OPERATIONS DASHBOARD
Not just an API. A full operations dashboard.
Your backend schedules the job. Your team gets a visual record of every delivery, retry, response, and failure.
Live job queue
See pending, processing, retrying, delivered, failed, and cancelled jobs in one place.
Attempt timeline
Inspect every delivery attempt with status code, latency, error, response body, and retry context.
Payload and headers
Verify exactly what was sent without searching through application logs.
Recovery controls
Cancel pending jobs, run failed jobs again, and recover deliveries from the dashboard.
Endpoint visibility
Spot failing endpoints, slow responses, and repeated delivery problems.
API-first workflow
Create jobs from your backend with one request, then operate them visually.
How it works
One API request becomes a traceable delivery.
Schedule once, then follow the full operational lifecycle from queueing to delivery, retries, and response inspection.

Talk to us ->Scheduling & execution
Jobs fire within seconds of the scheduled time. We use distributed infrastructure with sub-minute precision, not cron-based rounding.
The delivery is retried automatically with exponential backoff. Free includes 1 automatic recovery attempt, Pro includes 8, and Scale includes 12. Every attempt is logged with its HTTP status, latency, error, and response body when available.
You can cancel any pending job via the API or dashboard before it fires. Jobs cannot be modified after creation; cancel and recreate if you need to change the payload or timing.
Reliability & logs
The job is marked as failed and the full delivery history remains visible in your dashboard: every attempt, status code, latency, error, and response body when available.
Logs include the scheduled job metadata, each delivery attempt, HTTP response codes, latency, errors, and response bodies when available. Plan-specific retention automation is not advertised until it is fully wired to production cleanup jobs.
All plans run on the same production delivery path. A formal SLA is only available through a separate written agreement, so the public plans do not promise an automatic contractual SLA.
Plans & limits
One scheduled HTTP request equals one job, regardless of retries. If a job fails and retries several times, it still counts as one job against your monthly limit.
Yes. The Free plan requires no payment method. You get 100 jobs/month, 1 active API key, delivery logs, dashboard scheduling, a 7-day scheduling window, and a recent 10-job analytics window, enough to integrate and test end-to-end before upgrading.
Yes. Upgrades take effect immediately and are prorated. Downgrades apply at the start of the next billing cycle. No contracts, cancel anytime.
