Build the backend free. Deploy your server with Runtime.
The Dev tier covers the BaaS: auth, data, live ops, matchmaking, and SDKs within its documented limits. Runtime is a separate capacity-gated closed alpha: admitted Dev projects receive a small evaluation allowance; ongoing access is separate from BaaS pricing.

Crux Runtime
Godot 4 Linux export → isolated EU process → READY endpoint → short-lived join tickets → logs/results → clean termination. No Docker is required from the developer.
Runtime is currently capacity-gated. Admitted Dev projects receive three lifetime evaluation hours, one concurrent session, and a one-hour session cap. It is not an unlimited free-compute tier. Read the v0 contract →

Verify the product before you pay for it.
The Dev tier does not require a card. Run the API, inspect the contract and client source, and confirm the exit path before upgrading. Pricing should be the last unknown, not the first leap of faith.
Live API status
A live check of the hosted API right now. No made-up uptime percentage and no hidden demo environment.
Check current statusPublic API contract
The hosted HTTP surface is documented as OpenAPI. Inspect the wire format before choosing an SDK or writing an adapter.

The JavaScript, Godot, Unity, and Roblox client SDK source is public. The hosted backend itself remains a managed proprietary service.

Model MAU, peak CCU, regions, and feature mix without pretending those inputs determine every competitor's bill.
Model the workloadWhat counts as a MAU?
Any player who authenticates (guest, email, OAuth, or custom token) at least once in a calendar month. Bots and server tokens are free.
What happens over the limit?
Nothing is cut off automatically. Every plan has a peak request rate (10 / 100 / 1,000 req/s) and requests beyond it get a 429 with Retry-After - your game keeps working, just throttled. Monthly allowances are not hard-metered; if sustained usage outgrows your tier we email you about upgrading. There is no per-call billing, so there are no surprise invoices.
Can I downgrade?
Yes - anytime. Your data stays put; only the limits change.
Is Runtime free forever?
No. The BaaS Dev plan is live and free within its MAU/API limits. Runtime is currently a capacity-gated closed alpha; admitted Dev projects receive three lifetime evaluation hours. Ongoing Runtime access is separate from the BaaS tier.
Do you have a startup deal?
Yes. Use the Custom / startup form with a one-liner about your game and we’ll sort it out. Email remains available there as a fallback.
