The Philosophy of Seiri

Why Seiri?

Seiri comes from the Japanese 5S methodology of workplace organization. It means "to sort" or "to clean" — the fundamental first step toward operational excellence.

Just as a clean, organized workspace is essential for productivity, clean monitoring is essential for reliable systems. Seiri represents our commitment to bringing order to the chaos of modern infrastructure monitoring.

Our Vision

A world where system failures are caught before they impact users, where teams have complete visibility into their critical processes.

Frequently Asked Questions

How does Seiri detect failed jobs?

Seiri uses a "heartbeat" approach. Your jobs ping our unique URLs when they run successfully. If we don't receive a ping within your defined schedule window, we immediately send an alert. This catches both failed executions and jobs that don't run at all.

What alert channels do you support?

We support Email, Slack, Discord, Telegram, and custom webhooks. You can configure different channels for different severity levels and set up escalation rules.

Can I monitor webhooks from third-party services?

Absolutely! Seiri works with any system that can make HTTP requests. Monitor payment webhooks, CI/CD pipelines, scheduled reports, data syncs, and more. If it can ping a URL, Seiri can monitor it.

Is there an API for programmatic access?

Yes! Our REST API allows you to create monitors, retrieve statistics, manage alerts, and integrate Seiri into your existing tools and workflows. Full documentation is available for all endpoints.

How secure is my monitoring data?

Security is our top priority. All data is encrypted in transit and at rest. Each monitor gets a unique, unguessable URL. We're SOC 2 compliant and regularly undergo security audits. Your monitoring data is completely isolated between accounts.
