// Features
Built for teams that ship
Everything you need to monitor, debug, and recover — from a unified dashboard or your terminal.
Monitoring
See everything, miss nothing
Unified visibility into every webhook, cron execution, and MCP tool call. One dashboard, zero blind spots.
Unified dashboard
Webhooks, cron jobs, and MCP calls in one place. See everything at a glance.
Smart alerts
Slack, Discord, PagerDuty, email. Get notified where you work with actionable context.
Full history
Every run logged with duration, exit code, and output. Debug issues from last week or last month.
Real-time events
Live WebSocket feed of every webhook and cron execution. Watch events flow in as they happen.
Reliability
Never lose a request
Automatic retries, smart buffering, and guaranteed delivery. Your infrastructure's safety net.
Auto-retry
Failed delivery? Automatic retries with exponential backoff. Only alert after all retries fail.
Request buffering
Transparent proxy buffers webhooks when your services go down. Zero lost events, automatic replay.
Uptime guarantee
Dedicated webhook endpoints that never go offline. We receive it, we deliver it. Period.
Scheduled execution
Human-readable cron schedules with timeout protection. Your jobs run on time, every time.
Developer Experience
Terminal-first, cloud-optional
A CLI that works offline, config files that make sense, and a TUI for when you want to see it all at a glance.
Local-first CLI
Works 100% offline. Cloud sync is optional. Your jobs keep running no matter what.
Human-readable syntax
Write "every day at 2am" instead of "0 2 * * *". Your future self will thank you.
MCP observability
Monitor AI agent tool calls. Full request/response logging, latency tracking, and error alerts.
Config as code
Define cron jobs in YAML, manage endpoints from the CLI, and version-control your monitoring setup alongside your app.
