You can expose a local development server to receive webhooks from services like GitHub, Stripe, or Twilio by running cloudflared alongside a FastAPI application. This eliminates port forwarding, public IPs, and paid ngrok subscriptions entirely. Cloudflare Tunnels create an outbound-only encrypted connection from your machine to Cloudflare’s edge network, which then proxies incoming webhook requests back to your local FastAPI endpoint with full TLS, automatic reconnection, and zero firewall changes.

By combining Meilisearch v1.12’s fast REST API with HTMX 2.0’s hx-get and hx-trigger="keyup changed delay:300ms" attributes, you can build a real-time, typo-tolerant search interface that returns results in under 50ms - without writing a single line of custom JavaScript or pulling in React, Vue, or any frontend framework. The server renders HTML fragments that HTMX swaps into the DOM, keeping the entire search experience under 15 KB of total JS payload. What follows covers the full setup from Docker Compose to a working search UI with faceted filtering.

You can build a fully local, sandboxed code interpreter agent by pairing Ollama (running a reasoning model like Llama 4 Scout or DeepSeek R1) with a Docker container that executes the generated Python code. The agent sends a user prompt to the local LLM, which produces Python code; that code gets injected into a locked-down Docker container with no network access and strict resource limits; the stdout/stderr output is captured and fed back to the LLM for reflection and iteration. The entire loop runs on your machine with zero cloud API calls, giving you a private, free, ChatGPT Code Interpreter-style experience.

You have sent the message “it works on my machine” at least once in your career. Maybe you’ve been on the receiving end of it. Either way, the problem is always the same: two machines that are supposed to be identical are not, and no one can explain why. One has Python 3.11, the other has 3.12. One has a system-level OpenSSL that some C extension links against, and the other doesn’t. One engineer installed a package six months ago and forgot about it.

Gatus is a single-binary or single-container monitoring tool that continuously probes your services and renders a public status page at a URL you control. You define every check in one YAML file, so your entire monitoring setup can live in Git alongside the rest of your infrastructure. There is no mandatory database, no web-based configuration UI to click through, and no per-monitor pricing. If you self-host anything - a blog, a Gitea instance , a Home Assistant server, a mail relay - Gatus gives you a straightforward way to know when something breaks and to show your users that things are running.

If your Linux development workflow still depends on one or more VirtualBox VMs, you are not doing anything wrong. VirtualBox has been the default answer for isolated dev environments for years: predictable snapshots, clear network modes, and a full guest OS that behaves exactly like a separate machine.

But in 2026, most application development tasks do not need full hardware emulation. They need fast startup, easy sharing, consistent dependencies, and low resource overhead. That is exactly where Docker Desktop and docker compose shine.
