Early access, free for commercial use

Know it broke before your customers do.

One timeline for your websites, cron jobs and everything that quietly expires: certificates, domains, subscriptions. Every alert says what broke, not just that it did.

Free for commercial use. We use your email only to tell you when early access opens. See our privacy policy.

Alerts that diagnose

The first ten minutes of an incident, already done.

Most tools tell you the site is down. We tell you where the request stopped: DNS, TCP, TLS, time to first byte or the response body. You open the alert and know what to fix.

Deadlines

Everything that expires, in one list.

SSL certificates and domains are tracked for you. Add the rest by hand: SAML signing certificates, Entra client secrets, subscriptions and payments that switch services off, licences. Reminders by Telegram or email, with an owner who has to act.

Names and dates only
We never ask for or store keys, passwords or secret values.
Free tools, no account

Questions

Is the free plan really free for commercial use?

Yes. Use it for your own business and for client projects. Limits come from the plan, not from what you do with it.

Where is my data stored?

In the EU, on servers in Germany. We publish a list of subprocessors and sign a DPA on request.

Do you store my secrets or keys?

No. For deadlines we store a name, a date and an owner. Fields reject anything that looks like a key or a token.
