Company
One platform, one account, one key, one bill.
Sylphx Limited builds the platform this site serves, and everything on it is reached through the same account, the same key system and the same invoice.
What we are
One platform, one account, one key, one bill.
Sylphx is one platform for hosting, Postgres, auth, AI and sandboxes: one account, one API key, one SDK, and one bill. Start free, no card.
Each service is usable on its own — start from Data, Auth or AI without adopting anything else. What they share is the part you should not have to rebuild: one account and organization, one key system, one SDK, one CLI, one MCP server, one bill. An Access key works for every service you have enabled, and revoking it reaches every service at once.
Sylphx is not:
- A bundle you have to adopt whole. A service you have not enabled admits no calls, and disabling one stops admission without deleting its data.
- A separate signup, key, console or bill per service.
- The apps we build. They run on Sylphx as ordinary customers and carry their own brands.
- A reseller that swaps the model or the provider you asked for.

The products index lists each one with its status, and the products the platform does not serve yet. A product without a served surface is planned, and is not sold.

Honestly
What this page does not publish
No headcount, no office list, no named customer, no funding figure and no date. None of those are published for the company, so none of them appear here — a company page that filled those spaces would be inventing, and there is no version of that worth reading.
What is published is the working surface: the docs, the pricing page, the changelog, the security pages and live status. Those are the surfaces to decide against, and every claim on them can be checked against something you can read or call yourself.
