SkyTap

SkyTap stands in front of every request leaving a Linux server. It runs in one of four modes: it observes, intercepts, mocks or rewrites. It is the tool we run on our own servers.

How a job runs

  1. First, the brief is written down.

    What you need, what it costs and when it ships, on paper, before anyone starts.

  2. Then you see it every week.

    Progress is shown weekly. A change of scope is priced, not absorbed.

  3. Next it goes live.

    We deploy it, hand over the keys and stay for the first weeks.

  4. After that, Care.

    A monthly retainer: uptime monitoring with alerts, daily backups, a reply within one working day.
