Know about an outage before your customers
A3.Observe checks websites, APIs, databases and queues, wakes the right person on call and keeps customers informed through the status page.
Free plan: 5 monitors, a status page and a team of up to three people.
One product instead of scripts and chats
From the first signal to a calm customer
Each stage of an outage has its own tool, and all of them know your products and resources.
- 1
Detect
Checks run from several regions and from inside your network. A majority decision filters out network noise.
- 2
Understand
The alert points to the root cause, and each run keeps the expected and actual value, timings and region.
- 3
Reach on-call
On-call schedules and escalation bring the alert to a person via Telegram, Slack, SMS or email.
- 4
Inform customers
The incident publishes updates to the status page, and subscribers receive them automatically.
Check every layer of the service
A website can still respond while the database, queue or mail server is already down. A3.Observe checks every layer with one tool and shows a clear error code.
Web
Website availability, response and certificate, WebSocket connection.
- HTTP
- SSL
- WebSocket
API
Multi-step scenarios, SignalR hubs and the standard gRPC health check.
- API
- SignalR
- gRPC
Network
Open port and service response, ping and DNS records.
- TCP
- ICMP
- DNS
Browser
User steps in a real browser: click, type, wait for text.
- Browser
Background jobs
A signal from cron jobs and backups. No signal on time means an outage.

- SMTP
- IMAP
- POP3

Less noise, faster response
The capabilities that make teams move beyond simple uptime checks.
Internal services without open ports
A private agent checks databases, brokers and APIs inside your network using outbound connections only.
One outage, one alert
Resource dependencies suppress the flood of alerts from dependent services, so the person on call sees the root cause right away.
On-call and escalation
Rotations, overrides and an iCal calendar. If nobody acknowledges an alert, it moves on step by step.
Customer updates in a minute
The AI assistant drafts incident updates and postmortems and translates the status page.
A status page that takes load off support
Show customers selected products, current incidents and maintenance on your own domain. Subscribers get updates by email, webhook or RSS, and a status badge goes on your website with one line of code.
- Your own domain and branding
- 90 days of uptime history
- Subscriptions by email, webhook and RSS
- Several languages translated by the AI assistant
