🐳 Introducing CapScope — Container observability that remembers what Docker forgets.

Ever had a Docker container crash at 3 AM, restart automatically, and take all its useful logs with it?

I've experienced how frustrating container troubleshooting can become when the evidence disappears.

So I built CapScope.

💀 1. The Problem

Most container dashboards tell you what's happening right now.

But what happens when a container dies?

Was it OOM killed? Did a deployment break something? Was there a restart loop? What did the application print before crashing?

CapScope is built to answer these questions.

🔍 2. What is CapScope?

CapScope is a lightweight, self-hosted container observability and crash-forensics platform built with Go.

It runs as a single container and uses SQLite for persistent storage.

No external database. No Prometheus. No Loki. No complicated monitoring stack.

📊 3. What can it do?

• Persistent container logs with full-text search
• Automatic crash snapshots
• Exit-code and OOM detection
• Restart-loop detection
• Historical CPU and memory charts
• Reverse-proxy access-log analytics
• Deployment markers
• Automatic secret redaction

💀 4. Crash Snapshots

This is one of my favourite features.

When a container exits, CapScope captures useful diagnostic context:

• Exit code
• Last log lines
• CPU and memory trends
• Crash classification
• Plain-language summary
• Deployment context

Instead of starting an investigation from zero, you have evidence to work with.

🏗️ 5. Who is it for?

CapScope is designed for:

• Homelab enthusiasts
• Docker self-hosters
• CapRover users
• Coolify users
• Dokploy users
• Portainer users
• DevOps and Platform Engineers
• Anyone running containers on a single server

🚀 6. Why another observability tool?

Because not every infrastructure setup needs a complete observability stack.

Sometimes you just need to know:

"What happened to my container before it died?"

CapScope focuses on that problem.

I'd love your feedback!

CapScope is an evolving open-source project.

What feature would you like to see next?

• Container-level alerts?
• Multi-host monitoring?
• Advanced crash analytics?
• More integrations?

Try it, explore it, report bugs, and share your ideas.

Let's make container forensics less scary.
