What you get with WunderGraph Federation
Federation without the things that slow you down at scale.
WunderGraph Federation makes four commitments the closed-source alternatives can't match.
Open source, always
Own your own infrastructure. Cosmo is Apache 2.0 — fork it, self-host it, or run it on our managed cloud. Your call.
Pricing that scales with you, not against you
Pay for what you use. No tiers that double the bill. Add traffic and add teams without renegotiating.
Start in minutes, not months
Point your existing subgraphs at our router and go. No schema rewrites. No code changes. Full Apollo Federation v1 and v2 compatibility.
Govern with confidence
Ship fast without breaking the graph. Schema ownership, breaking-change detection, proposal workflows, and RBAC are built in - not priced as add-ons.
Migration path
What switching actually looks like
Run both platforms side by side. Check that the numbers match. Flip the switch when you're ready.
Point your subgraphs at our router
Drop-in replacement. Full Federation v1 and v2 compatibility. Your subgraph code doesn't change.
Import your schema registry

Zero downtime. Full observability on day one. The bill drops the moment you switch.
