spike.dev ships as an MCP server. Your coding agent can list, read and write records in any of the ten APIs while it writes the integration.

04 / FAQ

Questions

Is this the real HubSpot (or Stripe, or Salesforce)?

No. It is a compatible copy we host. It follows the public API: same paths, parameters and response shapes. It does not connect to any real account, and we are not affiliated with these companies.

Where does the data come from?

It is synthetic. We generate realistic records with linked objects, history and edge cases. Your workspace resets to a clean state every night, so you can write and delete freely.

When can I use it?

The first APIs go live within weeks of enough signups. We build them in the order people ask for them, and we email you the day yours is ready.

What does it cost?

Nothing during the beta. Later around $19 a month, and beta users get 3 months free.
