Built in Breda, run as a developer tool. The working surface is an MCP server your agent connects to — the web app is the smaller half.
Viralz scrapes and analyses LinkedIn content — creators, posts, audiences, engagement — and turns the result into research an agent can query and act on. The analysis runs server-side on a schedule; you read it through tools, not through a report you have to open.
The primary way in is MCP. One connection exposes every tool we ship. That is the surface we support and the surface we test.
One line in a terminal. The same command is on the skills page and in the console.

There is no viralz CLI, and none is planned as a separate binary. An MCP client is how you drive Viralz from a terminal.
The REST API authenticates a signed-in browser session. Programmatic keys exist in code but are switched off on the deployed backend, so there is nothing to issue you today.
There is no free plan and no signup credit grant. Plans are EUR 30, EUR 149 and EUR 499 per month, and only the first is live.
Create an account, pick a plan, pay with Stripe. The beta-code program is retired — no code and no waitlist between a card and a subscription.
Viralz is built by Jasper Ruijs and owned by Grow Steady, Breda, Netherlands. It is a small operation: the person who answers your email is the person who wrote the tool you are asking about.
It is in beta, and the pages on this site say which parts are live and which are not. If you find a page claiming something the product does not do, that is a bug — tell us.
