Automatic detection, severity levels, acknowledgment workflow, and reliability metrics (MTTR, MTBF, MTTA) built in.
Slack, Discord, Teams, Google Chat, Email, Webhooks, Pushover, Gotify, and our native Android app.
Deploy lightweight agents behind your firewall. Linux, Windows, Docker. No VPN needed, no complex setup.
Visualize how your services connect with an interactive graph. Spot cascading failures instantly.
Organize sensors by environment. Store variables and encrypted secrets (AES-GCM 256) securely.
Start monitoring your applications in under 60 seconds.
Sign up for free. No credit card, no installation required. Start monitoring public resources immediately.
Choose from 14 sensor types. Use templates for quick setup or customize every parameter to your needs.
Connect Slack, Discord, Teams, or any webhook. Onagre alerts you only when something actually breaks.
14 sensor types covering every layer of your application stack.
Verify URL availability and validate expected HTTP status codes.
Check if a specific keyword is present in HTTP response body.
Extract and validate values from JSON API responses with comparison operators.

Everything you need to know about Onagre.
Onagre is a SaaS monitoring platform focused on application-level resources. It helps you track the health of your APIs, databases, queues, certificates, and more — without the complexity of traditional infrastructure monitoring tools.
You can monitor HTTP endpoints, JSON/XML APIs, DNS records, SSL certificates, TCP ports, databases (SQL and Key-Value), message queues, file checksums, and application heartbeats. Onagre supports 14 sensor types in total.
Yes! Our Free plan includes up to 10 sensors with HTTP-based monitoring, a 5-minute check interval, and basic integrations. No credit card required. You can upgrade anytime for more sensors and advanced features.
On the Free plan, checks run every 5 minutes. On Pro and Enterprise plans, you can set the interval as low as 1 minute. Each sensor can have its own interval.
Onagre supports 14 sensor types: HTTP Response, Keyword, JSON, XML, Ping, Port, DNS, SSL Certificate, SQL, Key-Value DB, Dead Letter Queue, File Checksum, Heartbeat, and Server. Availability depends on your plan.
Public agents are managed by Onagre and check resources accessible from the internet. Private agents are lightweight executables you install in your own network to monitor internal resources behind firewalls — no VPN needed.
On Linux, run a single command: curl -fsSL https://d.onag.re/onagent.sh | sudo bash. Docker and Windows (as a service) are also supported. The agent connects to the Hub automatically via gRPC.
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.
Sensitive data such as API keys, database passwords, and authentication headers are stored encrypted. They are only decrypted at check execution time within the agent and never logged or exposed.
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.
Our Free plan is free forever with up to 10 sensors. 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.
