The standard open-source metrics/alerting system for cloud-native infrastructure - the pull-based model and query language (PromQL) are worth learning well.
Where prometheus fits, based on its real tags and topics.
git clone https://github.com/prometheus/prometheus.gitSee the repository's README for language-specific setup steps.

“The default choice for production React today - server components, file-based routing, and first-class deployment story make it the fastest path from idea to shipped app.”
The Postgres development platform. Supabase gives you a dedicated Postgres database to build your web, mobile, and AI applications.
“A genuinely open-source Firebase alternative - real Postgres underneath, with auth, storage, and realtime built in rather than a proprietary database.”
“Utility-first CSS that's become the default styling approach for new projects - fast to write, easy to keep consistent, no dead CSS to prune later.”
Find vulnerabilities, misconfigurations, secrets, SBOM in containers, Kubernetes, code repositories, clouds and more
“A fast, all-in-one vulnerability scanner - containers, filesystems, git repos, and Terraform/IaC misconfigurations all covered by one CLI tool.”
“The open-source engine behind Docker - understanding containers here pays off no matter which orchestrator sits on top later.”
“The standard open-source dashboarding tool - connects to nearly every metrics/logging backend and is usually paired with Prometheus.”
“A self-hosted PaaS that gives you Heroku-style deploys on your own infrastructure - the fastest path from git push to a running app without a cloud platform bill.”
“A newer, actively growing self-hosting platform that's quickly becoming a real Coolify alternative - worth watching if you're picking a self-hosted deploy tool today.”
“A more actively developed, plugin-extensible alternative to the stock Kubernetes Dashboard - worth trying if you outgrew the default UI.”
“Basically Wireshark for Kubernetes traffic - captures real API calls between services, which turns a guessing game of network debugging into an actual investigation.”
“The industry-standard container orchestrator - not always necessary at small scale, but the default assumption for any serious cloud-native platform team.”
“The most capable open-source relational database available - strong standards compliance, extensions for nearly everything (including full-text search and vectors), and a default choice for good reason.”
“Unifies dozens of LLM providers behind a single API, making model switching almost effortless in production.”
“The standard library for working with open-weight models - thousands of pretrained models are one line of code away.”
“The modern default frontend build tool - native ESM in dev means a dev server that starts and reloads almost instantly, even on large apps.”
“The most widely adopted framework for chaining LLM calls, tools, and retrieval into real applications - a near-default starting point for RAG and agent projects.”
