7 monitoring types. One platform.

APIs change without warning. Your app breaks in production.
A field gets removed. A type changes from number to string. A status code shifts from 200 to 403. Traditional uptime monitors say everything is fine.
Rumbliq catches it instantly.
Real-time schema diffing against a known baseline. Every field, every type, every status code — monitored continuously.
Know the moment your APIs go down — not when your customers tell you.
HTTP/HTTPS checks as fast as every 5 seconds (Enterprise). Track response times, status codes, and availability with historical graphs.

Frequently Asked Questions
- What is API schema drift?
- API schema drift occurs when a third-party or internal API changes its response structure without notice — fields get removed, types change, new required fields appear. These silent changes break your integrations and are invisible to traditional uptime monitors.
- How does Rumbliq detect API schema drift?
- Rumbliq sends real HTTP requests to your monitored endpoints on a schedule, captures the full JSON response, and diffs it against your established baseline. Any field additions, removals, or type changes trigger an instant alert with a full before/after diff.
- Does Rumbliq replace my uptime monitoring tool?
- Yes. Rumbliq combines API schema drift detection with HTTP uptime monitoring, SSL certificate expiry alerts, DNS record change detection, cron job / heartbeat monitoring, and public status pages — all in one platform.
- How is Rumbliq different from UptimeRobot or Pingdom?
- UptimeRobot and Pingdom only check whether an endpoint returns a 2xx status code. Rumbliq additionally inspects the response body and alerts you when the schema changes — even if the endpoint stays "up".
- What APIs can I monitor with Rumbliq?
- Any HTTP/HTTPS JSON API endpoint — public or private. Popular use cases include monitoring Stripe, GitHub, Twilio, AWS, Slack, Shopify, and OpenAI APIs for breaking changes.
- What are Sequences?
- Sequences are multi-step API workflows — you chain HTTP requests together, extract values from responses (like auth tokens), and use them in subsequent steps. Each step can assert on status codes, response bodies, and schema shape.
- Is there a free plan?
- Yes. The free plan includes 25 monitors and 3 sequences with all monitoring types (uptime, schema drift, SSL, DNS, heartbeat) and no credit card required.
