Teams of all sizes depend on Odown to keep mission critical APIs fast, predictable, and available.

API monitoring

Do not gamble with your API uptime

Your product runs on APIs. A brief outage, a creeping latency spike, or a silent contract failure can break checkouts and dashboards, and frustrate users. We watch your endpoints continuously, alert you the instant something looks wrong, and help you fix issues before customers notice.

With Odown, your API is checked on a schedule you control, so you can respond quickly and protect revenue when incidents happen.

Endpoint request method

Custom HTTP request

Build each request to match your API. Choose method, URL, query, headers, and body. Add authentication with API keys or tokens, include cookies if needed, and test the exact call your clients make in production.

Rich data

Everything you need, visualized

Track uptime and response time with clear charts. Break down performance into DNS, TCP, TLS, and time to first byte, then pinpoint where slowdowns begin and where to fix them.

Unlimited notifications

Alerting for any situation

Route alerts to the tools your team already uses. Send to Slack, PagerDuty, Opsgenie, Discord, Telegram, email, or SMS, and use webhooks when you want to trigger your own automations. Configure who gets what, apply quiet hours and escalation rules, and keep everyone aligned.
