Frequently Asked Questions

Everything you need to know about Onagre.

General

What is Onagre?

Onagre is a monitoring platform that tells your team when your applications, websites, APIs, scheduled jobs or business processes stop working — before your users or customers report the issue. No infrastructure expertise required.

What can I monitor with Onagre?

Websites, APIs, scheduled jobs, databases, internal applications, end-to-end business processes and SSL certificates — all from a single, easy-to-use platform.

Is Onagre free to use?

Yes! Our Free plan lets you monitor up to 10 things at no cost, with regular checks and essential alerts. No credit card required. You can upgrade anytime to monitor more and unlock advanced features.

What you can monitor

How often does Onagre check?

On the Free plan, checks run every few minutes. On paid plans, checks can run as often as every minute. Each thing you monitor can have its own frequency.

Can Onagre check more than just "is it online"?

Absolutely. Beyond availability, Onagre checks response times, whether the right content or data is returned, whether a scheduled job actually ran, and whether certificates are about to expire.

Internal & private apps

Can I monitor applications inside my own network?

Yes. Onagre can watch your public websites and APIs out of the box, and it can also monitor private, internal applications that aren't exposed to the internet.

How does Onagre reach my internal systems?

You install a lightweight, secure connector inside your network in just a couple of minutes. It lets Onagre monitor your internal systems without opening your network to the outside — no inbound access required.

Security

Where is my data stored?

All data is hosted in France on European infrastructure. We are GDPR compliant and use AES-256 encryption for data at rest and TLS for data in transit.

How are credentials and secrets secured?

Sensitive data such as access keys, database passwords and authentication details are stored encrypted. They are only used at the moment of a check, and are never logged or exposed.

Billing

Can I upgrade or downgrade my plan?

Yes. You can upgrade at any time and changes take effect immediately with prorated billing. Downgrades are applied at the end of your current billing period.

Is there a free trial?

Our Free plan is free forever, letting you monitor up to 10 things. For paid plans, we don't offer a traditional trial, but you can explore the full platform on the Free plan before upgrading. Contact us if you'd like to test a specific paid feature.
