From seed to symphony: Svivva turns plain-language intent into shipped product — with validation, evaluations, versioning, and rollback so quality does not drift.

How long does it take to ship with Svivva?

Most teams get a working, tested endpoint live quickly. Describe what you need, define the output schema, deploy — Svivva handles validation, rollback, and ops.

Does Svivva work with OpenAI and other AI models?

Yes. Svivva supports OpenAI (GPT-4o, GPT-4, GPT-3.5), Anthropic Claude, Google Gemini, and other LLMs. You can route between models automatically based on cost or quality thresholds.

Do I need to write code to use Svivva?

No. Svivva's core workflow is entirely no-code — describe your API in plain English, set your output schema, and deploy. A TypeScript SDK is available for developers who want programmatic access.

Is Svivva free to start?

Yes. Svivva has a free tier with no credit card required. Paid plans start at $49/month and unlock unlimited endpoints, higher request volumes, and team features.

What happens if my endpoint returns bad data?

Svivva validates every response against your JSON schema and automatically retries or repairs malformed outputs. If quality drops below your threshold, auto-rollback reverts to the last good version.
