free tier stops at 10 million requests a month and one graph, and both SSO and RBAC first appear on Scale at $3,499 a month — seven times the entry price.
- Grafbase: You need to know the cost before talking to anyone. Grafbase publishes the open-source edition and an Enterprise tier marked Custom pricing, with no figure between them — its 99.99% SLA, 24/7 support and Slack channel all sit behind Contact Sales.

At a glance.
| Criterion | WunderGraph Cosmo | Grafbase |
|---|---|---|
| Pricing | ||
| Free tier | Yes | Yes |
| What the free plan includes | One federated graph and up to 10 million requests a month, with the self-hosted router and Discord community support. Free forever rather than a trial. | The full Rust gateway under an open-source licence, with what Grafbase calls no feature gating, and community support. A 60-day trial of the commercial platform is offered separately, with no card required. |
| Entry paid plan | $499/month for Launch: two federated graphs, up to 250 million requests a month and email support. Scale is $3,499/month for five graphs and up to 1 billion requests. | Not published. The pricing page offers the free open-source edition or an Enterprise tier marked Custom pricing with a Contact Sales button, and names no figure between the two. |
| Pricing model | Flat monthly plans bounded by two things at once: how many federated graphs you run, and how many requests a month they serve. Both ceilings rise together tier by tier. | Two options and no ladder: run the open-source gateway for nothing, or contact sales for an enterprise contract. The page's own headline says pricing scales with usage, but no rate is given. |
