The problem

You shouldn't need five tools to understand your own infrastructure.

Most teams cobble together separate solutions for monitoring, alerting, log management, and incident response. Information lives in silos. When something breaks at 3 AM, you're SSH-ing into servers, grepping through logs, and trying to remember which domain runs on which server.

HostAtlas replaces that chaos with a single source of truth. One agent per server. One platform for everything. Every server, every service, every domain, every container — mapped, monitored, and observable from one dashboard.

Platform

Everything you need. Nothing you don't.

Six core capabilities that give you complete infrastructure visibility — from discovery to incident resolution.

travel_explore

Auto-Discovery

Automatically discover servers, services, domains, containers, and SSL certificates. No manual inventory. No stale spreadsheets.

 monitoring

Real-time Monitoring

CPU, memory, disk, network, load average — collected every 30 seconds. Domain health checks every 5 minutes. SSL expiration tracking.

 notifications_active

Smart Alerting

Threshold-based metric alerts with cooldown periods. Multi-channel delivery via Slack, email, PagerDuty, and webhooks. Escalation policies.

 emergency_home

Incident Management

Automatic crash detection with log collection, system snapshots, and timeline reconstruction. From detection to resolution in one place.

 favorite

Heartbeat Monitoring

Monitor cron jobs, background tasks, and CI/CD pipelines. Missed detection, job duration tracking, and grace period tolerance.

 receipt_long

Log Management

Access server logs without SSH. Real-time streaming, time-range filtering, and automatic log path discovery. Cloudflare LogPush integration.

How it works

From zero to full visibility in under five minutes.

Three steps. No complex configuration. No YAML files to write.

1

Install the agent

$ curl -sSL install.hostatlas.app | bash

A single command installs a lightweight Go agent on your server. Under 10 MB, no dependencies, runs as a system service. The agent communicates outbound only — no inbound ports required.

2

Auto-discovery begins

nginx detected — 3 domains found
mysql 8.0 — port 3306
redis 7.2 — port 6379
2 SSL certs — expires in 47d

Within seconds, the agent discovers running services (nginx, MySQL, Redis, PostgreSQL, Caddy), parses web server configs to find domains, detects Docker containers, and reads SSL certificates.

System metrics stream in every 30 seconds. Set threshold alerts, configure notification channels, and define escalation policies. When something breaks, HostAtlas detects it, collects logs, and creates an incident automatically.

Atlas Graph

See how everything connects.

The Atlas Graph is an interactive topology map of your entire infrastructure. Servers, services, domains, and containers — all visualized as an interconnected graph with real-time status indicators.

  • check_circle Color-coded nodes: blue for servers, green for services, purple for domains, orange for containers
  • check_circle Red ring indicators for offline or stopped nodes
  • check_circle Click any node to navigate directly to its detail page
  • check_circle Zoom, pan, and search across the entire graph

Auto-Discovery

No manual inventory.
No stale spreadsheets.

The HostAtlas agent runs a comprehensive discovery scan every 5 minutes. It detects running processes, parses web server configurations, reads Docker socket data, and validates SSL certificates — all without manual configuration.

dns

Service Detection

Nginx, Apache, MySQL, PostgreSQL, Redis, Caddy — detected with version numbers and ports.

language

Domain Extraction

Parses nginx configs, Apache virtual hosts, and Caddy domain blocks to find every hosted domain.

deployed_code

Container Discovery

Docker and containerd containers with image, status, and resource mapping.

verified

Certificate Tracking

Let's Encrypt and custom certificates with expiry dates and renewal detection.

Monitoring

Every metric. Every 30 seconds.

The agent collects system metrics at 30-second intervals and pushes them to the HostAtlas platform. CPU usage per core, memory breakdown (used, cached, buffers, swap), disk usage per mount point, network I/O, and system load averages.

Incident Management

When a service crashes, HostAtlas is already investigating.

Automatic crash detection with full log collection, system snapshots, and timeline reconstruction. No manual log grepping required.

crisis_alert

Step 2

Collect logs

Gathers error logs, syslog, dmesg from 5 min before to 2 min after crash.

Step 5

Follow-up

Collects follow-up logs 2 minutes later to capture restart attempts.

Heartbeat Monitoring

Your cron jobs.
Monitored.

Add a single HTTP call to your scheduled tasks. If HostAtlas doesn't hear from your job within the expected interval plus grace period, you get alerted immediately. Track job durations, detect missed runs, and monitor CI/CD pipelines.

Open Source

The agent is open source.
By design, not by accident.

The HostAtlas agent runs on your servers and collects sensitive infrastructure data. You deserve to know exactly what it does. That's why it's fully open source — every line of code is auditable, and every network call is transparent.

No hidden telemetry. No secret data exfiltration. No obfuscated binaries. Just a clean, well-documented Go codebase that does exactly what it says — collects metrics, discovers infrastructure, and reports back to your HostAtlas dashboard. Nothing more.

visibility

Full Transparency

Read every line of code. See exactly what data is collected, how it's transmitted, and what endpoints it communicates with. No surprises.

verified_user

Security You Can Verify

Run your own security audits. Review the agent's network behavior. Verify that it only communicates outbound to the HostAtlas API — nothing else.

handshake

Trust Through Openness

We believe trust is earned through transparency, not marketing claims. Open source means you don't have to take our word for it.

Community Contributions

Report issues, suggest improvements, or contribute code. The agent gets better because the community can participate directly.
